Precision As-Builts (formerly Helihawk Associates) was founded in St Louis in 1999 and has since grown into a firm of 25 talented surveyors and professionals who believe in providing unparalleled precision in their work. Our corporate headquarters is now located in Colorado Springs, CO. Precision's service area covers all 50 states and beyond. We have traveled as far as Guam (3 times) to perform surveys for national retail clients that love our work so much, our surveyors were literally sent to the other side of the world to do what they do best! Over 24 years of service we have created 12,500+ architectural as-built drawings covering all building types and sizes. Contact us to learn what we’re able to accomplish.

In 1999 Bob Missroon, the founder of Precision As-Builts recognized the need for more precise and up-to-date drawings and information for construction and renovation projects. Through job related experience, he discovered a lack of quality and timely information being provided to the organizations which require as-built surveys in order to begin the design phase of upcoming projects. He started an organization called Helihawk Associates, which specialized in the creation of architectural as-built surveying and the production of as-built plans using AutoCAD.

The name Helihawk Associates stemmed from Bob Missroon’s experience as a helicopter maintenance test pilot for the U.S. Army where he completed nearly 2,000 flight hours. His time flying Blackhawk Helicopters (UH-60) was among his most memorable experiences while serving in the military. Over the years customers have asked us why we chose our unique name. The name Helihawk is simply shorthand for Helicopter Blackhawk. Recently our organization has ventured into government contracting and in the process has become a certified Service Disabled Veteran Owned Small Business (SDVOSB).

After officially incorporating the company in 2000 as Helihawk Associates, the name later changed to “Precision Architectural As-Built Services, Inc.” in 2010, in order to have a name that most accurately represents the service we provide. Precision As-Builts still retains the existing customers that have been loyal to our organization since 1999. Since the early days of Helihawk/Precision our organization has completed over 6,000 as-built surveys for architects, retailers, banks, grocery stores, high-rise corporate headquarters, educational facilities, homeowners, etc… Several of Precision’s customers have ordered hundreds of surveys each over the years, as the quality and consistency of the work we provide has always been our highest priority. We hope to have an opportunity to serve you for all of your upcoming as-built surveying needs present and future!


Precision Architectural As-Built Services, Inc. is a CVE verified service-disabled-veteran-owned-smal-business. For architects working on government contracts, Precision helps to achieve their SDVOSB sub-contracting goals. Our team plans to survey a large number of VA hospitals due for renovation and building/equipment upgrades.
