Pipe Support Replacement Project
Pipe Support Replacement Project
Chevron Refinery
Project Background
Civil construction to widen and increase the mass of 57 existing concrete foundations and upgrade the baseplates and structural steel on 40 bents.
Scope
- Project Specialties
- Excavation
- Underground
- Masonry
- Structural Steel
Challenges
Completing seismic repairs and upgrades to the existing Standard Road Pipe Rack that was built in the early 1970s and experienced severe damage due to corrosion at multiple beams, columns, vertical bracing and anchor bolts – all in accordance with the 2013 California Accidental Release Prevention Program Seismic Assessments and the 2016 California Building Code. We also performed voluntary modifications to the lateral-force resisting system.
Solutions
Faced with difficult excavations that required abnormal shoring installation and complex layout, we noticed an unexpected large boulder that presented a hazard to performing the necessary excavation. We helped redesign the structural upgrades and eliminate the hazard of the boulder, keeping the field crews safe during the seismic retrofit.
Project Success
Provided constructibility and value engineering for the retrofits and to the soils engineer.

Firewater Line Replacement
Firewater Line Replacement
CHEVRON REFINERY
Project Value: $1.2 Million
Background
The Firewater Line replacement program was a complex project involving civil and mechanical scopes. The project included the replacement of the existing line, which required extensive excavation, sand backfill, and paving.
Scope
- Project management: set-up, and mobilization.
- Material procurement as shown in specifications and contractor workbook
- Fire-watches
- Traffic control
- Excavation, sand backfill, and paving
- Trench plates
- Layout and weld-bay piping prefabrication
- Field piping fabrication, hydro-testing, installation, and tie-ins
- Coat and wrap underground CS piping and flanges
- Guard post installation
- QAQC and document submittals
- Clean-up and demobilization
Project Highlights
- Completed 150 carbon steel welds
- Completed 76 HDPE fusion welds
- Installed 475LF of HDPE pipe
- Excavated 270 cu yd of material
- Imported 250 tons of clean rock fill, 110 tons of sand fill and 150 tons of aggregate base rock
- Import level and compact 60 tons of asphaltic concrete paving
- Coordinated excavation and mechanical scope to limit the risk of open dig sites
Challenges & Solutions
The firewater line project required being set underneath an operational street. Due to the activity of the street, it needed to be open for traffic during non-construction hours.
During the project, we encountered multiple subsurface obstructions. There was also a high-water table that could affect the excavation and installation of the new line.
With great coordination between the team, we were able to restore the roadway daily with trench plates and shoring to keep the road operational after hours.
With multiple obstructions found, we recommended and installed various piping modifications to the firewater line. Due to the high-water table, we ran pumps to pull out excess water to be able to continue work.
Project Success
Successfully completed the project with a recorded 13,500 safe man-hours worked.

Substation Infrastructure
Substation Infrastructure
CHEVRON REFINERY
Project Value: $3 Million
Scope
Site work and foundations for new substation and electrical distribution infrastructure. Included Installation of power poles and conduit to support construction of new substation.
- Earth Moving
- Grading
- Paving
- Underground
- Masonry
- Mechanical Piping
Challenge
Substation site was in an inaccessible hillside behind a main active refinery pipeway.
Solution
We constructed temporary access over the pipeway for mass excavation and construction of a 35-foot tie-back wall and secondary wall. Because of the topography and site access, we excavated and sloped the entire slope, constructed the wall to full height, drilled tiebacks then installed and tensioned through the new wall in concert with the wall backfill. We removed the old pipeway for access and constructed a new pipeway above and around the substation — completing the piping tie-ins without disrupting refinery operations.
Multiple power pole foundations of differing designs for the main feeder were constructed for the 115Kv feeder lines into the substation, some up to 10 feet in diameter and more than 40 feet deep and others being large pile-supported concrete foundations with 15 to 20 piles each. We constructed all underground duct banks as well as the elevated substation foundation and associated structural steel. New distribution pole foundations were constructed, again with some being large deep drilled piers and other being pile-supported hollow concrete poles.
Project Success
Provided constructibility for routing of new pipeway, allowing us to successfully transition into construction of the actual substation.
Quarry Firewater
Quarry Firewater
CHEVRON REFINERY
Project Value: $5 Million
Scope
Tank Site Work which included removal of 300,000 cubic yards of hillside, processing of removed material and re-installation of processed material to facilitate new quarry firewater tank.
- Earth Moving
- Grading
- Paving
- Underground
- Masonry
- Mechanical Piping
Challenge
The client had selected a location for the new firewater tank to maintain proper pressures to the refinery firewater system without the addition of pumps. Engineering asked us for constructibility of new foundation and execution.
Solution
While the original design showed removing hillside and importing new structural fill material from local quarries for the foundation, we processed the existing removed material for uses as the structural fill.
Project Success
Our innovative approach resulted in a client cost savings of $2 million.
