We are federal construction experts who specialize in the performance of high-volume IDIQ contracts. Our experience performing more than 3,000 stand-alone and task order construction projects had led us to develop a diverse foundation of project experience; from the removal and mitigation of bird nests from 40 plus buildings at Fort Hood, to the construction of a new 83,500 square foot/$35 million battle command training center at Fort Carson; and performance of a Job Order Contract at Washington State University. 
NASCO has conducted large-scale operations supply support and services for some of the largest projects in the world. We identify possible short-term as well as long-term savings to help safely maximize our customer’s resources, production, and profits.
