223 29th St Historic Apartments

MEP Design for a historic woman's home into an apartment building.

Overview

8,000 Sq ft historic rehabilitation of an a former women's seminary. The project located in Newport News, Virginia, includes a basement and three above grade levels. Team members included ProVost Construction as the GC/Developer and Archsmith Studios as the architect.

Electrical

The electrical design included a 1000 amp, single phase service terminating on a standard meter center with service disconnects (125-150 amps) protecting the feeders extending to each unit's main lug load centers. The main service is provided with a house panel for house loads and peripheral site branch fixtures as needed.

Plumbing

The plumbing design includes a 1 1/4" main domestic water line from a 1" water meter. Hot water is provided by a central tankless water heater manifold and recirculation system. The drainage system is a simple PVC system where all units collect and eventually discharge to the sewer with a 6" main. The venting strategy for each bathroom is handled with wet venting, and kitchen sinks are vented with air admittance valves. Condensate is routing to storm per HRSD requirements.

Mechanical

The mechanical design includes a simple split heat pump for each unit ranging in tonnage between one and three tons depending on load calculations. Each indoor fan coil unit has electrical strip heat for extreme cold months. The strip heat also counteracts comfort issues arising when running defrost cycles during winter months. The bathroom exhaust is collected and discharged to the roof.
