Miller & Long

What Miller & Long does

Miller & Long Co., Inc. is a privately held, self-performing structural concrete subcontractor founded in 1947 and headquartered in Bethesda, Maryland. The company delivers turn-key concrete construction services — preconstruction, formwork installation, hoisting, rigging, concrete conveyance and pumping, concrete finishing, and tower crane erection and dismantling — for general contractors, real estate developers, and commercial building owners across the Mid-Atlantic (Washington D.C., Maryland, Virginia). Project portfolio spans mixed-use, residential towers, office buildings, institutional/medical/laboratory facilities, parking garages, and sports stadiums, with notable credentials including the Capital One Headquarters (103,000 cubic yards, LEED Gold), The Wharf Campus (peaking at 450 workers and 3,000+ cubic yards per week), Capital Crossing, and Reston Station.

The technical stack is built around in-house equipment and labor rather than licensed platforms. Core capabilities include proprietary sustainable concrete mix designs achieving a 50% embodied carbon reduction versus NRMCA baseline (integrated with CarbonCure technology), VDC/BIM using Revit with MEP and crane modeling, ASA-certified shotcrete application, portable and on-site batch plants producing 200+ cubic yards per hour, and a 27+ acre equipment yard (Jack Miller Yard) housing owned tower cranes, mobile cranes, mixer trucks, concrete pumps, and supporting logistics. A wholly-owned D.C. Certified Business Enterprise subsidiary (Miller & Long DC, Inc., founded 2011) handles set-aside-eligible Washington work, and an NCCER-accredited apprenticeship program (100+ graduates) supplies the skilled-trade pipeline. Technology integrations are limited to CarbonCure chemistry and BIM tooling; no AI/ML or API products are disclosed.

Revenue is project-based, earned through competitive bidding against fixed-price or cost-plus contracts with general contractors and developers. Pricing is individually negotiated per project with no public disclosure. The go-to-market motion is sales-led and relationship-driven, anchored by multi-decade tenures with named developers (Carr Properties, Boston Properties, Brookfield Properties, Douglas Development, Stonebridge, JBG Smith, Hoffman & Associates) and top GCs (Clark Construction, Balfour Beatty, Whiting-Turner, DAVIS, HITT Contracting, Donohoe Construction Company). Marketing is primarily earned through project delivery, industry awards, and LinkedIn/Instagram presence rather than paid acquisition, and geographic scope remains regional within the Mid-Atlantic.
