Precast Concrete Foundation – Hexa-Con

Project Details

This project was a supply contract to the US Marine Corp to provide 3 precast concrete foundation systems to be used to support several 200 foot tall communication towers at various locations throughout the southwest US including, California and Arizona for the Land Mobile Enterprise Radio System. To resist high overturning loads, some towers are double layered and the weight of the foundation can exceed 1,000,000 lbs.

The hexagon naturally occurs in nature and has been used throughout the past for its durability and functionality. Pre-Con has remodeled this fundamental shape to create a revolutionary foundation system suited for remote construction sites or locations where excavation is difficult. This unique design:
  • Is scalable in size, thickness and capacity.
  • Is modular and can be disassembled and relocated.
  • Can be assembled above or below ground.
  • Can be considered as equipment under certain conditions.
  • Can be quickly assembled for rapid deployment.
  • Is capable of withstanding harsh environments.
  • Does not require excavation.
The system functions by conjoining multiple pre-fabricated hexagon blocks into patterns, which are post-tensioned into one large foundation with the strength of a continuous concrete foundation.

Gas Line Repair

Project Description

Repair and replacement of natural gas distribution system at Point Mugu, Naval Base Ventura County. A total of 31,228 ft, or 5.91 miles of gas line, 70 gas meters, and 126 regualtors were installed. Additionally, 33 gas vaults were demolished.

How We Accomplished It

Directional Drilling was the main method to place the gas line throughout the complex. It increased speed and removed the need to trench, allowing for significantly lower impact to the environment and smaller construction footprint.

Evaluator Remarks

This has been my fourth project with Pre-Con Products and for the fourth time, they deserve nothing less than an Outstanding. Pre-Con consistently finishes projects ahead of time and provides extra work, at no cost to the Government.

Such items include:

*Patched a large hole in the street with Asphalt in Phase 5 Housing.

*Patched a section 2′ X 10′ at Ave. C and 6th Street, that was sunken in.

*Ran a communication conduit for the customer and SC Gas from outside gate 1 to inside of the gate. SC Gas would not begin work on the gas lines until this was completed. It required two personnel and a back hoe; one working day + materials.

*Demolished 24 vaults on phase 4, at no charge after the contract amount of 15.

*Purging Ordinance area approx. 8,000′ to 10,000′ and cutting risers. (Plus matching existing) Ordinance area was taken out of our contract. Contractor has been doing this for safety and although they were not required to do so, they felt a moral obligation to, as it would not have been right to leave gas in an abandoned line.

*A lot of trouble shooting on phase three. Before Allied came back into the picture.

Where other contractors stand-by for the Government’s response to approach an obstacle, Pre-Con is proactive by providing recommendations and timely estimates to overcome them. Pre-Con makes the modification process trivial, as they always fall well under the IGE and provide accurate revised schedules.

You seldom see contractors like Pre-Con.

They genuinely care about their product and serving the Navy. It has been an absolute pleasure working with Pre-Con Products. They understand and reflect the Seabee “Can Do” spirit, by overcoming obstacles to meet the mission; not strictly for a paycheck.

Contractor Remarks: Pre-Con concurs with Evaluation of the Navy and would like to congratulate NAVFAC/Ventura for approaching this project with a true sense of partnership. The scope of work and time frame for the project truly presented the Navy and Pre-Con with an almost impossible challenge. Fortunately we came together as a team and successfully exceeded all expectations. Whenever Pre-Con encountered a changed condition or unforeseen difficulty, David No, Chief Melendez and the staff at the Navy always sought the best way forward to the benefit of all concerned participants. The close cooperation between the Navy and Pre-Con promoted a sense of mutual trust which led to the best solutions to complex problems. This project should be treated as a MODEL project for all future Contracting Officers for the Navy.

Demolition

Project Description

Pre-Con has performed three demolition projects for the US navy including the abatement and demolition of over 47 structures and removal of 4000 ft of 30″ steel water line.  The work was performed on three different project sites, including San Nicolas Island, Point Mugu Air station and Port Hueneme. Much of the work was performed in environmentally sensitive, high security, high traffic areas and at water front locations.

Pre-Con employees worked closely with the base biologist to protect the endangered Night Lizard. Pictured above, a mother lizard with her infant were extracted from the site before demolition.

Included in one of the three demolition projects was the construction of a pre-engineered building and attached storage structure at Port Hueneme. The building was constructed for the Seabee school.

Pre-Con products was able to achieve a recycling rate of over 95% for all three projects. Concrete rubble from the project was transformed into a usable crushed misc. base material and was provided to the Navy and other contractors to be used on the Navy Base for roadway repair.

Contract N6247309C1822

The main reason this project worked out so well was because of the partnering efforts between Pre-Con and the Government. We were presented with several logistical roadblocks early on in the project, but collectively came up with several contingency plans. The plan was to proceed as normal and only deviate if the need arose, which it could have numerous times. Thankfully, all went smoothly and Pre-Con was able to complete the work well ahead of schedule with little to no impact to the schedule. The primary roadblocks presented were barging and berthing. These two aspects can bring any job to a halt when dealing with the unique logistics of San Nicolas Island.

Contract N6247309C0024

Pre-Con has shown that they earned the rating by not only being within budget, on time, with no safety mishaps, and no violations, but also with all the extra effort and work they put into this project. Pre-Con has performed much additional work at no extra cost. Such work included additional concrete around the PEB building (PHl44l) and disposal of existing fractured concrete north of the PEB building. Pre-Con has also provided asphalt as infill instead of gravel at BLDG PH425. There was also a drainage problem at BLDG PH8 that was resolved by increasing pavement overlay to reduce storm water ponding between the construction site and the adjacent roadway. Pre-Con also removed and recycled approximately 60 tons of broken concrete waste from the NCTC site and provided an electrical capacity upgrade for future expansions. Pre-con has also relocated seven concrete parking bumpers and installed two additional bollards inside the fenced area of the PEB. Furthermore, Pre-con cleaned out trash, chairs, and desks that were dumped at BLDG PH425 after the contract was awarded. Pre-con has masterfully performed this project and has earned the rating of outstanding.

Contract: N6247309C1819

I have had the privilege to work with Pre-Con Products staff (Kim Pinto, Chris Nestlerode, Mike McHenry, and David Zarraonandia) and they have been the most knowledgeable, thorough, and pleasant professionals! As far as I’m concerned, they are the most outstanding contractors thus far! They have the knowledge and the experience to raise the issues and get them resolved prior to start of any work in order to prevent rework, saving Navy time and money. Look forward to another opportunity to work with them in the near future!

Runway Repair, Point Mugu, NBVC, CA

Project Description

This project included resurfacing over 400,000 square feet of asphalt paving, replacing concrete taxi ways, repairing concrete spalls on the runway and taxi ways, resealing over seven miles of construction joints and rebuilding several underground electrical vaults. The work was done on an active military airport during flight operations.

Most of the work, including concrete replacement and resurfacing, took place during flight operations.

Work on an airfield requires an experienced and conscientious crew. Pre-Con’s president and supervisor for this project is a licensed pilot and very aware of the special consideration required while working on an active flight line. Sloppy work or careless behavior can lead to a catastrophic failure.

Pre-Con worked closely with the tower and airport manager to coordinate traffic flow and taxi way closures to avoid any interference with flight operations. Extra care was taken to insure the airfield was left clean and free of FOD (Foreign Object Debris).

Remarks from the Navy

Pre-Con has finished this project on time, on budget, with no safety mishaps, and zero violations. However, this was not the cause of earning the rating of outstanding; it is the no additional cost of work that they performed. Pre-Con has repaired a number of potholes along the shoulder of the taxiway and runway, not to mention resurfacing several pavement trip hazards near the fire station. They also removed and replaced damage to a taxiway caused by malfunctioning landing gear on taxing aircraft.

Pre-Con has also introduced an advanced type of concrete that settles quicker. They took it upon themselves to coordinate with the product manufacturer to provide a demonstration of the product to repair a number of spalls on the runway. Pre-Con has also done additional work at the Attack hangar by replacing a small section of concrete on the apron that was too large for small repair.

Additional work performed includes repairing a rumble strip at the airfield entrance and widening the asphalt replacement area at taxiway C-1, C02, and the intersection of Charlie and Runway 3-21. On the following taxiways and intersection mentioned, Pre-Con provided a clean sawcut at the concrete and asphalt joint line. Pre-Con did extra grinding at the east end of taxiway Charlie. The original grind are was surveyed at 300 sq ft, but the actual grind area was over 1500 sq ft. Pre-Con did the grinding over the weekend to avoid interference with carrier qualifications and other airfield operations that are vital to the Navy’s mission.

All of the items were provided free of charge not because Pre-Con was asked or required, but because it was the right thing to do and it provided higher level of service to the customer.
Individuals and subcontractors are rarely mentioned in a CCAST report, but Mr. Chris Nestlerode and MCN construction Inc. were the solid foundation of this project. Mr. Nestlerode was the superintendent for the project and provided exceptional service to both Pre-Con and the US Navy by juggling many variables that involved this project. MCN Construction Inc. afforded Pre-Con with additional depth and insight.

Pre-Con has gone above their contract requirements and are of few contractors that understand the Navy’s mission. Their work shows how enthusiastic and motivated they are.
