SURVEYING/SUBSURFACE UTILITY ENGINEERING (SUE)
Our survey team can complete horizontal, topographic, cadastral, and vertical control surveys for all your needs. For utility location, S.U.E. offers planners, designers, and contractors the benefits of safety, cost control, and accuracy.
Our surveyors are experienced in completing topographic maps, horizontal surveys, cadastral surveys, boundary retracement, construction surveys, and vertical controls.
From a road improvement project in Mount Rainier National Park in Washington to airport improvements in Jordan, Montana, or deep in the jungles of Costa Rica, RPA's surveying crew is ready and able to supply your surveying needs!
RPA's surveying equipment includes Trimble GPS Systems and Trimble Robotic systems. Our professional surveyors and technicians operating the equipment are trained extensively in its use and attend continuing education classes to try and bring the most efficient and accurate methods to the field.
Subsurface Utility Engineering (SUE) accurately maps underground utilities and structures in the development stage of construction. SUE offers public officials, designers, and contractors the benefits of safety, cost-control, schedules met

LIDAR Control Surveys
Control & GPS Surveys
Client: USDA Forest Service - Flathead National Forest
The Glacier-Jim Boundary Survey project began in the spring of 2012 and consisted of section research, search and tie section controlling corners, control, mark, post and clear National Forest boundaries. Robert Peccia & Associates provided a Certificate of Survey, Certified Corner Records, diagrams and point lists to the National Forest Office. We also performed GPS RTK and submitted GPS data for OPUS Solutions for control. All section corners were searched and found or remonumented. All new lines for National Forest boundaries were controlled with GPS RTK and posted with Forest Service decaled posts and rebar with aluminum caps. RPA's surveyors and technicians cleared all boundaries of brush and small trees and blazed larger trees for visual reference.
The project included; Section Corner Research & Search, Control, Mark, Post & Clear National Forest Boundaries, and GPS RTK surveying.
Rimini Road Waterline and Road Reconstruction Project
Lewis & Clark County, Montana
Client: Federal Highway Administration, Western Federal Lands Highways Division (WFLHD)
County Road 695, also known as Rimini Road, is located in the Helena National Forest connecting Highway 12 and the town of Rimini. The project will upgrade the horizontal and vertical alignments to current federal standards and will pave the 6.26-mile route to improve safety and reduce maintenance.
The City of Helena owns and operates a waterline that conveys water from several sources to the Tenmile Creek Water Treatment Plant. The waterline is located adjacent to and within the roadbed of Rimini Road. Robert Peccia and Associates (RPA) was responsible for locating, exposing, measuring depth of cover, and surveying the location of approximately 2100' of the waterline and its associated manholes in eight critical sections designated by WFLHD. The waterline survey and depth of cover information was provided to WFLHD to allow them to adjust the proposed road alignment and profile to avoid the waterline and minimize impacts to the manholes. RPA's SUE division used a mini excavator and a vacuum excavator to expose the waterline. RPA was successful in locating and exposing the waterline without damage to the historic concrete pipe. This project involved coordination with the City of Helena Public Works Department, Lewis and Clark County Public Works Department, WFLHD and interaction with the public.
Southeast Mid-Region Access
Southeast Alaska LIDAR Quality Control
Client: Federal Highway Administration
This project was located on three separate islands in southeast Alaska. The purpose of this project was to survey over 80 miles of road centerline for LIDAR quality control. RPA also set survey control and aerial photo targets for orthorectified aerial photos. The first site was in the Tongass National Forest on Kupreanof Island where RPA surveyed 32 miles of gravel road. Mitkof Island was the second site where RPA surveyed 10 miles of paved highway. The third site was Prince of Wales Island where RPA surveyed 40 miles of gravel road.
Constant cold and wet weather caused the GPS equipment to quit working which proved to be one of the biggest challenges. RPA was able to reconfigure and trouble shoot the GPS which resulted in efficient and economical completion. Ferry travel and logistics to Alaska and between islands throughout the project also required careful planning and resulted in
