L.D. Docsa acted as a General Contractor self-performing 80% of the contract work, in a collaborative design-build approach. My continued use of their construction services post project completion is indicative of my satisfaction with their work and look forward to continuing the relationship throughout the future.

BHSJ JOINT WWTP

LDD has performed multiple projects at the Joint Plant - some with high degrees of complexity requiring extensive coordination. Each project was performed within budget and with minimal interruption in operations. The LDD team employs very competent personnel and has access to multiple resources to complete difficult projects in a professional and timely manner. Any organization would be well served by selecting LDD as their construction professionals. I would highly recommend LDD and look forward to working with the firm in the future.

STANTEC

Your site leads Jason Scott and Nick Peterson did a wonderful job. Jason’s experience with clarifier rehabilitation and equipment replacement was evident, and Nick clearly knows concrete/site work. Their focused approach, effective communication, work ethic, and overall commitment to quality quickly established a high degree of trust in the owner and engineer. We could not be more pleased with the execution on this project. Well done!
