Construction Equipment
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.

Wastewater Treatment & Refinery Plant Projects
The San Juan Capistrano project was constructed by ARB to provide the City of San Juan Capistrano, California with a reliable source of good, safe drinking water by recovering and treating previously unusable brackish groundwater. Water and Wastewater Treatment Plant Project The project will allow the City to reduce its dependence on imported sources such as the Colorado River and Northern California currently supplied by the Metropolitan Water District, and is one of the first public-private partnerships under the MWD`s Groundwater Replenishment program. MWD approved the project in December of 2002. ARB provided full-service construction services in partnership with Boyle Engineering and Southwest Water Company. San Juan Capistrano Treatment Plant Utilizing Reverse Osmosis The process utilizes reverse osmosis, or RO, which is used by many bottled water companies and home water purifiers. Incoming well water is passed through semi-permeable membrane elements under high pressure, removing unwanted mineral particles, some as small as individual molecules, after having first been passed through a series of filters. Capacity: 5.14 MGD or 4800 acre-feet of water per year. One acre foot of water is about 326,000 gallons, the amount of water it takes to cover an acre to a depth of one foot, or the amount two families of four would use in a year. Upon completion, this ARB constructed facility will supply virtually all the City`s water needs during the winter months, and about half the water it needs during the summer months. ARB installed over five miles of pipeline as part of this project in order to bring the water from the wells to the plant to be processed. Valero Refinery Project Valero had experienced flame instability and impingement on radiant shock tubes in one of their crude heaters. The deficiency was due to a high-pressure drop in the transition ducting from the convection section to the stack, in addition to air leaks through the doors and joints. The leaks allowed cold ambient air to enter the furnace and increase flue gas, which decreased burner draft. This turnkey assignment was a complete design-build project. ARB`s scope of work included enlarging the size of the three ducts, which necessitated the removal of the stack. Enlarging the ducts reduced the pressure drop and increased draft at the burners, and also provided more uniform flow in the convection section, increasing heater efficiency. Leak points at the doors, flanges and joints were also repaired to eliminate cold ambient air entry into the furnace. All American Asphalt Structural Steel Project Corona, California ARB installed (6) 1000 ton aggragate silos with support structure, truck scales and associated conveying system. Chevron USA Structural Steel Project El Segundo, California installation of over 2,000 tons of structural steel, 26,000 square feet of grating and well in excess of 1 mile of handrail, ladders and stairs. Over 2,000,000 man hours were expended on this project with no lost time injuries.

Pipeline, Cable and Conduit Projects
Our underground projects include: pipeline - Concord - Sacramento - Kern River Pipeline - Pastoria Pipeline Cable and Conduit- Pacific Gas & Electric Gas Distribution- San Francisco - PG&E - Long Beach Water and Sewer- Warner Avenue Relief Sewer - Irvine Regional Park Sewer Conversion Horizontal Directional Drilling Concord - Sacramento Pipeline Project Completed for Kinder Morgan, ARB`s Concord to Sacramento project was an exciting and challenging project for our horizontal directional drilling group. Not only did our crews layout and install 70 miles of 20-inch pipeline, but this project also called for completing 14 drill crossings totaling 19,800 feet through numerous sensitive environmental areas for refined petroleum product. The project included cross-country pipeline methods and much of the work involved construction in congested urban situations. Kern River Pipeline The Kern River Gas Transmission decided to expand the existing Kern River gas pipeline by 700 miles. ARB, Inc. successfully bid on Spread 10 of the Kern River gas pipeline. Spread 10 consisted of 82 miles of 42-inch pipe, while all other spreads required 36-inch pipe, The larger diameter pipe gave ARB, Inc. the greatest challenge of the expansion. ARB met the challenge and completed the project in only four months. The Kern River gas pipeline begins in Wyoming and ends in California, and will provide 900 million cubic feet per day of natural gas. The new pipeline was severely important to provide the increasing need for natural gas. The original pipeline has been running at 100 percent capacity for a few years, and the federal government recognized the importance of the expansion and permitted the project in record time. All the crews and equipment where allowed on the right-of-way only one week prior to the start of the job, because of permitting. ARB had to review every detail of the pipeline and prepare for the worse. The equipment demand for a project of this scope was gigantic, and before the project start-up ARB mobilized 300 pieces of equipment. Three-quarters of the equipment used was owned by ARB. Daggett to Mojave, California- The pipeline went through many environmental and archeological sensitive areas. ARB employees were trained about the sensitivity of the region and the proper procedures incase a situation were to arise. Monitors were placed with every crew along the right-of-way to guarantee a project with minimal disturbance to the area. Over 500 employees worked on the pipeline, including local labor. All employees had to go through safety instruction and drug testing implemented by Williams and additional training required by ARB. Safety is always a priority of ARB. With a pipeline of this size and working to meet a deadline, safety of all employees was a huge concern. The terrain of the project ranged from mountains to river beds. The trench had to be a minimum of 7 feet deep, and the majority was dug using two large trenchers cutting a 60-inch ditch. ARB had 23 directional drills under highways and railroad crossings, all completed with a brand new 60-inch boring machine. Automatic welding systems attached to pipelayers, where used to provide rapid accurate welding along the pipeline. Pastoria Pipeline The Pastoria pipeline called for the installation of 14.05 miles of 20-inch natural gas pipeline. This included fabrication and installation of associated facilities consisting of a meter/regulator station with filter separator, scrubber, storage tank and pig receiver at the Pastoria Energy Facility and a pig launcher and tie-in facilities at the connection point with Mojave Kern River and other related facilities. The project was originally bid for the installation of 12.2 miles of pipeline. Prior to award and due to the presence of Blunt-Nosed Lizard in the area, two re-routes occurred, which added approximately 11,000 feet to the project increasing the total distance to 14.05 miles. Approximately 3 miles of pipe were laid under pavement. This entire section required solid sheet shoring due to extremely sandy soil conditions. Due to permit problems, a section of the project had to be skipped requiring the crew to move to another location which left the highway and continued through a hilly section, most of which is located on the Tejon Ranch (approximately 8 miles). Soil conditions in this area became hard and rocky requiring the use of a ripper. There were many cattle fences on the Tejon property and numerous fence gaps had to be maintained. All vehicles required fire permits and water trucks were used for fire protection. Silt fences were installed for approximately 12,000 feet at various creek crossings. Soil excavated from the creek crossings was set aside and reused in the creek backfill. Culverts were used to divert the water and hay bales were used for filtration. The crews worked with on-site geologists at all creek crossings. Pacific Gas & Electric San Francisco, CA- Cable and Conduit Project ARB completed this project involving an underground conduit system in San Francisco. This Pacific Gas and Electric project involved the installation of utilities underground, allowing the removal of overhead utilities and poles. Our underground construction crews perform what is commonly known as Rule 20 work, converting overhead lines to underground. Rule 20 work includes power, telephone and cable TV. The work most often occurs in older, congested city environments.

Gas Distribution & Water and Sewer Projects
ARB`s underground and industrial operating groups are independent entities yet they work closely together maintaining the corporation`s principles. Our operating groups are made up of an avid workforce who take pride in our work, and are focused on doing the best to ensure quality of work. ARB`s extensive and diverse capabilities allow the corporation to respond to the changing marketplace, addressing traditional client needs, while meeting new challenges, such as accelerated construction of projects or building in sensitive ecosystems. We incorporate the latest technology and have decades of experience in providing the most reliable services. San Francisco Gas Distribution Project In a very congested area of San Francisco, ARB completed a gas distribution project for Pacific Gas and Electric. The work involved, utilizing a mini horizontal directional drilling rig for the installation of 5,000 ft of 2-inch polyethylene natural gas main for main and service replacement work. The directional drilling method allows the work to take place with much less inconvenience to the public by reducing the number of excavations. ARB crews also replaced 210 services to homes and rebuilding all meter sets. PG&E Gas Distribution Project ARB has been working under a system wide contract with PG&E for the installation of guard post protection for natural gas meters. The work typically requires placement of 2-in. and 4-in. steel posts filled with concrete. Several thousand have been completed and our contract calls for 10,000 to be installed over a 3 year period. The projects are small but spread over a large geographic area ranging from Bakersfield, Ca. all the way up to the California/Oregon border. Long Beach Gas Distribution Project ARB was awarded a contract with Long Beach Energy for the replacement of multiple natural gas mains, which varied in diameter from 2-inch polyethylene to 12-inch steel pipe as well as work on 628 services to be replaced throughout the city. Methods of installation included open trench, horizontal directional drilling, cut and bore as well as multiple bridge crossings, which were completed using a barge in the water below. With two crews, the work lasted approximately 7-months. Warner Avenue Relief Sewer Project This construction project stretched from Los Patos and Bolsa Chica to Warner and Springdale in Huntington Beach, California. The project was built entirely within public streets and was composed primarily of three major operations. The first operation was approximately 2,000 LF of 3 reinforced concrete encased 18-inch PVC rapped pipe. The pipe encasement was designed to withstand the load of two lanes of traffic since the actual alignment was not more the three feet from the top of pavement. There were several aspects to the operation that made it unique and difficult to complete. First in order to prevent the pipe from floating in the fresh concrete the encasement had to be poured in three stages. In order to start pouring, a bottom layer of reinforcing steel with vertical bars protruding over the pipe had to be placed first and completed before pipe could be installed and the rest of the reinforcing was placed. The pipe could not be placed in the trench first because there would then be no way to maintain the pipe alignment, this was necessary because the sewer utilized a gravity feed system. The second operation was a 200 LF jack and bore operation that extended underneath the Wintersburg Channel in Huntington Beach. The jacking of the 48-inch steel casing alone was not the difficult aspect of the operation. The ground conditions encountered required continuous dewatering throughout the duration of the process. Three well points were drilled, sump pumps were installed which fed ground water to a desalting tank that then deposited the water into the nearby sewer system. The pumps had to be monitored continuously to ensure that the pumps and the generator powering the pumps were all operating normally. Also, the jacking pit and receiving pits were 30 feet deep in saturated sandy and clay soil with existing utilities running through the area requiring a unique shoring design. The last major operation was construction of 3,500 LF of a 21-inch VCP sewer pipeline, ranging in depth from 5 to 26 feet. Since this area is in close proximity to the Pacific Coast the ground conditions were rather sandy and saturated, which made the trench making portion of this operation very difficult. More than half of the 3,500 LF the trench had to be maintained with solid sheeting; which meant that beams had to be drilled in ahead of the excavating crew and then plates were lowered down between the beams while the trench was being excavated. This was very slow and a dangerous operation taking into account the bad soil conditions, the location of the trench in proximity to live traffic and the overall extreme depths that the sewer needed to meet.

First in order to prevent the pipe from floating in the fresh concrete the encasement had to be poured in three stages. In order to start pouring, a bottom layer of reinforcing steel with vertical bars protruding over the pipe had to be placed first and completed before pipe could be installed and the rest of the reinforcing was placed.
The pipe could not be placed in the trench first because there would then be no way to maintain the pipe alignment, this was necessary because the sewer utilized a gravity feed system. The second operation was a 200 LF jack and bore operation that extended underneath the Wintersburg Channel in Huntington Beach. The jacking of the 48-inch steel casing alone was not the difficult aspect of the operation. The ground conditions encountered required continuous dewatering throughout the duration of the process. Three well points were drilled, sump pumps were installed which fed ground water to a desalting tank that then deposited the water into the nearby sewer system. The pumps had to be monitored continuously to ensure that the pumps and the generator powering the pumps were all operating normally. Also, the jacking pit and receiving pits were 30 feet deep in saturated sandy and clay soil with existing utilities running through the area requiring a unique shoring design.
The last major operation was construction of 3,500 LF of a 21-inch VCP sewer pipeline, ranging in depth from 5 to 26 feet. Since this area is in close proximity to the Pacific Coast the ground conditions were rather sandy and saturated, which made the trench making portion of this operation very difficult. More than half of the 3,500 LF the trench had to be maintained with solid sheeting; which meant that beams had to be drilled in ahead of the excavating crew and then plates were lowered down between the beams while the trench was being excavated. This was very slow and a dangerous operation taking into account the bad soil conditions, the location of the trench in proximity to live traffic and the overall extreme depths that the sewer needed to meet.
Horizontal Directional Drilling Projects
This project is located at the Irvine Regional Park in Orange County California. The project is designed to serve existing park facilities, converting them from the existing septic sewer system, which is currently in use. The project site includes 12 restrooms, maintenance yard, horse stables, residence house, nature center, various buildings and public zoo. Irvine Regional Park Sewer Conversion, County of Orange- - Horizontal Directional Drilling Project There are two portions to this construction project, the County Park portion and the public portion. The County Park portion of the new construction includes mainline, laterals and manholes. The Public portion of new construction includes a lift station and a force main. The lift station is a 270 gallons-per-minute duplex submersible lift station consisting of two side rail submersible 20 horsepower vortex pumps. 2,290 lineal feet of 6-inch PVC forcemain and 9,870 lineal feet of 8-inch PVC gravity sewer and laterals including manholes were installed. Other aspects of the project included jacking 800 powered emergency generator, SBC and SCE service connections, demolition of the existing Irvine Regional Park submersible pumping station, abandonment of existing sewer pipes, septic tanks and disposal fields and preservation/ protection of existing trees. ExxonMobil- Horizontal Directional Drilling Project Los Angeles and Long Beach have been making adjustments to their ports in order to bring in larger ships to these areas. One of the changes taking place at the Ports of LA and Long Beach involved lowering all pipelines crossing waterways. This project for ExxonMobil required the installation of a pipeline bundle under the main channel near the East Basin in the Port of Los Angeles. ARB crews horizontally directionally drilled and installed 1800-ft. of 1-24`` and 2-10`` pipelines. The 3 pipelines were welded up separately in strings and then bundled together as the drilling rig pulled them across. Surrounded by heavy trucking and the loading and unloading of cargo containers, workspace was very limited. Anchorage Alaska- Horizontal Directional Drilling Project The HDD Group was in Alaska in 2004, on a project for the Alaska Pipeline Company`s 20-inch Beluga Transmission Pipeline Relocation Project. The project involved a horizontal directional drill under the Susitna River and the installation of 4,350-ft of 20-inch pipe. This work was located in a very remote area west of Anchorage and the Cook Inlet in the Susitna Flats State Game Refuge. 26 miles of ice road was constructed to get to the project location. Two large fabric structures were erected on ice work pads to protect the crew and drilling equipment from sub-zero temperatures. The work was done during February and March, with temperatures ranging between minus 15 to 10 degrees Fahrenheit. The pipeline was successfully installed and the equipment and structures were demobilized before spring thaw without damage to the sensitive environment. The Port of Los Angeles- LA Department of Water and Power, Waterlines- - Horizontal Directional Drilling Project ARB, Inc. has now completed eleven large diameter horizontal directional drills in the Ports of Los Angeles and Long Beach over the last ten years. Three of these horizontal directional drills for the Port of Los Angeles were accomplished in 2004. The three most recent projects were performed under two contracts. One contract was for the installation of 3,033 feet of 36-inch steel casing with 30-inch HDPE carrier pipe for reclaimed water as well as 1,505 feet of a bundle of six 8-inch HDPE electrical conduits. A separate contract called for the installation of 2,645 feet of 30-inch steel casing with a 26-inch HDPE liner.
