MTI-KCE was contracted to perform all inspection, sampling, and testing to verify that the construction complies with the plans, Prime Agreement special provisions, and specifications.  This included preparation of reports and notifications of non-conforming work/failed tests, records management and record keeping.  

Inspections and compliance reports were performed on materials including soil, concrete, aggregate, structural steel, and asphalt.  Sampling, testing, and special inspections were performed by our staff with relevant certifications and up to date training.  Engineering technicians and special inspectors were available both day and night shifts for concrete placement and asphalt paving to facilitate traffic lane closures.  

Our knowledge and services aided in the successful completion of this project.

Modifications were needed at the existing dams to provide the appropriate facilities and devices for releasing, measuring, monitoring, and regulating the required flows under the new FERC license conditions.

The new FERC license and the associated recommendations by the United States Forest Service (USFS) under Section 4(e) also required significant upgrades to project roads, restoration to several spoil pile sites, addition of new recreation facilities, and measures to improve the visual aspects of the project. In addition to the relicensing improvements, PG&E will construct a new 2.8 MW Britton Powerhouse in conjunction with the proposed instream flow release facility at Pit 3 Dam (pictures show before and after).

MTI-KCE was contracted to perform all necessary tests and inspections required to verify the quality of construction as specified on the Drawings and in the Specification or as otherwise necessary to assure sound and professional workmanship and the integrity of the final product.  This included field and laboratory testing of soil, concrete, and aggregate.  Materials not tested in the field were immediately transported to our full-service laboratory for necessary testing.  Continuous monitoring and special inspection to provide the design-build team information without slowing the work progress was essential. Full-time inspectors were re-located to the remote site to meet the aggressive schedule.  Inspections and compliance reports were performed on materials including soil, concrete, anchors, structural steel, and asphalt.

In addition to testing, observation, and special inspection; our engineering staff worked closely with the design-build team to provide geotechnical consultation and slope monitoring.  Slope stability and inclinometer/extensometer monitoring were important tools for construction within the steep canyon setting of the Pit River.  A slope stability analysis was necessary for the crane pad adjacent to the Pit 3 Dam.  In addition, slope inclinometers and extensometers were installed and monitored by our engineering staff during the cut slope excavation and rock bolt installation.  

Our knowledge and services aided in the successful completion of the improvements for this project.
