General Contractor Assistant Jobs in Ohio (NOW HIRING)

POSITION SUMMARY

Mid-Ohio Air Conditioning (MOAC) is a design-build commercial and industrial HVAC contractor serving central Ohio. Our Construction Division self-performs mechanical projects ranging from $25,000 to $5 million for owners, general contractors, and institutional clients.

The Assistant Project Manager (APM) owns the operational execution of assigned projects under the direction of a Project Manager. This is a hands-on, field-facing role: helping to organize the start of job, coordinating manpower and equipment, driving the schedule, pricing and pushing change orders, managing subcontractors, measuring progress, and protecting job cost. The APM plays a key role in how projects actually get built through supporting the peripheral items that make projects successful and allowing project managers to focus on project milestones.

This position is intentionally structured as the development path to Project Manager at MOAC. An APM who performs is expected to take full P&L ownership of small projects within 12 months and to progress to Project Manager within 18 to 36 months. Career progression milestones are defined in this document. APMs also participate in and have impact to the continuous improvement process at MOAC.

ESSENTIAL DUTIES & RESPONSIBILITIES

Project Execution & Field Operations

• Manage day-to-day operational execution of assigned projects under the direction of the Project Manager, including small projects assigned for independent ownership as skill develops.
• Develop and maintain project schedules; coordinate MOAC scope with general contractor milestones, other trades, and owner-driven constraints.
• Coordinate manpower requirements with Operations and field leadership — forecast crew size, skill mix, and duration by phase, and communicate changes early.
• Visit jobsites regularly to verify installed work against drawings, monitor productivity, identify field issues, and support foremen with the information and materials they need.
• Lead or attend jobsite coordination meetings, pre-installation meetings, and owner/GC progress meetings; represent MOAC professionally.
• Identify and resolve field conflicts, coordination clashes, and constructability issues before they become schedule or cost impacts.
• Support job-specific safety expectations in partnership with Meriton Safety; confirm crews have required equipment, task-specific plans, and site orientations.
• Drive punch list completion, system startup, testing and balancing coordination, commissioning support, and owner training scheduling.
• Maintain project logs and trackers — submittal log, RFI log, change order log, equipment delivery log — and keep them current without prompting.
• Distribute drawing revisions, addenda, and specification updates to the project team and field crews, and confirm the field is working from current documents.

Buyout, Procurement & Subcontractor Management

• Assist with procurement and project buyout: convert the estimate into committed costs through equipment releases, material purchases, and subcontract agreements.
• Review and negotiate vendor and subcontractor pricing as directed; confirm scope alignment against contract documents before commitment.
• Define scopes of work for subcontracted trades and manage subcontractor performance, schedule adherence, and quality in the field.
• Determine equipment and material requirements, quantities, and delivery sequencing;
• Review submittals and shop drawings for technical conformance with plans, specifications, and design intent prior to transmittal.
• Manage long-lead equipment risk — identify exposure early, evaluate alternates, and escalate schedule impacts.

Cost Control & Financial Performance

• Track committed cost, labor hours, and productivity against the estimate.
• Based on project progress and input from project managers, prepare monthly cost-to-complete projections and percent-complete inputs in the ERP software for review with the Project Manager and division leadership.
• Identify cost variances early, determine root cause, and recommend corrective action rather than reporting the variance after the fact.
• Price change orders and time-and-material work; prepare pricing backup, negotiate with the general contractor or owner, and pursue approval to execution.
• Under direction of the project manager, identify out-of-scope work in the field and convert it to approved, billable change orders — no scope performed without authorization.
• Review labor time entries and job cost coding for accuracy; correct miscoded cost before month-end close.
• Report accurate percent complete assessments in work in process (WIP) meetings to promote accurate monthly progress billings.

Contract & Technical Administration

• Read and apply contract documents, plans, specifications, and mechanical drawings; understand MOAC's scope, exclusions, and contractual obligations on each project.
• Prepare and issue RFIs on technical questions and evaluate responses for cost and schedule impact.
• Maintain awareness of notice requirements, delay documentation, and contractual deadlines; escalate contract issues to the Project Manager promptly.
• Support permitting and inspection coordination with authorities having jurisdiction.
• Provide technical directions to the Project Coordinator on project setup, cost coding structure, and closeout requirements.

Customer & Team Relationships

• Serve as an operational point of contact for general contractors, owners, engineers, and subcontractors on assigned projects.
• Communicate proactively — deliver bad news early with a recommended solution rather than late with an explanation.
• Build relationships with field leadership and earn credibility with crews through preparation, responsiveness, and follow-through.
• Support the estimating and sales team with constructability input, budget pricing assistance, and lessons learned from completed work.
• Perform other duties as assigned in support of Construction Division goals.
