RFIs to this solictation have been added Railing Specifications, 13 SEP 19 - Section 05-52-00 Metal Railings Part 1 General, 1.2 Administrative Requirements, 1.2.1 Preinstallation Meetings - Within 30 days of contract award, submit fabrication drawings to the Contracting Officer for the following items: a. Steel Railings and handrails; b. Anchorage and fastening systems. The original solicitation Section 11 states The Contractor shall begin performance within 5 calendar days and complete within 45 calendar days after receiving award.

Government Response: The Contractor shall begin performance within 5 calendar days and complete all work and clean up within 45 calendar days after receiving award due to all fabrication being done on site and no drawings being submitted prior to work beginning.

Is there a new completion timeline based upon the drawings and anchorage and fastening systems submission requirement in the Railings Specifications document? If so, what is the new timeline?

Government Response: There will be no drawings and anchorage and fastening systems submission requirement for this contract. All work shall be fabricated on site to match any existing handrails.

What is the expected timeline for government approval of the Fabrication Drawings and Anchorage and Fastening Systems product data?

Government Response:There will be no drawings and anchorage and fastening systems submission requirement for this contract. All work shall be fabricated on site to match any existing handrails. Railing Specifications, 13 SEP 19 - Section 05-52-00 Metal Railings Part 2 Products, 2.2.5.1 Steel Handrails Provide steel railings of 2 in nominal size, hot-dip galvanized. Part 2 Products, 2.2.3 Steel Pipe - Provide pipe conforming to ASTM A53/A53M...(Schedule 40)

Government Response: Steel Pipe - Provide pipe conforming to ASTM A53/A53M (Schedule 40) Shall be used for construction of metal handrails.

Government Response: Will be no government provided dimensioned elevation drawings showing the changes in elevation across the installation site with finished concrete elevation due to all fabrication being done on site. Alternate line item for bid.

Would it be in the best interest of the government to offer an either/or bid item for shopfabricated and galvanized or fabricated in place and painted handrails? The existing pipe railings at the site are 2" OD fabricated in-place painted structures. Shop fabricated, galvanized handrails as specified in the amendment would require significantly more time and expense than the originally solicited items. Fabricated in-place, painted handrails conforming to 29 CFR 1926.502 Fall Protection Systems Criteria and Practices would match the existing handrails at the site, could be completed within the original 45 day time period and offer a substantial cost savings to the government.

Government Response: Fabricated in-place, painted handrails conforming to 29 CFR 1926.502 Fall Protection Systems Criteria and Practices is what the government is asking for on this contract.
