NAVFAC Design-Build Model Request for Proposal - Magazine

A20 GENERAL

RFP Part 3 including the Engineering System Requirements (ESR) provide project specific requirements.  The RFP Part 4, Performance Technical Sections (PTS) provide generalized technical requirements that apply to multiple facility types and include more requirements than are applicable to any one project. Therefore, only the RFP Part 4 requirements that apply to the project and further define the RFP Part 3 project specific requirements are required.

A20 1.1 DESIGN GUIDANCE

Provide the design and installation in accordance with the following references.  This Performance Technical Specification (PTS) adds clarification to the fundamental requirements contained in the following Government Standards.  The general requirements of this PTS section are located in PTS Section Z10, General Performance Technical Specification.

The Designer of Record shall utilize the following UFGS Specifications for the project specification.

Section 31 23 00.00 20, Excavation and Fill

NOTE:  Modify the paragraph below to correspond with the subsurface soils information that is being provided.  If subsurface soils information is to be provided, assure that the information is included in Part 6 of the RFP.

A20 1.3 PERFORMANCE VERIFICATION AND ACCEPTANCE TESTING

Provide verification of satisfactory construction and system performance of the basement via Performance Verification Testing, and by field inspection, as detailed in this section of the RFP.

A20 1.3.1 Earthwork

Perform quality assurance for earthwork in accordance with International Building Code (IBC) Chapter 17 and UFGS Section 31 23 00.00 20.  If a registered Professional Engineer is required to provide inspection of excavations and soil/groundwater conditions throughout construction, the Engineer must perform pre-construction and periodic site visits throughout construction to assess site conditions.  The Engineer, with the concurrence of the Contractor and the Contracting Officer,  must update the excavation, sheeting, shoring, and dewatering plans as construction progresses to reflect actual site conditions and must submit the updated plan and a written report (with professional stamp) at least monthly informing the Contractor and the Contracting Officer of the status of the plan and an accounting of Contractor adherence to the plan; specifically addressing any present or potential problems.  The Engineer must be available to meet with the Contracting Officer at any time throughout the contract duration.  Provide the services of the Engineering at no additional cost to the Government.

NOTE: NAVFAC has made every effort to use commercial standards in the PTS Sections. If project requirements dictate the use of a UFGS Section as a standard, add a paragraph here listing the required UFGS Section. State in the paragraph that the DOR must edit this UFGS Section in accordance with PTS Z10 and submit it as a part of the design submittal.
