Martin Marietta Materials Southwest, Inc.

Martin Marietta Materials Southwest, Inc., operating as Martin Marietta, is a subsidiary of Martin Marietta Materials, Inc. (a for-profit manufacturer headquartered in Raleigh, North Carolina) that supplies concrete and aggregates to federal construction projects as a subcontractor, with minimal prime contracting activity. The company operates exclusively or nearly exclusively under subcontracts to larger construction primes, with 69% of recent awards routed through sub relationships rather than as a direct prime awardee.

Martin Marietta Materials Southwest's federal work centers on concrete supply for naval facility and waterfront construction. The company has supplied concrete to Manson Construction Co on nine sub awards tied to Pier 6 replacement work at Naval Base San Diego (P443 DB CONSTRUCTION project), all dated May 26, 2022, and placed under the Waterfront MACC IV vehicle. The Navy's Naval Facilities Engineering Command accounts for 9 of 13 awards in the source data and represents the dominant customer by award count. The Department of the Army Installation Management Command Southwest Region, the Department of Agriculture Forest Service R8-Southern Region, and the Department of the Air Force Air National Guard complete the customer set. By dollar value, the Army project carries the largest single award at $98 thousand, with remaining awards tracking at $15 thousand or less.

Activity is heavily concentrated in a single procurement event: nine awards all dated May 26, 2022, represent bulk concrete supply on a single naval construction sub task. The source data spans from 2009 to 2022, but the most recent award is now more than four years old, indicating no new federal work captured in recent years. Combined potential value across all thirteen awards totals $128 thousand, with 100% obligated. The vendor's category footprint splits between heavy civil engineering construction (9 awards, bulk mineral construction materials PSC) and quarrying (2 awards in crushed limestone mining). As a subsidiary of a larger aggregates manufacturer, Martin Marietta Materials Southwest operates as a materials supplier and sub-tier resource for federal construction primes rather than as a prime systems integrator or standalone federal contractor.
