MEP Designs, Inc.  is  a  leading  professional  engineering  firm  and premier provider of mechanical, electrical, and plumbing engineering and consulting services in the mid-Atlantic region. We provide engineering services for both new and renovation projects in a broad range of applications including commercial, government, institutional and multi-family residential buildings.

Compounding Pharmacy

Fairfax, Virginia

Permit plans for a new compounding pharmacy in Fairfax is already in the city for review.  The team in MEP Designs provided engineering services for the 2,300-SF space.  The new pharmacy will have compounding labs in compliance with various levels of The United States Pharmacopeia compounding standards (USP795, USP797, and USP800).

Our engineers worked closely with the owners, architect and contractor to ensure performance criterion are met.  Design of compounding labs require extensive levels of air-changes per hour, while maintaining specific levels of room-to-room pressurization, according to the lab classification, e.g. sterile vs non-sterile, and hazardous-compounding vs non-hazardous-compounding.

MEP Designs team developed a niche for the design of electrical systems, SCADA and controls for municipal pump and PRV stations.  Our engineers recently completed the engineering design of the following projects for various clients and prime engineering firms:

  • Potomac Yard Pressure Zone (PRV) Station for Virginia American Water – Alexandria Main Service Area.
  • Brickyard Pump Station for Prince William County, Virginia
  • Beaumeade PRV Station for Loudoun County, Virginia

In addition to electrical engineering, our engineers provided process flow chart, PLC Controller input/output points list, conduit routing details, control panels details, short circuit and arc-flash analysis, and mechanical ventilation analysis and design.
