Cerrudo Services’ experience in vertical construction and renovation includes multiple task orders for the US Coast Guard, US Army Corps of Engineers, Lawrence Livermore National Laboratory, Lawrence Berkeley National Laboratory and other Government entities.
Cerrudo Services renovated the kitchens and latrines at four California National Guard (CANG) Armories in Northern California. The existing armories were constructed almost 60 years ago. CANG desired these renovations for their own personnel and to promote the rental of the armories to private groups by providing disabled access to toilet facilities and kitchens.
Kitchens were installed with new ranges and hoods with exhaust and make-up air, fire suppression system, wood cabinetry with stainless steel tops and quarry tile flooring. Concealed plumbing and electrical infrastructure were installed for sinks, refrigerators, freezers and ice makers. The Men’s and Women’s latrines were renovated with new plumbing fixtures, solid surface lavatory countertops, toilet partitions and bath accessories, exhaust fans and ceiling heaters. The finishes were upgraded with new ceramic tile wainscots, new paint on the upper walls and exposed wood beam ceilings, and new ceramic floor tile.
Cerrudo Services provided the design and construction for a new direct digital control (DDC) system for all the air handling units, and heating and cooling systems in Building 543 at the Coast Guard Training Center. The existing control system was an obsolete Honeywell 7600 DDC system and parts were no longer available for the controls.
Existing HVAC equipment in the four story building includes four air handling units (AHU), four AC condensers, six hot water circulating pumps, 110 VAV boxes with thermostats, and a hot water boiler. Smoke detectors are located in the AHU’s supply and return air ducts.
Cerrudo demolished existing equipment including all main and local controllers, work stations and furniture, wiring, all inputs and outputs, building network wiring, all control enclosures and other components associated with the existing DDC system. Work included patching and painting walls and ceilings to match the existing finish where demolition occurred.
Cerrudo provided a turnkey building automation system consisting of a single complete non-proprietary DDC for control of the heating, ventilation and air conditioning systems. The system was designed and installed so the Government can perform their own repair, replacement, upgrades and expansion of the system.
Cerrudo Services renovated 114 dormitory rooms and common areas on three floors of Horsley Hall. New carpet tile and vinyl baseboard were installed throughout. Existing doors were repaired, repainted and reinstalled. New programmable thermostats were furnished and installed. Existing light fixtures were either replaced or refurbished. All existing painted surfaces were cleaned, primed and repainted.
In the restrooms, ceramic floor and wall tile were installed. Plumbing fittings were installed on the existing vanity under-mount sinks and in the shower. A ceiling mounted exhaust fan, recessed bath heater lamp and light fixtures were installed in each restroom.
Corridors received carpet tile, hardwood base and wall panels, stainless steel chair rails, refurbished wood doors and hardware, recessed downlights, suspended fluorescent fixtures and wall-mounted sconces. TV lounges received wood wainscoting with stainless steel chair rails, and new acoustical ceiling tiles. The elevator lobbies received wood wainscoting and chair rails, and new ceramic floor tiles.
Parts of the exterior building stucco were repaired. Selected areas of exterior concrete pavements and walkways were repaired, sealed and cleaned. All exterior louvers and bug screens were cleaned.
Cerrudo Services constructed a new two story, 3,880 SF expansion of the existing Coast Guard Base Gymnasium. The new exercise areas consisted of high quality architectural finishes and energy efficient features such as occupancy controlled indirect lighting fixtures. Demolition required a significant excavation of material to accommodate the construction of the new addition. Site work included new exterior stairs, ADA compliant ramps and walkways, and associated concrete retaining walls that connected to the adjoining gymnasium.
The addition consisted of a concrete foundation with a concrete slab on grade, exterior walls with stucco finish and aluminum framed exterior windows, a second story level constructed of wood joists and plywood substrate, and a built-up elastomeric roof, all matching the existing gymnasium construction. Interior work included cabinets for storage, working space and display, suspended acoustical ceilings, and resilient exercise mat flooring. The electronically controlled heating and ventilation in the exercise rooms consisted of a ducted supply and plenum return system. New electrical items included indirect fluorescent lighting, 20 amp duplex outlets, electrical panel, controls and expansion of the fire alarm system.
Cerrudo Services provided mechanical piping for Power Plant Unit No. 6 in Redding, CA. Unit No. 6 is a steam generated boiler plant. The original contractor did not perform, and Cerrudo Services was selected to complete the project.
Cerrudo was tasked with sorting out what work had been completed and what had not, tallying the existing material inventory that was on site and determining what additional materials were needed to finish the work. The scope of work included site grading and paving, mechanical equipment installation including complete erection, assembly and alignment of the heat recovery steam generator modules and Siemens SGT-800 gas turbine generator, fabrication and installation of all the mechanical piping and valves including fuel gas piping, and instrument installation including inline devices, local gauges, impulse tubing and transmitter and stanchion mounting.
External connections, materials and equipment for the various subsystems including platforms, ladders and foundations for the turbine/generator were provided. The boiler feedwater pump and RO water treatment building was erected and HVAC installed. Electrical equipment such as transformers and the Siemens control module was installed.
Cerrudo Services constructed a new ground up fire fighting facility at a remote, undisturbed forest location. This facility consists of slab-on-grade wood frame buildings including barracks quarters, office/administration facilities and an apparatus/shop building requiring a new utility infrastructure.
The project owner requested considerable changes to the design of the facility 60 days into construction including additional support structures, additions to the original designed structures and alterations to underground utilities services. Cerrudo removed and re-routed utility lines that had already been placed and re-configured new utility lines that had yet to be placed with those that were to remain unchanged.
Cerrudo was able to continue interior work activities throughout the winter months. With the return of favorable weather, site activities were resumed including utilities, concrete walks and slabs and asphalt paving. Equipment was installed including a 2,000 gallon fuel tank, a 20,500 gallon water storage tank, a fire suppression system pump, an electrical system back-up generator and a domestic water pump system.
Cerrudo Services renovated an existing laboratory for the US Forest Service at their fire research facility in Riverside, CA. The facility performs research on the redevelopment of damaged/destroyed forest areas affected by fire and other natural disasters.
After demolition of existing conditions, construction began by erecting a new second floor over the existing single floor space incorporating multiple steel columns with below-ground spread footings and reinforcement. The second floor was built out with offices, conference rooms, and an extension to an existing corridor that provided access to an occupied section of the building. The first floor was built into an advanced laboratory to support the facility’s research. The new lab included installation of laboratory-grade steel cabinets, chemical-resistant resin counter tops, epoxy based sinks, fume hood systems with rooftop motor exhaust systems, emergency eyewash stations and a specialized gas distribution system. Access to the second floor was provided by means of a new two-stop elevator and steel stairway.
