About this file
This document is an Architects Supplemental Instructions (ASI) Number 001 issued on October 1, 2026, for the Rosebud Agency Boiler & HVAC System Design for Building #1004, a Bureau of Indian Affairs project.
The ASI mandates revisions to the Dedicated Outdoor Air System ductwork on Mechanical Sheets MH101 and MH102. Currently, 74 ventilation air connections route from the supply main directly to room-located variable refrigerant fan coils; this configuration will be modified so that 70 connections redirect from direct unit connections to sidewall grille connections, while four basement areas will be ducted to supply diffusers in their respective rooms. The ventilation air will no longer connect to the variable refrigerant blower coil but instead terminate at a sidewall grille, which will discharge all required ventilation air into the room. The sidewall grille must be positioned on the opposite side of the corridor wall, away from the transfer grille to ensure proper air circulation and mixing. Revised mechanical sheets MH101 and MH102 reflect the new ventilation air ductwork routing, and Sheet MH702 is submitted with specifications for the double deflection sidewall grille required for this modification. The ASI is distributed to the file and the Owner/Agent (Bureau of Indian Affairs), with copies directed to the BIA Contractor, and was issued by Bradley J. Kennedy, a professional mechanical engineer registered in Nebraska.

ARCHITECTS SUPPLEMENTAL INSTRUCTIONS (ASI)
ASI NUMBER: 001
DATE: 10/1/2026
PROJECT: Rosebud Agency Boiler & HVAC System Design Building #1004 OWNER/AGENT: Bureau of Indian Affairs
CONTRACTOR:
DISTRIBUTION: X File X Owner/Agent (BIA) By BIA Contractor
1. Original Mechanical Sheets MH101 and MH102 need the Dedicated Outdoor Air System Ductwork changed. Replace the current connection to the variable refrigerant flow equipment with the following:
Mechanical sheets MH101 and MH102 will revise the ducting of ventilation air into each office. Currently, 74 connections show ventilation air ducted from the supply main to the room-located variable refrigerant fan coil. These connections will change: 70 of those connections will move from direct connections at the unit to a sidewall grille connection. Four areas in the basement will be ducted to supply diffusers inside their respective rooms. The ventilation air will not connect to the variable refrigerant blower coil as originally shown. Instead, the new 4” round ventilation duct will terminate at a sidewall grille. The sidewall grille will discharge all needed ventilation air into the room. The sidewall grille must be located on the opposite side of the corridor wall, away from the transfer grille to maintain good air circulation and mixing. Refer to revised sheets MH101 and MH102 for new routing of ventilation air ductwork. Sheet MH702 is also being submitted with the proper double deflection sidewall grille to be used for this change.
