Gir-Mac Construction, LLC is owned by Adam Girgen and Ed McNamara.  Both Adam and Ed are Hastings residents and are experienced in many aspects of construction.  Gir-Mac Construction was started in 2002 with the mission of providing high-quality construction services throughout the Twin Cities area at affordable prices, while offering above-average customer service and results.  The work done by the Gir-Mac Construction Team is truly a Reflection of Perfection.  Adam and Ed are known to be hard-working, reliable, and extremely knowledgable in their field.  They approach each job with enthusiasm and compassion to ensure 100% Customer Satisfaction.




Adam’s experience started with a St. Paul Union Electrical Shop.  There he estimated many large residential and commercial projects.  Projects ranged in size from $500 – $1.5 Million.  Adam orchestrated manpower for multiple jobs, conducted meetings with owners, architects, engineers, and purchased materials needed for each job.  After several years with this company, Adam was approached by a General Contractor to be hired on as an estimator / project manager.  In his new role he worked for a company that specialized in a wide variety of home improvement projects ranging from full additions, interior remodel work to large scale association projects.  While there Adam also worked closely with property management companies on a variety of projects from annual maintenance contracts to window, siding, and deck replacement.  The combination of Adam’s previous work history, knowledge in estimating, project management experience, coordination skills, strong work ethic, and his desire to offer the highest quality construction possible lead to the partnership with Ed McNamara and the beginning of Gir-Mac Construction.



Ed’s experience started as a Union Carpenter, Journeyman framing commercial and residential projects throughout the Twin Cities area.  There he gained a wide range of experience from concrete to framing to trim work.  Ed then moved on to work for a large custom homebuilder for 13 years where he worked on a variety of projects from framing whole homes and townhomes to building decks.  Ed was then promoted to the Head of the Service Department where he personally took care of all homeowner issues.  It was in this role that Ed impressed with his superior customer service skills and timely issue management procedures.  Near the end of his time at that company Ed moved on to become a Job Supervisor where he managed residential construction projects consisting of 100+ unit housing developments from the ground up.  Ed had learned a great deal from his variety of previous roles and set out to start a local construction company, Gir-Mac Construction, that would become known for its knowledgeable and honest staff, superior work product and high-quality projects.
