About this file

Written by GovTribe AI · Apr 22, 2024

This document contains the drawings and specifications for the HVAC & Electrical Upgrades for Sunnyside Elementary School in Dinwiddie County, Virginia. The project scope generally includes the removal and replacement of mechanical equipment serving the gymnasium, the removal and replacement of corridor ceiling grid and acoustical ceiling tiles, and the installation of electrical panels and infrastructure for future electrical connection to rooftop mechanical equipment. The work is to be performed during the summer months while the building and site remain open, operational, and accessible to the public and staff during regular business hours. Partial occupancy by the Owner is anticipated, and the Contractor must cooperate to minimize conflicts and facilitate continued use of the facilities.

The document provides details on the applicable building codes, construction types, occupancy classifications, and means of egress requirements. It also includes information on asbestos and lead containing materials, and requirements for contractor coordination with the Owner and the public during construction. Pricing, funding sources, and set-asides are not addressed in the provided documents.

GYMNASIUM VENTILATION CALCULATION

NOTE: OUTSIDE AIR FLOW RATES AS SCHEDULED ARE GENERALLY CALCULATED VIA THE ASHRAE VENTILATION RATE PROCEDURE (VRP). ANY VENTILATION EXCEEDING THE VRP REQUIREMENT IS DUE

TO A POSITIVE SPACE PRESSURE REQUIREMENT. WHERE EXISTING ELECTRICAL CAPACITY OR

ADAPTER CURB SIZE REQUIREMENTS LIMITED THE AMOUNT OF OUTSIDE AIR POSSIBLE, VENTILATION RATES ARE IN COMPLIANCE WITH THE INDOOR AIR QUALITY (IAQ) PROCEDURE, WHILE MAINTAINING COMFORTABLE SPACE TEMPERATURE AND HUMIDITY LEVELS IN COMPLIANCE WITH ASHRAE 90.1.
