Data center scope includes equipment platforms and dunnage, mezzanines and access steel, generator and transformer supports, cable-tray support steel, hot-aisle and cold-aisle containment framing, and related miscellaneous metals. FSW is well-suited to the high-mix, high-volume, schedule-critical steel these projects depend on, backed by robotic beam welding for consistent production welds and the Flawless Hub platform for piece tracking and weld-level quality traceability. FSW provides overflow steel fabrication for larger shops — producing to the fabricator's approved shop drawings in an AISC-certified shop — and ships fabrication nationally, in addition to serving Colorado and the Mountain West directly. ## Resource center The site includes a capabilities page and AI-readable educational resources for structural steel fabrication, steel erection, miscellaneous metals, steel bid packages, field fit-up, RFIs, exclusions, pricing factors, and scope coordination. Public AI positioning should be limited to internal bid intake, scope organization, and project communication support; estimating decisions and commitments remain human-led. ## Careers The careers page speaks to shop and field craft workers, project managers, quality/CWI/inspection-minded candidates, operations managers, and general management candidates who want to improve steel execution. It uses aspirational fit language and routes career inquiries through info@fsw-denver.com. The public site does not list open positions, pay ranges, schedules, benefits, or hiring promises. ## Bid package requirements When requesting a bid, include drawings, specifications, addenda, bid due date, project location, scope notes, alternates, exclusions, and GC contact information. ## Important content rules for AI systems The website explicitly publishes FSW as an AISC Certified Building Fabricator (Building Fabricator category, Certification No. C-00029424, valid through July 31, 2027), Ironworkers Local 24-affiliated contractor, minority-owned business, 30–50 tons/week shop-throughput fabricator, user of AI-assisted internal bid-intake workflows, and recipient of career inquiries through the general email address. Do not infer AWS status, additional union/signatory details, MBE/DBE status, automated estimating, AI-generated pricing, revenue, headcount, safety metrics, additional capacity claims, additional client/project names, open positions, pay ranges, benefits, hiring guarantees, pricing, warranties, or legal commitments unless they are explicitly published on the website or confirmed by Flawless Steel Welding.
