Ameren Dorset Roadway Project

Design of a 24-foot wide concrete roadway, which paved the existing gravel road from the east side of Building “E” to the north side of the proposed Fleet Services Garage, a distance of approximately 1,000 feet.  These improvements triggered MSD Stormwater Management requirements.

Tasks included the collection and containment of runoff from the transformer storage area, which involved the design of a reinforced concrete dry detention basin to provide the required channel protection and flood protection volumes, hydraulic design of a spill containment outlet structure, structural design of the basin, 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 north of Building “U.”

Electrical services were provided for the extension of primary services to a new transformer and new lighting along the roadway.

Services provided: Civil and Electrical engineering.


Boeing Building 101 Chilled Water System Upgrade

Conversion of the existing 6800-ton, constant volume chilled water plant located 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 through each chiller. 

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 Building Automation System were designed to replace obsolete hardware and to implement the revised sequence of operations.
