Collaborative Environment with Robust Communication

EDM partners with industrial, manufacturing and process plant clients across the US, providing services for projects ranging in construction value from $100,000 to over $10,000,000. We approach each project from the client’s point-of-view, so that we clearly
identify goals, objectives and challenges, then continue with ongoing communication at each step until completion of the project is to the
client’s satisfaction.

Ameren | Dorsett Roadway | St. Louis, MO

This project entailed the design of a 24-foot, 1000-foot long concrete roadway.  These improvements triggered MSD stormwater management requirements. Tasks included collection and containment of runoff from the transformer storage area, which involved the design of a reinforced concrete dry detention basin for the required channel and flood protection volumes; hydraulic design; outlet structure and catwalk, and design of storm sewer system. EDM also designed flow diversion structures and storm sewers necessary to balance the disturbed area flow to the new reinforced concrete surface sand filter, enclosing existing swales. Electrical services were provided for a new transformer and new lighting along the roadway.

Boeing | Building 101 Chilled Water System Upgrade | St. Louis, MO

Conversion of the existing 6800-ton, constant volume chilled water plant in Building 101 to variable primary flow.  New differential pressure sensors were added to measure the pressure drop across each chiller’s evaporator to calculate the flow rate. New variable frequency drives were specified to control seven primary chilled water pumps and seven secondary chilled water pumps.  A comprehensive survey of the connected equipment to the plant was performed to document the existing control valves.  All existing 3-way DDC valves were replaced with 2-way DDC valves and the bypasses on existing 3-way pneumatic valves were closed.  Major upgrades to the existing Andover BAS were designed to replace obsolete hardware and to implement the revised sequence of operations.
