This project is an $8.6 mil improvement project with California Polytechnic State University, located on the in the heart of the CSU San Luis Obispo campus. The intent of this project was to increase the cooling capacity of the existing central plant while providing new infrastructure for a new Center for Science building.
The improvements made to the existing Central Plant included the installation of chillers, cooling towers, various pumps and a 1.5M gallon Thermal Energy System Tank. Modifications to the electrical components were also made to the campus EMS system in order to accommodate the upgrades in the plant. With these upgrades Cal Poly plans to fulfill their heating and cooling needs throughout the campus and for future expansion.

The work involves the installation of a new sewer lift station designed to replace an existing and adjacent old sewer lift station. HPS self-performed the majority of the work which included the installation of: a 20-ft deep wet well, a duplex sewage pumps, piping, valves and; grading. The electrical and perimeter fencing were subcontracted. Contract value is $211,257.00.
Subcontracted to HPS by Lewis C. Nelson and Sons, phase two of the Mendota Federal Prison facility consists of 15 new buildings. The total contract price of $8,470,875 includes site utilities, plumbing and hydronic piping. In addition to this federal prison facility HPS Mechanical has also completed several California Sate Department of Corrections facilities, including Wasco, Corcoran II and Delano II. Due to an increase in California’s prison population, HPS sees great potential for future growth in the Correctional System market in the coming years.
This high profile project in the City of Santa Barbara called for a new $38 million Energy Center to replace the existing plant and support the expansion plans for Santa Barbara’s primary hospital services provider. As a subcontractor to McCarthy Building Companies, HPS Mechanical provided the entire domestic water piping, steam and condensate piping, fuel oil piping, medical gas piping, soft water piping, condenser piping and chilled water piping for this contract valued at $7,051,495.
HPS Mechanical was the prime contractor for the $6,424,624 Site Utilities and Plumbing bid packages for this brand new $70 million high school; one of three new high schools constructed by the Kern High School District in the last four years. With a history of several successful school projects, HPS has the experience and bonding capacity to position itself as the front runner in the multiple prime bid package system for school construction. Over the years that HPS worked with the Kern High School District, it has attained a very good working relationship with the District. Colombo Construction of Bakersfield served as construction manager.
Considered to be the largest school construction project in the state in 2005, this brand new $120 million, 530,000 sq. ft. high school was a multiple prime bid package. HPS Mechanical was the prime contractor for two phases of construction: Phase 4, consisting of plumbing for the Administration Building and Laboratory Classrooms, and Phase 7, plumbing for the Gymnasium and Support Facility. Combined contract amount was $2,909,895 with Harris Construction acting as construction manager. For its part in the successful completion of this project HPS received an appreciation award from the Clovis Unified School District.
In Oxnard, California, HPS Mechanical has worked on an addition to the existing City of Oxnard Wastewater Treatment Plant that treats sewage before it is pumped out into the ocean. Several combined sewers increase the amount of effluent during rains. The plant uses chlorination during three steps of its process:
To reduce odor in the trunk line feeding the plant, chlorine is injected into the line at various points outside the plant. This chlorine comes from inside the plant.
As it works its way through the plant the effluent is treated with additional chlorine whenever its residual chlorine content gets too low.
As the water completes its cleaning it is treated with a final dosage of chlorine. When the effluent is ready to leave the plant it is treated with sulfur dioxide to remove the chlorine from the water before being pumped into the ocean.
The City has always used tanks of chlorine gas and sulfur dioxide gas in its processes. Both of these gases are extremely toxic. The city has decided that they would prefer to store the active ingredients in stable, solid solutions and keep fewer tanks of gas for backup purposes only.
This project was to replace the existing gas cylinders with tanks that can store the chorine as Sodium Hypochlorite and the sulfur dioxide as Sodium Bisulfite. This made the plant much safer and reduced the potential liability to the surrounding community. Additionally, HPS upgraded the scrubber. The scrubber is a piece of equipment that can make the chlorine gas non-toxic in case a leak occurs at a chlorine cylinder. Even small amounts of chlorine gas can be lethal, and a plant this size uses chlorine by the tons.
Installing steam lines under existing streets on a military base where recruits marched daily presented unique challenges to HPS project planners. The construction had to be coordinated with base operations so that training could continue uninterrupted. Other concerns for base operations were how the HPS jobsite would aesthetically fit in with the base’s image, which is as clean and neat as Disneyland before it opens, and how HPS crews could potentially affect the morale of new recruits. These were not difficult goals to achieve since HPS crews are always professional and neat and equipment is kept clean, painted and maintained. Everything about the HPS operation blended nicely into the overall picture. In addition, the site was maintained to project an image of modernization rather than of a base in need of repair. By listening closely during partnering meetings HPS was able to tailor our operation to exceed the client’s requirements.
This project was another logistical challenge successfully met by HPS. The difficult task here was to install underground heating and chilling lines in a busy airport. These lines ran through existing parking lots, around terminals currently in use, and in tarmac areas where planes taxied or parked daily. Some areas needed to be open during the day so planes could take off and land, other areas needed to be opened during the night so that planes could park. Passenger areas needed to be operational at all times with minimal disturbance during peak hours. In addition, this project was undertaken with a very compressed time frame; as one of several projects in a critical path leading up to August 1996 and the Republican Convention, any changes which arose could not affect the completion date. Once again, by participating fully in partnering sessions, HPS was able to thoroughly understand the needs and phasing requirements of the owners and put in place systems to expedite changes and unforeseen conditions, As the project progressed HPS was able to preemptively identify and resolve areas of impact that had not been anticipated by the owners. Even though changes were generated in excess of $200,000, the original target completion date was made.
Tying three small water companies together into one system without disrupting service to any customers was a tall order to begin with. Adding to the complexity were a 120 day construction schedule, plus state and federal water quality requirements. Not surprisingly, all of the bids for the project came in over the funding available. As the low bidder, HPS was able to meet with the engineer and suggest cost savings to keep the project within budget while maintaining the original intent of the design. All work was done in existing streets and alleys and the project was completed on time and within budget. Total contract was $1,050,000 including subcontracting of electrical, asphalt paving, and steel tank construction.
Edwards Air Force Base is one of the busiest in the country, and because of a previous contractor’s problems making a similar system operational, they were understandably concerned about this project. HPS’s job as a subcontractor to Hensel Phelps was to install an 8” stainless steel jet fuel line double containment pipe system in the existing runway. The new line tied into existing fuel lines and HPS had to keep hangers accessible, have fuel available to filling pits and keep the runway clean for 24-hour use. In the middle of the project HPS made an extra effort to keep the construction area clean for the base’s annual air show. The total subcontract was $3,300,000 and HPS had no subcontractors on this project.
There were two key design concerns on this $920,000 project at the Marine Corps Base Camp Pendleton; a 520’ x 36” bore under Interstate 5 and railroad lines and two miles of pipe in a highly traveled street on the base. HPS redesigned the project with a value engineering proposal which added street bores but moved the pipeline out of the street. This gave the base the same end product for the same cost. The bore costs offset the savings on paving but eliminated the inconvenience of construction in a busy road. This also limited the potential for accidents, as no open trenches were in the roadway. HPS subcontracted the boring and monitored it closely to insure that no problems developed.
During this $1,030,000 re-pipe of the local juvenile facility security was a primary concern of the owner. To satisfy those concerns tool trailers were installed on the roof with no access available from inside the compound. Work crews remained on the roof the entire shift, keeping tools and materials away from the inmates. Phasing on this project was critical as a certain number of beds were required to be available at all times. While piping was being done in one wing, all other wings had to remain completely operational. HPS made design and phasing changes to meet these needs. Subcontractors were utilized for all electrical, insulation, tile and wall patching.
HPS was a subcontractor to R.J. Lanthier on this project. HPS's contract was for $170,000, with the overall project being $240,000. In making the repairs indicated in the plans, HPS discovered more leaks. HPS helped the Corps determine the scope of the problem, which the Corps is now resolving with the appropriate parties from the original contract.
HPS was the general contractor on this additional piping done in the middle of the existing hospital. HPS had to rent a chiller to keep all lines operational until all the new connections were made. HPS determined that the point of connection as designed would not work, and located a point that would. HPS was able to work with the owner to make this critical path change without delaying the project. This is a $56,000 contract.
The project is located in two main areas. Segments 1, 2, & 6 are located on Sorrento Valley Road between Carmel Mountain Road and Sorrento Valley Blvd. Segment 3, 4, 5, & Pump Station 89 are located on Roselle St. between Sorrento Valley Blvd. and Estuary Way. Work on this project includes the construction of an underground Pump Station & Emergency Storage Reservoir. Work in Segments 1 through 6 involves installation of approximately 8,670 feet of 8” to 24” sewer lines.
