Our fleet of equipment and skilled craftsmen allow us to provide turn-key services to our client with lower budgets and tighter time frames.

Equipped with a $1.5M fleet of equipment and over 50 on-site tradesmen, we have the resources and ability to provide demolition services to our clients. Every item performed with our own crew results in savings passed on to our clients. Demolition services involve everything from buildings, concrete tanks and structures to piping systems and equipment. 


With our extensive fleet of equipment which includes mobile cranes, excavators, loaders, dozers, etc., L.D. Docsa is able to self-perform our own earthwork on all projects, giving us an advantage over the competition with a quick start project. We also install the underground utility piping for water, wastewater, chemical feed, air, etc. You name it, we can install it. And as construction nears completion, we also handle our own final grading work.

Concrete Construction

From aeration tank construction to sidewalks, our skilled crew has the knowledge and tools necessary to complete any concrete construction task. We also own several types of concrete forms, allowing us to forge ahead at any moment.
