Commercial Estimator at W3Global

Location: Tucson, Arizona

Employment Type: Full-Time

Work Arrangement: On-site

Department: Preconstruction / Estimating

Industry: Commercial Civil Construction

Position Summary

We are seeking an experienced Commercial Civil Construction Estimator with 4D BIM experience to join our preconstruction team.

The Estimator will develop accurate, competitive, and detailed estimates for commercial civil construction projects from conceptual design through final bid. This role combines civil estimating, 3D modeling, 4D construction sequencing, scheduling, and BIM/VDC technology to improve cost accuracy, constructability, and project planning.

The ideal candidate can translate drawings and models into quantities, costs, schedules, construction sequences, and 4D visualizations.

Primary Responsibilities

• Prepare conceptual, preliminary, detailed, and final estimates for commercial civil construction projects.
• Perform detailed quantity takeoffs from drawings, specifications, BIM models, and digital plans.
• Estimate labor, materials, equipment, subcontractor costs, and general conditions.
• Review plans, specifications, addenda, geotechnical reports, and contract documents.
• Develop bid scopes and solicit competitive subcontractor and supplier pricing.
• Analyze subcontractor/supplier proposals and prepare bid comparisons.
• Develop cost breakdowns, bid summaries, and estimating assumptions.
• Identify scope gaps, exclusions, risks, and opportunities.
• Perform value engineering and evaluate alternative construction methods.
• Coordinate estimating assumptions with project schedules and planned construction activities.
• Participate in pre-bid meetings, site walks, client meetings, and estimate reviews.
• Coordinate with project managers, superintendents, engineers, architects, BIM/VDC teams, subcontractors, and owners.
• Assist with project turnover from estimating/preconstruction to operations.

4D BIM / Construction Technology

The successful candidate will have practical experience with 4D BIM, BIM/VDC, or model-based construction sequencing.

Responsibilities May Include

• Develop or review 4D construction models by linking 3D models with project schedules.
• Integrate quantities, construction activities, and schedule information into 4D workflows.
• Use 4D visualization to evaluate construction sequencing and site logistics.
• Identify constructability conflicts and sequencing issues before construction.
• Evaluate equipment movement, material flow, access, phasing, and temporary conditions.
• Support project teams in communicating complex construction sequences through 4D visualization.
• Assist with schedule development and coordination with project controls.
• Collaborate with BIM/VDC personnel to improve the connection between estimating, scheduling, and construction operations.

Preferred Technology Experience

Experience with the following is highly desirable:

• InEight Estimate
• Synchro 4D
• Microsoft Project
• Autodesk Civil 3D
• Revit or other BIM platforms
• Bluebeam
• HCSS
• B2W
• Microsoft Excel
• Other construction estimating and project management software

Commercial Civil Project Experience

Experience Estimating Projects Such As

• Commercial site development
• Retail and shopping centers
• Office and mixed-use developments
• Industrial and manufacturing facilities
• Warehouses and distribution centers
• Hospitals and institutional facilities
• Hotels and hospitality developments
• Schools and educational facilities
• Parking lots and parking structures
• Roads and access improvements
• Underground utilities
• Water and sewer systems
• Storm drainage
• Earthwork and grading
• Concrete and site improvements
• Public/private infrastructure supporting commercial developments

Qualifications

• 5+ years of civil construction estimating experience preferred.
• Commercial civil/site development estimating experience strongly preferred.
• Strong understanding of earthwork, grading, utilities, paving, concrete, drainage, and site development.
• Demonstrated ability to perform detailed quantity takeoffs and cost analysis.
• Strong understanding of construction means, methods, productivity, and sequencing.
• Practical experience with 4D BIM, BIM/VDC, or model-based construction scheduling.
• InEight Estimate experience strongly preferred.
• Ability to read and interpret civil construction drawings and specifications.
• Strong Microsoft Excel and estimating software skills.
• Excellent analytical, organizational, and communication skills.
• Ability to manage multiple estimates and deadlines simultaneously.
• Construction Management, Civil Engineering, or related degree preferred; equivalent field experience will be considered.

Ideal Candidate

The ideal candidate is more than a traditional estimator and understands how cost, schedule, quantities, constructability, and construction sequencing work together.

Plans & Specifications → 3D Model → Quantity Takeoff → Estimate → Schedule → 4D Construction Sequence → Project Turnover

Experience working with BIM/VDC teams and using technology to improve estimating accuracy and project planning is a significant advantage.

Benefits

• Competitive benefits package
• Paid time off and holidays
• Professional development opportunities
• Opportunity to work on significant commercial civil construction projects
• Opportunity to help develop and expand 4D BIM and technology-driven preconstruction practices

Application Requirements

Please submit a resume highlighting your commercial civil estimating experience.

Candidates Should Also Provide a Brief Summary Of

• Civil estimating experience
• Types and size of commercial projects estimated
• 4D BIM experience
• BIM/VDC software used
• Scheduling software experience
