The project design engineers, FHWA, key company representatives, and key local government personnel will also be invited to attend as

D-12 necessary. The contractor and DOTD will also be required to have Regional/District and Corporate/State level managers on the project team.

Any cost associated with effectuating this partnering will be agreed to by both parties and will be shared equally and will be paid for in accordance with Subsection 109.4. The contractor, DOTD, FHWA and all others invited to the partnering conference will be responsible for any expenses incurred by their respective employees which includes salaries, travel, and lodging.

Follow-up conferences may be held periodically throughout the duration of the contract as agreed by the contractor and the DOTD.

S.P. PRE-AWARD CPM

FOR CONTRACT TIME REVIEW (01-26):

Should only one bid be received then the single bidder shall be required to gain approval from the Chief Construction Engineer, as outlined below, prior to the Award of Contract. A Pre-Award CPM shall only be used for review and justification of the contract time submitted as part of the bid.

Critical Path Methods (CPM) as described and with terms as defined in the Associated General Contractors of America (AGC) publication, Construction Planning and Scheduling, shall be used in construction scheduling and establishing the critical items of work. In case of discrepancy between these specifications and Construction Planning and Scheduling, these specifications shall govern.

The Single Bidder shall submit to the Chief Construction Engineer for approval, CPM Construction Schedules and Summary of Activities tabulations, all as described hereinafter, and altogether defined as "Construction Schedule". The Construction Schedule shall be based on the planned work, the proposed maintenance of traffic restrictions, and other design requirements given in the plans and specifications. Each sheet or page of each submittal shall be identified with the contractor's company name, state project number, project name, date prepared, revision dates, and sheet or page number. If the submittals are not prepared by the contractor's own staff, the company name of the preparer shall be shown on each sheet or page.

The critical activities as shown on the Construction Schedule will be considered in establishing the controlling item of work. If the Construction Schedule is not approved by the Chief Construction Engineer the bid will be considered irregular and will be rejected.

The sequence of work as represented on the approved Construction Schedule and approved associated data shall be interpreted as being the intention of the contractor at the time that the schedule was made.

CONSTRUCTION SCHEDULE

The Construction Schedule shall be a Critical Path Method (CPM) graphic diagram, computer prepared, utilizing the Precedence Diagramming Method (PDM). For the calendar day contract, the Gregorian calendar shall be used.

The schedule shall show and describe the various activities of work required to complete the contract in sufficient detail so that all activities are readily identifiable and progress on the activities can be readily measured. Sufficient detail in bridge work means each element of work (piles, footings, columns, caps, rebar, cure time, etc.) of individual bents; each element of work in individual spans (girders, strip seal joints, Structural Class A1, rebar, cure time, etc.); individual approach slabs; railings; rebar for all of the above as separate activities; and, miscellaneous other bridge work. Sufficient detail in road work means individual runs of pipe

D-23 in drainage structures; individual box culverts; individual detour roads; the embankment, excavation, base and paving layers within definable geometric limits (e.g., from station to station, within a single ramp, etc.). Physical locations of activities within definable geometric limits (e.g., from station to station, within a single ramp, individual bents, individual spans, etc.) shall be included in the activity description or shown in activity codes relative to each activity. It shall include submittals and approvals of critical samples, shop drawings, procedures, order lists (pilings for example), or other things that could have a significant schedule impact.

Relatively minor items of work, similar or non-similar, may be grouped together into one activity (or more). Activities to be performed by subcontractors shall be included and identified. The schedule shall show the sequence in which the activities are to be accomplished and their dependency relationships. The pay item quantities associated with each activity shall be included and shall equal the current contract amount.

The duration of activities shall be in whole calendar days and no activity shall have duration of less than one calendar day or more than 30 calendar days. The ending event of the schedule shall be a finish milestone identified as “Contract Completion Date”. Its sole predecessor shall be “Reserved Float”. The sole predecessor of “Reserved Float” shall be “Final Inspection” which shall be a finish milestone and shall have as predecessors all of the activities that must be completed prior to the Department’s final inspection of the work. The duration of “Reserved Float” is the difference between “Final Inspection” and “Contract Completion Date”. “Reserved Float” is defined as that part of the shared float reserved exclusively for the contractor’s use. The contract date for stipulated damages will be adjusted by change order to the beginning date of the activity “Reserved Float”.

The Construction Schedule shall be computer plotted on sheets not larger than 22 inches x 36 inches and shall show a continuous flow of information from left to right with no arrows from right to left and shall be drawn to a time scale of calendar days. The critical path shall be clearly identified. Resource constraints shall be identified, as shall scheduled starts or completions imposed on the schedule by the contractor.

The contractor shall submit color-coded graphics in the required multiple copies.

The contractor shall provide the Department with the means to electronically translate the Construction Schedule data into a configuration that can be read and processed by the Department or its consultants' hardware and Primavera software. If the contractor elects to use SureTrak Project Manager software, the following defaults must be placed: (1) resources shall be non-driving; (2) default activity type shall be "Task"; (3) activity type shall not be "Independent"; (4) duration display style shall be "Day (d)"; (5) float style shall be "Days";

and, (6) dates time format shall be "Don't show time". In both the SureTrak Project Manager and in the Primavera Project Planner (P3) "Back up" menu selection, the contractor will ensure that the option "Remove access list during backup" is checked. In addition, the project must be saved in SureTrak as a "Concentric P3" Type project.
