Services
Roadway Design
Our roadway design services encompass complete street development from conceptual planning to construction documentation. We specialize in creating efficient transportation solutions that meet municipal specifications while addressing drainage and utility requirements. With decades of experience in Northwest Indiana's unique terrain, we deliver designs that balance functionality with cost-effectiveness for both new developments and infrastructure rehabilitation projects.
Boundary Surveys
We conduct precise boundary surveys to establish property lines and resolve land ownership disputes. Our ALTA/NSPS certified surveys meet title insurance requirements while our cadastral surveys document legal land divisions. Utilizing advanced GPS technology and historical records analysis, we provide accurate boundary determinations that protect property investments across Northwest Indiana's evolving landscape.
Storm Water Drainage
Our stormwater management solutions prevent flooding and erosion through comprehensive drainage system design. We analyze watershed characteristics and local regulations to create sustainable systems that handle runoff from roads and developments. Our engineers optimize detention basins and culvert placements to ensure long-term performance while maintaining compliance with environmental protection standards.
Construction Layout
We provide accurate construction staking services to guide infrastructure development. Our surveyors establish precise reference points for roads, utilities, and buildings using modern equipment and 3D modeling. This ensures proper alignment and grading during construction phases, minimizing costly field adjustments while maintaining adherence to approved engineering plans and municipal requirements.
Subdivision Development
We offer end-to-end subdivision design services from initial concept to final plat approval. Our team coordinates utility infrastructure, roadways, and lot configurations while navigating municipal zoning regulations. With extensive experience in both residential and commercial developments, we streamline the approval process through accurate engineering analysis and comprehensive documentation that satisfies all regulatory requirements.
