TECHNICAL PROVISIONS (080304)

PART 1 - GENERAL - This project is a Requirements Contract. There is no specific work attached to this document. This document establishes line item cost data from which to build future projects for award to the successful bidder for construction.

1. PROJECT LOCATION: All work under this project will be performed on Elmendorf AFB. Work in limited access areas will be stipulated in the Delivery Order (DO).

2. NOTIFICATION OF WORK START: The Contractor shall provide 10 working days advance notice in writing to the Contracting Officer in Building 10480, Elmendorf AFB prior to beginning any work under the scope of this project. The Contractor shall notify all affected organizations such as Fire Department, Security, and building occupants of the proposed work schedule. The contractor shall then re-notify building occupants at 7-days and 3-days prior to work affecting individual units.

2.1 Coordinate with appropriate utility locating agencies, including base communications cable maintenance (Item 1 through 18) of 3rd Wing Form 3 (Base Civil Engineer Work Clearance Request). Form 3 will be provided to the contractor during the pre-construction meeting. Contractor shall complete and follow all instructions on Form 3 before start of work in accordance with Wing Instructions (3 WGI 32-1007) “Safeguarding Utilities from Damage”. A copy of the Wing Instructions will be available to the contractor during the pre-construction meeting.

2.1.1 The contractor shall fully coordinate and schedule any building utility shutdowns that may be required with the appropriate shops and facility occupants upon award of a DO. A 10 day advance notice is needed to give the appropriate shops sufficient time to prepare the respective facility for utility service shut off and to notify base or other contractor personnel of utility outages prior to a scheduled outage.

2.1.2 Contractor shall maintain all utility locates in the field once they are initially marked by each utility agency. If the markings are damaged the contractor shall request new locates and shall give the locating agency 48 hours to perform the new locates. Expenses for time and materials to perform repeat locates shall be borne by the contractor, unless otherwise approved by the approving officer. Cost to do the repeat locates will be deducted from the final invoice. Cost will be calculated using the average shop rate of $35.00 per man-hour. In cases where utilities were marked late in the year and operations had to be shut down for winter, marked utilities will still have to be maintained by the contractor by placing stakes or transcribing the marks on a drawing. When construction resumes, contractor shall re-mark the site and may request verification of utility locations at no cost to him (Off Base utility locate agencies might request additional cost for repeat locates).

2.1.3 Clearance request is not valid unless signed by the approving officer. Approving officer will not sign until all locates are marked and all utility locating agencies’ signatures are on the form. Excavation work shall commence within 30 days after the approving officer’s signature, otherwise clearance request is invalid and a new request is required. Notify Contracting Officer immediately if new utilities were installed by others and not marked after all initial locates are made.

2.1.4 Any work conducted off Elmendorf AFB property requires the coordination of affected Base agencies. Any off Base work clearance forms shall also be submitted to the Contracting Officer.

2.1.5 The contractor is considered a “construction agency” for compliance with the provisions of WI 32-1007.
