SECTION 01 32 16.16

NETWORK ANALYSIS SCHEDULES (DESIGN-BUILD ONLY)

PART 1- GENERAL

1.1 DESCRIPTION:

A. The Contractor shall develop a fully Resource loaded (cost and manpower) Network Analysis

System (NAS) plan and computer generated schedule demonstrating fulfillment of the entire contract requirements, shall keep the plan and computer generated schedule up-to-date in accordance with the requirements of this section and shall utilize the plan for scheduling, coordinating, mitigating and monitoring work under this contract (including all activities of subcontractors, equipment vendors and suppliers). The Contractor’s initial NAS Diagram submission will be the basis for their initial project schedule and will be designated as a Day

1 submission. After review and approval by VA, this schedule will be designated as the approved Baseline Schedule.

B. Conventional Critical Path Method (CPM) Precedence Diagramming Method (PDM) technique shall be utilized to satisfy both time and cost applications. All schedule data and reports required under this specification section shall be based upon total float, not relative or free float schedules. The approved baseline NAS diagram and the schedule becomes the official project schedule of record governing schedule management, oversight and actions on the corresponding contract.

1.2 CONTRACTOR'S REPRESENTATIVE:

A. The Contractor shall designate an authorized representative in the firm who will be responsible for the preparation of the network diagram, review and report progress of the project with and to the Contracting Officer's representative.

B. The Contractor's representative shall have direct project control and complete authority to act on behalf of the Contractor in fulfilling the requirements of this specification section and such authority shall not be interrupted throughout the duration of the project.

1.3 CONTRACTOR'S CONSULTANT:

A. To fulfill all of the requirements of this specification section, the Contractor shall engage an independent Critical Path Method (C.P.M) consultant who is skilled in the time and cost application of scheduling using (PDM) network techniques for similar sized construction

01 32 16.16 - 2 projects. The cost of which is included in the Contractor's bid proposal price. This consultant shall not have any financial ties, business ties, affiliation with or a subsidiary company of the

Contractor. The consultant is expected to provide unbiased professional services to the contractor and to Veterans Affairs Contracting Officer Representative (C.O.R) in developing and maintaining the project schedule.

Contractor shall submit to the Contracting Officer and Contracting Officer Representative

1. The name and address of the proposed consultant and Company.

2. Sufficient information to show that the proposed consultant has the qualifications to meet the requirements specified in this specification section.

3. A list of prior construction projects, along with selected Precedence Diagramming

Method PDM network diagram samples on current projects which the proposed consultant has performed complete project scheduling services. These network diagram samples must show complete project planning for a project of similar size and scope as covered under this contract.

C. The Contracting Officer and Contracting Officer Representative has the right to approve or disapprove employment of the proposed consultant and will notify the Contractor of the

Veterans Affairs (V.A) decision within seven calendar days from receipt of information. In case of disapproval, the Contractor shall resubmit another consultant within 10 calendar days for renewed consideration. The contractor must have their CPM Consultant approved prior to:

1. Submitting the Day 1 diagram and schedule.

2. Notice to Proceed.

3. Pre-construction Conference.

1.4 PRIOR TO BASELINE SCHEDULE ACCEPTANCE

A. At the time of the Pre-Construction Conference, prior to the issuance of the project Notice to

Proceed, the Contractor and the Contractor’s Scheduling Consultant shall arrange a separate meeting with the Contracting Officer and/or his representative to discuss the requirements of this specification.

01 32 16.16 - 3

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

Network Analysis System (N.A.S) 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.

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 Representative (C.O.R) The contractor shall make a separate written detailed request to the C.O.R 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.

01 32 16.16 - 4

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, 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.

3. 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 Representative (C.O.R) 's review and approval of shop drawings, equipment schedules samples, template, or similar items with time duration of no less than 20 workdays.

4. Shutdowns or Interruption of Veterans Affair Medical Center utilities, delivery of

Government furnished equipment (GFE), and rough-in drawings, project phasing and any other specification requirements.

5. 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.

J. Veterans Affairs 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

01 32 16.16 - 5 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.

2.2 RESPONSIBILITY FOR COMPLETION / PROJECT DELAY

A. Whenever it becomes apparent from the current monthly progress review meeting or the monthly schedule update that phasing or contract completion dates will not be met, the

Contractor shall execute some or all of the following remedial actions:

1. Increase construction manpower in such quantities and crafts as necessary to eliminate the backlog of work.

2. Increase the number of working hours per shift, shifts per working day, working days per week, the amount of construction equipment, or any combination of the foregoing to eliminate the backlog of work.

3. Reschedule the work in conformance with the specification requirements to recover all of the delay for which the contractor is responsible.

B. Prior to proceeding with any of the above actions, the Contractor shall notify and obtain approval from the Contracting Officer for the proposed schedule changes. If such actions are approved, the contractor shall incorporate this “Recovery schedule” with all the CPM revisions into the next update, at no additional cost to the Government.

3.4 ADJUSTMENT OF CONTRACT COMPLETION DATE / TIME EXTENSION DUE TO

CHANGES TO THE CONTRACT

A. Contract Time Extension due to Changes to Contract - The contract completion time will be adjusted only for causes specified in this contract. The contractor shall submit Request for a time extension to the contract within reasonable time frame (within 1 month of the issuance of the Change order or before signing of the bilateral Supplemental Agreement) and must provide a justification, Conventional Critical Path Method (CPM) data and supporting evidence as the Contracting Officer may deem necessary for determination as to whether or not the Contractor is entitled to a time extension under the provisions of the contract.

01 32 16.16 - 6

Submission of proof based on revised activity/event logic, durations (in work days) and costs is obligatory to any approvals. The schedule must clearly display that the Contractor has used, in full, all the float time available for the work involved in this request. The Contracting

Officer's determination as to the total number of days of contract extension will be based upon the current computer-produced calendar-dated schedule for the time period in question and all other relevant information.

B. Actual delays in activities/events which, according to the computer-produced calendar-dated schedule, do not affect the original or extended contract completion dates shown by the critical path in the network, will not be the basis for a change to the contract completion date.

The Contracting Officer will within a reasonable time after receipt of such justification and supporting evidence, review the facts and advise the Contractor in writing of the Contracting

Officer's decision. The burden of proof to request the time extension is the sole responsibility of the contractor, and the contractor is required to revise the Time analysis or provide further documentation when requested by the Contracting Officer.

C. The Contractor shall submit each request for a change in the contract completion date to the

Contracting Officer in accordance with the provisions specified under Article, FAR 52.243 -4 (CHANGES).

The Contractor shall include, as a part of each change order proposal, a sequence of activities showing all CPM logic revisions (Fragnet), duration (in work days) changes, and cost changes, manpower loading for work in question and its relationship to other activities on the approved network diagram (as specified above in item 3.2.E – Parallel Run /Time

Impact Analysis).

3.6 ADJUSTMENT OF CONTRACT COMPLETION DATE / TIME EXTENSION DUE TO

WEATHER:

Weather Delays - All delays due to non-work activities/events such as Request For

Information (R.F.I’s) Weather, Strikes, and similar non-work activities/events shall be analyzed on a month by month basis.

Any weather-related delays claimed by the contractor must be “above and beyond” the

“normal weather” pattern (10-year average) and shall be supported by the data shown in the

National Oceanic and Atmospheric Administration (NOAA) for the region of the country

01 32 16.16 - 7 where the project site is located. It is obligatory for the contractor to prove that time delays claimed due to unusual weather have directly impacted the critical path related work.

The weather delay analysis shall be submitted to the Veterans Affairs (V.A) within 30 calendar days after the weather event has passed. VA considers Time extension due to the weather is “non-compensable” time only.
