Solve Your Agency's
Critical Facility Challenges
Legacy's GSA contract provides federal agencies with an established procurement path for engineered and prefabricated structures, backed by custom engineering and an integrated project delivery process.
-
Procurement Complexity
Federal facility projects require clearly defined specifications, compliant procurement procedures, and qualified contractors. Navigating acquisition requirements can add time and complexity before a project reaches construction.
Legacy Building Solutions holds GSA MAS Contract 47QSMS26D007F under SIN 332311P – Engineered and Prefabricated Buildings and Structures. Federal agencies can use this established contract vehicle to procure eligible Legacy building solutions while working with a team experienced in government facility requirements.
-
Timeline Pressure
Mission requirements don't always align with traditional construction timelines. Agencies may need additional maintenance, training, storage, logistics, or operational space without waiting years for conventional construction.
Legacy designs, engineers, manufactures, and installs complete building systems. Controlling these critical phases helps reduce handoffs between vendors and provides greater control over scheduling, coordination, and project delivery.
-
Budget Certainty
Federal projects operate within defined budgets and acquisition requirements. Unanticipated changes, fragmented project teams, and coordination issues can affect both cost and schedule.
Legacy's vertically integrated approach brings design support, engineering, manufacturing, project management, and installation together under one team. A single point of contact helps improve coordination from initial planning through completed construction.
-
Code Compliance
Federal facilities must satisfy applicable building codes, site-specific structural requirements, and agency specifications. Complete engineering and documentation are essential to the review and approval process.
Legacy structures are custom engineered for their location and intended use, including applicable wind, snow, and seismic loads. Building systems can also accommodate specialized equipment, hanging loads, mechanical systems, doors, mezzanines, and other mission-specific requirements.
