Precise and accurate survey data is vital
to each project’s success. Our experienced survey team has surveyed over 750,000 acres and ensured that each project starts with accurate and detailed topographic
data within the past five years, .
The predesign process is a collaborative planning effort. It involves preparation, coordination, and working in tandem with our clients to identify project goals, technical scope, and cost to meet the client’s vision, project schedule, and budget.
Our team identifies design solutions
through an iterative process.
This method produces a final
design solution that is technically
sound and optimizes all technical
and budget components.
We provide post design services
(bidding and construction) that include: administration, oversight, inspection,
and management in order to safeguard
our client’s implementation after
the design is complete.
