15 SECTION CONTRACTOR'S CONSTRUCTION SCHEDULE PART 1 - GENERAL 1.01 SCOPE This section specifies the procedures for preparing the construction schedule used for planning and managing construction activities. The schedule provides a basis for determining the progress status of the project relative to the completion time and specific dates DESCRIPTION The Contractor shall prepare a time scale network schedule using a critical path method. A general guide for preparing such a schedule is contained in The Use of CPM in Construction, a Manual for Contractors, published by the Associated General Contractors of America. The schedule shall depict all significant construction activities and all items of work listed in the breakdown of contract prices submitted by the Contractor in accordance with the bid schedule. The dependencies between activities shall be indicated so that it may be established what effect the progress of any one activity has on the schedule. Detailed network activities shall include, in addition to construction activities, the submittal and approval of samples of material and shop drawings, the procurement of critical materials and equipment, and their installation and testing. All submittals of equipment and materials in Divisions 11, 13, 14, 15 and 16 shall be shown on the schedule together with appropriate allowances for review and delivery times, installation, testing and training as appropriate. All activities of the City and Construction Manager that affect the progress of the work shall be shown. Any omission of work from the schedule required for contract compliance shall not excuse the Contractor from completing such work within any applicable completion date. Completion time shall be shown on the schedule. Activities making up the critical path shall be identified. No activity on the schedule shall have a duration longer than 21 calendar days except activities comprising only fabrication and delivery, which may extend for more than 21 calendar days. Activities which exceed these limits shall be divided into more detailed components. The scheduled duration of each activity shall be based on the work being performed during the normal 40-hour work week with allowances made for legal holidays and normal weather conditions. The Contractor shall not work on legal holidays except by permission of the Construction 10

16 Manager. Legal holidays are defined as the holidays observed by the respective job classifications as defined by the California Department of Industrial Relations, Prevailing Wage Determinations. The Contractor shall notify the Construction Manager by Friday of their intent to work on any immediately following Saturday or Sunday. Delays to project completion experienced during holidays or weekends without proper permission or notice will not be considered to be the responsibility of the City or Construction Manager. Schedules shall be realistic. Contractors shall be required to show use of all calendar days allowed for completion in their schedule or accept a no cost change order reducing the number of days allowed for the completion of the work to the amount shown on the proposed and approved schedule SUBMITTAL PROCEDURES Within 20 days after the date of the Notice of Proceed, the Contractor shall complete a construction schedule conforming to Part 1.02, Description, and representing in detail all planned procurement and onsite construction activities. The schedule shall be prepared on reproducible paper and may be in draft form with legible freehand lines and lettering. The Contractor shall submit the original and three copies to the Construction Manager in accordance with Section 01300, SUBMITTALS. No progress payments shall be made prior to the acceptance of the CPM schedule. Failure to resubmit updated schedules as required herein shall result in an increase in the retentions of the amounts due the Contractor as described in these contract documents. Within 14 calendar days after receipt of the submittal, the Construction Manager shall review the submitted schedule and return two copies of the marked up original to the Contractor. If the Construction Manager finds that the submitted schedule does not comply with specified requirements, the corrective revisions will be noted on the submittal copy returned to the Contractor for corrections and resubmittal as specified in Section 01300, SUBMITTALS SCHEDULE REVISIONS Revisions to the accepted construction schedule may be made only with written approval of the Contractor and the City. Changes in timing for activities which are not on the critical path may be modified with written agreement of the Contractor and Construction Manager. A change affecting the timing of any activity on the critical path, the completion time and specific dates and work sequencing may be made only with the approval of the Construction Manager and the City PROJECT STATUS UPDATE A jobsite meeting will be held each month at a time mutually agreed upon by the Contractor, Construction Manager and City to review the construction progress for compliance with the approved schedule. Weekly meetings will also be held between the Contractor and Construction Manager to review the progress of the work of the previous week and to coordinate the work of the subsequent week. The schedule shall be revised 11

17 whenever: the schedule does not represent the progress of the work; equipment submittals, approvals or deliveries make rescheduling of activities necessary; any change to the sequence of activities occurs or any change occurs to activities on the critical path; or when a contract modification necessitates a revision to the schedule. Updates to the schedule shall, at a minimum, be required on a monthly basis. **END OF SECTION** 12

18 SECTION SUBMITTALS PART 1 - GENERAL 1.01 GENERAL Where required by the specifications, the Contractor shall submit descriptive information which will enable determination of whether the Contractor's proposed materials, equipment, or methods of work are in general conformance to the design concept and in compliance with the drawings and specifications. The information to be submitted shall consist of drawings, specifications, descriptive data, certificates, samples, test results and such other information, all as specifically required in the specifications. In some instances, specified submittal information describes some, but not all, features of the material equipment, or method of work. Features not requiring submittals shall be as specified. Submittal review shall be only for general conformance with the design concept and general compliance with the information given in the contract documents. It shall not include review of quantities, dimensions, weights or gages, fabrication processes, construction safety precautions, all of which are the sole responsibility of the Contractor. Review of a specific item shall not indicate acceptance of an assembly of which the item is a component. The Engineer shall not be required to review, and shall not be responsible for, any deviations from the contract documents not clearly noted by the Contractor, nor shall the Engineer be required to review partial submissions or those for which submissions for correlated items have not been received. The Contractor may authorize material or equipment suppliers to deal directly with the Engineer with regard to such submittals; however, ultimate responsibility for the accuracy and completeness of the information contained in the submittal shall remain with the Contractor CONTRACTOR'S RESPONSIBILITIES The Contractor shall be responsible for the accuracy and completeness of the information contained in each submittal and shall assure that the material, equipment, or method of work shall be described in the submittal. The Contractor shall verify that all features of all products conform to the requirements of the specifications and drawings. The Contractor shall verify that all features of all products conform to the requirements of the specifications and drawings. The Contractor shall insure that there is no conflict with other submittals and shall notify the Engineer in each case where his submittal may affect the work of City or others. The Contractor shall insure coordination of submittals among the related crafts and subcontractors. Immediately following Award of the Contract, the Contractor shall review the plans and specifications and shall prepare a list of all submittals anticipated on the project and shall 13

19 submit this list to the Engineer. Items not on the list but requiring review shall be added to the list as requested by the Engineer at any time during the construction TRANSMITTAL PROCEDURE A. General Submittals regarding material and equipment shall be accompanied by a transmittal form. A separate form shall be used for each specific item, class of material, equipment, and for items specified in separate, discrete sections. Submittals for various items shall be made with a single form when the items taken together constitute a manufacturer's package or are so functionally related that expediency indicates checking or review of the group or package as a whole. A unique number, sequentially assigned, shall be noted on the transmittal form accompanying each item submitted. Submittal numbers shall have the following format: "XXX-YYYYY-ZZ"; where "XXX" is the sequential number assigned by the Contractor, "YYYYY" is the specification section number covered by the submittal, and "ZZ" is the sequential number of the submittal ("01" for the first submittal, "02" for the second submittal, etc.). Resubmittals shall have the same submittal number format; where "XXX" is the originally assigned submittal number. Submittal , for example, would be the second submittal (first resubmittal) of submittal 25 covering Section B. Deviation from Contract If the Contractor proposes to provide material, equipment, or method of work which deviates from the contract documents, he shall so indicate on the transmittal form accompanying the submittal copies. C. Submittal Completeness Submittals which do not contain all the information required to be submitted, including deviations, are not acceptable and will be returned without review. D. Requests for Substitution The Contractor may offer material or equipment of equal or better quality and performance in substitution for those specified. The City will consider offers for substitution only from the Contractor and will not acknowledge or consider such offers from suppliers, distributors, manufacturers, or subcontractors. The Contractor's offers of substitution shall be made in writing to the Engineer and shall include sufficient data to enable the Engineer to assess the acceptability of the material or equipment for the particular application and requirements. If the offered substitution necessitates changes to or coordination with other portions of the work, the data submitted shall include drawings and details showing such changes. 14

20 Contractor agrees to perform these changes as part of the substitution of material or equipment at no additional cost to City. Within 21 calendar days after receipt of the offer of substitution, the Engineer will review the material submitted by the Contractor and advise the Contractor of objections, if any, to the proposed substitution or if further information is required. Upon notification by the Engineer, the Contractor shall either provide material or equipment which complies with project specifications or furnish requested additional information. While the Engineer might not take any objections to the proposed substitution, such action shall not relieve the Contractor from responsibility for the efficiency, sufficiency, quality and performance of the substitute material or equipment, in the same manner and degree as the material and equipment specified by name. Any cost differential associated with a substitution shall be reflected in the offer and the contract documents shall be modified by a change order REVIEW PROCEDURE When the contract documents require a submittal, the Contractor shall submit copies of the specified information as follows unless otherwise specified: A. One reproducible original of all the submitted information. When individual sheets in the submittal exceed 8 1/2" x 11", a sepia shall be submitted. B. Five copies of all the submitted information. C. Submittals shall be delivered or mailed to: The Construction Manager (To be determined) Unless otherwise specified, within 21 calendar days after receipt of the submittal, the submittal will be reviewed and three copies of the marked-up reproducible original will be returned to the Contractor. The reproducible original shall be retained by the Engineer. The returned submittal shall indicate one of the following actions: A. If the review indicates that the material, equipment, or work method is in general conformance with the design concept and complies with the drawings and specifications, submittal copies will be marked "NO EXCEPTIONS TAKEN." In this event, the Contractor may begin to implement the work method or incorporate the material or equipment covered by the submittal. B. If the review indicates limited corrections are required, copies will be marked "MAKE CORRECTIONS NOTED." The Contractor may begin implementing the work method or incorporating the material and equipment covered by the submittal in accordance with the noted corrections. Where submittal information will be incorporated in operation and maintenance information, a corrected copy shall be provided. C. If the review reveals that the submittal is insufficient or contains incorrect data, copies will be marked "REVISE AND RESUBMIT." Except at his own risk, the Contractor shall not undertake work covered by this submittal until it has been revised, resubmitted and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS 15

21 NOTED." D. If the review indicates that the material, equipment, or work method is not in general conformance with the design concept or in compliance with the drawings and specifications, copies of the submittal will be marked "REJECTED". Submittals with deviations which have not been identified clearly may be rejected. Except at his own risk, the Contractor shall not undertake the work covered by such submittals until a new submittal is made and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED". Following the initial review, two "resubmittals" will be allowed by the Engineer prior to a "backcharge" for engineering review and administration costs being incurred by the Contractor. The "backcharge" will be deducted from any amounts due the Contractor EFFECT OF REVIEW OF CONTRACTOR'S SUBMITTALS Review of drawings, methods of work, or information regarding materials or equipment the Contractor proposes to provide shall not relieve the Contractor of his responsibility for errors therein and shall not be regarded as an assumption of risks or liability by the City, or by any officer or employee thereof, or by any engineering firm conducting such review on behalf of the City, and the Contractor shall have no claim under the contract on account of the failure, or partial failure, of the method of work, material, or equipment so reviewed. A mark of "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED" shall mean that the City has no objection to the Contractor, upon his own responsibility, using the plan or method of work proposed, or providing the materials or equipment proposed. **END OF SECTION** 16

22 SECTION SCHEDULE OF VALUES PART 1 - GENERAL 1.1 WORK OF THIS SECTION A. The CONTRACTOR shall develop and submit a Schedule of Values (lump sum price breakdown) to be incorporated into the cost loading function of the Construction Schedule as specified in Section Monthly progress payment amounts shall be determined from the monthly progress updates of the Construction Schedule activities. The Schedule of Values shall be developed independent of, but simultaneous with the development of the Construction Schedule activities and logic as follows: 1.2 RELATED SECTIONS A. The WORK of the following Sections apply to WORK of this Section. Other Sections of the Specifications, not referenced below, shall also apply to the extent required for proper performance of the WORK. 1. Section 01025, Measurement and Payment 2. Section 01200, Project Meetings 3. Section 01300, Submittals 4. Section 01310, Construction Schedules 1.3 SUBMITTALS A. Preliminary Schedule of Values. B. Detailed Schedule of Values. 17

23 PART 2 - PRODUCTS 2.1 PRELIMINARY SCHEDULE OF VALUES A. The CONTRACTOR shall submit a preliminary Schedule of Values for the major components of the WORK at the Preconstruction Conference. The listing shall include a detailed breakdown of cost for each lump sum bid item specified in Section 01025, MEASUREMENT AND PAYMENT. The CONTRACTOR and CONSTRUCTION MANAGER shall meet and jointly review the preliminary Schedule of Values, and make any adjustments in value allocations if, in the opinion of the CONSTRUCTION MANAGER, these are necessary to establish fair and reasonable allocation of values for the major components of the WORK. Front end loading of the Schedule of Values will not be permitted. The CONSTRUCTION MANAGER may require reallocation of major WORK components from items in the above listing if such reallocation is necessary in the opinion of the CONSTRUCTION MANAGER. 2.2 DETAILED SCHEDULE OF VALUES A. The CONTRACTOR shall prepare and submit a detailed Schedule of Values to the CONSTRUCTION MANAGER within 15-days from acceptance of preliminary schedule of values that is submitted within 15-days of NTP per 3.1 A this section. The detailed Schedule of Values shall be based on the accepted preliminary Schedule of Values for major components of the WORK. Sufficient breakdown of the construction activities shall be provided to allow development of a detailed Schedule of Values sufficient to determine appropriate monthly progress payment amounts through cost loading of the Construction Schedule activities. The CONSTRUCTION MANAGER shall determine the acceptable numbers, details and description of values established. If, in the opinion of the CONSTRUCTION MANAGER, a greater number of items or construction activities than those proposed by the CONTRACTOR are necessary, the CONTRACTOR shall add the additional items so identified by the CONSTRUCTION MANAGER. 1. The minimum detail of breakdown of the major components of the WORK is indicated in Part 1 of Section Measurement and Payment. Greater detail shall be provided as directed by the CONSTRUCTION MANAGER. a. All other WORK not specifically included in the above items shall be detailed as necessary for establishment of cost and Construction Schedule activity items. The CONTRACTOR and CONSTRUCTION MANAGER shall meet and jointly review the detailed Schedule of Values within 35-days from the date of Notice to Proceed. The value allocations and extent of detail shall be reviewed to determine any necessary adjustments to the values and to determine if sufficient detail has been proposed to provide cost loading of the Construction Schedule activities. 18

24 2. Following acceptance of the detailed Schedule of Values, the CONTRACTOR shall incorporate the values into the cost loading portion of the Construction Schedule. The Construction Schedule activities and logic shall have been developed concurrent with development of the detailed Schedule of Values; however, it shall be necessary to adjust the detailed Schedule of Values to correlate to individual Construction Schedule activities. Because of the independent but simultaneous development of the Schedule of Values and the Construction Schedule activities, it is anticipated that instances will occur where interfacing these two documents will require changes to both documents. Construction Schedule activities may need to be added to accommodate the detail of the Schedule of Values. Schedule of Value items may need to be added to accommodate the details of the Construction Schedule activities. Where such instances arise, the CONTRACTOR shall propose changes to the Schedule of Values and to the Construction Schedule activities acceptable to the CONSTRUCTION MANAGER to satisfy the Construction Schedule cost loading requirements. 2.3 CROSS REFERENCE LISTING A. To assist in the correlation of the Schedule of Values and the Construction Schedule, the CONTRACTOR shall provide a Cross Reference Listing which shall be furnished in two parts. The first part shall list each Scheduled Activity with the breakdown of the respective valued items making up the total cost of the activity. The second part shall list the valued item with the respective Scheduled Activity or Activities that make up the total cost indicated.
