U-66 Exterior Envelope Replacement Design Consultant

23-58220-B U-66 Exterior Envelope Replacement Design Consultant

General Project Overview

U-66 is the home of our Trisonic Wind Tunnel used by Aerospace Research Centre to conduct research in design, manufacturing, performance and maintenance of air and space vehicles. The 1.5 m trisonic wind tunnel is a pressurized, intermittent-flow wind tunnel capable of providing subsonic, transonic and supersonic flows, Mach 0.1 to 4.25.

The first portion of the U-66 building was originally built in 1958 and completed with misc. building additions, up to approximately 1989. There are various building envelope materials used in these additions. The exterior envelope of building U-66 is predominantly clad with a stucco wall finish. The stucco finish is in poor condition and has deficiencies including cracking, staining, and deteriorated areas of stucco in several areas. An exterior insulation and finish system (EIFS) wall system is located at the north side of the building, refer to Key Plan - Area “D” & Area “E2” below. There is a separate project in progress for a building extension to house a new compressor. It is anticipated that this extension will be located on the North side of the building adjacent to Area “E2”.

The exterior finishing of this building requires remediation. Specifically, the exterior of the building noted in dotted blue line below defines the current scope for this project. The main portion of the area requiring remediation consists of structural steel filled with terra cotta brick and precast panels, complete with a stucco finish on the exterior. Multiple previous patches and repair work were evident throughout the wall assembly.

Project Description The exterior building envelope at U-66 requires remediation/replacement. This RFP incorporates four main sections of scope, Feasibility Design, Detailed Design, Services during Tender and Services during Construction of the exterior envelope outlined in the Key Plan in blue above. Asbestos was found in most of the existing construction materials therefore this must take this into consideration when reviewing and selecting options for reinstatement. Existing building documentation will be provided to support this scope, such as but not limited to the scanned original construction drawings, and site-specific designated substance report, etc. Final bilingual construction documentation to be ready for public tender by October 24th, 2025. In order to meet the objectives outlined in this Request for Proposal (RFP) for Engineering Services, Consultants are to develop and provide complete, clear, and effective project documentation in accordance with requirements outlined in this project specific RFP document, the NRC Construction Documentation & Deliverables Manual, and the NRC Engineering & Construction CAD Standards.
