About Massman Construction CO.

Written by GovTribe AI ·

Massman Construction CO., a for-profit Subchapter S corporation headquartered in Overland Park, Kansas, delivers heavy civil marine construction and waterway infrastructure rehabilitation services exclusively as a prime contractor to the U.S. Army Corps of Engineers. The company competes full-and-open, without set-aside designations, across a portfolio of 176 awards spanning four decades; it operates a subsidiary, West Shore Constructors LLC, and does not perform subcontract work.

Massman's capability footprint centers on lock and dam construction, miter gate fabrication and installation, floating plant services, stoplog conversion work, scour repair, dolphin replacement, and de-watering operations across inland navigation systems. Recent definitive contracts exemplify this scope: a $22 million firm-fixed-price contract from the Army Corps of Engineers St. Louis District (June 2025) for construction of the Lock and Dam 25 Downstream Approach Guide Cell in Winfield, Missouri, with completion scheduled for September 26, 2026; an $18.6 million contract from the Corps (October 2024) to fabricate and deliver Tainter Gate 3 for Newt Graham Lock and Dam 18 in Wagoner County, Oklahoma, with completion by October 29, 2026; and a $13.9 million contract from the New Orleans District (April 2024) for the Algiers Lock Dolphin Replacement project.

Customer concentration is extreme: the Department of the Army Corps of Engineers accounts for 62 awards with $329.5 million in combined potential value (nearly 70% of total dollars), and the St. Louis District alone represents 14 awards with $93.5 million. The broader Army footprint (including non-Corps agencies) covers 76 awards; the Department of the Navy holds 7 awards. This concentration reflects Massman's long-standing operational focus on Mississippi River and McClellan-Kerr Arkansas River Navigation System infrastructure — a narrow but deep market segment.

Massman holds two major indefinite delivery contracts anchoring its parent-vehicle position: a $40 million single-award IDC for floating plant construction services awarded by the St. Louis District (July 31, 2024, running through July 30, 2029), and a $200 million multiple-award MATOC for 110-foot stoplog slot cuts conversion on the McClellan-Kerr Arkansas River Navigation System (awarded February 12, 2024, running through February 11, 2029). Task-order activity against these vehicles includes 31 orders against DACW2982C0472, 25 against DACW4373C0134, and 21 against W912P919D0008 (combined potential value $17.4 million), along with smaller vehicle sets. Recent years have shown declining award flow — one award in 2025 and one in 2026 year-to-date — against a historical average of three annually from 2022 through 2024. Within the next twenty-four months, two awards carrying $40.6 million in combined potential value reach ultimate completion, exposing that volume to recompete. Work is performed across multiple waterway locations in Missouri, Arkansas, Oklahoma, Mississippi, and Louisiana, with administrative oversight and headquarters management centered in Overland Park.
