Coffman Specialties, Inc. Qualifications

BNSF Railway Company

Issued: 01.22.2024

750,000 CY of Concrete Paving Annually

About Coffman Our expertise has positioned Coffman as a leader in the concrete paving industry, batching and placing more than 750,000 CY of concrete and cement-based materials annually.

WE CONSTRUCT TOP QUALITY PAVEMENT FOR HIGH-PRODUCTION PAVING PROJECTS Coffman has a long history of constructing high quality pavements throughout Southern California, including the desert environments of San Bernardino, Riverside, and Imperial counties.

Coffman Specialties, Inc. was founded in 1990. For over 33 years, owners of heavy civil infrastructure have relied on Coffman to deliver large, technically challenging projects requiring expertise in concrete paving. Our capabilities are coupled with a performance-driven reputation of providing top quality pavements on high-production paving projects. The company has a long history of constructing high quality pavements throughout Southern California, including the desert environments of San Bernardino, Riverside, and Imperial counties. Additionally, Coffman has delivered more freeway lane-miles of concrete paving throughout these counties than all other contractors combined. The company’s success is attributed to our long-standing goals of working in partnership with the owners we serve to safely deliver high quality paving projects on-time and within budget.

Coffman’s position as a leader in the concrete paving industry affords us procurement advantages that result in cost and schedule certainty.

What we do Our capabilities extend well beyond our operational expertise, and include developing concrete mix designs, raw material suitability and source selection, material manufacturing and procurement, site logistics, and control processes that ensure quality regardless of challenging environmental and site conditions.

IN-DEPTH KNOWLEDGE OF CONSTRUCTING CONCRETE PAVEMENTS IN A DESERT ENVIRONMENT Aggregate Source selection is the single most important decision to develop economical concrete mixes with the desired strength and durability characteristics. We have explored, tested, and/or sourced both coarse and fine aggregates for concrete mix designs from every commercial quarry in the region, and possess full knowledge of the aggregate characteristics unique to each source.

Concrete Mix Designs / Material Suitability

Material Manufacturing and Procurement

In addition to our comprehensive knowledge of regional aggregate sources, Coffman’s position as a leader in the concrete paving industry affords us procurement advantages that result in cost and schedule certainty including direct sales access with the major cement suppliers, and access to exclusive aggregate sources in the Barstow region. Coffman also has the ability and industry resources to process the aggregates ourselves rather than rely on quarry resources.

Site Logistics

Large paving projects require hundreds of deliveries of raw materials (coarse aggregates, fine aggregates, cement, and admixtures) to support the concrete paving operations. The materials are stockpiled for immediate use. Therefore, deliveries during paving operations are continual. A detailed plan for material handling, storage, and site logistics is necessary to ensure these deliveries largely go unnoticed. Coffman has expertise in all aspects of material handling, and the management and coordination of site logistics.

Operational Controls – Mitigating Challenging Conditions

We have completed over 35 concrete paving contracts in the Coachella Valley, Imperial Valley, and Lower Colorado River Valley. Our expertise is bolstered by our experience constructing a wide variety of pavement thicknesses including: 4” thick canal lining (AllAmerican Canal); 12-14” freeway pavement; 18-20” airfield paving; and, 24” craneways (Intermodal Yard, Glamis). All of these desert projects required stringent controls for batching, hauling, and placing a wide variety of pavement types ranging from Portland cement concrete to exotic mixes for high-heat resistant, long-life pavement used for aircraft take-off and landing pads.

Capacity The successful delivery of each project is dependent on our most important asset – our people.

500

Coffman has completed approximately 250 projects, including numerous projects in the Barstow region.

Portfolio - our work Coffman has completed approximately 250 projects as a Prime Contractor and Major Subcontractor on concrete paving projects in the southwestern U.S., including numerous projects in the Barstow region.

We have used a variety of alternative delivery methods, including designbuild, design-sequencing, best-value trade-off, and CMAR/CMGC. Essential to the success of all of these projects is effective coordination, communication, and collaboration between the design team, construction team, and the owner. We have processes to capitalize on the benefits of these delivery methods while working side-by-side with owners, designers, and regulatory agencies. These processes include: cradle-to-grave risk analysis; risk management; method analysis; value analysis; design coordination; and constructability reviews.
