A successful project begins with listening to the client to determine precisely what they want to accomplish. From there, we organize a scope of work that matches your objectives to all regulatory codes, ordinances, and professional standards.
We customize a scope of work to fit both your budget and the regulatory requirements that will be encountered. Our land surveyors routinely capture and compile topographic and boundary data incorporated into engineering design, boundary identification, legal descriptions, elevation certification, construction layout, and as-built records.
From 15 miles of Mississippi River levee to a $750 million plant expansion — a selection of projects that demonstrate the depth of our practice.
A 380,000 sq-ft addition with extensive site improvements: new truck access roadway, loading docks, employee entrance and parking, storm water detention facilities and pump station. Detention basin and outfall design adjacent to a regulated wetland, with permits acquired through USACOE. PCC access roadway design included fly-ash modification of unstable, high-moisture sub-grade soils.
Comprehensive stormwater management plan for a $750 million plant expansion — multiple storm sewer systems, pump stations, force mains, detention basins, outfall structures, and secondary containment. Designed to meet suspended-solids removal targets and USEPA Stormwater NPDES / Clean Water Act Phase II requirements, with additional surveying and construction layout.

Boundary, topographical, as-built and construction layout surveys plus full site development plans for a 185,000 sq-ft downtown recreation facility — including streetscaping for pedestrian accessibility, landscape enrichment, utility relocation, and pavement restoration on surrounding streets.
Topographic survey, site and infrastructure design, specifications, cost estimating, and bid document preparation for a 245,000 sq-ft building addition with underground parking — including privatizing Cambridge Street as the main entrance, with street improvements and utility coordination.
Topographic and boundary surveys, plat of dedication, site improvement plans and construction layout for a new 47,000 sq-ft school with track & field facility, football field, soccer fields, playground, two parking facilities, underground utilities, and storm water detention ponds.
Survey, design, construction observation and staking.
Topographic survey and site development plans: grading, coordinate geometry, parking lot design, utility design, soil erosion and sediment control, and full baseball field design, layout, details and specifications.
A 65-lot subdivision on 40 acres containing 10.5 acres of wetlands. Storm water collection designed to LEED standards using bioswales, wetland plantings, rain gardens, and sediment traps to meet the Clean Water Act — plus annexation, platting, wetland mitigation planning, SWPPP, utility design, and a full design report covering density, zoning, economics, utilities, and traffic.
Complete land surveying for every type of project, from inception through completion — the highest quality of workmanship while keeping your project under budget and on schedule.
Construction layout for new stores — staking for building grid lines, parking lot pavement, light poles, traffic signals, storm & sanitary sewer, and water mains.
