City Public Service (CPS) implemented a project to engineer, procure, construct, own and operate a new nominally rated 750-MW coal-fired electric power generating unit at its existing Calaveras Lake site in San Antonio. The project is known as JK Spruce Unit 2.

The project was completed on a total design-build basis as defined by Texas regulations. The bid documents were issued in summer 2004.

Burns & McDonnell’s scope of services included initial planning, design-build contract development, design-build contract enforcement and construction monitoring. As part of the initial planning phase, Burns & McDonnell prepared studies to evaluate the existing facilities and to assess the feasibility of CPS directives. Scope of the studies included mechanical assessments of flue gas desulfurization (FGD) technologies, FGD auxiliaries, fire water pumps, service water pumps, condensate polisher and demineralizer. Electrical assessments included the medium voltage system and utilization of variable frequency drives (VFDs). Material handling assessments included the coal handling system and limestone unloading system. Information gathered during the initial planning phase was used in developing the design-build contract.

The 750-MW coal fired generating facility was engineered and constructed by others. Burns & McDonnell defined the design and construction criteria within the design-build contract. This multiple-volume document included the technical and commercial terms of the contract.  Enforcement of the contract included review of the design-build design and monitoring of construction activities.
