Overview

The Mission Lane project involved a comprehensive upgrade of the mechanical, electrical, and plumbing (MEP) systems of an existing building. The work focused on transforming an industrial property into an office for a financial services firm in the Scott’s Addition neighborhood of Richmond.

Mechanical

The mechanical scope included the installation of a high-efficiency rooftop unit which integrated economizers to optimize energy use. Split systems were installed in specific zones such as conference rooms and workstations to provide localized zoning. The ductwork was insulated to R-8 standards in unconditioned spaces, with sound dampening return elbows at private offices.

Electrical

The electrical distribution system was designed to ensure efficient power delivery throughout the building. The system begins with a 400A main distribution panel (MDP), fed by a 277/480V three-phase service from the utility. This panel distributes power to two main transformers, each stepping down the voltage to 208/120V. The transformers, rated at 112.5 kVA, supply power to several subpanels located across different areas of the building.

Plumbing

The plumbing system included a 2-inch main water supply line, supported by a tankless water heater with a capacity of 199,000 Btu/h, ensuring a reliable hot water supply. PVC waste and vent piping were installed for drainage, along with backflow prevention devices to protect the potable water system. ADA-compliant fixtures, including water closets, urinals, and lavatories, were installed to meet accessibility requirements.
