d. Schedules shall show Contract completion of the Work on the Contract completion date and with zero or positive total float even if the Contractor plans to finish early. In no event shall acceptance of the schedule be a basis for a claim for delay against Agency or Engineer by Contractor for an early finish. A Progress Schedule containing activities with negative float or that extend beyond the Contract completion date will not be acceptable. e. Acceptance of the Progress Schedule by Engineer does not relieve Contractor of responsibility for accomplishing the Work by the Contract completion date. Omissions and errors in the accepted Progress Schedule shall not relieve the Contractor of obligations under the Contract. Acceptance by Engineer in no way makes Engineer or
01 33 00 CONSTRUCTION PROGRESS SCHEDULE Date Printed: June 3, 2024 Document Version: 1.0 Current Update: May 2023
Agency an ensurer of the Schedule's success or liable for time or cost overruns. Engineer and Agency disclaim any obligation or liability by reason of acceptance of the Progress Schedule by the Engineer.
1.13 RESPONSIBILITY OF SCHEDULE COMPLIANCE
a. Whenever it becomes apparent from the current Progress Schedule that the Critical Path is delayed and the Contract completion date will not be met, Contractor shall mitigate the delay by taking some or all of the following actions at no additional cost to Agency.
1. Increase construction labor force in such quantities and crafts as will bring the Project back on schedule within the completion dates and milestones.
2. Increase the number of working hours per shift, shifts per day, Working Days per week, and the amount of construction equipment, or any combination of the foregoing, to substantially eliminate the backlog of Work.
3. Re-schedule activities to achieve maximum practical concurrence of activities and to comply with the schedule date(s).
b. Within 10 Calendar Days of the Engineer’s request, Contractor shall submit a recovery schedule and written statement of the steps intended to remove or arrest the delay to the Critical Path in the schedule. If the Contractor fails to submit the required information or should fail to take measures acceptable to the Engineer, the Engineer with Agency concurrence may direct Contractor to increase labor force , equipment and scheduled Work hours to remove or arrest the delay to the Critical Path and the Contractor shall promptly provide such level of effort at no additional cost to Agency. c. In the event Contractor fails to follow the updated or revised recovery schedule, Agency may elect to withhold progress payments until Contractor complies with the revised schedule.
d. Should Contractor’s efforts not remove or arrest the delay to the Critical Path of the accepted schedule, then Agency shall be entitled to supplement Contractor’s workforce and equipment to remove and arrest any delay, and shall be entitled to deduct all costs and expenses associated with the supplemental workforce and equipment from payments due to the Contractor. If insufficient Contract funds remain, Agency may recover such funds from Contractor and its Surety.
1.14 CHANGE ORDERS, DELAYS, AND EXTENSIONS OF TIME
a. When Change Orders or delays are experienced by Contractor and Contractor requests an extension of time, Contractor shall submit a written time impact analysis to the Engineer illustrating the influence of each change or delay to the current Contract Schedule completion date. Each time impact analysis shall include a fragment incorporating the Change Order or delay into the Progress Schedule to demonstrate how Contractor was delayed.
b. Each time impact analysis shall demonstrate the estimated time impact based on the events of the change or the delay; the date the change was given to Contractor or the delay incurred, the status of construction at that point in time, and the event time
01 33 00 CONSTRUCTION PROGRESS SCHEDULE Date Printed: June 3, 2024 Document Version: 1.0 Current Update: May 2023
computation of all activities affected by the change or delay. The event times used in the analysis shall be those included in the latest update of the Progress Schedule or as adjusted for the events of delay.
c. An electronic copy shall be submitted within 7 Calendar Days of delay occurrence or direction to proceed with a change is given to Contractor. No time extensions will be considered if the time impact analysis is not submitted within the specified time. d. The Engineer will review Contractor’s time impact analysis. Contractor shall furnish such justification and supporting evidence as the Engineer deems necessary to determine whether Contractor is entitled to an extension of time. Engineer’s review of each time impact analysis will be made within 5 Working Days of receipt of the time impact analysis and additional information as required by the Engineer, unless subsequent meetings and negotiations are necessary.
e. The Contract completion time will be adjusted only for causes specified in paragraph 15.
Time extensions will be granted only to the extent that equitable time adjustments for the activity or activities affected exceed the total or remaining float along the Critical Path at the time of actual delay. Delays in activities which are not on the Critical Path and do not affect Contract completion dates, will not be considered for an extension of time.
1.15 CAUSES FOR EXTENSIONS OF TIME
a. Additional positive total float in the Progress Schedule generated by efficiencies of Agency or Contractor is a shared commodity to be reasonably used by either party, and belongs exclusively to the Project. The Contractor is not entitled to any additional compensation for completion of the Project prior to expiration of the Contract Times. b. Agency-Initiated Changes. Agency initiated changes to the Contract Work that absorb float time will not be considered for an extension of time. Agency-initiated changes that affect the Critical Path of the Progress Schedule shall be grounds for extending or shortening completion dates. Use of float time for Contractor initiated changes will require Agency’s concurrence. Contractor’s changes, however, shall give way to Agency- initiated changes competing for the same float time.
c. Outside Contractor’s Control. Events outside of the Contractor’s control that affect the Critical Path of the Progress Schedule will be considered for an extension or reduction of the Contract Times.
d. Weather Delays. Engineer will obtain weather data during construction from a reputable source and will maintain weather records.
1. Engineer will determine Contractor’s entitlement to an extension of the Contract Time as a result of weather delays. Extensions of time will be granted at the discretion of the Engineer for circumstances not covered by the flow chart.
2. Any weather -related extension of Contract Time shall be non- compensable.
Efficiencies gained as a result of favorable weather within a calendar month, where the number of days of normally anticipated weather days is less than
01 33 00 CONSTRUCTION PROGRESS SCHEDULE Date Printed: June 3, 2024 Document Version: 1.0 Current Update: May 2023
expected, shall contribute to the Project float and shall not affect the Contract Times.
3. Application for a weather- related extension of time shall be submitted to the Engineer, and shall state the extension requested and be supported by the relevant weather data.
1.16 AS-BUILT SCHEDULE
a. As a condition precedent to release of final payment, the last update to the Progress Schedule submitted shall be identified by the Contractor as the “As -Built Schedule.” The “As-Built Schedule” shall reflect the exact manner in which the Project was actually constructed (including actual start and completion dates, activities, sequences, and logic) and shall be signed and certified by the Contractor’s Project manager.
1.17 SCHEDULE SOFTWARE SETTINGS AND RESTRICTIONS
a. Contractor shall consult with Engineer for acceptable Primavera Project Manager software settings and restrictions. The following shall apply unless otherwise directed by the Engineer.

A. Water Pollution Prevention. The Contractor shall plan for and implement temporary construction BMPs to mitigate the water quality impacts of land disturbance and non- storm water discharges related to construction activities in accordance the Agency’s current Municipal Stormwater Permit and Carlsbad Municipal Code Chapter 15.12. BMPs are the schedules of activities, prohibitions of practices, maintenance procedures and other management practices employed during construction activities to prevent or
01 50 00 TEMPORARY FACILITIES AND CONTROLS Date Printed: June 3, 2024 Document Version: 1.0 Current Update: May 2023
reduce pollution of bodies of water protected by the federal Clean Water Act (33 U.S.C. § 1251 et seq. ) and the state Porter -Cologne Water Quality Control Act (Water Code , § 13000 et seq.), which include oceans, lagoons, lakes, streams and other sensitive water bodies and water courses. Construction BMPs also include physical devices and structural construction control measures designed to prevent soil erosion from occurring on the Work Site, or that are designed to prevent sediment from leaving the Work S ite, both of which are referred to hereafter as “Water Pollution .” BMPs are also intended to protect the health, safety and welfare of the public and to prevent damage to adjoining public and private property resulting from construction activities.
B. Pollution prevention practices and the minimum BMPs are required during all 12 months of the year. BMPs and other erosion control practices must be implemented as the most important “first line of defense .” The Agency has adopted the CASQA ‘Stormwater Best Management Practices Handbook: Construction ,’ latest edition, as its preferred source for adopting construction BMPs. All BMPs must correspond to the BMP Fact Sheets included in the CASQA Construction Handbook. With the approval of the Engineer, or designee, the Agency may accept comparable BMPs fro m reputable alternative sources.
As used in this section, “Engineer” shall have the same meaning as “Construction Manager.”
C. The Contractor shall utilize the Agency’s Tier 1 or Tier 2 SWPPP templates and include all applicable elements provided in the template. The SWPPP templates are available on the Agency’s website at [PROJECT ENGINEER insert website address here]. Tier 1 and Tier 2 SWPPP templates include standard storm water prevention construction notes, a Project information block, a Storm Water Compliance Statement, Agency approval block and a BMP Checklist Table. The BMP Checklist Table is intended to help the Contractor select appropriate BMPs best suited to the Project and the Work. Additionally, the SWPPP shall include a Site plan showing the proposed Project Site and depicting the areas of proposed construction and proposed locations of construction BMPs. The Tier 1 and Tier 2 SWPPP plans shall be submitted as additional sheets to the construction plan set.
D. The Engineer may require Contractor to adopt additional BMPs if the Engineer determines the selected BMP(s) are ineffective or incapable of preventing Water Pollution from escaping the Work site. Tier 1 and Tier 2 SWPPPs must be combined with proper and timely installation of the BMPs, thorough and frequent inspections, maintenance, and documentation. The Contractor shall ensure that the selected BMPs are appropriately incorporated into the Site design and, if required by the Engineer, must employ a qualified professional to ensure proper installation and maintenance of the BMPs.
E. The Engineer may suspend the Work, consistent with Supplemental General Provisions Section 6 -6, at the Contractor’s cost, that create Water Pollution or otherwise violate water quality standards required by the federal Clean Water Act (33 U.S.C. § 1251 et seq.) and the state Porter-Cologne Water Quality Control Act (Water Code , § 13000 et seq.) if the Engineer determines that the Contractor has failed to satisfy all requirements of this section. If the Contractor violates any provisions of this subsection, or if Water Pollution
01 50 00 TEMPORARY FACILITIES AND CONTROLS Date Printed: June 3, 2024 Document Version: 1.0 Current Update: May 2023
occurs in the Work S ite for any reason, the Contractor shall immediately notify the Engineer.
