Therrien Waddell Construction is constantly in need of dependable, qualified subcontractors.

We are looking for subcontractors who approach projects as a member of the "Team." As a TW team member, subcontractors are expected to be willing to put forth the extra effort required to achieve project goals, coordinate their requirements effectively and cooperate with all parties involved in a project. At Therrien Waddell, we believe in taking care of our subcontractors by ensuring that those who perform at the highest level continue to receive the advantage of future work opportunities and receive priority status in our organization. Companies owned by women, minorities, and people with disabilities are encouraged to bid.

Please send all bids or subcontractor qualification forms to our Estimating Department by fax at 240.361.4446 or by email to
