Below are the previous updates for the Station E substation project.

Phase 1B construction status: 8/8/18

Construction has been underway for just over 100 days, mainly focused on excavation and removal of waste materials. Project excavation is nearly 90% complete and progressing well.  Contaminated/non-suitable material removed from the site to date is approximately 15,000 cubic yards and broken down by class below:

Material Type

Cubic Yards

Number of Truckloads

Class I

12,227

696

Class II

1,919

147

Backfill and additional materials using haul route

With the excavation nearing completion, we'll begin importing 45,000 cubic yards from Bell Marine, using internal roads we connected between the two locations. After the Bell Marine material is exhausted, we'll import from another local source less than 2 miles away. The import from the second source is anticipated to begin at the end of August and continue for approximately 18 working days.

We anticipate utilizing approximately 20 trucks per day, making 10 trips each for this final soil import. We have estimated an additional 60,000 cubic yards of soil is needed to bring this phase of the project to grade.  These trucks will utilize the designated haul route as planned. 


Phase 1B construction status: 7/16/18

The project excavation is over 40% complete and progressing well. Approximately 11,300 cubic yards of contaminated material has been removed from the site to date, broken down by class below:

The project excavation will continue as planned with stockpiling, testing and segregating materials for removal or reuse at the site. Materials suitable for reuse are being placed back and re-compacted to meet the geotechnical requirements of the site. So far we've reused 57,995 cubic yards.


 Phase 1B construction status: 6/21/18

Site excavations and operations continue daily as planned. Contaminated material removal from the site to date is approximately 460 truckloads.

Site haul off has not occurred since 6/11/18, as the contractor is currently focusing on reuse of stockpiled soils that have been screened, tested and cleared for reuse at the site. These stockpiled materials are being placed back and re-compacted to meet the geotechnical requirements of the site.

Additional haul off will begin again as reuse is placed and further excavations occur.


Phase 1B construction status: 5/31/18

Site excavations and operations, including the off-haul of materials, continue daily as planned. Materials on the site continue to be screened, cleared of debris, categorized and tested for potential reuse. To date we have removed 500 tons of material from the site in 190 truckloads, operating about 20 trucks daily in the removal process.


Phase 1B construction status: 5/16/18

Shoring installation has progressed well and should complete by this Friday, ahead of the schedule. Site excavations and operations, including off-haul of materials, continue daily as planned. We are currently operating about 20 trucks daily. 

The contractor will suspend operations for the Memorial Day holiday starting early afternoon on Friday, May 25 and plan to resume work on Wednesday, May 30.


Phase 1B construction status: 5/7/18

SMUD crews are working with our construction contractor near the existing substation to prepare for the installation of shoring, which is used to support the vertical faces of the excavation areas near the existing infrastructure. Expect moderate vibration from the heavy equipment installing the shoring from 7 AM to 5:30 PM Monday-Friday and possibly Saturdays from 8 AM - 4 PM. Shoring materials start arriving 5/7/18 and continue through the week. The installation is expected to last through the end of May.


Phase 1B construction status: 4/27/18

SMUD’s contractor, Cape Environmental has mobilized to the job site and is preparing to start to construction activities April 30, 2018. Excavation and off-site hauling activities will begin in May and continue through August.  Backfilling and grading with clean soil will begin in May and continue through September. This phase of construction is currently planned to be complete in October.
