21 CONSTRUCTION, INC. specializes in heavy civil infrastructure construction and site development services under NAICS 237990, which encompasses other heavy and civil engineering construction. The firm delivers turnkey solutions for public works projects, including earthmoving, grading, drainage systems, utility relocation, and site preparation for federal and state-funded infrastructure. Their technical expertise centers on compliance with federal construction standards, erosion and sediment control, and project execution in remote or environmentally sensitive areas. While specific project details are not available, their operational focus suggests proficiency in earthwork, structural backfill, and heavy equipment logistics tailored to government procurement requirements. No agency relationships can be identified due to insufficient award data. The contractor’s work history does not reveal consistent engagement with any federal, state, or local agency, and no recent contracts are available to infer patterned partnerships or mission-specific support. The company’s primary industry focus is heavy civil construction, encompassing non-building infrastructure such as roads, bridges, dams, and utility corridors. In practice, this means managing complex logistics for large-scale grading and earth retention systems, often under strict environmental and safety regulations. The firm positions itself as a niche provider for mission-critical civil works requiring precision earthwork and compliance with federal construction codes, though without certified specializations or past performance examples, their market footprint remains undefined. 21 CONSTRUCTION, INC. is a small, locally based entity structured as a 2L (small business), headquartered in Malta, Montana. The company holds no government certifications such as 8(a), HUBZone, or WOSB, and operates without a documented presence beyond its Montana location. Its government market positioning is currently undetermined due to the absence of publicly available contract history, suggesting it may be emerging or selectively pursuing opportunities in regional infrastructure programs.

Fisherman’s Terminal (FT) Entry and Exit Paving RedevelopmentThe Fishermen’s Terminal Entry Redevelopment Project will comprehensively upgrade the entry and exit drives along 19th Ave W, the demolished footprint of the Downie Building C-14, and surrounding parking areas. Existing pavement in poor condition will be milled and overlaid, with stormwater infrastructure fully replaced and expanded to divert runoff from combined sewers into dedicated storm lines, including water quality treatment on qualifying surfaces. The C-14 slab will be removed to make way for new parking spaces, green space, and pollinator habitat, potentially incorporating a stormwater treatment facility, along with a new irrigation system and enhanced landscaping in the entry median. Electric vehicle charging stations will be installed in the newly configured parking area. The project will introduce protected two-way bike lanes linking the terminal entry to the West Wall bike path and improve pedestrian access to the intersection of 21st Ave W and W Emerson Pl, as well as the King County Metro bus stop. Lighting will be upgraded throughout the new parking zones and connecting pathways, and comprehensive wayfinding signage will be added to guide pedestrians and cyclists. All work is intended to enhance multimodal access, environmental sustainability, and public safety, with the Port of Seattle as the lead agency through its Waterfront Project Management division, and primary contact information provided for project inquiries.
