SECTION 01310

PROGRESS SCHEDULES

PART 1 – GENERAL

1.01 The Contractor shall prepare and submit Progress Schedules and schedules for submittals in accordance with Article VI of the General Conditions.

1.02 Construction under this Contract must be coordinated with the

OWNER’s personnel and accomplished in a logical order to maintain existing facilities and to allow construction to be completed within the time allowed by Contract Documents.

1.03 The Contractor shall be responsible for developing its own schedule logic with specified durations, manpower and cost data, however all information must be acceptable and compatible with the OWNER’s Master Schedule, and all target, completion and milestone dates generated, must be acceptable to the OWNER.

1.04 CONSTRUCTION SCHEDULING GENERAL PROVISIONS

A. No work shall be done between 7:00pm and 7:00am nor on Sundays or legal holidays without the written permission of the OWNER.

However, emergency work may be done without prior permission.

However, the OWNER shall be notified immediately of all emergency work performed.

B. Night work may be established by the Contractor as regular procedure with the written permission of the OWNER. Such permission, however, may be revoked at any time by the OWNER if the CONTRACTOR fails to maintain adequate equipment and supervision for the proper execution and control of the work at night.

C. Due to potential health hazards and requirements of the State of Florida and the U.S. Environmental Protection Agency, the existing facilities must be maintained in operation.

D. The Contractor shall be fully responsible for providing all temporary piping, plumbing, electrical hook-ups, power supply, heating, ventilating, air conditioning, lighting, temporary structure, or whatever is required to maintain the existing operations. All details of temporary piping and temporary construction are not necessarily shown on the Drawings or covered in the Specifications. However, this does not relieve the Contractor of the responsibility to insure that construction will not interrupt proper, collection and pumping.

ITB No.: 26-403/DL 01310 - 2

E. The Contractor shall have the capability of preparing and utilizing the specified CPM scheduling technique. A statement of CPM capability shall be submitted in writing to the OWNER within ten (10) calendar days of Notice of Award of the Contract and will verify that either the Contractor’s organization has “in-house capability” qualified to use the technique or that the Contractor employs a consultant who is so qualified.

“Capability” shall be verified by description of the construction projects to which the Contractor or his consultant has successfully applied the CPM scheduling technique which shall include at least two (2) projects valued at least half the bid price of this project and at least one (1) project which was controlled throughout the duration of the project by means of systematic use and updating of a computer-based CPM schedule.

The submittal shall include the name of the individual on the Contractor’s staff who will be responsible for the CPM Schedule and for providing the required updating information.

1.05 PROGRESS OF THE WORK

The work shall be executed with such progress as may be required to prevent any delay to the general completion of the work. The work shall be executed at such times and in or on such parts of the project, and with such forces, materials and equipment to assure completion of the work in the time established by the Contract.

PART 2 – PROGRESS SCHEDULE SUBMITTALS

2.01 GENERAL REQUIREMENTS

A. The Contractor shall submit a critical path and cost loaded schedule as described herein.

B. The critical path schedule requirement will consist of base and status progress schedules, monthly progress status reports (Monthly Status Reports), a start-up schedule, an as-built schedule report, and revisions to the schedules and analyses as prescribed. The planning, scheduling, management, and execution of the work is the sole responsibility of the Contractor. The progress schedule requirement is established to allow OWNER to review Contractor’s planning, scheduling, management and execution of work; to assist OWNER in evaluating work progress and make progress payments; to allow other contractors to cooperate and coordinate their activities with those of the Contractor; and to provide OWNER with information about “construction schedule” and “cumulative outlay schedule” to be forwarded to FDEP, or other funding agencies, if applicable.

C. OWNER’s review of the schedule submittals shall not relieve Contractor from responsibility for any deviations from Contract

ITB No.: 26-403/DL 01310 - 3

Documents unless Contractor has in writing called OWNER’s attention to such deviations at the time of submission and OWNER has given written concurrence to the specific deviations, nor shall any concurrence by OWNER relieve Contractor from responsibility for errors and omissions in the submittals.

Concurrence of the CPM Activity Network by the OWNER is advisory only and shall not relieve the Contractor of responsibility for accomplishing the work within the Contract completion date(s).

D. The concurred base schedule, shall have legal status as long as it is used by Contractor for planning, organizing, directing, managing, and executing the work in accordance with the Contract Documents. Legal status will further imply that Contractor will use the schedule to report progress and, further, that Contractor and OWNER will use the schedule for determining delay(s) in achieving the Contract Date(s)stipulated in the Agreement subject to the requirements of this section of the General Requirements.

E. OWNER will, upon receipt and review of each schedule submittal, either indicate in writing a recommendation of concurrence or return the submittal to Contractor indicating in writing OWNER’s reasons for refusing to recommend concurrence. In the latter case, Contractor will be required to make the necessary corrections and resubmit. If Contractor fails to provide submittals as required, he/she will be deemed not to have provided a basis upon which progress may be evaluated, which may constitute reasons for refusing to recommend progress payments.

F. OWNER’s review of the schedule submittals shall be only for conformance with the information given in the Contract Documents and shall not extend to the means, methods, sequences and techniques or procedures of construction or to safety precautions or programs incident thereto. OWNER’s review of the schedule submittals will be predicated on a contractor’s stamp of approval signed off by Contractor and those subcontractors and suppliers performing work under an appropriate agreement with Contractor. Contractor’s stamp of approval on any schedule submittal shall constitute a representation to OWNER that Contractor has either determined or verified all data on the submittal, or assumes full responsibility for doing so, and that Contractor and his subcontractors and suppliers, have reviewed and coordinated the sequences shown in the submittal with the requirements of the work under the Contract Documents.

2.02 FORM OF SCHEDULES

A. Prepare schedules in the form of a horizontal bar chart diagram.

The diagram shall be time-scaled and sequenced by work areas.

ITB No.: 26-403/DL 01310 - 4

Horizontal time scale shall identify the first work day of each week.

B. Activities shall be at least as detailed as the Bid Schedule and Schedule of Values. Activity durations shall be in whole working days. In addition, activity man-days shall be shown for each activity or alternatively, tabulated in an accompanying report.

C. Diagrams shall be neat and legible and submitted on sheets at least 24 inches by 36 inches suitable for reproduction. Scale and spacing shall allow space for notations and future revisions.

D. The program disk, the diagrams and reports shall be prepared by using Primavera Project Planner 5.1 or latest version. A copy of the Primavera project files using the Primavera Project Planner “back-up” menu selection shall be prepared. Furnish the information on a USB with each individual submittal.

2.03 CONTENT OF SCHEDULES

A. Each monthly schedule shall be based on data as of the last day of the current pay period.

B. Description for each activity shall be brief but convey the scope of work described. Each activity shall be cost loaded.

C. Activities shall identify all items of work that must be accomplished to achieve substantial completion, such as items pertaining to Contractor’s installation and testing activities, items pertaining to the approval of regulatory agencies;

Contractor’s time required for submittals, fabrication and deliveries; the time required by ENGINEER to review all submittals as set forth in the Contract Documents; items of work required of OWNER to support pre-operational, startup and final testing; time required for the relocation of utilities.

Activities shall also identify interface milestones with the work of other contractors performing work under separate contracts with OWNER.

1. Where work is to be performed under this Contract concurrently with and/or contingent upon work performed on the same facilities or area under other contracts, the Contractor’s schedule shall be coordinated with the schedules of the other contracts. The Contractor shall obtain the schedules of the other appropriate contacts for the preparation and updating of his schedule and shall make the required changes in his schedule when indicated by changes in corresponding schedules.

D. Schedules shall show the complete sequence of construction by activities. Date for beginning and completion of each activity

ITB No.: 26-403/DL 01310 - 5 shall be indicated as well as projected percentage of completion for each activity as of the first day of each month.

E. Submittals schedule for shop drawings review, product data, and samples shall show the date of Contractor submittal and the date approved submittals will be required by the OWNER, consistent with the time frames established in the Specifications.

F. For Contract Change orders granting time extensions, the impact on the Contract Date(s) shall equal the calendar-day total time extension specified for the applicable work in the Contract Change order.

G. For actual delays, add activities prior to each delayed activity on the appropriate critical path(s). Data on the added activities of this type shall portray all steps leading to the delay and shall further include the following: separate activity identification, activity description indicating cause of the delay, activity duration consistent with whichever set of dates below applies, the actual start and finish dates of the delay or, if the delay is not finished, the actual start date and estimated completion date.

H. For potential delays, add an activity prior to each potentially delayed activity on the appropriate critical path(s). Data for added activities of this type shall include alternatives available to mitigate the delay including acceleration alternatives, and further show the following: separate activity identification, activity description indicating cause of the potential delay, and activity duration equal to zero work days.

I. The contract completion time will be adjusted only for causes specified in this Contract. In the event the Contractor requests an extension of any contract completion date, he shall furnish such justification and supporting evidence as the OWNER may deem necessary for a determination as to whether the Contractor is entitled to an extension of time under the provision of this Contract. OWNER will, after receipt of such justification and supporting evidence make findings of fact and will advise the Contractor in writing thereof. If the OWNER finds that the Contractor is entitled to any extension of any contract completion date under the provision of this Contract, the OWNER’s determination as to the total number of days extension shall be based upon the currently concurred schedule and on all data relevant to the extension. Such data shall be included in the next monthly updating of the schedule. The Contractor acknowledges and agrees that actual delays in the activities which, according to the schedule, do not affect any contract completion date shown by the critical path in the schedule and do not have any effect on the contract completion date or dates, and therefore, will not be the basis for a change therein.

ITB No.: 26-403/DL 01310 - 6

J. From time to time, it may be necessary for the contract schedule and/or completion time to be adjusted by the OWNER to reflect the effects of job condition, weather, technical difficulties, strikes, excusable delays on the part of the OWNER or his representatives, and other unforeseeable conditions which may indicate schedule adjustments and/or completion time extension.

Under such conditions, the Contractor shall reschedule the work and/or contract completion time to reflect the changed conditions, and the Contractor shall revise his schedule accordingly. No additional compensation shall be made to the Contractor for such schedule changes except for excusable overall contract time extension beyond the actual completion of all unaffected work in the Contract, in which case the Contractor shall take all possible action to minimize any time extension and any additional cost to the OWNER. It is specifically pointed out that the use of available float time in the schedule may be used by the OWNER as defined by the OWNER, as well as by the Contractor. Float time is defined as the amount of time between the early start date, and the late start date, or the early finish date and the late finish date, of any of the activities in the schedule.

K. The OWNER controls the float time in the concurred schedule, and therefore without obligation to extend either the overall completion date or any intermediate completion dates set out in the schedule, the OWNER may initiate changes to the Contract work that absorb float time only. OWNER-initiated changes that affect the critical path on the approved schedule shall be the sole grounds for extending (or contracting) said completion dates. Contractor-initiated changes that encroach on the float time identified in the concurred schedule may be accomplished with the OWNER’s concurrence. Such changes, however, shall give way to OWNER-initiated changes competing for the same float time.

2.04 SUPPORTING NARRATIVE

A. Status and Scheduling reports identified below shall contain a narrative (progress report) to document the project status, to explain the basis of Contractor’s determination of durations, describe the contract conditions and restraints incorporated into the schedule, and provide an analysis pertaining to potential problems and practical steps to mitigate them.

B. The narrative shall specifically include:

1. Actual completion dates for activities completed during the report period, and actual start dates for activities commenced during the report period.

2. Anticipated start dates for activities scheduled to commence during the following report period.

ITB No.: 26-403/DL 01310 - 7

3. Changes in the duration of any activity and minor logic changes.

4. The progress along the critical path in terms of days ahead or behind the Contract Date.

5. If the Monthly Status Report indicates an avoidable delay to the Contract Completion date or interim completion dates as specified in the Agreement, Contractor shall identify the problem, cause and the activities affected and provide an explanation of the proposed corrective action to meet the milestone dates involved or to mitigate further delays.

6. If the delay is thought to be unavoidable, the Contractor shall identify the problem, cause, duration, specific activities affected and logic restraints of each activity.

7. The narrative shall, in addition, also discuss all change order activities whether included or not in the revised/current schedule of legal status. Newly introduced change order work activities, and the CPM path(s) that they affect, must be specifically identified. All Change Order work activities added to the schedule shall conform with the sequencing and Contract Time requirements of the applicable Change Order.

8. Original Contract date(s) shall not be changed except by Contract Change Order. A revision, as specified in Article

2.09 below, need not be submitted when the foregoing situations arise unless required by OWNER. Review of a report containing added activities will not be construed to be concurrence with the duration or restraints for such added activities; instead, the corresponding data as ultimately incorporated into the applicable Contract Change Order shall govern.

9. Should OWNER require additional data, this information shall be supplied by Contractor within ten (10) calendar days.

C. Progress under the concurred CPM schedule shall be evaluated monthly by the Contractor and the OWNER. Once each month, at a time mutually agreed upon, the Contractor and the OWNER shall hold a Construction Progress Meeting at a location designated by the OWNER. This meeting shall be attended by the Contractor’s highest ranking field manager and scheduler, if requested by the OWNER, the designated home office project managers or officers.

Similar representatives of the Contractor’s mechanical and electrical subcontractors as well as any other subcontractors or suppliers designated by the OWNER, shall also attend the meetings. At the meetings all matters relating to job progress will be discussed, and commitments made will be considered as binding. Not less than seven (7) calendar days prior to each monthly construction progress meeting, the Contractor and OWNER shall meet at the job site and jointly evaluate the status of

ITB No.: 26-403/DL 01310 - 8 each activity on which work has started or is due to start based on the preceding monthly CPM schedule.

2.05 SUBMITTALS

A. Contractor shall submit Base and Status Progress Schedules, monthly status reports, a start-up schedule, and an as-built schedule report all as specified herein.

B. No payments for mobilization will be processed thru the OWNER until the Base Schedule for the project has been concurred with by the OWNER.

C. All schedules, including base and preliminary status, shall be in conformance with Articles 2.01, 2.02, and 2.03 above. The lack or failure to submit a properly concurred base or status update schedule to the OWNER will be sufficient reason by the OWNER to decline recommendation of any progress payments, including percentages for mobilization payments.

D. The finalized progress schedule discussed in the General Conditions shall be the first monthly status report and as such shall be in conformance with all applicable specifications contained herein.

E. Monthly Status Report submittals shall include five (5) color copies of a time-scaled (days after notice to proceed) diagram showing all contract activities; five (5) copies of network logic tabular reports by activity, early and late start, total float, successor/predecessor and supporting narrative. The detailed base schedule shall use the notice to proceed as the data date. The Schedule, if concurred with by OWNER pursuant to paragraph 2.01(E), shall be the work plan to be used by the Contractor for planning, scheduling, managing, and executing the work.

F. The schedule diagram shall be formatted in accordance with Article 2.02 above. The diagram shall include (1) all detailed activities included in the preliminary and base schedule submittals, (2) calendar days prior to substantial completion,

(3) summary activities for the remaining sixty (60) days. The critical path activities shall be identified, including critical paths for interim dates, if applicable.

G. Contractor shall submit monthly progress schedules with each month’s application for payment. OWNER will review schedules and return review copy within twenty (20) days after receipt.

If required, Contractor shall resubmit within seven (7) days after return of review copy.

ITB No.: 26-403/DL 01310 - 9

H. Contractor shall submit the number of monthly status reports which the Contractor requires, plus five (5) copies which will be retained by the OWNER.

2.06 MONTHLY STATUS REPORTS

A. Contractor shall submit five (5) copies of detailed schedule status reports on a monthly basis with the Application for Payment. The first such status report shall be submitted with the first Application for Payment and include data as of the last day of the pay period. The Monthly Report shall include a revised copy of the latest detailed schedule of legal status, tabular reports and a supporting narrative including updated information as described in paragraph 2.04. The Monthly Report will be reviewed by OWNER and Contractor at a monthly schedule meeting, and Contractor will address OWNER’s comments on the subsequent monthly report. Monthly status reports shall be the basis for evaluating Contractor’s progress.

B. The revised diagram shall show, for the latest detailed schedule of legal status, percentages of completion for all activities, actual start and finish dates, and remaining durations, as appropriate. Activities not previously included in the latest detailed schedule of legal status shall be added, except that contractual dates will not be changed except by change order.

Review of a revised diagram by OWNER will not be construed to constitute concurrence with the time frames, duration, or sequencing for such added activities; instead, the corresponding data as ultimately incorporated into an appropriate Change Order shall govern.

2.07 STARTUP SCHEDULE

A. At least ninety (90) calendar days prior to the date of substantial completion, Contractor shall submit a time-scaled (days after notice to proceed) diagram detailing the work to take place in the period between sixty (60) days prior to substantial completion and substantial completion, together with a supporting narrative. OWNER shall have twenty (20) calendar days after receipt of the submittal to respond. Upon receipt of OWNER’s comments, Contractor shall make the necessary revisions and submit the revised schedule within ten (10) calendar days. The resubmittal, if concurred with by OWNER, shall be the Work plan to be used by Contractor for planning, managing, scheduling and executing the remaining work leading to substantial completion.

B. The time-scaled diagram shall use the latest schedule of legal status for those activities completed ahead of the last sixty

(60) calendar days prior to substantial completion, and detailed

ITB No.: 26-403/DL 01310 - 10 activities for the remaining sixty (60) day period within the time frames outlined in the latest schedule of legal status.

C. Contractor will be required to continue the requirement for monthly reports, as outlined in Article 2.05 above. In preparing this report, Contractor must assure that the schedule is consistent with the progress noted in the startup schedule.

2.08 AS-BUILT SCHEDULE

A. After substantial completion but prior to final payment, Contractor shall submit an as-built schedule report and time-scaled as-built diagram. The documents shall reflect all as-built critical paths. The diagram shall be prepared in accordance with Articles 2.02 and 2.03, in addition to the following:

1. All Contract activities, including all added activities, shall be shown.

2. Activity durations shall be the actual number of separate work days during which work was performed on the activity.

3. Contract milestone completions shall be plotted on the date of the Substantial Completion Reports.

2.09 REVISIONS

A. All revised Schedule Submittals shall be made in the same form and detail as the initial submittal and shall be accompanied by an explanation of the reasons for such revisions, all of which shall be subject to review and concurrence by OWNER. The revision shall incorporate all previously made changes to reflect current as-built conditions. Minor changes to the approved submittal may be approved at monthly meetings; a minor change is not considered a revision in the context of this paragraph.

B. A revised schedule submittal shall be submitted for review, when required by OWNER, for one of the following reasons:

1. OWNER directs a change that affects the date(s) specified in the Agreement or alters the length of a critical path.

2. Contractor elects to change any sequence of activities so as to affect a critical path of the current schedule documents.

C. If, prior to agreement on an equitable adjustment to the Contract Time, OWNER requires revisions to the schedule in order to evaluate planned progress, Contractor shall provide an interim revised submittal for review with change effect(s) incorporated as directed. Interim revisions to the documents which are recommended to the OWNER for concurrence will be incorporated in the next Monthly Status Report.
