Preconstruction Estimator

For over 100 years, Maguire has been a leader in the construction, maintenance, and rehabilitation of water storage tanks and elevated water towers. As communities continue to invest in critical water infrastructure, Maguire is investing in the next generation of preconstruction professionals who help shape project success long before construction begins.

Maguire is seeking a highly driven Preconstruction Estimator to lead the planning, estimating, risk evaluation, and preconstruction efforts for municipal and industrial water storage tank projects across North America.

As Maguire transitions from a traditional estimating department to a strategic Preconstruction Department, this role will play a critical role in how projects are pursued, priced, planned, and ultimately executed. The successful candidate will work alongside operations, project management, sales, business development, engineering firms, subcontractors, and customers to ensure every project begins with a solid foundation.

This position is ideal for someone who enjoys solving complex challenges, influencing project strategy, identifying risk before it becomes costly, and leveraging innovative technology and AI-powered tools to drive better decisions.

At Maguire, we believe successful projects are won and planned before they are built.

Our Preconstruction Department exists to provide certainty, accuracy, and confidence throughout the project development process. We combine industry expertise, historical cost data, construction knowledge, and AI-powered estimating technology to deliver smarter project planning and stronger project outcomes.

The Preconstruction Estimator serves as the bridge between business development, engineering, operations, and project management, helping ensure that every project is:

• Properly scoped
• Accurately priced
• Carefully planned
• Fully understood
• Strategically positioned for execution

• Lead all preconstruction activities for new water storage tank construction opportunities.
• Develop complete and competitive project estimates from bid inception through project handoff.
• Review plans, specifications, geotechnical reports, site conditions, contracts, and bid documentation.
• Identify project risks, constructability concerns, scope gaps, schedule challenges, and pricing exposures.
• Develop estimating strategies that support profitability, quality, safety, customer satisfaction, and successful project execution.
• Participate in pre-bid meetings, site visits, customer meetings, and internal strategy sessions.
• Challenge engineers, owners, and stakeholders when project requirements appear unclear, incomplete, inconsistent, or unnecessarily risky.

• Perform quantity takeoffs, labor analyses, equipment evaluations, material estimates, and subcontractor scope reviews.
• Develop cost models that accurately reflect project requirements and market conditions.
• Utilize historical project data and production information to improve estimating accuracy.
• Prepare estimate summaries, bid reviews, risk assessments, schedules, and executive recommendations.
• Analyze actual project performance data to continuously refine future estimating assumptions.

Maguire is actively investing in artificial intelligence to strengthen and accelerate the preconstruction process.

The Preconstruction Estimator will leverage AI-powered estimating agents that assist with:

• Specification analysis
• Drawing review
• Quantity validation
• Bid compliance verification
• Risk identification
• Scope comparisons
• Historical project analysis
• Proposal development
• Subcontractor quote evaluation
• Preconstruction documentation

These tools allow our preconstruction professionals to spend less time on administrative review and more time on strategic decision-making, risk management, customer engagement, and project planning.

While AI enhances the process, the Preconstruction Estimator maintains full ownership and accountability for the accuracy, completeness, and execution readiness of every estimate.

• Solicit, evaluate, level, and negotiate subcontractor and supplier proposals.
• Identify and develop relationships with new subcontractors and vendors.
• Ensure scopes are complete, competitive, and properly aligned with project requirements.
• Compare subcontractor pricing and qualifications to ensure best-value selections.

• Collaborate closely…
