If not identified as a bid item, mobilization, ov erhead, bond, insurance, other general costs and profit shall be prorated to each item so that the total of the prices for all items equal the lump sum price. At the discretion of the Construction Manager, mobilization, bond and insurance costs may be provided for separately if accompanied by invoices to verify actual expenses.
The price breakdown shall be generally in the same format as the Contract specifications divisions and subdivisions, with major items of work listed individually. The price breakdown shall be by structure, civil, landscaping, or other logical division of work. The price breakdown for architectural, structural, mechanical, and electrical work shall include separate items for identifiable portions of the structures. The price breakdown shall include separate allowances for any testing and startup work required. Measurable approximate quantities of work performed by the Contractor or its subcontractors shall be provided. For quantities that are the sum total of several individual quantities, backup summaries shall be provided which list the individual descriptions and quantities.

For the work performed, payment will be made for the documented actual cost of the following:
a. Direct labor cost for workers, including foremen, who are directly assigned to the force account work: Direct labor cost is the act ual payroll cost, including wages and fringe benefits as established by negotiated labor agre ements or state prevailing wages. To the actual payroll cost will be added a labor surcharge which shall be the actual costs of taxes and insurance.

Submittals
01300-3
5. Delivery: Deliver submittals to Construction Mananger via [email protected].
6. Incomplete Submittals, including those not correctly transmitted, not correctly titled and identified, or not bearing the Contractor's review and approval stamp, shall be returned to the Contractor without review.
7. Interrelated Submittals Except where the preparation of a submittal is dependent upon the approval of a prior submittal, simultaneously submit all submittals pertaining to the same class or portion of the Work.
During the preparation of submittals, inform al communication and clarifications may be required between the Contractor and the City for exchange of technical information to assist and expedite preparation of complete su bmittals. As a result of this informal information exchange, certain minor refinement s and revisions in the systems specified may be authorized informally by the City, but these shall not alter the scope of work or case increase or decrease in the Contract price. During this informal exchange, no oral statement by the City shall be construed to give formal approval of any component or method, nor shall any statement be construed to grant formal exception to, or variation from these Specifications.
F. Contractor's Review and Approval All submitta ls shall be submitted as the instruments of the Contractor, who shall be responsible for their accuracy and completeness and coordination.
Such responsibility shall not be delegated in whol e or part to subcontr actors or suppliers.
These submittals may be prepared by the Contra ctor, subcontractors, or suppliers, but the Contractor shall ascertain that submittals meet all of the requirements of the Contract Documents. The Contractor shall ensure that there is no conflict with other submittals and notify the Construction Manager in each case wh ere its submittal may affect the work of another contractor or the City. The Contractor shall ensure coordination of submittals among the related crafts and subcontractors.
On every submittal of shop drawings, sample s, materials lists, equipment data, instruction manuals, and other submittals upon which the proper execution of the Work is dependent, mark with the Contractor's review and approv al stamp certifying that (1) the submittal has been reviewed, checked, and approved and the contents have been coordinated with the requirements of the Work and the Technical Specifications and Project Plans including related Work, (2) all quantities, field measurements, field construction criteria, materials, equipment, catalog numbers, and similar data have been determined and verified, or that it shall be done, and (3) the Work covered by the submittal is recommended by the Contractor and the Contractor's guarantee shall fully apply thereto. The Contractor's stamp shall be dated and signed by the Contractor in every case.
G. Review and Approval Submittals will be reviewed only for conformance with the design concept of the Project and with the information given in the Technical Specifications and Project Plans. The approval of a separate item as such shall not indicate approval of the assembly in which the item functions nor shall approval be construed as revising, in any way, the requirements for a fully integrated and operabl e system as specified. The approval of submittals shall not relieve the Contractor of responsibilit y for any deviation from the requirements of the Technical Specifications and Project Plans or for any revision in re- submittals unless the Contractor has given notice in writing of the deviation or revision at the time of submission or resubmission and wri tten approval has been given to the specific deviation or revision. The approval of submi ttals shall not relieve the Contractor of EXHIBIT 2
352
Submittals
01300-4
responsibility for errors or omissions in the submittals or for the accuracy of dimensions and quantities, the adequacy of connections, and t he proper and acceptable fitting, execution, and completion of the Work.
H. Form of Approval Review of submittals has as its primary objective the completion for the City of a project in full conformance with the Contract Plans and Specifications, unmarred by field corrections, and within the time provided. In addition to this primary objective, submittal review as a secondary objective will assist th e Contractor in its procurement of equipment that will meet all requirements of the project Pl ans and Specifications, will fit the structures detailed on the Plans, will be completed with respect to piping, electrical, and control connections, will have the proper functional characteristics, and will become an integral part of a complete operating facility.
After review by the Design Consultant of each of the Contractor’s submissions, the material will be returned to the Contractor with actions defined as follows:
1. NO EXCEPTIONS NOTED (RESUBMITTAL NOT REQUIRED) - Accepted subject to its compatibility with future submissions and additional partial submissions for portions of the work not covered in this submission. Does not constitute approval or deletion of specified or required items not shown in the partial submission.
2. MAKE CORRECTIONS NOTED (RESUBMI TTAL NOT REQUIRED) - Same as 1, except that minor corrections as noted shall be made by the Contractor.
3. AMEND AND RESUBMIT- Rejected because of major inconsistencies or errors which shall be resolved or corrected by the Cont ractor prior to subsequent review by the Design Consultant.
4. NOT ACCEPTABLE (RESUBMIT) - Submitted material does not conform to Plans and Specifications in major respect (i.e., wrong size, model, capacity, or material).
Items 1 and 2 above (no re-submittal required) ar e considered “favorable review.” Items 3 and 4 above (correction and re-submittal required) are considered “unfavorable review.” It shall be the Contractor’s responsibility to copy and/or conform reviewed submittals in sufficient numbers for its files, subcontractors, and vendors.
I. Corrections and Re-submittals Make all required corrections and resubmit the required number of corrected submittals until approved by t he Owner. Direct specific attention in writing to revisions other than the corrections called for by the Owner on previous submittals, and state in writing all variations in costs and your assumption of the cost of related changes the same as is required for deviations in 2.0B. Identify each re-submittal with number of the original submittal followed by consecutive letters starting with "A" for first re-submittal, "B" for second re-submittal, etc. The Owner reserves the right to deduct moneys from the amounts due the Contractor to cover the cost of its review time for any and all submittals beyond the second submission.
J. Check of Returned Submittals Check retur ned submittals for correction and ascertain if the corrections result in extra cost above that included under the Technical Specifications and Project Plans, and give written notice to the Owner within five days if, in your opinion, such extra cost results from corrections. By failing to so notify the Owner or by starting any Work EXHIBIT 2
353
Submittals
01300-5
covered by a submittal, all claims for extra costs resulting from required corrections are waived.
K. Conformance Do not purchase, fabricate, deliver, construct, or commence any Work represented by required submittals until the applicable submittal has been approved.
Conform Work to the approved submittals and all other requirements of the Technical Specifications and Project Plans unless subseq uently revised by contract change order, in which case prepare and submit revised submittals as may be required. Do not proceed with any related Work which may be affected by the Work covered under submittals until the applicable submittals have been approved, particularly where piping, machinery, equipment, concrete work and the required arrangements, embedments and clearances are involved.
L. Piecemeal Submittals Except for reinforcing steel submittals, piecemeal submittals shall be returned un-reviewed. However, for mechanical equipment and the like, separate submittals for embedded items, embedded metal work and anchors shall be reviewed.
3.0 SCHEDULE OF VALUES
Submit to the Owner for acceptance, in the form directed by or acceptable to the Owner, a complete schedule of the values of the various portions of the Work to coincide with the construction schedule, including quantities and unit prices aggregating the Contract Price (except in cases and to the extent that accepted unit prices form the basis for payment). In the schedule, subdivide the Work into component parts in sufficient detail to serve as the basis for progress payments during construction and to coordinate with the progress schedule required for this Work. Provide support data to substantiate its correctness as required by the Owner. Include with each item in the schedule of values, its proper share of overhead and profit. An unbalanced breakdown providing for overpayment to the Contractor on items of Work which would be performed first will not be approved. The schedule of values, when accepted by the Owner, shall be used only as a basis for the Contractor's applications for payment and not for additions to or deductions from the Contract Price. Provide the initial submittal for the schedule of values at the preconstruction conference as per Section 01200.

3.3 Schedule Revisions
The conditions under which the Construction Manager will require revisions of the Construction Schedule include the following:
a. When delay in completion of any work item or sequence of work items results in an estimated extension of project completion by either twenty (20) working days or by five percent (5%) of the remaining duration of time to complete the Contract, whichever is less.
b. When delays in submittals or deliveries make re-planning or rescheduling of the work necessary.
c. When the schedule does not represent ac tual prosecution and progress of the work.
d. 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.

The Contractor shall not make any changes to the critical path without the Construction Manager’s written consent.
4.0 TIME IMPACT ANALYSES
4.1 Requirement
When change orders impacting project duration 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.
4.1.1 Construction Schedule Analysis -
a. Each Time Impact Analysis shall include an analysis demonstrating how the Contractor proposes to incorporate the change order, delay, or Contractor request into the Schedule.
b. The analysis shall demonstrate the time im pact 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.
EXHIBIT 2
372
Progress Schedule
01310-5
4.2 Delays
Activity time delays will not automatically mean that an extension of Contract Time is warranted or due the Contractor.
a. It is possible that a strike or contract modifi cation 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.
b. The Contractor acknowledges and agrees that mitigation for delays due to changes, differing site conditions, and other causes will require revision of preferential sequences of the Work before proposing an updated schedule which supports 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 Co ntractor chooses not to implement the revisions, the Contractor will be entitled to a time extension but is not entitled to compensation for indirect overhead.
c. Float or slack shall not be for the exclusive us e 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.
d. The definitions of "non-critical activities " and "total float" shall be as provided in the Associated General Contractors of America book "CPM in Construction, A Manual for General Contractors."
4.3 Submittal
Time Impact Analyses shall be submitted in quadruplicate 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 mutual agreement by both parties, sc hedule revisions illustrating the influence of change orders, delays, and/or Contractor requests will be incorporated into the next schedule update.
5.0 WEEKLY ACTIVITIES PLAN
On the last working day of every week the Contractor shall submit to the Construction Manager the Contractor's Plan of Activities for the follo wing three weeks. The Plan of Activities shall describe the activity and location of the activity and include the activity's I-J or Activity number as provided in the Construction Schedule.
