• Our understanding of the underlying engineering results in effective and efficient construction.
  • Our construction professionals are used to working on challenging and highly constrained projects.
  • We specialize in retrofits, improvements to existing features, major repairs, and challenging restoration projects.


The ultimate purpose of engineering is to build stuff.  So it’s no surprise that, after many years of engineering streams and stormwater infrastructure, we brought together a talented team of construction professionals to build and repair what we design.  By applying core principles of engineering practice and ethics to building, we approach construction in a unique way that ensures the highest level of value to our client.  Our sole focus on streams, stormwater, and drainage; and the diverse skillset of our staff combine to establish us as the go-to firm for reliable and cost effective stream and stormwater repairs and construction.

The roots of our construction practice started by being repairing existing facilities and organically evolved to a sole-source prime contractor, often in a design/build role.  The evolution resulted in gaining a reputation as a firm that can get things done efficiently in highly constrained and challenging situations.  This translates well being a DBE/WBE subcontractor, as prime contractors know we are responsive and have the capabilities to play a key role on larger projects.

As existing infrastructure specialists, our niche is in retrofits, improvements to existing features, major repairs, and challenging stream restoration projects.  New practices, including Low Impact Development (LID), Environmental Site Design (ESD), and natural channel restoration techniques are our speciality.  Our firsthand knowledge or the engineering behind every design ensures a high quality construction product.
