Each of our principals has extensive expertise in and is responsible for a specific area—plumbing, piping, sheet metal or operations. This specialization, coupled with a strong labor pool, assures our clients a job well done, on budget and on schedule.

Scott Krum, Principal/President
Scott’s ability to facilitate collaboration among three union trades, owners, architects and engineers is key to Legacy’s rapid growth. A mechanical engineer, he contributes expertise gained from a diverse field of projects ranging in value, schedule and specialty. He has managed labor and budgets on contracts in excess of $12 million, including the ACE-award winning Flatirons shopping complex. Scott’s system-design expertise is evidenced in Legacy’s training, scheduling, project control and expense-tracking processes—all of which directly benefit our clients’ budgets and timelines.

Donald Alstrup, Principal/Vice President
Don brings nearly 30 years of commercial and industrial plumbing and piping experience to Legacy engagements. He has successfully managed projects exceeding $10 million and requiring 75-plus tradesmen. Among Don’s career highlights are his involvement as a general foreman for the construction of Coors Field and Invesco Field in Denver, the Budweiser brewery near Fort Collins and Intel headquarters in Colorado Springs. Other plumbing and piping projects of note include two Denver International Airport Concourses and their respective utility tunnels. 

Eric Alstrup, Principal/Vice President
A journeyman plumber with some 30 years of field, labor management and operational experience, Eric’s trademark enthusiasm is a true Legacy asset. He served as a superintendent for Colorado Mills Mall, as general superintendent for Southlands Mall and the Meridian luxury high-rise complex, and as a general foreman for Coors Field, Denver International Airport and Winter Park’s Zephyr Mountain Lodge. As labor director for a large Denver-based industrial mechanical firm, he was responsible for all field labor related areas (plumbing, pipefitting, workers, operations and teamsters) and handled all union labor business.
