PROJECT EXPERIENCE:
Surveying, Photogrammetry & Subsurface Utility Designation & Location Term Contract, Virginia Department of Transportation
Location: STATEWIDE, VA

Project Background: Rice Associates has completed over 160 project tasks for the Virginia Department of Transportation (VDOT) during the most recent seven year period.

This current on-call contract covers a three-year term and involves a base year and two one-year option periods. This is the first time VDOT has ever awarded a statewide contract that combines surveying and photogrammetry with subsurface utilities designation and location.

Work Performed: Rice Associates is providing services including control surveys, aerial mapping, photogrammetry, utility designation and location, hydrographic studies, location surveys, and global positioning.

Representative projects include:

• Route 6 Rivanna and Hardware River Bridges, Fluvanna County, VA: The Rice Associates Team was enlisted by VDOT to provide complete location surveys as well as bridge situation plans for the planned relocation of these two bridges. Rice Associates utilized GPS and conventional surveys to provide ground control for photogrammetric mapping. Utility designation and location is a critical element. A ground supplemented photogrammetric survey is being performed in advance of the routing selection. Once the routing selection has been made, complete bridge situations including flood plain cross sections and hydraulic cross sections will be performed in accordance with the VDOT Survey Manual 2009.

• I-66, Fairfax County, VA: The Rice Associates Team performed a combination of airborne LIDAR, terrestrial scanning and conventional survey for 7.2 miles of pavement rehabilitation in the I-66 corridor from the I-66 / Route 50 crossing to the I-495 / I-66 Interchange. Rice Associates' approach included ground supplemented LIDAR in the open areas, ground drainage supplement, and terrestrial scanning to determine clearances at 15 bridge crossings. This approach saved time and cost and protected both field parties and the motoring public while obtaining the limited details required.
• Route 37 Bypass, Frederick County, VA: The Rice Associates Team provided preliminary survey data for route determination for a badly needed fifteen mile bypass around Winchester. Rice Associates chose to use a diverse combination of survey methods which included airborne LIDAR to gather high level study grade scans of the rolling fields and open areas. This was supported by conventional fixed wing photogrammetry to provide both plan details and breakline data for the LIDAR features as well as to enhance natural feature contour data and plan details at proposed interchanges and intersections. The final product will be used both for route selection as well as preliminary design.
