Just before the beginning of the 1999 cooling season the General Services Administration verified that the Air Handling Units and duct system serving approximately 150,000sf of the 400,000sf facility were contaminated with asbestos. Building occupants included the US Weather Services Satellite Operations Command Center and over 8,000sf of mission critical Cray super computers. These

computers make up the worldwide extreme weather tracking system used to predict violent, life-threatening storms. An evaluation of the costs to relocate these systems quickly totaled above $10 million. It was immediately apparent that the building occupants could not be relocated to a different location.

Summer Consultants, Inc. and Welsh and Rushe, Inc. were brought in to accomplish the near impossible, provide cooling capability to this facility before the cooling season began in five weeks. Study and design services began immediately, and within days Welch and Rushe, Inc. personnel were on site sketching sheet metal work needed. During the entire process senior personnel from Summer Consultants, Inc. and Welch and Rushe, Inc. worked closely with building management to answer building occupants' concerns. There was also significant planning and coordination to ensure future renovation of the facility could occur as part of the building master plan.

The team's solution to this problem was to decontaminate the existing Air Handling Units and erect a temporary, external duct system. Design and construction were performed nearly simultaneously; designs for an area were completed on a Monday and construction would begin on Wednesday. Working days, nights and weekends the team of Summer Consultants, Inc. and Welch and Rushe, Inc. designed and installed, within budget, a $1.2 million working solution before the 1 May deadline. All without any major disruption to the building occupants.

What the solution may lack in aesthetics it makes up for operational capability. The building manager receives fewer complaints with the replacement system than with the previous system.
