STRUCTURAL SYSTEMS NARRATIVEThe Stabilization Project, designed by Bohannan Huston, is included in the Construction Document set titled DACC Building 341 Building Renovations, designed by Willians Design Group.

Based on an evaluation of visible damage that has appeared both inside and outside the 1981 building addition to the original 1976 DACC Building 341, it was determined that the entire addition is settling in relation to the original building. The results of a geotechnical investigation recommended the installation of helical piers under all bearing walls in the addition to prevent additional settlement. Settlement damage that has already occurred will require repair. Damaged areas include settlement cracking visible on the interior and exterior of the building, and damage to bearing locations of the existing bar joist framing into the common wall between the original 1876 building and 1981 addition.

The project must be constructed when the classrooms have been evacuated for construction and coordinated with the upgrades required in the rooms. These classrooms and laboratories are very busy and they must be returned to the school in a timely manner according to the project schedule.

The capacity of existing panels is assumed to be adequate. However, it is expected that existing panels will not have enough breaker spaces. We expect to add 120V circuit panels to feed new outlets in remodeled classrooms. New circuits are needed in the labs for 220V loads. This is an area that new panels may be needed as well.


ELECTRICAL DISTRIBUTION – HVAC New load will be added because of new HVAC ventilation and new exhaust systems. New circuits will be added as needed. New panels and new feeders will be added as needed. LIGHTING In areas of remodel and new work, existing lighting will be replaced with new light fixtures. Most of the new lights will be LED. The new lighting in the General Classrooms will be with 2 x 4 recessed LED light fixtures. The computer classroom new lighting is the only planned area with new fluorescent lighting; this will be with pendant hung direct/indirect LED. The wall mount switches will be replaced with bi-level low voltage switches tied to new occupancy sensors. The occupancy sensor system shall be Watt Stopper or equal. Emergency and exit lighting will be added as needed to meet code. Provide power and control to the new solar tubes where installed. DATA WIRING Data drops will be added as needed. Per NMSU standard the cable will be provided to the contractor for installation by him, but termination will be DACC/NMSU.
