Poor and expansive soils were a major concern at this location. LEI Engineering and Surveying of Oregon’s Engineering Geologist, Stephen Palmer performed geologic investigation to classify soils and determine prescriptive measures for design and construction. This also included performing soil infiltration testing using a cased falling head test.
LEI Engineering and Surveying of Oregon developed site design civil engineering plans for road access and site development. Drainage around the green houses was a serious concern due to the expansive soils at the site. Following engineering geologist recommendations, LEI Engineering and Surveying of Oregon designed a sub-drain around the buildings to drain water from the foundation soils
Stormwater runoff treatment for this site was addressed with a large wet and vegetated detention pond. LEI Engineering and Surveying of Oregon worked with the project landscape architect to develop a planting plan and design that included an island in the middle of the pond.
LEI Engineering & Surveying of Oregon completed the presale services for 31 units selected for treatment to reduce fire risk and to address pest damage for the USFS in Republic, Washington. These services included unit layout, unit boundary flagging, unit GPS mapping, development of logging systems worksheets with maps, and boundary painting. The timeline of this contract was meant to span two seasons: 2019 and 2020. After work on the contract began, there was a desire by the Forest Service technical staff to complete the contract sooner if possible. To address this desire, LEI Engineering & Surveying of Oregon accelerated the work plan for project work and completed all work in fall of 2019, one complete field season ahead of schedule. This allowed the Forest Service flexibility to potentially put the units out for public auction in spring of 2020.
Through the life of the project, LEI Engineering & Surveying of Oregon worked closely with Republic District staff to ensure that work completed by LEI Engineering & Surveying of Oregon met Forest Service objectives and that any changes needed were quickly addressed. This included the LEI Engineering & Surveying of Oregon project manager meeting with the COR at the District Office, or in the field, 2-3 times per week while field activities were underway. LEI Engineering & Surveying of Oregon also provided the COR with a weekly work deployment schedule showing where LEI Engineering & Surveying of Oregon field personnel would be working and objectives for the week. This gave the COR ample time and flexibility to schedule inspections and to provide input to LEI Engineering & Surveying of Oregon staff as work was being performed.
LEI Engineering & Surveying of Oregon is excited to been a part of this project to improve the health of our national forests and reduce the risk of forest fire.
Softree RoadEng is the Forest Industry standard in road design software. LEI Engineering and Surveying of Oregon has been using this software platform in its practice as professional logging engineers since 1997, completing the design of hundreds of miles of new low volume roads.
Through this extensive use of Softree RoadEng for to complete low volume road design projects, LEI Engineering and Surveying of Oregon has developed an approach to design that works effectively and efficiently for logging road construction. LEI Engineering and Surveying of Oregon has documented this approach in a training manual and accompanying DVD.
This training material has been perfected over the last 10 years and provides excellent prescriptive practices that foresters and logging engineers can quickly learn and deploy to properly address their logging road design needs.
LEI Engineering and Surveying of Oregon was proud to be able to present the most updated version of LEI Oregon’s training material based on Version 8 of Softree RoadEng to The Campbell Group staff.
