14.02 CORRECTION OF WORK AND CORRECTIVE ACTION PLANS
A. The Contractor must promptly correct Work rejected by Construction Manager or Work failing to conform to the requirements of the Contract Documents, whether or not Fabricated, Installed or completed, even if such non-conforming Work was previously inspected or approved by the City or the Construction Manager. The Contractor bears the costs of correcting such rejected Work, including additional testing and inspections required, and compensation for City provided services and expenses made necessary thereby.

B. The Contractor may take one of two actions to remediate Work that does not conform to the Contract Documents:

1. Contractor may, at his own expense, remove defective Work and install Work that complies with the Contract Documents;

2. Contractor may develop and submit to Construction Manager, as a Submittal (not an RFI), a Corrective Action Plan (CAP). The CAP describes possible solution(s) to address the defective Work including “work-arounds” that would leave the defective Work in place. To facilitate the City’s review and possible acceptance of the CAP the Contractor may employ the services of a licensed Engineer or Architect to develop, sign and stamp the CAP for submission to the City.

Alternatively, the Contract may submit a CAP that is more general in description and substance and leave it to the Design Engineer to evaluate and develop a formal solution.

The Contractor shall compensate the Design Engineer for costs incurred via City issuance of a deductive change order to the Contract.

3. In the event the City determines that a practical solution is not available that would enable the defective Work to be left in place, then the Contractor must remove the defective Work and build per the Contract Documents.

C. Notwithstanding Section 00700-14.02.A, in the event of an Emergency constituting an immediate hazard to the health or safety of City’s employees, agents, representatives, property, or licensees, City may undertake, at the Contractor's expense and without prior notice, all work necessary to correct such hazardous condition(s) when it was caused by work of the Contractor not being in accordance with requirements of the Contract Documents.

D. The Contractor must remove from the Project Site portions of the Work that are not in accordance with the requirements of the Contract Documents, and are neither corrected by the Contractor nor accepted by the City.

E. If the Contractor fails to correct nonconforming Work, as per Section 00700-14.02.A, or fails to remove nonconforming work, as per Section 00700-14.02.C, City may correct or remove the nonconforming Work per Section 00700-14.02.E.

F. If the Contractor does not submit a Corrective Action Plan or proceed with correction or removal of nonconforming Work, within such time fixed by the Contract Documents or written notice from Construction Manager, the City may remove and store the salvable materials, articles and/or equipment at the Contractor's expense. If the Contractor does not pay all costs of such removal and storage within fourteen (14) Days after written notice, City may, upon fourteen (14) additional Days written notice, sell such materials articles and/or equipment at an auction or private sale, and shall account for the proceeds thereof, after deducting costs and damages that would have been borne by the Contractor, including compensation for City services and expenses made necessary thereby. If the proceeds of a sale do not cover all costs that the Contractor would have borne, the Contract Sum will be reduced by

H. Nothing contained in this Section 00700-14.02, Correction of the Work and Correction Action Plans, establishes a period of limitation with respect to other obligations that the Contractor might have in the Contract Documents. Establishment of the Warranty/Guarantee period(s), as described in Section 00700-15.12, Warranties & Guarantees, relates only to the specific obligation of the Contractor to correct the Work, and has no relationship to the time within which the obligation to comply with requirements of the Contract Documents may be sought to be enforced, nor to the time within which proceedings may be commenced to establish the Contractor's liability with respect to the Contractor's obligations other than specifically to correct the Work.

14.03 ACCEPTANCE OF NONCONFORMING WORK
A. If City prefers to accept any or all of the Work that is not in accordance with requirements of the Contract Documents, City may do so instead of requiring its correction and/or removal, in which case the Contract Sum will be reduced as appropriate and equitable. Such adjustment shall be effected whether or not Final Payment to the Contractor has been made.

1.03 SUMMARY
A. The Progress Schedule for this Project will also be referred to as the Critical Path Method (CPM) Schedule. A CPM network schedule is a graphical depiction of the Contractor’s construction plan, showing the sequential activities necessary to complete the Work within the specified contract times and constraints. The CPM network schedule for this project shall depict events and tasks as activities, showing their interrelationships, and shall identify the progress required for each activity before subsequent activities can start. Activities shall be logically presented in a network showing the activities' interrelationships chronologically. Because each activity has an assigned duration, the completed network shall show the critical path of activities that must be completed on time to ensure timely project completion. The earliest and latest start and finish times for each activity shall also be shown. The CPM network shall be comprehensive and shall include all interdependencies and interactions required to perform the Work.

B. The construction schedules and accompanying reports outlined in this section are important to the City as they budget, plan and administer the project. The City, Construction Manager and/or Engineer will regularly analyze the most current progress schedule during construction to monitor progress status of the project relative to contract times. The Schedule Updates and Weekly Schedules will be an agenda item at all project coordination meetings as project participants work together in prioritizing their respective tasks and action items to efficiently perform their duties.

C. The Time Impact Analyses are very important submittals to the Construction Manager and City as they evaluate activity durations and the relationships between activities before deciding on possible changes to the contract time and/or viable options to mitigate time impacts.

D. By submitting a bid for this Project, the Contractor represents to the City that Contractor will have included all costs within its Total Bid Price to fully comply with all scheduling and reporting requirements hereinafter prescribed in this Section.

1.04 RESPONSIBLE SCHEDULING PERSON

In the event the Contractor does not have an employee with the required scheduling qualifications, as determined by the Construction Manager, the Contractor will be required to employ a qualified CPM scheduling consultant who regularly performs these services and who in the opinion of the Construction Manager possesses the required scheduling qualifications and availability to perform the CPM scheduling for this Project.

F. Construction Manager reserves the right to remove scheduler from the project if found to be incompetent.

1.05 SCHEDULING FORMAT AND SOFTWARE
A. Schedule Format: Utilize critical path method (CPM) format utilizing Precedence Diagramming Method.

B. Prepare computerized schedules utilizing Oracle Primavera Professional Project Manager (P6) PPM scheduling software compatible with Windows 8 or later version or Microsoft Project Professional 2016 or later version compatible with Windows 8 or later version.

1.06 PRECONSTRUCTION SCHEDULING MEETING AND PREPARATION A. The Construction Manager will conduct a Preconstruction Scheduling Meeting with Contractor’s Project Manager and Responsible Scheduling Person within seven days (7) calendar days after approval of the Contractor’s designated Scheduler. This meeting is separate from the Preconstruction Conference Meeting and is intended to only cover schedule requirements for this project. These requirements would include formatting, color coding, activity detail, coding structure, calendar requirements, reporting requirements, updates, revisions, and schedule delay analysis.

B. Contractor shall present their schedule methodology, planned sequence of operations and proposed activity coding structure.

1. The coding structure shall, at a minimum, include code fields for Project Segment or Phase, Area of Work, Type of Work, Submittal/Procurement/Construction and Responsibilities (this would include all subcontractors).

3. The Contractor shall include with the Baseline Schedule Submittal a signed statement from each Subcontractor listed on the Contractor’s Section 00430, DESIGNATION OF SUBCONTRACTORS, which confirms they have evaluated the Contractor’s Baseline Schedule and agree that the Baseline Schedule accurately depicts the quantity, logic and durations for all activities assigned to their company.

4. The Construction Manager will review the schedule and provide any comments, its favorable review of the schedule, or request a meeting to review the schedule with the Contractor within fifteen (15) days of receipt of the schedule. If requested, the Contractor shall participate in a review and evaluation of the proposed network diagrams and analysis by the Construction Manager. Any revisions necessary as a result of this review shall be resubmitted for review by the Construction Manager within ten (10) days. When completed, the favorably reviewed schedule shall then be the schedule to be used by the Contractor for planning, organizing, and directing the work, and for reporting progress. If the Contractor thereafter desires to make significant changes in its method of operating and scheduling, the Contractor shall notify the Construction Manager in writing stating the reasons for the change.

5. No more than two (2) progress payments will be made prior to submission and acceptance of the CPM Baseline Schedule by the Construction Manager.

6. Failure to include an activity required for execution of the Work does not excuse Contractor from completing the Work and portions thereof within specified contract times and contract price. Failure of Contractor to include required schedule constraints, sequences or milestones in schedule shall not relieve Contractor of obligation to conform to requirements of Contract. Acceptance of schedule shall not waive Contract requirements. In event of conflict between accepted schedule and Contract requirements, terms of Contract shall govern at all times, unless requirements are waived in writing by the City.

7. Contractor shall not unilaterally change the accepted Baseline Schedule without the prior written notification to and acceptance and consent of the Construction Manager, excepting only the reporting of Actual Start, Actual Finish, and Activity Progress.

If the Contractor’s schedule is based on less time than the maximum time allowed for milestone(s) or Contract completion no compensation for extended overhead expenses will be considered until the expiration of the entire time periods provided for in the Contract as adjusted by any time extensions granted other than compensable time extensions.

5. Acceptance of the Contractor’s Base CPM Schedule, monthly updates or revised schedule, when based on less time than the maximum time allowed for milestone(s) or Contract completion does not serve to change any Contract duration, nor serve as a waiver of the Contractor’s nor the City’s right to utilize the full amount of time specified in the Contract, unless so modified in a Contract Change Order.

6. Prepare schedule utilizing activity durations in terms of working days. Do not exceed fifteen (15) working day duration on activities except concrete curing, submittal review, and equipment fabrication and deliveries.

a. Which activities must be completed before subsequent activities can be started? b. Which activities can be performed concurrently?
c. Which activities must be started immediately following completed activities? d. What major facility, equipment or manpower restrictions are required for sequencing these activities?

8. Resource Loading and Leveling: The CPM Schedule shall not incorporate resource loading and leveling. The Contractor shall provide hard coded logic constraints as necessary to incorporate any resource requirements that may be applicable to the Project construction.

The Contractor shall determine and allocate the proper resources to complete the Project by the specified Contract completion date.

9. Network Activities- The selection and number of detailed network activities shall be subject to favorable review by the Construction Manager and shall meet the following requirements:
a. All Work activities should be of sufficient detail to ensure adequate planning and execution of the Work and such that schedules provide an appropriate basis for monitoring and evaluating the progress of the Work. A work activity is defined as a single task that requires time and resources (manpower, equipment and/or material) to complete in a continuous operation, excluding submittal activities, review/acceptance activities, and fabrication/procurement activities. Durations for on-site work activities shall be in working days and shall not exceed ten (10) workdays. Passive on-site activities such as curing and testing periods can be in calendar days if desired by Contractor. All such passive on-site activities shall be included in the Contractor’s schedule and durations should be as specified in the Contract Documents. b. The submittal and approval of samples and equipment, fabrication of special material and equipment and their installation and testing. Should the Contractor expect multiple submittals and deliveries for materials or equipment from the same supplier, the Contractor shall show each planned submittal and delivery and the logic to the respective on-site Work activity(s).
c. The critical path shall be shown on all reports and on the graphic network logic diagram. The activities which constitute the critical path shall be identified.

Progress Schedules and Reports Municipal Well 3
d. Progress milestone events or other significant stages of completion, as defined in Section 00510, Agreement, Article 4 – Contract Times. System shutdown and tie-in dates must be identified and included in the schedule.
e. The lead time required for testing, inspection and other procedures required prior to acceptance of the work. All witnessed factory tests shall be shown as individual activities.
f. The activity numbers shall be grouped by responsibility, phases, milestones, work area, trade and subcontractor to provide logical summary activities. g. All activities of the City and the Construction Manager that affect progress along with required contract dates for completion of all parts of the work. h. All activities of utilities, regulatory agencies and permitting agencies. i. All mobilization and demobilization activities, including temporary controls. j. Schedule shall show all hydraulic testing of structures, pipe testing, field testing, training and demonstration periods as required. Field testing and training activities should be broken down to reflect all individual system and equipment components. k. Float shall not be an activity unless approved by the Construction Manager.

10. Network Logic Diagram- The graphic network diagram shall include for each activity, the description, activity number, the estimated duration in workdays, and all activity relationship lines. The network diagram shall be drawn for the early start and early finish of all activities.

The diagrams shall show elements of the project in detail and an entire project summary.

Diagrams shall show the order and interdependence of all activities and sequence in which the work is to be accomplished as planned by the Contractor and its subcontractors. The basic concept of a network analysis diagram shall be followed to show how the start of a given activity is dependent on the completion of preceding activities and its completion restricts the start of following activities. The Primavera layout of the network logic diagrams shall be time-scaled and show the following as a minimum:
a. Activity numbers and description.
b. Activity duration and total float.
c. Critical path, highlighted in red color.
d. Relationships between activities and lag times, if any. e. Start, completion and milestone dates.

11. Float:
a. “Total Float" or “Float” shall be defined as the difference between the early finish and late finish dates for an activity. On the CPM Schedule delineate the specified Contract duration and identify the planned completion of the Work as the final finish milestone.

The time period between these two dates, if any, shall be considered float. Float in any activity, milestone completion date or Contract completion date shall be considered a resource available to both the City and the Contractor. Neither the City nor the Contractor has ownership of the float.
b. The parties agree that float, as properly shown on the baseline schedule and all updates thereto, is not for the exclusive benefit of either party. Consequently, either party may, without liability to the other for actual or liquidated damages for delay, delay a schedule activity provided that such delay shall not cause the float of the affected activity to become negative. If the float of the activity is already negative, as shown on the most recent schedule update, either party may delay such activity, without liability to the other for actual or liquidated damages for delay, provided that such delay shall not cause the negative float of the delayed activity to exceed the negative float of all other schedule activities. If the project has interim milestones with separate liquidated damages, only delays by the City to the Project Critical Path shall potentially entitle the Contractor to extended overhead costs and only subject to the limitations of General Conditions 8.04, Time Extensions.

December 2024 01324 - 6 City of Yuba City
Progress Schedules and Reports Municipal Well 3
c. Pursuant to these float sharing requirements, use of float suppression techniques such as preferential sequencing or logic, special lead or lag logic restraints, extended activity duration’s or imposed dates shall be cause for rejection of any schedule submittal.

12. City-furnished Equipment or Materials (If Applicable):
a. Immediately after Award of Contract, Contractor shall obtain from Construction Manager anticipated delivery dates of City-furnished equipment or materials if they are not already specified in the Contract Documents.
b. These dates shall be shown on Baseline Construction Schedule in same manner indicated by Construction Manager.

1.08 WEATHER CONDITIONS AND WEATHER DAY ALLOWANCE
A. Seasonal weather conditions shall be considered in the planning and scheduling of work activity durations influenced by high or low ambient temperatures or precipitation to ensure the completion of the Work within the Contract Time. No time extensions will be granted for the Contractor's failure to take into account such weather conditions for the location of the Work and for the period of time in which the Work is to be accomplished.

B. The expected loss of working three (3) days shall be included in a separate identifiable critical activity labeled "Weather Days Allowance" to be included as the last critical activity of the project schedule. When weather days are experienced, and are approved as such by the Construction Manager, the Contractor shall either:

1. Increase the duration of the current critical activity(ies) by the number of weather days experienced.

2. Add a critical activity to the schedule to reflect the occurrence of the weather day(s).

C. The duration of the weather day allowance activity shall be reduced as weather days are experienced and included in the schedule. Any remaining weather days in the weather day allowance activity at the completion of the project shall be considered as float and shall not be for the exclusive use or benefit of either the City or Contractor.

1.09 UPDATING THE BASELINE SCHEDULE
A. Contractor shall update the Baseline Schedule on a monthly basis (or at shorter intervals if deemed necessary by Construction Manager to identify corrections necessary, such as work activities ten (10) days or more behind schedule) for the purpose of recording and monitoring the progress of the work. The Updated Baseline Schedule shall incorporate changes mutually agreed upon by Contractor and Construction Manager during preceding periodic reviews and changes resulting from approved Change Orders and Field Orders.

B. The Contractor shall produce and provide four (4) complete sets each of time-scaled network logic diagrams and bar charts in color on 11-inch by 17-inch sheets and one electronic copy on a CD with data in native format. The network logic diagram shall be clear and legible. Critical activities shall be indicated in red color on both schedules.

1. The City will not make monthly progress payments to the Contractor until the Construction Manager has received and accepted all schedule updates and reports as herein specified:
a. The Contractor shall submit schedule updates and reports to Construction Manager at least five (5) days before Contractor’s submission of its request for progress payment for same monthly period.

Progress Schedules and Reports Municipal Well 3

1.10 SCHEDULE REVISIONS
A. The conditions under which the Construction Manager may require revisions of the Construction Schedule include the following:

1. When delay in completion of any work item or sequence of work items results in an estimated extension of project completion by either fifteen (15) working days or by five percent (5 percent) of the remaining duration of time to complete the Contract, whichever is less. This slippage duration may be reduced further for any contract time that is a critical fixed completion date which must be met.

2. When delays in submittals or deliveries make re-planning or re-scheduling of the work necessary.

3. When the schedule does not represent actual prosecution and progress of the work.

4. When any change to the sequence of activities, the completion date for major portions of the work, or changes occur which affect the critical path.

5. When Contract modification necessitates schedule revision.

1.11 WEEKLY SCHEDULE
A. Submit to Construction Manager, on the last working day of every week, a progress schedule showing the activities completed during the previous week and the Contractor's schedule of activities for the following three (3) weeks.

B. The Weekly Schedule may be a CPM schedule or a bar chart but shall utilize the logic and conform to the status of the current progress schedule. In the event that the Weekly Schedule no longer conforms to the current schedule Contractor may be required to revise the schedule in accordance with Article, "Revisions to Schedule".

C. The activity designations and activity numbers used in the Weekly Schedule shall be consistent with those used in the Baseline Schedule and the monthly Schedule Updates.

D. The format of the Weekly Schedule shall be as agreed upon between the Contractor and the Construction Manager.

1.12 TIME IMPACT ANALYSIS
A. When change orders are initiated, delays are experienced, or the Contractor desires to revise the schedule logic, the Contractor shall submit to the Construction Manager a written Time Impact Analysis illustrating the influence of each change, delay, or Contractor request on the current contract schedule completion date. Each Time Impact Analysis shall include a fragmentary network analysis demonstrating how the Contractor proposes to incorporate the change order, delay, or Contractor request into the Schedule. The analysis shall demonstrate the time impact based on the date of occurrence of the change, delay or revision; the status of construction at that point in time; and the impact of all affected activities. The event times used in the analysis shall be those included in the latest updated copy of the CPM Schedule or as adjusted by mutual agreement between the Construction Manager and Contractor.

B. Activity time delays will not automatically mean that an extension of Contract Time is warranted or due the Contractor:

1. It is possible that a strike or contract modification will not affect existing critical activities or cause non-critical activities to become critical, i.e., a strike or modification may result in only absorbing a part of the available total float that may exist within an activity chain of the network, thereby not causing any effect on the Contract completion date or time.

2. The Contractor acknowledges and agrees that mitigation for delays due to changes, differing site conditions, suspension of the Work and other causes will require revision of preferential sequences of the Work before proposing an updated schedule which supports

December 2024 01324 - 8 City of Yuba City
Progress Schedules and Reports Municipal Well 3
a delay to the Project as a whole. When a delay to the Project as a whole can be avoided by revising preferential sequencing, and the Contractor chooses not to implement the revisions, the Contractor will be entitled to a time extension but is not entitled to compensation for extended overhead.

3. Float or slack shall not be for the exclusive use or benefit of the City or the Contractor.

Extensions of time for performance will be granted only to the extent that the equitable time adjustments for the activity or activities affected exceeds the total float along the activity chain involved at the time the change was ordered or the delay occurred.

C. Time Impact Submittal and Review:

1. Time Impact Analyses shall be submitted in triplicate and within fifteen (15) days after a delay occurs or with the Contractor's cost proposal in response to a notice of change from the Construction Manager. In cases where the Contractor does not submit a Time Impact Analysis for a specific change order, delay, or Contractor request within the specified period of time, then it is mutually agreed that the particular change order, delay, or Contractor request has no time impact on the Contract completion date and no time extension is required:
a. Approval or rejection of Time Impact Analyses by the Construction Manager and the City will be made within fifteen (15) days after receipt of the Time Impact Analysis unless subsequent meetings and negotiations are necessary. b. Upon approval, a copy of the Time Impact Analysis signed by the Construction Manager and City will be returned to the Contractor.
c. Upon mutual agreement by both parties, schedule revisions illustrating the influence of change orders, delays, and/or Contractor requests will be incorporated into the next schedule update.

1.13 RESPONSIBILITY FOR COMPLETION
A. Contractor agrees that at the sole judgment of Construction Manager, whenever it becomes apparent from the current monthly Updated Contract Baseline Schedule that the contract completion date and/or any milestone dates will not be met, Contractor will take the appropriate following actions, acceptable to Construction Manager, at no additional cost to City:

1. Increase construction labor in such quantities and crafts as will substantially eliminate, in the judgment of Construction Manager, the backlog of work.

2. Increase the number of working hours per shift, shifts per working day, working days per week, or the amount of construction equipment, or any combination of the foregoing, sufficiently to substantially eliminate, in the judgment of Construction Manager, the backlog of work. This paragraph shall not be construed to allow work outside the allowable hours and days specified in the Contract Documents.

3. Reschedule activities to achieve maximum practical concurrence of completion of activities.

1.14 FINAL SCHEDULE SUBMITTAL
A. As a condition precedent to the release of retainage the final Schedule Update shall be identified by the Contractor as the As-Built Schedule.

B. The As-Built Schedule shall reflect the exact manner in which the project was constructed by reflecting actual start and completion dates for all activities accomplished on the project.

C. The As-Built Schedule shall be signed and certified by the Contractor’s Project Manager and Responsible Scheduler as being an accurate record of the way in which the project was actually constructed.

8. If at any time the drilling fluid is not in compliance with these Technical Provisions or the recommendations of the drilling fluid engineer, as approved by the Engineer, the properties shall be adjusted, and the tests rerun until the drilling fluid obtains the specified characteristics. If the specified properties cannot be maintained, the drilling fluid shall be replaced at the Contractors expense.

If the logging tools fail to reach the desired depth, the Contractor, at the Contractor’s expense, shall reinstall the drilling tools into the borehole, clean out the borehole to the final drilled depth, and recondition the hole to allow for logging operations.

4. Upon completion of logging, the Contractor will deliver to the Engineer four (4) field prints and a digital file of the geophysical surveys, including the raw data (e.g., .las files). The Engineer shall approve the field copies of the surveys before the Contractor releases the logging service company from the site.

F. Caliper Log

1. When drilling has reached the prescribed final depth, the Contractor shall conduct a caliper survey to confirm the diameter of the borehole. The caliper survey will be used to verify the quantities of gravel that will be required for later installation during

20 the well construction.

2. If at any point within the intake or screened portion of the well, a minimum gravel pack thickness of 5 inches cannot be achieved, the borehole will be considered unacceptable for completion. The Contractor shall then proceed to ream the hole at the Contractor’s own expense. A second caliper log shall be conducted on completion of the reaming, at the expense of the Contractor, to satisfy the requirements of the Contract. If the borehole remains unacceptable and it is determined that the well cannot be reasonably constructed to satisfy these Technical Provisions, the Contractor shall abandon the hole and re-drill the well at a new location on the site, all in accordance with the requirements of Section 3.15 and Section 3.16.

The Contractor will not be required to return to the bottom with the drilling tools if the casing installation immediately follows the caliper survey, assuming acceptable results are achieved.

A. Tremie, Accessory Pipes, and Casing Installation

1. A tremie pipe having a minimum inside diameter of 2 inches shall be run into the borehole to the specified casing installation depth. Circulation shall commence 30 minutes prior to casing installation and continue until the start of gravel packing.

Circulation shall commence using drilling fluid from the circulation tanks of the same viscosity as that in the borehole and thinned using clean water containing less than 2 percent solids. With the tremie pipe remaining in the borehole, casing installation shall proceed in accordance with the specified well design.

2. Circulation through the tremie pipe shall continue during the casing and screen

21 installation.

3. Three-inch steel pipe shall be used as a gravel fill pipe. The pipe shall be installed to the depth specified in the Plans. The pipe assembly shall be butt welded together to provide a watertight seal. The gravel fill pipe shall be pulled to the side and welded to the conductor casing at ground level, as shown in the Plans.

Orientation of the 3-inch pipe shall be offset from the future pump discharge side of the well as specified in the Plans.

The sounding pipe shall be pulled to the side and welded to the conductor casing at ground level, as shown in the Plans. Orientation of the 2-inch pipe shall be offset from the future pump discharge side of the well as specified in the Plans.

7. The casing shall be suspended in tension from the surface by means of an appropriate hanger or clamp. The use of float plugs to land and set casing will not be permitted. The bottom of the casing assembly shall be at a sufficient distance above the bottom of the borehole to ensure that none of the casing assembly will be supported from the bottom of the hole. Verification of this requirement will be confirmed by the Engineer by observation of the total weight suspended by the drill rig on the weight indicator.

8. If, for any reason, the casing assembly cannot be landed in the correct position or at a depth acceptable to the Engineer, the Contractor shall remove the casing and screen from the well and ream the borehole. In no event shall the Contractor attempt to drive or "spud" the casing and screen assembly. If problems arise that prevent the Contractor from completing the well, it will be considered rejected, and the provisions of Section 3.15 will apply.

9. The casing shall be centered in the conductor casing. Failure to center the casing in the conductor will be grounds for rejection, and the provisions of Section 3.15 will apply.

B. Casing and Accessory Pipe Stick-up

22 1. The well casing assembly and accessory pipes shall be installed with a minimum of 3 feet of stick-up above the existing ground level.

C. Preliminary Plumbness and Alignment Survey - A preliminary test to examine the plumbness and alignment of the casing may be made by the Contractor after the casing has been installed in the borehole and before gravel packing is commenced. The intent of preliminary testing is to identify any plumbness and alignment problems so that they may be corrected before installation of the gravel envelope. Any determination made by the Contractor concerning the plumbness and alignment of the well at this point in construction shall not relieve the Contractor of the requirements specified in Section 3.14.

Any measures required to correct faulty plumbness and/or alignment shall be at the Contractors own expense.

4. Gravel packing shall continue uninterrupted until the gravel pack material is installed to the specified depth.

B. Attaining Proper Fill - The quantities of gravel placed in the annulus of the well shall not be less than the computed volume calculated from the caliper log and verified by the Engineer. A quantity less than the computed value may be judged as an indication of voids, and corrective measures may be required of the Contractor. Significant

23 differences between the estimated and total volume of gravel installed in the well may be grounds for the rejection of the well under Section 3.15.

C. Consolidation Using Swab Tool - Immediately following the gravel packing, the gravel pack shall be consolidated to ensure that no voids in the gravel pack exist. This can be accomplished with a swab or bailer lowered in the well and moved up and down for a minimum of one hour. After consolidation, the gravel level shall be measured to determine if consolidation has occurred. If the gravel level has dropped, additional gravel shall be added to bring the gravel level to the specified level and swabbed or bailed again. This process will be repeated until the gravel level is stable at the level specified in the plans. A detailed record shall be kept of the amount of gravel added during placement and consolidation, and the quantity of gravel placed in the annulus shall be at least the calculated volume of the annulus. The contractor shall submit the record indicating the total volume of gravel used and the calculated volume of the annulus to the Engineer. The Contractor shall measure and record the depth to the top of the gravel pack within the gravel fill pipe and ensure that it coincides with the bottom, open end of the gravel fill pipe so that there is no gravel pack within the gravel feed tube.

D. Fine Sand Transition Seal - A five-foot, fine sand transition seal consisting of #30 sand shall be placed on top of the consolidated gravel envelope via the tremie pipe. The transition sand shall be clean and delivered to the project site in pre-packaged 50-pound sacks.

3.7.3. Annular Sealing Method

The bottom of the tremie pipe shall remain submerged in the grout sealing material, maintaining a positive displacement throughout the sealing process until the grouting material has reached the ground surface.

C. The Contractor shall take measures to ensure that the weight of the cement column does not collapse the well casing during the sealing operation.

D. The annular seal will be required to be placed in three lifts as specified on the Plans. Each lift shall be allowed to be set for a minimum of two hours before placement of subsequent lifts.

E. Well development shall not commence until a minimum of 24 hours after placement of the seal.

Initially, and within 24 to 36 hours after completion of the annular sealing operation, the well shall be cleaned of residual drilling fluids by displacing the well through an open-ended drill pipe or tubing set in the well sump. This process shall be conducted for a minimum of 4 hours and until the discharge is clear of residual drilling fluids. After drilling residues have been displaced from the well, the development tool shall be installed in the well.

2. Swabbing/Airlifting
Swabbing and airlifting shall be conducted with the development tool alternately over no more than the length of one joint of drill pipe until that section of the screen is fully developed.

Swabbing and airlift pumping operations will be conducted from the top screen section to the bottom, alternately over no more than the length of one joint of the drill pipe.

Screen sections will be swabbed and pumped for a minimum of 7 minutes per foot of well screen or until cleaned of all drilling fluids. During pumping, the drill pipe shall be continuously moved up and down to achieve a swabbing action and uniform pumping across the screen section.

After the initial swabbing-airlift pass, a solution of potable water and Baroid “Aqua Clear PFD” product, or approved equal, shall be placed in the well. The product shall be mixed at the surface in the manufacturer-recommended proportion and injected evenly across each screened section of the well. The solution shall be displaced by adding a volume of potable water equal to the inside of the drill pipe and swabbed without airlifting. After placement of the solution, the well shall then remain idle for a period of 12 hours. Swabbing and airlift pumping of the well shall then resume from the top screen section to the bottom for a minimum of 5 minutes per foot of well screen.

If there continues to be circulation of sand, silt, mud, or water with a turbidity in excess

26 of 25 Nephelometric Turbidity Units (NTU) to the surface from the section of screen being cleaned, additional swabbing and pumping shall be performed until the section is cleaned of such material. It is anticipated that the mechanical development described above will take on the order of 12 minutes per foot of well screen.

2. The sounding pipe and gravel fill pipe shall be cleaned by circulating water and a solution of potable water and Baroid “Aqua Clear PFD” through the pipes.

3. The level of the gravel in the gravel fill pipe shall be measured periodically during well development operations. Gravel must not be added to the gravel fill pipe without prior authorization of the Engineer.

B. Well Video
After completion of swab/airlift operations, the Contractor shall conduct a video survey of the screen assembly. The survey shall be witnessed by the Engineer. The camera shall be in color and have side-scan capability. The logging speed of the video survey shall not exceed 30 feet per minute. The record of survey shall be recorded in DVD or mp4 format and shall be submitted to the Engineer.

The purpose of the video survey is to visually confirm that all drilling fluids, mud, debris have been removed from the well screens to the satisfaction of the Engineer.

If the Engineer determines that there is blockage of screens with drilling mud or any other material, the Contractor shall, at his own expense, continue swab/airlift operations until such material has been removed. If additional swab/airlift operations are required, a second video, at the Contractors expense, shall be performed.

C. Final Development

1. Upon completion of the swabbing and airlift pumping operations, a turbine pump and piping assembly shall be installed. No foot valve shall be installed on the pump and the gearhead shall not be equipped with a non-reverse ratchet installed.

2. Development pumping shall commence within 10 working days after the completion of Initial Development. Pumping shall be initiated at the lowest pumping (i.e., flow) rate possible with the installed pumping equipment. Throughout development pumping, the well shall be surged frequently to achieve maximum compaction of the gravel pack and to remove residual drilling fluids and wall cake. Surging and pumping will continue until the water produced is clear and sand-free, at which time the pumping rate will be increased in increments of 250 gallons per minute, and the pumping and surging will resume. This process will be repeated until the capacity of the well achieves a minimum of 150 percent of the design capacity of the well unless the Contractor is directed by the Engineer to pump the well at lower capacities.

3. Development records shall be maintained at a frequency of at least every 30 minutes showing pumping rate, static water level, pumping water level, drawdown, sand production, and any other pertinent information concerning well development.

Development pumping shall continue until the following conditions have been met:
a) The specific capacity (gallons per minute per foot of drawdown) no longer increases at the design capacity of the well.
b) The sand content satisfies the requirements of these Technical Provisions

27 as specified in Section 3.8.5.C.5

4. Development pumping shall be conducted for a minimum of 24 hours.

5. Sand Testing
The equipment for sand testing shall be the Rossum Centrifugal Sand Sampler. Sand continent shall be measured over a 30-minute interval after a surge at the target well capacity. The sand content shall be measured and recorded every minute over the 30 minutes of pumping after surging. The average sand content for any 5-minute period shall not exceed 5 parts per million during the 30-minute test. If the average sand content exceeds 5 parts per million for any 5-minute period, the Contractor, at Contractor’s expense, shall do the necessary redevelopment work until the sand content is 5 parts per million or less.

Sand testing shall be witnessed by the Engineer.

3.8.6. Well Performance Requirements
At the conclusion of well development, it is the responsibility of the Contractor to meet the requirements contained in Section 3.14 of these Technical Provisions. If the Contractor fails to meet these requirements after the development pumping operations, development shall continue at the Contractor's expense until the well satisfies the specified performance criteria.

3.9. Well and Aquifer Testing

3.9.1. Scope
After final development and when the well meets the specified performance requirements, tests will be performed, including an 8-hour step pumping test at capacities of 50, 75, 100, 125, and 150 percent of the target design capacity of the well and a 12-hour aquifer test at the final design capacity as determined by the Engineer based upon evaluation of well performance during the step test. The test capacities may be modified by the Engineer before or during the testing based on the results of development and test pumping. Well and aquifer testing shall not exceed 40 hours without written direction from the Engineer/Owner.

3.9.2. Test Pumping Procedures
A. Static Water Level
At the start of each day of pumping, the Contractor shall record the static water level in the well. At all other times, the static water level shall be considered to be attained when three successive water level measurements spaced ten minutes apart show no appreciable change.

B. Flow Metering

1. During each test or step, the discharge of the pump shall be measured with an accurate, calibrated totalizing and instantaneous flow meter, or other type as approved by the Engineer. The pump discharge rate shall be maintained at all times during the test within plus or minus 5 percent of the pump test rate by means of an approved gate valve in concert with engine speed.

2. Throughout the test, the Contractor shall frequently record flow rate and totalizer readings to ensure that the pumping rate remains constant.

28 C. Measurements

1. The Contractor shall measure the depth to water, flow rate, and sand content at the time intervals specified herein to the nearest 0.01 feet.

2. Each pumping test shall be monitored by the Contractor, with data recorded according to the following applicable time schedules:
a) Turn pump on to approved test pumping capacity at time (t) = 0. b) Contractor shall measure and record the depth to water as follows:
- each minute, from t = 1 to t = 10.
- each 2 minutes, from t = 10 to t = 20.
- each 5 minutes from t = 20 to t = 50.
- each 10 minutes from t = 50 to t = 100.
- at t = 120, t = 150, t = 180, t = 240, and t = 300.
- each 100 minutes after t = 300.
c) Each recovery test shall be recorded according to the following applicable schedule:
d) Contractor shall measure the depth to water and record as follows (t' refers to the time since pump shut off):
- each minute, t' = 1 to t' = 10
- each 2 minutes, t' = 10 to t' = 20
- each 5 minutes, t' = 20 to t' = 50
- each 10 minutes, t' = 50 to t' = 100
- at t' = 120, t' = 150, t' = 180, t' = 240, t' = 300
D. Pump Failure
In the case of failure or interruption of the pump operation for a period greater than one (1) percent of the elapsed pumping time from t = 0, the test shall be suspended until the static water level has been attained. Should the test be aborted as a result of a deficiency on the part of the Contractor's equipment or personnel, all time consumed in waiting for complete water level recovery and in resuming the pump test to the point where it was aborted shall be at no cost to the Owner.

E. Completion
After the well testing has been completed, the record of water level measurements shall be delivered to the Engineer on the forms provided as part of these documents. The test pump shall not be removed from the well until the Engineer has evaluated the data and authorized its removal.

3.9.3. Dynamic Flowmeter (Spinner) Survey
A vertical flowmeter (spinner) survey shall be conducted in each well during the 12-hour constant rate test. The type of spinner survey tool used shall be capable of accurately measuring flows from each screened section at the pumping rate during the constant rate test.

29 The survey shall be run after the pumping level has stabilized, which will be determined in the field by the Engineer. A dynamic test and static stop counts shall be made under pumping conditions from above the screen section to below of the screen interval. Three down runs shall be conducted during dynamic testing at rates of 20, 40, and 60 ft per minute. Each static stop count test shall consist of two-minute readings made at 10-foot increments. The record for the test shall indicate either meter speed or percentage of total meter speed with depth.

The meter used for the survey shall be calibrated within the uppermost and lowermost blank sections of the well casing.

The Contractor shall provide five (5) copies of the survey to the Engineer upon completion.

Calculation of flow rates and the percentage of each flow rate, from the screened interval, shall be performed by the logging subcontractor and submitted to the Engineer in tabular format.

The spinner survey measurements shall also be provided electronically to the Engineer in both Adobe PDF and ASCII digital format.

3.9.4. Water Samples
During constant rate testing of the well, the Contractor shall provide access to the well for sample collection by the Engineer.

3.9.5. Records
The Contractor shall keep accurate records of the pumping tests and furnish copies of all records to the Engineer upon completion of the test. The records shall be available to the Engineer for inspection at any time during testing. The records shall also include a description of the point from which depth to water measurements were made and its measured height above land surface.

3.10. Plumbness and Alignment Testing

3.10.1. Scope
This item shall consist of testing to determine the plumbness and alignment of the installed casing in the well. The plumbness and alignment test may be performed at any time following gravelpacking and sealing operations. The completed well shall be constructed round, plumb, and true to line as defined herein.

A. Alignment Equipment - Alignment shall be tested with a section of pipe 40 feet long or a dummy of the same length. The outer diameter of the pipe or dummy shall be not more than 0.5 inches smaller than the inside diameter of that part of the well being tested. The dummy, if used, shall consist of a rigid spindle of at least 6-inch diameter extra heavy pipe with three rings, rigidly fixed to the pipe so that they cannot move longitudinally along the pipe. The rings shall be at least 12 inches in length, truly cylindrical, and shall be placed one at each end of the dummy and with one ring in the center. The rings shall consist of suitable material that will not harm the interior of the casing while being lowered or raised. An example of an approved dummy is shown in the Plans.

B. Plumbness Equipment - The test for plumbness shall be conducted using a digital gyroscopic deviation probe capable of measuring inclination and direction of drift. The output of the survey shall consist of station depth, inclination, azimuth, true vertical depth, departures, and the plane of closure (displacement). Log presentation shall consist of color plots of plan, vertical, and three-dimensional views of the production well casing.

30 Acceptable service companies to perform plumbness testing are listed in Section 3.5.2.E.1 of these Technical Specifications.

3.10.2. Methods
A. Alignment Testing - Alignment shall be tested by lowering into the well to the top of the screened intake portion of the well, a section of pipe 40 feet long or a dummy of the same length.

B. Plumbness Survey - The plumbness of the well shall be determined in 10-foot intervals from the ground surface to the bottom of the well.

3.11. Video Survey

1. After final clean-up of the well and prior to disinfection, and before welding a plate on the top of the casing, the Contractor shall conduct a video survey of the entire casing and screen assembly. The camera shall be in color and have side-scan capability.

The survey shall be witnessed by the Engineer.

If the Engineer determines that any portion of the video survey record is of inadequate quality (e.g., clarity) to allow detailed examination of the inside of the well, the Contractor shall rerun the survey at Contractor’s expense. Clarity should be of sufficient quality to evaluate the integrity of all joints, screen openings, the sounding port, and the entire inside surface of the casing assembly. Logging speed of the video survey shall not exceed 30 feet per minute.

2. The record of the survey shall be recorded and provided to the Engineer in digital form.

3.12. Disinfection of Well
A. Disinfection Preparation - The Contractor shall conduct disinfection after construction of the well and all specified tests and video logging have been completed. The Contractor shall carry out adequate cleaning procedures immediately preceding disinfection where evidence indicates that normal well construction and development work have not adequately cleaned the well. All oil, grease, soil, and other materials that could harbor and protect bacteria from disinfectants shall be removed from the well. Unless prior approval is obtained for employing chemicals or unusual cleaning methods, the cleaning operation is to be carried out by pumping and swabbing only. Where test pumping equipment is to be utilized, such equipment shall be installed prior to or during disinfection and shall be thoroughly hosed, scrubbed or otherwise cleaned of foreign material prior to its installation into the well. The Contractor is responsible for removing or mitigating the effects of all materials introduced into the well during drilling, construction, development, and testing.

B. Interim Disinfection - Should a delay of five days or more be anticipated between the completion of the well and the regularly scheduled well disinfection, an interim disinfection shall be provided by the Contractor. The Contractor shall apply liquid chlorine in an amount equal to 25 percent of the amount required for final disinfection. For this purpose, the disinfection agent shall be furnished or prepared in liquid form and placed in the well through a tremie pipe of sufficient length to extend to the bottom of the well. The disinfection agent shall be applied through the tremie pipe. A volume of water sufficient enough to displace the disinfection agent from the tremie pipe will be added to the tremie pipe. The disinfection agent shall be placed at regular intervals sufficient to achieve a
