Senior Estimator

Blueline Associates, Inc. is a premier commercial general contractor and construction management firm based in the East Bay. We specialize in high-end commercial tenant improvements, including office, laboratory, clean-room, medical, life sciences, and industrial facilities.

Our clients include some of Northern California’s most recognized companies, and we are known for precision estimating, collaborative delivery, and a culture that embraces innovation and technology.

We are seeking a high-level Estimator with deep expertise in commercial TI construction to join our team. This position is open now — we are actively interviewing and will move quickly with the right candidate.

This is a critical, high-impact role that directly influences our ability to win work, protect margin, and scale the business.

The ideal candidate is:

• Highly experienced in commercial TI estimating
• A STACK power user
• Fluent in AI tools

You will own the full estimating lifecycle — from early budgets through final bid — and serve as a key partner to our Managing Directors and Project Management team.

This is not a traditional estimating position.

• Operates at a high level — you don’t just price jobs, you are an important member of the collaborative team who helps win them
• Is a true STACK expert — fast, accurate, and constantly refining your assemblies and workflows
• Actively uses AI in your day-to-day work (scope review, RFIs, document analysis, cost validation, etc.) while understanding its limitations and validating as needed.
• Understands commercial TI inside and out — office, lab, medical, R&D, industrial, and retail
• Builds and maintains strong relationships with subs, architects, and construction partners

• Lead all phases of estimating for commercial TI projects (concept through GMP/lump sum)
• Perform detailed takeoffs and cost analysis using STACK (expert level required)
• Maintain and continuously improve STACK assemblies, templates, and cost libraries
• Leverage AI tools to accelerate document review, scope analysis, and estimate accuracy
• Identify scope gaps, risks, and constructability issues early in the process
• Work with PMs to develop RFIs and clarifications to ensure complete and competitive bids
• Help manage subcontractor bid coverage; solicit, scope, and level bids
• Prepare detailed budgets by trade division and internal cost models
• Deliver clean, complete turnover estimates to Project Management
• Collaborate with PMs and field teams to refine assumptions and improve future estimates
• Maintain cost history, pricing data, and benchmarking systems

• 5–10 years estimating experience with a commercial GC focused on TI/interiors
• Expert-level proficiency in STACK (required)
• Active use of AI tools in a professional workflow
• Strong experience with commercial office, lab, medical, or life sciences TI projects
• Deep understanding of CSI divisions and trade scoping
• Excellent communication skills and ability to present/defend estimatesanalysis
