About Nan Inc.

Written by GovTribe AI ·

Nan Inc., doing business as Ocean House Builders, is a minority-owned, Asian-Pacific American construction firm headquartered in Honolulu, Hawaii that delivers military design-build and design-bid-build construction, waterfront infrastructure repair, and facilities modernization services to the Department of Defense as a prime contractor on unrestricted federal vehicles. The company operates predominantly as a prime (99% of awards) without reliance on set-aside designations, competing on commercial viability and technical qualifications across full-and-open procurements.

Nan Inc.'s customer concentration is heavily weighted toward Naval Facilities Engineering Command — the top customer by potential value with 45 awards carrying a combined ceiling of $53.16 billion — and the Department of the Army, which accounts for a substantial volume of smaller maintenance and repair task orders. The Army Corps of Engineers Engineering District Honolulu ranks second by potential value with 40 awards worth $2 billion combined. This concentration reflects Nan Inc.'s strategic positioning in the Pacific theater: the vendor holds multiple large IDIQ vehicles that anchor its pipeline to defense agencies with infrastructure responsibilities at Joint Base Pearl Harbor-Hickam, Andersen Air Force Base Guam, Fort Shafter, Marine Corps Base Hawaii, U.S. Army Garrison Kwajalein Atoll in the Marshall Islands, and Wake Island. Representative prime awards include a $215.1 million definitive contract for the Joint Consolidated Communications Center at Andersen Air Force Base Guam (awarded August 2025), a $174.9 million delivery order for Bachelor Enlisted Quarters at Marine Corps Base Hawaii (awarded September 2023), a $134.5 million delivery order for ammunition wharf repairs at Joint Base Pearl Harbor-Hickam (awarded July 2025), and a $98.9 million delivery order for DDG-1000 ship support infrastructure upgrade at Joint Base Pearl Harbor-Hickam (awarded March 2026). These awards span design-build, design-bid-build, and definitive contract structures, all at firm fixed price with no set-aside designation.

Nan Inc.'s vehicle portfolio comprises nine active IDIQs and MACCs totaling more than $56 billion in combined ceiling value. The largest vehicles are a $15 billion Pacific Deterrence Initiative Multiple Award Construction Contract awarded September 2025 by Naval Facilities Engineering Command for Indo-Pacific infrastructure projects; a $15 billion Design-Build Multiple Award Construction Contract awarded September 2025 by Naval Facilities Engineering Command for Guam and Pacific region military construction; an $8 billion unrestricted design-build and design-bid-build contract for Hawaii and Wake Island (awarded June 2025); a $2.5 billion Facilities and Infrastructure contract for Guam and the Pacific (awarded March 2023); a $995 million Design-Build and Design-Bid-Build Waterfront MACC for Hawaii and Wake Island (awarded June 2022); a $495 million Kwajalein Design-Bid-Build MATOC for Marshall Islands construction (awarded September 2024); and a $495 million Design-Build and Design-Bid-Build contract for Hawaii construction (awarded May 2025). The top five parent vehicles (by task-order count from broader historical data) show significant Army utilization: Indefinite Delivery Contract DAPC5001D0012 carries 498 task orders, DAPC5098D0049 carries 163 task orders, and N6274299D2153 carries 160 task orders, indicating deep penetration of Army facility maintenance and repair programs alongside the Navy's large-dollar waterfront and construction work.

Activity has accelerated in recent years — five awards in 2022 to 26 in 2025 — with 15 awards (combined potential value $513.2 million) reaching ultimate completion inside the next twenty-four months and facing recompete. The vendor's category concentration reflects its core mission: industrial building construction dominates at 532 awards, followed by commercial and institutional building construction at 176 awards, and the PSC coding shows 710 awards for building maintenance, repair, and alteration, with 151 for utility maintenance.

Nan Inc. holds a subsidiary, Grace Pacific LLC, a for-profit limited liability company. In its subcontractor role, Nan Inc. delivers specialized support services: it performed Space Fence operations and maintenance Level 1 support to Lockheed Martin (awarded February 2025), logistics and civil augmentation program work at Kwajalein to Vectrus Systems (awarded October 2024), and Space Fence radar operations and maintenance services to Serco (awarded August 2024 and February 2022). These sub relationships represent a small footprint (1% of awards) and sit outside the vendor's primary construction business.

The vendor's federal contractor registration dates to 2002, and the company has executed infrastructure work across a multi-decade arc at strategic Pacific military installations. Award dates cluster from 2022 forward, reflecting recent large vehicle acquisitions and sustained utilization across defense construction programs. Nan Inc. competes without small business set-asides, holds bonding capacity sufficient for projects up to $250 million individual task order magnitude, and maintains architect-engineer staff licensed in the United States to support design-build delivery requirements.
