Engineering Design Surveys for Civil and Infrastructure Projects

What an Engineering Design Survey Covers

Engineering design survey is the survey work that supports civil engineering design, collecting the existing conditions, control, and mapping that engineers use to design streets, utilities, grading, drainage, buildings, and other improvements. Design surveys are typically more detailed than standard topographic surveys, often include utility location with potholing or SUE coordination, require precise control networks, and produce CAD deliverables formatted to the engineer's standards. We provide engineering design surveys for civil engineering firms, architects, public agencies, and design-build contractors working on residential, commercial, and public works projects across LA and Ventura County.

Common Reasons Clients Request an Engineering Design Survey

• Public  works design: streets, utilities, grading, drainage, traffic signals

• Site civil design for commercial development

• Multi-family residential site design

• Corridor mapping for street, transit, or utility projects

• PS&E (Plans, Specifications, and Estimates) preparation  for agency bidding

• Caltrans or local agency design submittals requiring  specific control and mapping standards

• Design-build projects requiring survey support throughout  design and construction

• Bridge, retaining wall, or structural design requiring  detailed existing conditions

What’s  Included in an Engineering Design Survey

• Survey  control network establishment (horizontal and vertical)

• Detailed topographic mapping at the engineering scale and  contour interval required

• Visible utility location (water, sewer, storm drain,  electrical, communications, gas)

• Coordination with subsurface utility engineering (SUE) when  underground locations are required

• Right-of-way and boundary information when adjacent to the  project

• Sign, striping, traffic control, and street feature mapping

• CAD deliverables formatted to engineer or agency standards  (Civil 3D, AutoCAD)

• Design coordination during the design phase as needed

Common  Engineering Design Survey Add-Ons

• Subsurface  utility engineering (SUE) Level B or A through partner firms

• Boundary survey for project right-of-way

• Encroachment / easement mapping for properties adjacent to  the project

• ALTA survey when acquisition is part of the project

• 3D laser scanning for bridges, walls, or complex structures

• Construction staking after design is complete

• As-built survey at project completion

What We  Need to Start Your Engineering Design Survey

• Project  location, address, or corridor description

• Design scope and disciplines (civil, structural, traffic,  drainage, etc.)

• Required control and mapping standards (agency-specific)

• Required deliverable format and CAD standards

• Engineer's contact and design team coordination protocol

• Existing surveys or as-built information for the project  area

• Schedule for design milestones

• Permit or agency coordination requirements

Our  Engineering Design Survey Process

1. Scoping.  We confirm project scope, deliverables, control standards, and coordination  protocol with the engineer.

2. Control network. We establish horizontal and vertical  control across the project area.

3. Field work. Our crew collects topographic, utility, and  feature data per the engineering requirements.

4. Data processing. We process field data into the agreed  deliverable format (Civil 3D surface, point database, CAD).

5. Design phase support. We respond to design questions,  perform additional field work as needed, and coordinate throughout design.

6. Final delivery. We deliver the final design survey package  per the engineer's requirements.

Engineering  Design Survey Deliverables

• CAD design  base map (Civil 3D or AutoCAD per engineer requirements)

• Point database with feature codes and elevations

• Survey control report with monumentation and accuracy  documentation

• Topographic contours and 3D surface

• Utility location map and SUE coordination data when included

• Right-of-way and boundary information as applicable

• Stamped survey map when required for agency submittal
