Project Schedule Updates

Monthly updates: The monthly updating of the project schedule shall be an integral part and basic element of the estimate upon which progress payments shall be made under this contract. If, in the judgment of the Contracting Officer, the DBC fails or refuses to provide a schedule of values and a complete schedule update or revision as specified hereinafter, the DBC shall be deemed to have not provided the required information upon which the progress payment may be made, and shall be subject to retainage of a portion of the payment.

Narrative: The report shall include a brief description of the actual progress made during the update period; actual and potential delaying activities; any impediments to progress; issues related to inclement weather; progress toward established milestones and project float. The report shall include a brief description of the work anticipated to be performed in the next month. Any minor revisions to the schedule should be identified so they can be evaluated and accepted or rejected.

As the Work progresses, indicate Actual Completion percentage for each activity.

If the schedule update shows a late finish date after the contract completion date, at a minimum, include the following in the narrative with your submission:

Any known delays.

Actions that will be taken to get back on schedule.

Pending modifications.

Impediments or constraints affecting progress.

Progress Payments: The monthly updating of the currently accepted Construction Schedule shall be an integral part of the process upon which progress payments will be made under this contract. If the

Contractor fails to provide schedule updates or revisions, then a portion of the monthly payment may be retained until such corrections have been made.

Time Impact Analysis for Contract Modifications, Changes, Delays, and Contractor Requests

Requirements: When contract modifications or changes are initiated, delays are experienced, or the

DBC desires to revise the project schedule, the DBC shall submit to the Contracting Officer a written time impact analysis illustrating the influence of each modification, change, delay, or DBC request on the contract time.

Time Extensions: Activity delays shall not automatically mean that an extension of the contract time is warranted or due the DBC. It is possible that a modification, change, or delay will not affect existing critical activities or cause non-critical activities to become critical. A modification, change, or delay may result in only absorbing a part of the available total float that may exist within an activity chain of the project schedule, thereby not causing any effect on the contract time. Time extensions will be granted in accordance with the terms of the contract.

Float: Float is not for the exclusive use or benefit of either the National Park Service or the DBC.

Extension of the contract time will be granted only to the extent the equitable time adjustments to the activity or activities affected by the modification, change, or delay exceeds the total (positive or zero) float available on a particular activity.

Known special status species include, the bald eagle, the Atlantic sturgeon, sea turtles and bats among others. The contractor shall employ BMPs that would prevent deleterious materials from entering the York River and nearby streams. Other mitigation measures such as turbidity curtains may be required by fish and wildlife officials.

Visitor Experience: The following mitigation measures shall be incorporated into the action alternatives to minimize the impacts of construction activities on the visitor experience:

Provide “No Fishing” signs and construction fencing to prevent visitor access to the area during construction and revegetation.

Air and Water Pollution Control: Air quality impacts are expected to be temporary and localized. To minimize these impacts, the following actions shall be taken:

To reduce tailpipe emissions, construction equipment shall not be left idling any longer than is necessary for safety and mechanical reasons.

To reduce construction dust, water shall be applied to problem areas. Equipment shall be limited to the fenced project area to minimize soil disturbance and dust generation.

Take all necessary reasonable measures to reduce air and water pollution by any material or equipment used during construction. Keep volatile wastes in covered containers.

Storm Water Pollution Prevention Plan (SWPPP): Submit a SWPPP according to the applicable State Water Resources Control Board's (SWRCB) requirements to the

Contracting Officer for approval. (See Technical Requirements) Before starting construction, the Contractor shall implement the approved SWPPP.

Cultural Resources: We do not anticipate a need for archeological monitoring. If needed, an archeological monitor will be provided by NPS. If archeological resources are discovered at the project site while the archeological monitor is absent, all work in the vicinity of the discovery must stop immediately, and the discovery must be reported to the CO.

2.3.2 Schedule of Values

After contract award and before the Design Meeting, submit a schedule of dollar values based on the

Contract Price Schedule. Breakdown each lump-sum item into component parts of design deliverables or construction work for which progress payments may be requested. The total costs for the component parts of work shall equal the contract line item amount for that lump-sum item. The Contracting Officer may request data to verify accuracy of dollar values. Include mobilization, general condition costs, overhead and profit in the total dollar value of unit price items and in the component parts of work for each lump-sum item, as described below. Do not include mobilization, general condition costs, overhead or profit as a separate item.

Do not break down unit price items. Use only the contract line item amount for unit price items.

The total cost of all items shall equal the contract sum. The Schedule of Values will form the basis for progress payments.

An acceptable Schedule of Values shall be agreed upon by the Contractor and Contracting Officer before the first progress payment is processed. A cost loaded project schedule is an acceptable substitute for a schedule of values in some cases.

2.3.3 Construction Support

Staging Areas

Construction sites will be limited to the smallest feasible area. Ground disturbance and site management will be carefully controlled to prevent undue damage to vegetation, soils, and archeological resources and to minimize air, water, soil, and noise pollution.

Staging is available on paved pullouts at Indian Field creek and Felgate’s Creek. Securing materials and equipment is difficult on paved pullout/parking areas. An additional secure staging area is available at the Ringfield Picnic area approximately 2 kilometers from Felgate’s Creek Bridge. A space near the

Yorktown Maintenance area is available for a construction office or trailer. All vehicles must be parked on paved areas. Construction equipment and material storage shall be located in previously disturbed areas at the Ringfield Picnic area or as approved by the CO and Park staff. All staging areas shall be returned to pre-construction conditions once construction is complete. Standards for this, and methods for determining when the standards are met, shall be developed in consultation with the CO.

Structures: Trailers, Storage, Field Offices, Staging Area and Sheds: Location to be approved by the CO.

DBC's Field Office: Field office shall be structurally sound construction, and weather tight. The location will be determined by NPS prior to issuing a Start Work Notice.

Storage Sheds: If used, provide weather tight sheds or other covered facilities for storage of materials subject to weather damage.

If used, all temporary water, sewer, sanitary facilities and electric utilities, shall be completely removed upon project completion. Remove temporary utility connections.

The location of the Staging Area for construction equipment will require CO approval.

Construction Camp: Establishment of a construction camp will not be permitted.

Construction Zones

COLO 253093B | Page 19 of 35

Construction zones shall be fenced with CO approved construction barrier fencing, plastic or portable fencing, before any construction activity. The fencing shall define the construction zone and confine activity to the minimum area required for construction. All protection measures shall be clearly stated in the construction specifications, and workers will be instructed to avoid conducting activities beyond the construction zone as defined by the construction zone fencing.

Protection of Public: Fence, barricade, or otherwise block off the immediate work area to prevent unauthorized entry. Erect and maintain fencing, barricades, lights, signals, and warning signs in accordance with the most current version of the Manual on Uniform Traffic Control Devices (MUTCD).

The DBC shall protect tree trunks and root systems of trees in or adjacent to work areas.

Special Construction Requirements Weight limitations exist for Colonial Parkway and associated bridges. Check weight requirements prior to shipping materials on these roadways. It is assumed that rock and heavy equipment required to complete the work will be delivered via barge or other seaworthy vessel. Barge access points have been identified by the Army Corp of Engineers and are shown on the design drawings provided.

Parking of Construction Vehicles

Parking of vehicles shall be limited to existing roads, in legally designated areas, and within approved staging area(s).
