Estimator II

GeoStabilization International — Westminster, CO (Denver HQ) — Estimating & Design

Location: Westminster, CO (GSI Headquarters, Denver metro)

Department: Estimating & Design

Compensation: $99,000 – $126,000 USD

Travel: Approximately 15–25% regionally for site visits and client meetings

We're hiring an Estimator II to prepare detailed, accurate cost estimates for GSI's heavy civil and geohazard mitigation projects — earthwork, formwork, reinforced concrete, shotcrete, drainage, foundations, and retaining structures — from schematic design through final construction documents. You'll own assigned trades and portions of preconstruction projects end-to-end, working closely with Operations, Superintendents, and the broader estimating team.

This is a mid-level estimating role: you'll take full ownership of the estimates assigned to you, from takeoff through final pricing, while supporting more senior estimators on larger or more complex pursuits.

• Review drawings and specifications from contract documents (RFPs, specs) to determine quantities and calculate pricing.
• Communicate with subcontractors and suppliers to solicit and obtain pricing for projects.
• Communicate with owners to clarify scope of work for assigned projects through the RFQ process and interfacing with Project Development Engineers, as well as with clients.
• Determine material quantities across various scopes of work such as soil nail walls, anchored tieback systems, pinned mesh slope stabilization systems, micropiles, and other geohazard mitigation-related service lines.
• Attend pre-bid meetings and site visits to assess site conditions, conduct time-studies, or to gather operational data points for future estimates as needed.
• Solicit and review subcontractor bids for completeness, scope, and pricing.
• Review drawings and specifications to identify risk factors early in the pre-construction process, as well as through interfacing with Operations, Project Management, Procurement, and Executive personnel where necessary in the project lifecycle.
• Communicate with team members regarding scope, pricing, and construction details.
• Perform detailed takeoffs for self-performed work and price assigned trades.
• Provide complete estimates on assigned trades.
• Apply best-practice estimating principles from highly-conceptual Rough-Order-of-Magnitude (ROM) estimates through to detailed, construction-ready project proposals.
• Participate in presentations to owners, regulatory/oversight authorities, and/or other stakeholders as needed.
• Support subcontractor and supplier buyout for assigned trades.
• Identify opportunities to improve project cost or efficiency and share suggestions with the team.

• 5+ years of construction estimating experience.
• Strong verbal and written communication skills, with the ability to communicate effectively with subcontractors, owners, and team members.
• Working knowledge of heavy civil construction, including earthwork, formwork, reinforced concrete, shotcrete, drainage, foundations, and retaining structures.
• Familiarity with construction management, architecture, or engineering.
• Working knowledge of the trades involved in estimating and constructing heavy civil infrastructure, including how scopes of work fit together.
• Ability to create and deliver presentations.
• Ability to work additional hours as needed to meet project deadlines.
• Valid driver's license.
• Working knowledge of MS Office and Excel.

• Knowledge of the construction drilling industry.
• Experience with estimating software (B2W preferred; HCSS HeavyBid, Bluebeam, or Excel also useful).

• Ability to conduct site visits on uneven, sloped, or remote terrain.
• Combination of office-based estimating work and field site assessments.
• Approximately 15–25% travel within the region for site visits and client meetings.

• Exercise honesty, integrity, and respect with all clients and co-workers.
• Maintain a professional appearance and demeanor, with a positive attitude.
• Communicate effectively with co-workers and clients.
• Work with accuracy, efficiency, and attention to detail.
• Maintain good attendance and work safely in compliance with all safety policies.
• Respect the work environment and keep it as neat and clean as possible.
• Exercise initiative to learn new skills and help co-workers when possible.

• Great medical, dental, and vision insurance options with additional programs available when enrolled.
• Mental health benefits.
• 401(k) plan to help save for your future, including company match.
• In addition to 7 observed holidays, salaried team members have flexible paid time off.
• Paid parental leave.
