Selected Experience In Survey Projects



The Dyer Partnership offers the full spectrum of land, mapping, precision control, topographic, utility corridor and site specific surveying services - both independently and as part of a multi-disciplinary team. Our experienced professional surveyors and field support personnel excel in their fields and methods of surveying technology including robotic total stations, GPS and digital levels. By using state of the art equipment, this reduces crew size requirements while increasing productivity and vastly broadens our firm's capabilities.



Pacific Connector Gas Pipeline Project
Southwestern Oregon

This large pipeline project involves routing a proposed 42-inch gas pipeline project from the LNG facility on the North Spit of Coos Bay over to Klamath Falls near the California border. Field surveys were conducted throughout Southwestern Oregon and included use of robotic total stations in the more forested areas and GPS real-time kinetic surveys in the more open areas.

Dyer provided fully equipped survey crews that worked six 12-hour days to meet the scheduling requirements. Field work on the preliminary routing was performed during the summer / fall of 2006 and 2007. Special emphasis was placed on field procedures and notes in order to meet the data collection specifications outlined by the client.




Despite rugged topography and limited access, our firm was able to complete the field work and maintain the delivery schedule that was outlined by the pipeline company.




Design Surveys for Water and Wastewater Treatment Plant Improvement Projects
Various Locations

Our firm specializes in site surveys related to water and wastewater improvement projects. Being a recognized leader in Southwestern Oregon in state-of-the-art improvement projects from membrane wastewater treatment plants to pump stations, site surveys providing accurate and detailed information are required to assure that these projects are successfully designed and constructed.

Field surveys entail locating existing utilities and structures as well as providing survey data for developing digital terrain models (DTM's) for use in site grading and earthwork calculations.





Aerial Mapping Survey
Myrtle Point, Oregon

Highly visible targets were carefully placed throughout the city limits of Myrtle Point for aerial photography. The locations and elevations of the targets were recorded as points of reference to allow the photograph to be converted to a useable map of the area. Mapping requirements were carefully coordinated between the City staff and the photogrammetrist. Survey costs were $7,500, mapping and aerial photograph costs were $17,350.
