NAVFAC Design-Build Model Request for Proposal - Test

A10 FOUNDATIONS

SYSTEMS REQUIREMENTS
FOUNDATIONS TEMPLATE 12/08
 
Instructions for using this template: There are template files for each UNIFORMAT Level 2 Group Elements. This template is for Group Element A10-FOUNDATIONS. Text such as this is hidden text that will not print when the hidden text box in "Print/Options" is un-checked.
 
The Structural Team Member must edit this template for the requirements of the project and wherever brackets [ ] appear.  The Designer shall use UFC 3-300-10N when determining project requirements.
 
The SYSTEMS REQUIREMENTS are intended to define items that are required throughout the facility. . Room-specific requirements are defined in the ROOM REQUIREMENTS section. Coordinate with the lead programmer for ROOM REQUIREMENTS. Delete all elements that are not required for the project. If additional elements or sub-elements are required for the project that do not appear in the template, refer to the NIST UNIFORMAT II publication for additional building element numbers and descriptions.  The Uniformat II Work Breakdown Structure can be found at www.wbdg.org/ndbm/. Coordinate with the PERFORMANCE TECHNICAL SPECIFICATION SECTION A10 (Section A10) to ensure that performance requirements are provided for all of the Building Elements listed here and that paragraph numbering matches
 
There may be rare occasions when prescriptive specifications may either be edited and included in Part 5 of the RFP or required in Section A10 to be edited by the Contractor’s Designer of Record.  In both cases, the Engineering Systems Requirements (ESR) must include references to these documents.

SYSTEM DESCRIPTION

Provide the building foundation system in accordance with UFC 3-300-10N, Structural Engineering.  Foundation shall be designed to suit subsurface conditions, and shall be capable of transmitting all building loads to the ground.

NOTE:  If Section B10 Superstructure, is not provided as part of this Request For Proposal, delete the following paragraph and provide any required structural design criteria in the subsequent paragraphs.

[See Section B10, Superstructure, for additional loading criteria.]

NOTE:  Delete the following paragraphs if this information will be provided in Section B10, Superstructure.  Provide information for special live loads, concentrated loads, and extraordinary events (e.g., terrorism threats, accidental blast).  Normally, special loads and extraordinary events are not required and the following paragraphs will be deleted.

[In addition, design the structure in accordance with the following loading criteria:

[Live Loads

[Live loads for occupancies or uses not provided in UFC 3-310-01 shall be as follows:

Occupancy or Use: _______________________ 

Uniform Live load: ____________ psf.]

[Concentrated Live Load: ______________lbs.]

[Live load that differ from the minimum live loads provided in UFC 3-310-01 shall be as follows:

Occupancy or Use: _______________________ 

Uniform Live load: ____________ psf.] 

[Concentrated Live Load: _______________lbs.]

][Extraordinary Events

Design the structure to withstand the effects of the following extraordinary (i.e. low probability event: [______________________].

NOTE:  Delete the following paragraphs if this information will be provided in Section B10, Superstructure.  Provide wind exposure and Importance Factor information if the contractor cannot be expected to be able to obtain this information from other sources.

][Importance Factors

Use Occupancy Category [I] [II] [III] [IV] [V] in Table 1 of UFC 3-310-01 for determining Importance Factors for seismic, snow, and wind design.  The corresponding Seismic Use Group is [I] [II] [III] [IV].

][Wind Exposure

Wind design shall be based on Exposure [A] [B] [C] [D].]

NOTE:  Delete the paragraphs below if no subsurface soils information is being provided.

[Government Provided Subsurface Information

Subsurface soil information[, including a geotechnical report ][and pile driving analysis] [from projects immediately adjacent to the project site], are included in other portions of this RFP.  

Any included subsurface data and information is only for the Contractor’s information and is not guaranteed to fully represent all subsurface conditions.  The Government shall not be responsible for any interpretation or conclusion by the Contractor drawn from the data or information.

Any geotechnical report included with site investigation data is provided only to better convey data (boring logs, testing, etc.) or to document observed site conditions.  The assumptions, analysis, and recommendations of the accompanying report were developed for preliminary planning purposes only and may not be based upon present project requirements.  Requirements stated in Parts 3 and 4 of the RFP take precedence over any content of any included geotechnical report.

The Contractor is required to retain a geotechnical engineer experienced and licensed in the geographic region of the project to interpret the provided data as related to his design concept and develop requirements for bidding.  Additional requirements for the geotechnical design of this project are provided elsewhere in this RFP.

Minor variations between borings should be anticipated.  The Contractor shall bear all costs associated with the site preparation and actual foundation except as allowed by the Contract Clause FAR 52.236-2, "Differing Site Conditions".  The Contractor’s Geotechnical Engineer shall perform additional subsurface investigation as required to adequately determine all applicable geotechnical factors including the type and capacity of the project foundation(s).  The Contractor’s Geotechnical Engineer shall consider the provided information and any additional information obtained and prepare a report as described in other portions of this RFP.]
