The Miller / Hull Partnership, LLP

The Miller / Hull Partnership, LLP, a for-profit architecture and engineering firm based in Seattle, Washington, operates as a prime contractor (100% of recent awards) on federal design, planning, and construction management projects for civilian agencies, with no set-aside designations across its portfolio.

The firm's customer concentration centers on the Department of State Bureau of Overseas Building Operations (22 awards, $624.1 million combined potential value) and the General Services Administration Public Buildings Service (5 awards, $167.5 million combined potential value), together accounting for the vast majority of the firm's federal workload. The two rankings align closely on dollar concentration — State BOBO dominates both by volume and by value — though GSA's ranking reflects both a single-award IDIQ vehicle and multiple task orders issued under it. The Department of Homeland Security Customs and Border Protection represents a secondary customer (3 awards, $61.2 million potential value), while the Department of Interior and Food and Drug Administration round out the active agency set.

The Miller / Hull Partnership holds two primary IDIQ vehicles anchoring its federal delivery: a $125 million single-award GSA Public Buildings Service indefinite-delivery contract covering architect and engineer services across Zone C (14 western U.S. states), awarded September 22, 2023, through September 21, 2026; and a $250 million multiple-award Department of State Worldwide Design Services IDIQ for overseas facility work. Recent task orders under the GSA vehicle include a $509,641.98 delivery order issued May 19, 2026, for three design projects at the Federal Building & Courthouse in Honolulu, Hawaii (pavilion fire damage repairs, turret facade work, and waterproofing planters); a $368,165.18 order issued June 22, 2026, for architect-engineer services to design roofing systems and waterproofing at the Richard H. Chambers Courthouse in Pasadena, California; and a $388,264.40 construction-management delivery order from U.S. Customs and Border Protection (April 10, 2026) for canopy construction in Nogales, Arizona. Under the State BOBO IDIQ, the firm has delivered a $3.599 million project-development and design order for the Baghdad Embassy Compound power plant study (awarded June 7, 2022, completing November 30, 2025) and a $2.359 million order for project development and design services supporting technical due diligence for a new embassy compound site in Banjul, The Gambia (awarded September 24, 2022, completing March 22, 2027). The firm also completed planning and feasibility work for State BOBO in Munich, Germany ($793,487, completed September 25, 2026) and Perth, Australia ($1.533 million, completing September 23, 2027). Secondary work includes Food and Drug Administration orders for seismic retrofit design at its Irvine laboratory ($217,919.11, completed August 1, 2025) and laboratory room design ($135,949.29, completed October 31, 2025).

The firm's portfolio spans 42 prime awards with $853.9 million combined potential value since 1994, though activity has remained modest in recent years—two to three awards per year from 2022 through 2026. Seven awards (combined potential value $27 million) face ultimate completion within the next twenty-four months and therefore represent recompete exposure. The firm's work is categorized primarily under NAICS 541310 (Architectural Services) across 36 awards, with PSC coding split between Architect and Engineering—General (Landscaping, Interior Layout, and Designing) for 22 awards and other architect-and-engineering general categories for the remainder. SCI-reported invoiced revenue across federal service contracts above the $150,000 reporting threshold totaled $12.2 million from FY2022 through FY2024 (FY2022: $7.1 million, FY2023: $3.1 million, FY2024: $2.1 million), with median government-paid hourly rates around $639/hr and subcontract engagement averaging 46% of total contractor hours across prime records, supported by a roster of 31 named subcontractors. The firm does not appear in the source as a subcontractor to other federal primes.
