Project Value: $500,000
Scope
Fresno P&DC operations and employee lot asphalt replacement included the removal and replacement of 170,000 square feet of existing asphalt concrete.
- Critical scheduling
- Excavation
- Asphalt Paving
- Striping/Pavement Markings
Challenge
Project needed to be performed in an operational facility.
Solution
Management and leadership came up with solution with the postmaster to allow for continuous operation of the postal facility. Coordination included phasing and swing shift work.

Challenge
Maintaining unimpeded access to the current loading rack while completing civil/structural, mechanical and piping installation for the replacement sulfur truck loading rack to increase the truck loading capacity and improve safety.
Solution
By coordinating with operations and traffic plans during the 12+ month project to off-haul sulfur at the existing loading rack, we assisted in constructing the new loading rack without impeding necessary truck traffic.
Project Success
The new rack and its necessary foundations were safely completed.

- Excavation
- Underground
- Masonry
- Structural Steel
Challenge
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.
Solution
Faced with difficult excavations that required abnormal shoring installation and complex layout, we noticed an unexpected large boulder that presented a hazard to perform the necessary excavation began. 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.

Challenge
The underground compressed air line was in a challenging location and a Bay Area Quality Management District Permit and Soil Disposal Profile was not covered in the design drawings.
Solution
We prioritized the project activities and stockpiled the soil for testing to accommodate and achieve the project schedule.
Project Success
We prevented a more than six month delay to the project schedule and new building construction started as planned.
