About Holladay Engineering Company
Holladay Engineering Company, operating under the trade name Heco Engineers, is a small business civil engineering firm headquartered in Payette, Idaho, specializing in architectural, engineering, and construction services for federal agencies. Established in 1982, the company provides comprehensive infrastructure solutions primarily to the National Park Service, focusing on design, rehabilitation, and maintenance of facilities across national parks, monuments, and recreation areas. As a Subchapter S Corporation registered in the System for Award Management (SAM) since 2003, Heco Engineers has developed a robust portfolio of federal contract work centered on infrastructure improvements, utility systems, and facility management.
Through its prime and subcontract federal awards, Heco Engineers has consistently delivered a wide range of technical services across multiple National Park Service regions. These services include architectural and engineering design for wastewater treatment systems, water infrastructure rehabilitation, HVAC upgrades, facility renovations, fire protection system assessments, structural evaluations, and infrastructure improvements at various national parks and historic sites. The company has performed work for National Park Service regions including Pacific West, Southeast, and Northeast, with contract values ranging from small scoping projects of less than $20,000 to significant design efforts exceeding $600,000. Most of their federal contract awards have not been set aside for specific business categories, demonstrating the company's competitive capabilities across different project types and locations.
Heco Engineers holds a $10 million Indefinite Delivery Indefinite Quantity (IDIQ) contract awarded by the National Park Service in April 2021, which is designated as a total small business set-aside. This five-year IDIQ contract enables the National Park Service to issue task orders for general engineering services nationwide, covering architectural, engineering, and construction services for infrastructure projects. The contract allows for a broad range of services including design, construction, and infrastructure upgrades related to visitor centers, utilities, transportation systems, environmental compliance, historic preservation, and accessibility enhancements. Under this vehicle, Heco Engineers can support the National Park Service's mission by providing expertise in sustainable design, infrastructure rehabilitation, and facility improvements across the agency's network of national parks, monuments, and historic sites.
