About this file
This document is a Certified Testing and Balancing Report for the United States Coast Guard Academy Water TAB project. It includes instrument calibration details, a glossary, and remarks related to the testing of water pumps and heat exchangers. The report presents the measurements and data obtained in accordance with NEBB standards for the project's HVAC systems.
The related federal contract opportunity is for a Design/Build project to replace the existing steam and condensate piping throughout the U.S. Coast Guard Academy campus in New London, CT. The solicitation is posted exclusively for contractors on the current DHS/USCG National Multiple Award Construction Contract III (NMACC III- Pool 1). The project requires replacing steam and condensate piping, as well as hot water supply and return piping within various mechanical rooms. The selected contractor will provide all labor, material, equipment, and related services for the design-build effort.

Measuring in Velocity (referencing Air Outlet Test Sheets and Grille, Register & Diffuser Test Sheets):
Notes
Ak Factor indicates actual area of registers, following multiplying the Ak by the area equals the actual free area;
If codes are not listed here, please reference design drawings.
Measuring with Flow Hood (referencing Air Outlet Test Sheets and Grille, Register & Diffuser Test Sheets):
Registers, diffusers and grilles are read directly in CFM. (Report program indicates 1.00 in Ak Factor column.)
therefore CFM is calculated and based on this factor (FPM x Ak).
