Why Choose Us
Veteran Owned Small Business
VOSB founded by former U.S. Army non-commissioned officer and combat veterans that believe in “a commitment to building excellence by inspiring intelligent and tenacious teamwork” throughout every project.
We provide an intelligent and innovative hands-on approach to the entire process of building and our customers reap the rewards of our management team's proven experience.
Mammoth Gold Standard
Our exclusive Mammoth Gold Standard ensures that owners and municipalities receive a warranty by which all other construction warranties are judged; delivered upon the completion of each project.
Mammoth’s approach to pre-construction is to develop an integrated partnership with each client. We embrace the task of assembling a team to construct your project’s design under various conditions while maintaining the budget, schedule, quality, and safety goals.
A Core Team of Subcontractors
Many contractors base their bids without vetting their subcontractors competency first. We work tirelessly to prequalify new subcontractors to work symbiotically with our already prequalified and consistent core of subcontractors.
Safety First Culture
We are proud of the safety training and site-specific safety planning we provide and promote at Mammoth which has helped us achieve a current EMR of .74 and zero job safety complaints.
