RFI #27: The contract documents reference spray-applied fireproofing in multiple locations, including Specification Sections 01 45 29 Testing Laboratory Services, 01 45 35 Special Inspections, and 05 12 00 Structural Steel Framing, which references Section 07 81 00 Applied Fireproofing. However, Section 07 81 00 Applied Fireproofing does not appear to be included in the issued specification set, and the Contractor has been unable to identify on the drawings where spray-applied fireproofing is specifically required for this project.

Please clarify whether spray-applied fireproofing is required as part of the base scope of work for this project.

If required, please identify the applicable locations, extent of work, required fire-resistance ratings, and provide the governing specification section. If not required, please confirm that references to spray-applied fireproofing in the contract documents are not applicable to this project.

Reason for RFI:

The contract documents contain references to spray-applied fireproofing inspection, testing, and related work, but do not include the governing installation specification section or clearly identify where such work is required on the drawings. Clarification is required to determine whether spray-applied fireproofing is part of the project scope and to accurately account for associated materials, labor, inspections, and cost.

Reference: Specification Sections 01 45 29 Testing Laboratory Services; 01 45 35 Special Inspections; 05 12 00 Structural Steel Framing; Division 07 Table of Contents; Drawings Drawing: N/A Specification Section: Not specified

VA Response: Spray-Applied fireproofing can only be used on structural steel members, monokote. If any existing monokote is damaged or replaced during construction, then the General Contractor shall notify the COR for resolution. All penetrations shall be done in accordance with Specification, 07 84 00, Firestopping.

RFI #28: Specification Section 02 21 13 includes requirements for site surveying and layout services. The scope of work for this project appears to include limited exterior site work, with most work occurring within or directly adjacent to existing structures.

Please clarify the extent of survey services required for this project. Specifically, confirm whether full site surveying services are required, or if layout may be performed based on existing structures, control points, and field verification for the limited site work associated with this project.

Additionally, please confirm any requirements for certified survey, control points, or as-built survey documentation.

The project includes limited site work, and the contract documents do not clearly define the required level of survey services. Clarification is required to determine the appropriate scope of survey and layout services and to accurately account for associated cost and coordination.
