Throughout our history, ARB has developed a set of skills and expertise across many disciplines. We have a proven ability to complete construction within varied project constraints, be it remote location, limited access, accelerated schedule, or elevated environmental concerns. ARB`s experience, care and diligence, as well as our skilled craft workers and managers, has facilitated many successful projects for our clients throughout the world. This background and experience, enables ARB to continue its goals of growth and continued success in both domestic and international markets.
Construction Equipment
ARB owns, operates, and maintains a fleet of construction and support equipment comprised of over 2000 pieces. We have the equipment and the manpower to adapt to most projects. ARB believes that ownership of the equipment reduces costs and enhances reliability, flexibility, and operational control. In addition, many of our operating divisions use specialized equipment that would otherwise not be available through outside sources, or if available would be prohibitively expensive to rent on an incremental basis. We take great pride in our reputation as having one of the best equipment fleets in the industry.
Our industrial projects include:
- power
- Elk Hills Plant
- Moss Landing Plant
- Kern River Co-gen
- water and wastewater treatment plants
- San Juan Capistrano
- refinery
- Valero Refinery
- oil and gas
- structural steel
- All American Asphalt
- Chevron USA
- Soka University
Elk Hills Power Plant Project Involving Steam Turbine Generator, Step-Up Transformer and Water Disposal Pipeline
The Elk Hills Power Plant contract of over $100,000,000 was a complete turnkey assignment that included the installation of two General Electric 7FA combustion turbines, two IHI heat recovery steam generators, a single General Electric D-11 steam turbine generator, step-up transformer, electrical building and common services building. Bringing Elk Hills on line added 500MW of capacity to California`s critical energy needs. ARB`s scope of work involved all of the mechanical piping, civil work, balance of plant piping, electrical, and instrumentation. All concrete work was self-performed by ARB personnel and also installed were over 11 miles of 16 inch water supply pipeline, 5 miles of 8 inch water disposal pipeline, a 3750 GPM pump station and miscellaneous work associated with that system.
Moss Landing Plant Project Involving Heat Recovery Steam Generators (HRSGs)
Duke Energy turned to ARB for its power plant expertise in building this combined cycle plant at Moss Landing, near Castroville, California. This project involved the installation of four heat recovery steam generators (HRSGs) that included three steam drums on each. ARB also installed all Selective Catalytic (SCR) equipment, the ammonia injection system, stack silencer, and all structural and miscellaneous steel components around the equipment. Project equipment erection included the four Alstrom supplied triple pressure HRSGs, with Peerless SCR systems, on the 1060 MW plant expansion. ARB also self performed all small bore and large bore piping. During the complex construction schedule, ARB used a number of direct-hired crafts, including boilermakers, ironworkers, operating engineers, pipefitters, and laborers. In spite of the challenging schedule, ARB completed the project one month ahead of schedule.
Kern River Co-Gen
ARB carefully planned and orchestrated the work necessary to optimize the placement of the SCR unit at ChevronTexaco`s Kern River Co-gen Facility. The project involved creating space between Economizer ll and l by moving the stack, modification of the duct section, connection of the economizer tubes and setting the new SCR module. After 61 days of pre-shutdown site work, the actual movement and installation was accomplished with only five days of down time. Upon completion, the installation ensured that the catalyst operates within the ideal temperature range, and the new economizer helped to improve steam generation.
