Design Surveys

Before a project can be designed, the engineer needs to know everything that could affect a potential design including existing design features and ownership. EEC has provided design surveys for our own engineering department as well as for various other engineering firms.

Service Areas Include:

  • Topographic Surveys
  • Easements
  • Boundaries
  • Contours
  • Utilities

Project Experience:

Pontatoc Road, Tucson, Arizona

EEC provided a design survey of four separate areas for safety improvements. The existing right of way was located to ensure improvements did not encroach onto private property.

Los Reales Landfill, Arizona

EEC provided a design survey to Pima County Solid Waste at the entrance to Los Reales Landfill for the addition of a scale. EEC also provided this survey to our in-house hydrology department for retention/detention and design of drainage infrastructure to resolve surface drainage problems at the site.

On-Call Flood Control Engineering for Pima County Flood Control District, Tucson, Arizona

EEC provided design surveys for several drainageways in Pima County, Arizona, including Drainageway No. 13 in Green Valley.

Pima County Wastewater Management Relief Sewer, Tucson, Arizona

EEC was contracted by another design firm to conduct a field survey of existing sewer lines near St. Mary's Road and Granada Street. This horizontal and vertical data was used to design a new overflow sewer connecting two major interceptor sewers. Data had to be extremely accurate and detailed to ensure the new design would be functional.

Interstate 10, Marana to Cortaro, Tucson, Arizona

EEC was awarded a contract for the widening of 10 miles of I-10 north of Tucson. Accurate existing-conditions information was required to ensure new designs would match the existing pavement horizontally and vertically. Conventional survey techniques were not efficient or safe due to high traffic volume and speeds. EEC's innovative surveyors mounted their GPS system on the fender of a truck, set the unit to "continuous data collection" and, under the supervision of the Arizona Department of Public Safety, collected 40,000 horizontal and vertical data points in three nights of work. The data was checked for accuracy and was used in the final design.

Rancho del Lago Subdivision, Sahuarita, Arizona

EEC performed a design survey of Old Vail Road to allow designers to prepare plans for both onsite and offsite improvements.
