About Spiniello

Spiniello Companies is a nationally recognized infrastructure contractor with more than a century of experience delivering complex underground utility, water, wastewater, and heavy civil construction projects throughout the United States.

Founded in 1922, Spiniello is one of the few contractors that self-performs all aspects of excavation and specialty pipe rehabilitation. Our reputation has been built on technical excellence, operational execution, long-standing client relationships, and a commitment to investing in our people.

As we continue expanding throughout the Mid-Atlantic region, we are looking for experienced estimating professionals who are passionate about building the infrastructure that serves our communities.

Who This Role Is Designed For

This role is designed for a highly analytical construction professional who thrives in a fast-paced, collaborative environment and enjoys solving complex challenges before the first shovel hits the ground.

The ideal candidate has experience estimating underground utilities, heavy civil, water, wastewater, or pipeline rehabilitation projects and understands both the technical and commercial aspects of competitive bidding.

Success in this role requires sound judgment, attention to detail, strong communication skills, and the ability to manage multiple bids while working collaboratively with operations, clients, and subcontractors.

• Prepare complete bid files and supporting documentation.

Bid Management

• Participate in pre-bid meetings, site visits, client meetings, and pre-construction meetings.
• Coordinate with Project Managers and field personnel to validate labor, equipment, and production assumptions.
• Ensure estimates accurately reflect project scope, schedule, construction methods, and contractual requirements.
• Support pricing for change orders and additional work throughout project execution.

Collaboration & Continuous Improvement

• Analyze estimated versus actual project costs to improve future estimating accuracy.
• Build and maintain strong relationships with clients, subcontractors, suppliers, and internal stakeholders.
• Provide estimating expertise to project teams throughout the project lifecycle.
• Contribute to the continuous improvement of estimating processes, databases, and best practices.

Qualifications

Required

• Bachelor's degree in Construction Management, Civil Engineering, or a related field.
• Minimum of five years of construction estimating experience.
• Strong knowledge of underground utilities, pipeline rehabilitation, heavy civil construction, and open-cut installation methods.
• Expert ability to read and interpret construction drawings, specifications, and contract documents.
• Experience using HeavyBid estimating software.
• Excellent analytical, organizational, and communication skills.
• Ability to manage multiple estimates and deadlines simultaneously.

Preferred

• Previous Project Management experience.
• Business development or client‑facing experience.
