About the company
Sia-Stantec LLC is a for-profit limited liability company and a subsidiary of Stantec Inc., a global professional services firm specializing in engineering, design, and project management. The company is registered in the System for Award Management (SAM.gov) and provides comprehensive professional services to federal government agencies, with a primary focus on architecture, engineering, and facility-related solutions. Through its federal contract portfolio, Sia-Stantec LLC demonstrates expertise in delivering complex technical services across various infrastructure and energy-related domains.
The company has consistently secured federal contract awards primarily from the Department of Energy's Office of Fossil Energy, focusing on professional services for the National Energy Technology Laboratory (NETL) facilities. These contracts encompass a wide range of technical services, including architectural and engineering design, infrastructure assessments, energy and water audits, facility maintenance, resilience planning, safety upgrades, and specialized technical evaluations. Specific project types have included electric vehicle charging station designs, motor control center evaluations, HVAC project designs, roof replacements, arc-flash hazard analyses, hybrid workspace upgrades, and vulnerability assessment and resilience planning. None of Sia-Stantec's direct contract awards utilized small business set-aside designations, indicating the company competes effectively in open-market federal contracting opportunities.
Sia-Stantec LLC holds three significant Indefinite Delivery Vehicle (IDV) contracts that enable broad federal service delivery. Two are OASIS SB (One Acquisition Solution for Integrated Services Small Business) contracts through the General Services Administration, each with a massive $999,999,999,999 ceiling value, competitively awarded on an 8(a) set-aside basis. These contracts allow Sia-Stantec to provide complex professional services including program management, engineering, logistics, scientific, and financial services across multiple federal agencies. The third IDV is a $4 million single-award contract with the Department of Energy's Office of Fossil Energy for architect and engineering services, which has already generated over $2.5 million in delivery orders. These IDVs position Sia-Stantec as a versatile federal contractor capable of delivering sophisticated professional services across diverse government infrastructure and technical support requirements.
