Full Time Professional Scottsdale, AZ, US

Salary Range: $ To $ Annually

TetriX Modular is a newly formed company with a bold vision for the future of construction. Serving the affordable, workforce, and military housing markets, we are building a fully integrated platform that brings design, procurement, manufacturing, and general contracting together under one roof. We believe modular construction can deliver housing with greater speed, quality, predictability, and scale, and our goal is to become the industry leader in making that integrated model a reality.

Position Summary:

This is an opportunity to shape a critical function at the ground level, influence how TetriX delivers projects, and help build a modern preconstruction model rather than inherit a fixed legacy process. The right candidate will have meaningful access to leadership, broad ownership, and the ability to turn strong ideas into company standards.

We are seeking a hands‑on Preconstruction Manager to serve as TetriX Modular’s sole preconstruction and estimating professional during this stage of the company’s growth. This person will lead the process from formal Client Solutions handoff through detailed estimating, trade engagement, bid leveling, GMP development, and transition to Operations. The role requires strong multifamily estimating judgement, a clear understanding of modular and site‑built scope interfaces, and the ability to use AI as an everyday tool for improving speed, consistency, traceability, and scope completeness.

AI will support the work as an additional reviewer and workflow accelerator, while the Preconstruction Manager remains accountable for quantities, scope ownership, pricing, risk, and all client‑facing deliverables.

Key Responsibilities:

• Own the preconstruction process from formal Client Solutions handoff through quantity takeoffs, conceptual and milestone estimates, detailed bid‑based budgets, GMP development, Pre‑90/Pre‑60/Pre‑30 readiness, NTP transition, and documented handoff to Operations.
• Use approved AI tools to review drawings, specifications, addenda, meeting records, and bidder documents; identify potential scope gaps, changes, conflicts, and missing information; and validate all AI‑generated findings against the source documents before they are used.
• Develop and validate the division of scope among factory production, transportation, crane and set activities, site construction, and module‑to‑site interfaces to prevent gaps, overlaps, and duplicated cost.
• Develop trade package strategies, engage qualified subcontractors early, issue consistent bid forms and scope verification requirements, manage bidder clarifications, coordinate formal RFIs through Procore, and maintain apples‑to‑apples bid comparisons.
• Maintain historical pricing, unit‑cost databases, ROM and estimate version histories, source documentation, assumptions, exclusions, allowances, and variance explanations so each pricing update is traceable to the decision or scope change that caused it.
• Lead value engineering analyses that preserve project requirements while identifying practical cost, schedule, constructability, and modular‑efficiency opportunities; document accepted and rejected options and their budget impacts.
• Support contract negotiations and procurement planning by carrying approved scope, pricing, qualifications, award assumptions, and risk items into the GMP, buyout strategy, and Operations handoff.
• Build, document, and continuously improve TetriX’s preconstruction standards, templates, AI‑assisted workflows, quality gates, and…
