Naval Air Station North Island

Project Description

Delivery Method: Design Build
Location: NASNI Coronado, CA
Value: 7 Million
Completed: February 2017

Project Overview

Located at Naval Air Station North Island (NASNI) Coronado, CA, the project objective was to design PCC pavement and AC shoulders to replace the 68-year old PCC Taxiway Bravo Two which has deteriorated due to age, exposure to the elements and newer heavier aircrafts.  Taxiway Bravo Two is one of the main taxiways at the airfield that support takeoff and landing of various types of Navy, Marine Corps and civilian aircrafts.  In order to keep the airfield operational, CSI constructed the project in two phases and maintained full communication with AirOps.

Quick Facts

  • Excavated over 32,000 CY of different material.
  • Placed approximately 11,500 CY of cement treated base.
  • Place approximately 17,700 CY Portland concrete cement.
  • Sequenced the work to keep the airfield operational.

  • Over 25,000 CY Cement Treated Base Batched on Site, Placed, Graded & Compacted.
  • 92,867 Tons of Recycled Cement Crushed on Site.
  • Over 90,000 SY of Lime Treated Stabilized Soil.
  • 42,917 Tons of Asphalt Concrete Pavement Taxiways and Shoulders.
  • 95,000 LF of Existing AC Crack Repair.
  • Schedule was accelerated to finish by Jan 1 to accommodate the Blue Angeles training schedule.

Runway 6L-24R Safety Area Improvements

Project Description

Delivery Method: Bid-Build
Location: Los Angeles, CA
Value: 25.2 Million
Partner: Griffith Company
Completed: December 2015

Project Overview

Coffman Specialties, Inc. joint ventured with Griffith Company for this major runway renovation of Runway 6R-24L at LAX Airport in Los Angeles, CA.  This included the removal of asphalt, removal of Portland concrete cement (PCC), excavation, placement of asphalt pavement, placement of Portland concrete cement, airfield electrical including edge lighting, end lighting, threshold lighting, and signage that conform to NAVAIR and FAA requirements, Contractor Quality Control Program, and foreign object debris prevention.  There was strict adherence to quality requirements for flexural strength, thickness, and smoothness.  The work was completed while airport operations remained fully operational, and time sensitive schedule performance required high production concrete batching and placing within fixed time constraints.

Quick Facts

  • Self-performed the removal of 11,000 cubic yards (CY) of Portland concrete cement (PCC).
  • Placement of 45,400 cubic yards (CY) of Portland concrete cement (PCC).

Completion Date: December 2015

Project Overview

Coffman Specialties, Inc. joint ventured with Griffith Company for the major construction of the West Apron Maintenance Area at LAX Airport in Los Angeles, CA. This project is included the removal of asphalt pavement, removal of Portland concrete cement pavement, excavation, placement of Class II aggregate base, placement of asphalt pavement, placement of Portland concrete cement, airfield electrical, Contractor Quality Control program, and foreign object debris prevention. There was strict adherence to quality requirements for flexural strength, thickness, and smoothness. The work was completed while airport operations remained fully operational, and time sensitive schedule performance required high production concrete batching and placing within fixed time constraints.

Quick Facts

  • .Self-performed the placement of 153,000 square yards (SY) of econocrete.
  • 151,000 square yards (SY) of Portland concrete cement, and the construction of storm sewer lines, water lines, sanitary sewer lines, and retaining walls.
Sky Harbor Int'l Airport - Center Runway

Sky Harbor Int’l Airport – Center Runway

Project Description

Location: Phoenix, AZ
Value: $68.5 Million
Completed: 2003

Project Overview

Less than two years after CSI rebuilt the north runway at Phoenix Sky Harbor International Airport, they were awarded the reconstruction project for the center runway of the busy, three-runway airfield. A joint venture with Ames Construction, the project entailed removal of the existing center runway and 23 taxiways.

Originally slated to be completed in multiple phases over an extended period of time, the major civil works were built in just seven months. To alleviate any inconvenience to the traveling public, strict time constraints were placed on the contract, allowing just 90 days to complete the runway and taxiways. Failure to do so meant a fee of $200,000 for every day over.

The staging plan provided, however, was defective in allowing access to the site. CSI designed a new plan and went on to complete all work in just 78 calendar days. The project earned the prestigious Build Southwest Award for Excellence in Civil Construction.

Quick Facts

  • 400,000 square yards of 19-inch PCCP.
  • 100,000 tons of asphalt.
  • 6,500 cubic yards of concrete poured per day.

Project Overview

Travis AFB is home to Air Force, Army, and Navy air units, 16,000 people and one of the largest collections of historic military aircrafts in the west. The base handles more cargo and passenger traffic than any other military air terminal in the U.S. Coffman Specialties, Inc. was awarded a contract to repair and replace two sections of the aircraft parking area known as 300 ramp, originally installed in the 1940’s. The work included demolition of the existing 300 Ramp pavements; installation of new storm drainage lines; installation of a new pavement under-drain system; replacement of the 300 Ramp pavements; and incidental related work. The project was immediately adjacent to active runways, taxiways, and aircraft parking for the 60th Air Mobility Wing, the largest in the Air Force. The airfield has been in active service since WWII. Facilities added over the years had few details about what lay beneath them. CSI successfully excavated in and around all utilities and obstructions without incident.

Quick Facts

  • The work included approximately 26,000 SY (12,300 CY) of heavy duty Portland cement concrete (PCC) pavement 17 inches thick.
  • The existing aggregate base was salvaged, processed, and stockpiled for re-use.
  • Removed concrete was salvaged, processed, and stockpiled for re-use.
  • The total quantity of material recycled was 11,600 cubic yards (CY).nes, and retaining walls.

Project Description

Delivery Method: Bid-Build
Location: Burbank, CA
Value: 4 Million
Projected Completion: April 2008

Quick Facts

  • The project included 34,000 SY (14,000 CY) of Continuously Reinforced Concrete Pavement (CRCP).
  • The heavy-duty airfield pavement was 15 inches thick.

Project Overview

The Bob Hope airport was originally opened in 1930 and served as the largest commercial airport in the Los Angeles region until 1946. Today, the airport services Glendale, Burbank, Pasadena, and the San Fernando Valley with 7 major carriers and over 70 flights per day. It is the only airport with direct rail service to downtown Los Angeles. Amid considerable opposition toward expansion of any kind, this contract was awarded to extend Taxiway D. The original contract specified a sole source for the concrete aggregate. Initial trial batches resulted in low flexural strengths. CSI’s knowledge of the local aggregates and concrete mix design resulted in an extensive trial batch program that ultimately provided the Airport Authority with high quality concrete.
