- Description
- DESC: 1. This is a modification to Solicitation Number SOL03000017, posted in FedBizOpps on 1 May 2003. The proposal closing date and time is extended to Friday, June 6, 2003 at 4:00PM EST. 2. Due to the heightened level of security at the FCC 12th Street location, all proposals must be delivered to the FCC Warehouse, 9300 Hampton Drive, Capital Heights, MD 20743, Attn: JoAnn Summers by 400PM EST, 6 June 2003. 3. Proposals are to be submitted in the following format: One (1) original technical and cost proposal and three copies of the technical proposal without cost. 4. The following questions were submitted by a vendor in response to Solicitation Number SOL03000017. Q ? Please provide the ?R? value of the existing insulated siding on the building exterior. If this is not obtainable, please provide the desired ?R? value for the new construction. A - The insulated exterior wall panels on the existing building were replaced in the early '80s, and we have been unable to locate any records of that contract. We have no idea of the actual R value of the panels. We know only that they are 2"-thick steel-skinned panels filled with insulating foam. We specified in the SOW that the new enclosure be insulated in accordance with the prevailing local commercial code for this type of structure. Vendors engaged in commercial construction should contact the appropriate office in Howard County to determine the code-required insulation value. Q - Are there specifications for the original construction of the existing building? If so, please provide. A - We have one complete set of the original construction drawings of the existing building... no specifications document. Q - Is there a ?geo-technical report? available at the site? Is there any available information concerning the water table? Is the site in a ?flood plain?? A - There exists no "geo-technical report" for the site. We know that the site is not in a flood plain, but we have no specific information on the water table (although we do know that there have been no water table problems in the 29 years since the existing building was built). The grade level existing building is also 6' to 8' above the grade at the septic drain field. This would indicate that the water table is not a concern. The drawings for the existing building contain the notation: "Soil Boring Data indicate safe soil bearing to be 3000 P.S.F." If a vendor feels that additional soils testing is necessary, then that should be a part of the proposal. Q - Please indicate what date the owner will have ?Miss Utility? inspect and mark the site. A - Miss Utility has been contacted and all utilities will be marked by 5/29. Vendors were apprised of approximate locations of buried lines during the site visit. Q - The time specified in the bid documents only allows 90 days. This is not sufficient to hire an architect/structural engineer, prepare construction drawings showing electrical, mechanical, concrete, structural building, soils testing, fabrication, installation, etc. of just the ?general construction?. Time should be allowed for a genuine and properly constructed RF shield and anechoic treatment. This is not the type of project that should be hastily constructed. A period of 120 days as a minimum to a more paced schedule would allow 150 days. This is not excessive for all that is required to build this type of facility. A - The solicitation specifies a completion schedule of 16 weeks (112 days) after date of contract, not 90 days. This was based on estimates of 12 to 14 weeks construction time.{END OF CHANGES} This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6 as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued.

Commercial Items (Nov 1999) Incorporated by Reference FAR 52.212-2, Evaluation-Commercial Items. The Government will award a contract resulting from this solicitation to the responsible offeror whose offer conforming to the solicitation will be most advantageous to the Government, price and factors considered. Evaluation critera can be found at http://www.fcc.gov/omd/contracts/pre-awardA complete copy of the provisions at FAR 52-212-3, Offer Representations and Certifications-Commercial Items shall be included with the Offeror?s RFP, FAR 52.212-4 Contract Terms and Conditions-Commercial Items, and FAR 52-212-5, Contract Terms and Conditions Required To Implement Statues Or Executive Orders-Commercial Items. The Federal Communications Commission Laboratory, 7435 Oakland Mills Road, Columbia, Maryland 21046., seeks to acquire a 3-meter, semi-anechoic electromagnetic compatibility (EMC) test chamber and associated equipment to be finished and installed adjoining its existing main building on a turn-key basis. Construction of an enclosing structure with HVAC and electrical distribution system is included as part of the contract scope. Facility will be used for radiated EMC limits compliance testing and both radiated emissions and immunity measurements associated with research projects. Finished facility is to be tested for compliance with ANSI C63.4, IEC 61000-4-3, and MIL-STD-285 standards. FCC envisions needing this equipment by October 2003 for use in November 2003.
