A “No-Surprises” Approach

DSI excels in providing innovative and dependable preconstruction information and solutions. Our preconstruction team boasts exceptional expertise and extensive experience in conceptual budgeting, scope development/management, design assistance, and estimating.

Through the integration of advanced technology and superior customer service, our approach aims to deliver customers a comprehensive and cost-sensitive estimate. We understand the significance of collaborative work with the construction team, emphasizing the value of comprehending and developing a complete scope that aligns with our clients’ needs. Our commitment and focus are geared towards covering every aspect to ensure there are “no surprises.”


DSI’s core estimating services team, located at our corporate office in Austin, brings together decades of collective experience in mechanical piping, HVAC ductwork, plumbing, and process systems. The team, which includes master plumbers and certified plumbing designers, possesses significant field expertise. Additionally, each branch office contributes to the overall preconstruction and estimating capabilities of the entire team.

Utilizing digital estimating software, we conduct quantity surveys for piping, plumbing, and ductwork systems, tailoring the software to accommodate the diverse range of our estimates. Our system incorporates features that allow us to dissect and analyze various components of an estimate by system and area. This capability enables us to perform value analyses by comparing budgets and estimates from similar projects, considering alternate materials and methods. Every system undergoes evaluation for critical pathways, cost, and schedule considerations.
