MECHANICAL & ELECTRICAL SERVICES PROJECT SCOPE OF WORK

This project entailed the renovation of an existing 22-year-old data processing center electrical and mechanical infrastructure. This facility included a critical link in the communications network of both US West and AT&T. The electrical design required replacement of the two existing 1675 kW turbine generators. Two 1250 kW and two 1750 kW diesel generators were installed with a new switchgear and modifications to the existing electrical system to provide for additional redundancy.

The mechanical design involved extensive modification of the central plant. This project included HVAC installation of a new chilled water riser for the five-level data processing area of the facility, redesign of the primary chilled water loop of the central plant, installation of new central plant controls, upgrades to the existing cooling towers, new plate and frame heat exchangers, chillers, and computer room mechanical systems.

BACKGROUND

The principal activities of the group provide local telephone, long distance, wireless and data services. Qwest Communications International Inc. acquired US West.

OBJECTIVES

To be competitive in their fast growing industry.

MECHANICAL CONSTRUCTION SOLUTIONS

The design effort required extensive fieldwork to verify existing conditions as well as coordinate and schedule work with the facility operating personnel and local utility company. Trautman & Shreve took the lead in developing 3-D CAD fully coordinated drawings. These Building Information Modeling (BIM) diagrams included schematics for structural, electrical, fire protection, mechanical and plumbing systems. In doing so, Trautman & Shreve identified architectural, structural, and other discipline conflicts to coordinate proper construction documentation prior to construction. This provided significant efficiencies in the field through a maximized fabrication process while eliminating the need for rework.
