Value Engineering & Constructability

Bridging the gap between design consultants and site contractors. Reviewing plans during approvals to cut millions of dollars in unnecessary cut/fill export, retain walls, and redesign delays.

  • Residential interim grading designs balancing lot basements on-lot
  • 3D concept grading and utility balancing before final engineering
  • Over 1,000 land development plans reviewed for constructability QC

BIM Modeling & Utility Coordination

Specialized 3D BIM coordination focused exclusively on underground wet and dry civil site utilities. Eliminating subsurface spatial clashes before pipes arrive on site.

  • Dry utility models: electric, telecom, gas, and conduit banks
  • Wet utility models: sanitary, water mains, storm basins, and detention
  • Navisworks NWC/NWD deliverables and active weekly team coordination

Philadelphia International Airport: Runway 17-35 & Employee Parking Expansion

"After meeting with MESH and reviewing the progress on our models for the extension of Runway 17-35 and the Employee Parking Lot Expansion at the Philadelphia International Airport, I was thoroughly impressed with the level of detail. We have had great success on the parking lot and have complete confidence we will have the same results with the Runway extension. It was well worth the investment."

Technical Rigor

The Survey-Quality Engineering Advantage

Why civil contractors rely on MESH's engineer-reviewed models: the mathematical logic chain that reduces survey layout expenses and prevents costly field busts.

01 →

Built from True Geometry

Raw CAD contours drawn by designers lack fine grading details for basins, curbs, and swales. MESH builds TIN models from true horizontal alignments and vertical profiles.

02 →

Single Unified Data Pipeline

Data is engineered once and shared simultaneously between GPS machine control dozers/graders and field rover stakeout, eliminating duplicate calculations.

03 →

Pre-Mobilization Conflict Resolution

Inconsistencies and geometric plan bugs are caught in our office with the civil design engineer before operators and heavy iron mobilize to the job site.

04 ✓

Accurate Quantities & Payment

Accurate control plus check shots delivers exact existing vs. proposed ground surfaces, ensuring contractors get paid for every cubic yard of dirt moved.

Direct Engineering Answers

Frequently Asked Technical Questions

Direct, factual answers regarding file delivery, hardware compatibility, tolerances, and engineer onboarding.

What makes MESH machine control models survey-quality compared to standard data prep shops?
Unlike commodity data prep shops that simply trace contour lines, MESH builds 3D models from true horizontal and vertical geometry. Every surface is authored and reviewed by licensed Professional Engineers, resolving plan discrepancies before machines mobilize to prevent field rework and restaking expenses.
Which GPS machine control equipment and file formats does MESH support?
MESH provides complete cross-platform compatibility for all major machine control ecosystems including Trimble (Earthworks, GCS900, SCS900, .cal, .ttm, .dxf), Topcon (3D-MC, Pocket-3D, .gc3, .tn3, .ln3), Leica (iCON, .geo, .trf), as well as standard LandXML, AutoCAD DWG, and MicroStation DGN files.
What is the typical turnaround time for a 3D site model?
Standard commercial and subdivision 3D machine control models are typically delivered within 5 to 7 business days following plan and CAD delivery. For high-priority mobilizations, emergency stakeout, or fast-track highway operations, expedited turnaround within 48 to 72 hours is available upon scheduling.
What information does MESH require from the design team to initiate a model?
To produce an engineer-verified model, MESH requests full CAD drawing files (AutoCAD .dwg or Civil 3D), approved civil design plan sheets in PDF (grading, drainage, utility, and geometry plans), and site coordinate control or project datum specifications.
How does MESH resolve underground civil utility clashes before trenching?
MESH builds federated 3D models of wet and dry utilities based on true invert elevations, pipe outer diameters, and trench specifications. Utilizing Autodesk Navisworks clash detection, we identify spatial conflicts against storm basins, foundations, and paving subgrades during weekly coordination meetings.
Where are MESH field survey crews deployed?
MESH deploys 7 dedicated field crews across Pennsylvania, Delaware, New Jersey, Maryland, and Northern Virginia from our offices in Eagleville, PA and Wilmington, DE. Our virtual engineering, 3D GPS modeling, and value engineering divisions support civil projects nationwide.
