Scheduling Consultant shall arrange a separate meeting with the

Contracting Officer and/or his representative to discuss the requirements of this specification.

B. With exception of bonds, insurance, and limited mobilization cost associated with preparatory work such as site trailers, staging areas, haul roads etc., the approval of the baseline NAS schedule is a condition precedent to:

1. Processing of contractor’s pay request(s) for any construction activities/items of work.

2. Review of any schedule updates.

01 32 16.13 - 3

C. Government review comments on the contractor’s schedule shall not relieve the contractor from compliance with requirements of this specification section and the remaining contract documents.

PART 2 - SCHEDULE CRITERIA / DATA REQUIREMENTS:

2.1 COMPUTER PRODUCED SCHEDULE DEVELOPMENT CRITERIA

A. The computer produced schedule shall be prepared and maintained using

Primavera P6 software.

B. Work activity/event relationships shall be restricted to Finish-to-

Start (FS) and Start-to-Start (SS) only without lead or lag constraints. Note: Some exception may be allowed for lag in SS relationship, but must be approved by the VA’s contracting officer on case by case basis prior to inclusion in the schedule.

C. Activity/event date constraints, not required by the contract, will not be accepted unless submitted to and approved by the Contracting

Officer. The contractor shall make a separate written detailed request to the Contracting Officer identifying these date constraints and secure the Contracting Officer’s written approval before incorporating them into the network diagram. The Contracting Officer’s separate approval of the network diagram shall not excuse the contractor of this requirement.

D. Logic events (non-work) will be permitted where necessary to reflect proper logic among work events, but must have zero duration. The complete computer schedule shall reflect the Contractor's approach to pursuing the entire project.

E. Intermediate Phasing milestones contained in the contract documents shall be clearly shown in the schedule.

F. The Contractor’s initial Day 1 submission, prior to VA review and approval, in its original form shall reflect the original contract scope of work.

G. Early Project Completion or “Short Schedule” – VA will not approve any baseline schedule which shows completion date prior to the contract completion date. Also, there should not be any “filler or

“contingency” type of activities to fill the entire contract duration.

VA has no obligation to accelerate activities to support a proposed early contract completion. However, if the subsequent updates show that early handover is feasible due to “ahead of schedule” situation, 01 32 16.13 - 4

VA may accept the facility earlier at no additional cost to the government.

H. The Baseline Schedule Critical Path of the project shall be limited to:

1. No more than 20% of the activities shall be on the critical and near-critical path(s). Critical path is defined as activities with zero (0) day total float. Near-Critical path(s) is defined as activities with one (1) to twenty (20) days of total float.

2. Multiple Critical paths will not be allowed.

I. The Contractor shall show activities/events for:

1. Contractor's time required for submittal of shop drawings, templates, fabrication, delivery and similar pre-construction work.

2. Contracting Officer's and Architect-Engineer's review and approval of shop drawings, equipment schedules samples, template, or similar items with time duration of no less than 20 workdays.

3. Shutdowns or Interruption of VA Medical Center utilities, delivery of Government furnished equipment (GFE), and rough-in drawings, project phasing and any other specification requirements.

4. VC/VV Equipment - All significant VC (VA furnished and Contractor installed) and VV (VA furnished and VA installed) equipment shall be clearly shown in the schedule. Any smaller VC and VV Equipment shall also be logically grouped together and shown in the schedule.

5. Test, balance and adjust various systems and pieces of equipment, maintenance and operation manuals, instructions and preventive maintenance tasks.

6. Commissioning (Cx)Activities – Based upon the project specific

Commissioning plan and project specification section 01 91 00, the contractor shall include in the Day 1 NAS Diagram all the systems commissioning activities (see systems covered in Division 7, 8, 21, 22, 23, 26, 28, 31 and others as specified) such as start up, Pre-functional check list, Pre–test, individual component and system level Functional test, Operator’s training, O.& M. Manuals etc.(including any deficiency correction and re-testing). The majority of commissioning activities should be completed as part of the normal construction schedule and finalized prior to the construction contract completion date. To this end, it is imperative that the Commissioning Agent and the Contractor collaborate to integrate commissioning activities into the

Contractor’s overall construction schedule. All commissioning

01 32 16.13 - 5 activities shall be cost loaded as required in the earlier paragraphs. The Commissioning Plan will identify critical commissioning activities and associated construction/start up tasks that must precede these activities to allow for successful execution of the commissioning activities. In order to coordinate these activities with the construction schedule, a Commissioning Duration

Schedule should be provided by the Commissioning Agent to the VA SRE and the Contractor to provide a rational basis for integration of commissioning into the Day 1 NAS diagram and the construction schedule. The Commissioning Duration Schedule should include the following information:

I. Description of Commissioning Activity

II. Prerequisite Construction Tasks Required to Execute the Cx Activity

III. Elapsed Time Duration of Each Activity

IV. Documentation Associated with Each Task/Document

Responsibility

7. Once the duration schedule is delivered to the Contractor, the

Contractor will collaborate with the Commissioning Agent to integrate all commissioning activities into the fixed duration construction schedule in accordance with VA NAS requirements for scheduling the project. The Baseline Schedule, as approved by the VA at the beginning, may not have all necessary Cx details, but the contractor is required to subsequently update the commissioning activities as more detailed Commissioning Duration Schedule is being developed.

J. VA inspection and acceptance activity/event with a minimum duration of five work days at the end of each phase and immediately preceding any

VA move activity/event required by the contract phasing for that phase.

Schedule these activities/events so that only one phase is scheduled for completion within the same 30 consecutive calendar day period

(except for those phases immediately preceding the final acceptance).

Maintain this scheduling condition throughout the length of the contract unless waived by the Contracting Officer’s representative in writing.

K. Work activities/events for the asbestos abatement bid item shall have a trade code of ASB.

01 32 16.13 - 6

L. Bid items other than the Base Bid (ITEM 1) and Asbestos Abatement item shall have trade codes corresponding to the appropriate bid item number

(e.g., ITM 3, ITM 4 and other items).

1. Show not only the activities/events for actual construction work for each trade category of the project, but also trade relationships to indicate the movement of trades from one area, floor, or building, to another area, floor, or building, for at least five trades who are performing major work under this contract.

2. Break up the work into activities/events shall have:

a. Duration no longer than 20 work days each, except as to non-construction activities/events (i.e., procurement of materials, delivery of equipment, concrete and asphalt curing) and any other activities/events for which the Contracting Officer may approve the showing of a longer duration.

b. The duration for VA approval of any required submittal, shop drawing, or other submittals shall not be less than 20 work days.

Refer to drawing CPM-1 for VA approval activities/events which will require minimum duration longer than 20 workdays. The construction time as determined by the CPM schedule from early start to late finish for any sub-phase, phase or the entire project shall not exceed the contract time(s) specified or shown.

c. An activity/event shall only reflect the work of one entity

(subcontract or craft).

d. The activity/event once began can continue unimpeded until the activity/event is complete.

3. Describe work activities/events clearly, so the work is readily identifiable with clear scope for assessment of completion.

Activities/events labeled "start," "continue," or "completion," are not specific and will not be allowed. Lead and lag time activities will not be acceptable (Refer to item 2.1 B above for some exceptions).

4. Uniquely number each activity/event ID with ALPHA-NUMERIC value in ascending order. The network diagram should be generally numbered in such a way to reflect trade discipline, phase or location of the work.

2.2 WORK ACTIVITY/EVENT COST AND TRADE RESOURCE DATA

A. Cost Loading - The Contractor shall cost load all work activities/events except procurement activities. The cost loading shall

01 32 16.13 - 7 reflect the appropriate level of effort of the work activities/events.

The cumulative amount of all cost loaded work activities/events

(including alternates) shall equal the total contract price. Prorate overhead, profit and general conditions on all work activities/events for the entire project length. The contractor shall generate from this information cash flow curves indicating graphically the total percentage of work activity/event dollar value scheduled to be in place on early finish, late finish. These cash flow curves will be used by the Contracting Officer to assist him in determining approval or disapproval of the cost loading. In the event of disapproval, the

Contractor shall revise and resubmit in accordance with Article, THE

INITIAL DAY ONE SCHEDULE SUBMITTAL (Item 3.1B below). Negative work activity/event cost data will not be acceptable, except on VA issued contract changes.

B. The Contractor shall cost load work activities/events for guarantee period services, test, balance and adjust various systems in accordance with the provisions in the FAR 52.232 – 5 (PAYMENTS UNDER FIXED-PRICE

CONSTRUCTION), Article, and VAAR 852.236 - 83(PAYMENTS UNDER

FIXED-PRICE CONSTRUCTION).

C. The Contractor shall cost load work activities/events for ASBESTOS

ABATEMENT. The sum of asbestos abatement work activity/event costs shall equal the value of the asbestos bid item in the Contractors' bid.

ITEMS. The sum of the cost loading for each bid item work activities/events shall equal the value of the item in the Contractors' bid.

E. Work activities/events for Contractor bond shall have a trade code and area code of BOND.

F. Manpower loading - In accordance with Article PERFORMANCE OF WORK BY

THE CONTRACTOR in FAR 52.236 – 1 and VAAR 852.236 - 72, the Contractor shall submit, simultaneously with the cost per work activity/event of the construction schedule required by this Section, a responsibility code for all activities/events of the project for which the

Contractor's forces will perform the work. This shall be the basis for the “Resource loading” of the schedule and the contractor shall provide

“Manpower loading” reports by trades and the overall Trade manpower requirements, when requested by the contracting officer or his/her representatives.
