SCHEDULING OF WORK
PART 1 GENERAL

1.1 GENERAL
A. The scheduling of the work under the Contract shall be performed in accordance with the requirements of this Section.

B. The development of the schedule, the cost loading of the schedule, monthly payment requisitions and project status reporting requirements of the Contract shall employ computerized Critical Path Method (CPM) or bar chart scheduling.

1.2 DEFINITIONS AND REQUIREMENTS
A. Critical Path Method (CPM): CPM, as required by this Section, shall be interpreted to be generally as outlined in the Association of General Contractors (AGC) publication, "The Use of CPM in Construction." except that either "i-j" arrow diagrams or precedence diagramming format may be utilized. In the case of conflicts between this specification and the AGC Document, this specification shall govern.

B. Construction Schedules: Construction schedules shall include a graphic network diagram and computerized construction schedule reports.

C. Networks: The CPM network shall be in a form of a time scaled "i-j" activity-on-arrow or precedence type diagram and may be divided into a number of separate sheets with suitable match lines relating the interface points among the sheets.

1. Individual sheets shall not exceed 36-inch by 60-inch.

D. All construction activities and procurement shall be indicated in a time-scaled format and a calendar timeline shall be shown along the entire sheet length.

1. Each activity arrow or node shall be plotted so that the beginning and completion dates of each activity are accurately represented along the calendar timeline.

2. All activities shall be shown using the symbols that clearly distinguish between critical path activities, non-critical activities and free float for each non-critical activity.

3. All activity items shall be identified by their respective Activity Number, Responsibility Code, Work Duration, and their Dollar Value.

4. All non-critical path activities shall show their total float time in scale form by utilizing a dotted line or some other graphical means.

E. Duration Estimates: The duration estimate indicated for each activity shall be computed in calendar days and shall represent the single best estimate considering the scope of the activity work and resources planned for the activity. Except for certain non-labor activities, such as curing of concrete or delivery of materials, activity duration

E. Calaveras Blvd & Yosemite Dr. Water Valves July 2024 Replacement Project No. 7118 & 7100 -2- 01 32 13
shall not exceed 10 calendar days nor be less than one calendar day unless otherwise accepted by the Cityís Representative.

F. Float Time: Float time shall be as follows:

1. Definition: Unless otherwise provided herein, float as referenced in these documents, is total float. Total float is the period of time measured by the number of calendar days each non-critical path activity may be delayed before it and its succeeding activities become part of the critical path. If a non-critical path activity is delayed beyond its float period, that activity then becomes part of the critical path and controls the end date of the project. Thus, the delay of the non-critical path activity beyond its float period will cause delay to the project itself.

2. Float Ownership: Neither the City nor the Contractor owns the float time. The project owns the float time. As such, liability for delay of the project completion date rests with the party actually causing delay to the project completion date.

For example, if Party A uses some, but not all of the float time and Party B later uses the remainder of the float time as well as additional time beyond the float time, Party B shall be liable for the costs associated with the time that represents a delay to the project's completion date. Party A would not be responsible for any costs since it did not consume all of the float time and additional float time remained, therefore, the project's completion date was unaffected.

1.3 SUBMITTALS
A. Submit schedules per requirements of Specification Section 01 33 00 ñ Submittal Procedures.

B. Estimated Schedule

1. The Contractor shall submit an Estimated schedule document within 21 days after the issuance of the Notice of Award.

C. Schedule Updates

1. Submit monthly when requested to do so by the Engineer to reflect changes to Estimated schedule.

1.4 CONSTRUCTION SCHEDULE
A. The schedule shall indicate the major components of the project work and the sequence relations between major components and subdivisions of major components.

B. The schedule shall be cost loaded based on the schedule of values as approved by the Cityís Representative.

C. Sufficient detail shall be included for the identification of subdivisions of major components into such activities as:

1. All work tasks requiring a partial closure of existing facilities and roadways.

E. Calaveras Blvd & Yosemite Dr. Water Valves July 2024 Replacement Project No. 7118 & 7100 -3- 01 32 13

2. Trenching and backfilling.

3. Piping

4. Finished pavement.

5. Site work.

6. Other important work within the overall project scope.

D. Planned durations and start dates shall be indicated for each work item subdivision.

Each major component and subdivision component shall be accurately plotted on time scale sheets not to exceed 36-inch by 60-inch in size. Not more than one sheet shall be employed to represent this information.

1.5 SCHEDULE REVIEW
A. The Cityís Representative and the Contractor shall meet to review and discuss the estimated schedule after it has been submitted to the Cityís Representative.

1. The Cityís Representative's review and comment on the schedules shall be limited to Contract conformance with the sequencing and milestone requirements as stated in other sections of the specifications.

2. The Contractor shall make corrections to the schedules necessary to comply with the Contract requirements and shall adjust the schedules to incorporate any missing information requested by the Cityís Representative.

1.6 ACCEPTANCE
A. The acceptance of the Contractor's schedule by the Cityís Representative and City will be based solely upon the schedule's compliance with the Contract requirements.

B. By way of the Contractor assigning activity durations and proposing the sequence of the Work, the Contractor agrees to utilize sufficient and necessary management and other resources to perform the work in accordance with the schedule.

C. Upon submittal of a schedule update, the updated schedule shall be considered the "current" project schedule.

D. Submission of the Contractor's progress schedule to the City or Cityís Representative shall not relieve the Contractor of the Contractor's total responsibility for scheduling, sequencing, and pursuing the Work to comply with the requirements of the Contract Documents, including adverse effects such as delays resulting from ill-timed work.

1.7 MONTHLY UPDATES AND PERIODIC SCHEDULE SUBMITTALS
A. Following the acceptance of the Contractor's Estimated Construction Schedule, the Contractor shall monitor the progress of the Work and adjust the schedule each month to reflect actual progress and any changes in planned future activities.

1. Each schedule update submitted must be complete including all information requested in the estimated schedule submittal.

E. Calaveras Blvd & Yosemite Dr. Water Valves July 2024 Replacement Project No. 7118 & 7100 -4- 01 32 13

2. Each update shall continue to show all work activities including those already completed.

3. These completed activities shall accurately reflect the "as built" information by indicating when the work was actually started and completed.

B. Neither the submission nor the updating of the Contractor's estimated schedule submittal nor the submission, updating, change or revision of any other report, curve, schedule or narrative submitted to the Cityís Representative by the Contractor under this Contract, nor the Cityís Representative's review or acceptance of any such report, curve, schedule or narrative shall have the effect of amending or modifying, in any way, the Contract completion date or milestone dates or of modifying or limiting, in any way, the Contractor's obligations under this Contract. Only a signed, fully executed change order can modify these contractual obligations.

C. The monthly schedule update submittal will be reviewed with the Contractor during a construction progress meeting held on a month end date to be determined. The goal of these meetings is to enable the Contractor and the Cityís Representative to initiate appropriate remedial action to minimize any known or foreseen delay in completion of the Work and to determine the amount of Work completed since the last month's schedule update.

1. The status of the Work will be determined by the percent complete of each activity shown in the Network Diagram.
