OUR PRECONSTRUCTION SERVICES INCLUDE:
• Cost estimating, budget control, and value engineering
• Analyze alternate building systems and present findings
• Constructibility reviews
• Develop and analyze Site Logistics Plans
• Strategize and develop comprehensive and thorough bid packages

• Actively participate in all project team meetings and produce meeting note documentation
Known for expert project management, exceptional client and subcontractor relationships, and meticulous attention to detail, JTM goes beyond the traditional general contractor’s role. We aggressively manage the project budget and drive the schedule to ensure our client’s goals are achieved. Through active engagement and management—we help clients make the best decisions, closely managing costs while maximizing efficiency and always delivering excellence beyond expectation.
Initiated on day one and sustained throughout the project, ensuring excellence from start to finish.
Our top core value, with a commitment from everyone to ensure every team member returns home safely each day.
We lead the process, leveraging the collective expertise of the entire project team to maximize value.
Every decision, from preconstruction to completion, is guided by our commitment to stretch every dollar and treat the owner’s budget as our own.
JTM Construction’s focus is that our team members return home safely every night as a general contractor assumes responsibility for the care, custody, and control of each project we build. With safety a foremost priority, JTM has developed a dynamic safety management approach with a comprehensive Safety Management Program.
JTM has a comprehensive safety program that protects all employees, subcontractors, Owner personnel, site visitors, and the public on ALL of our projects. Our goal is to eliminate property damage and occupational injuries by providing a safe work environment and supporting safe work behaviours. Establishing programs that promote safe work planning and practices and providing leadership that encourages, guides, instructs, and insists upon compliance from ALL employees, subcontractors, and site visitors to ensure our documented safety policies and procedures are strictly adhered to by all. JTM has been an active member of the AGC Safety Team for more than 10 years. We make a safe workplace a top priority, and we have successfully created a safety-conscious culture at JTM.
SINCE 2015
Experience Modification Rate (EMR) substantially impacts a construction company. Insurance companies use this number to gauge the past cost of injuries and future chances of risk. The lower the EMR, the lower the worker compensation insurance premiums, which benefits the client in the form of reduced cost. JTM has an EMR of 0.60, which is significantly lower than the industry average. We have maintained an EMR of less than 1.0, which is the industry average.
JTM EXPERIENCE MODIFICATION RATE
FIVE YEAR HISTORY

OUR TEAM WORKS HARD TO ENSURE A SAFE WORKPLACE. WE’RE PROUD THAT BOTH OUR LOST-TIME INCIDENT RATE AND EMR CONSISTENTLY OUTPERFORM THE INDUSTRY AVERAGE.








The self-perform capabilities of our general contracting team are one of JTM’s most robust tools for meeting and overcoming those challenges. Our experienced crews deliver greater safety, efficiency, early and continuous cost certainty, schedule and budget control, and a higher quality of work.
By self-performing these scopes of work JTM effectively manages criticalpath items in a schedule, safety, and quality control for the entire project- all advantages that create greater value for our clients. Our craft professionals take pride in their work, which leads to a higher quality of construction and a better end product.
At JTM Construction, we are committed to fostering supplier diversity and creating opportunities for small, minority-owned, disadvantaged, veteran-owned, and local businesses in all aspects of project delivery. Our Trades Outreach Program ensures a robust and diverse supplier base, enabling equitable access to procurement opportunities and meaningful participation for underrepresented vendors. Maximizing diverse participation in everything we do is as familiar to us as maximizing quality and minimizing accidents; it’s just part of our culture.
We prioritize environmental responsibility in every project. As stewards of the environment, our integrated approach streamlines design and build decisions, reducing administration while enhancing project efficiency and quality.
Our approach includes employees, clients, trade partners, and communities. By collaborating, we ensure our clients’ goals are met with smart, sustainable solutions.




At JTM Construction, we use Building Information Modeling (BIM) to improve coordination, reduce conflicts, and streamline project delivery. By integrating 3D models early in the process, we identify and resolve potential issues before they become costly, improve system coordination, and optimize project scheduling. The result is a more efficient, collaborative process that improves cost control and building performance.
We leverage Virtual Design & Construction (VDC) to improve planning, coordination, and execution. By integrating digital models with construction workflows, we optimize logistics, detect clashes early, and enhance schedule and cost efficiency. Our in-house scanning and visualization tools provide real-time insight, reduce risk, and drive better project outcomes.
Our in-house scanning and survey capabilities deliver precise, real-time data to support accurate planning and execution. Using 3D laser scanning, we capture detailed as-built conditions to align with BIM and VDC workflows—enabling early clash detection, accurate site verification, and improved trade coordination. This reduces rework, minimizes delays, and ensures efficient, high-quality project delivery.

Construction completion is not the end of a facility’s story. It is the beginning of its operational life. Systems evolve, tenant needs shift, equipment changes, and unforeseen conditions emerge. JTM’s Construction Service Group exists to support clients in that ongoing reality, delivering responsive, construction-driven solutions that protect operations and extend the life of your facility.
We operate as a long-term partner, not a one-time contractor. Our model is built around continuity, speed, and accountability by providing practical solutions without the administrative burden of traditional project delivery.
JTM’s Service Group was created to support clients long after construction is complete, stepping in when work extends beyond what in-house maintenance or facility staff can reasonably manage.
Owners and facilities teams regularly face upgrades, tenant adjustments, deferred maintenance, insurancerelated repairs, and operational improvements that require construction expertise and coordinated execution. The Service Group fills that gap, acting as a trusted extension of the client’s team with a focused, responsive approach designed to simplify the process.
Our goal is to remain a sustained, reliable presence across the lifecycle of your facility.

Unlike traditional project structures that dissolve after completion, our leadership model emphasizes continuity and long-term familiarity with each client’s facility.
Backed by JTM’s broader construction resources, safety standards, and self-perform capabilities, the Service Group delivers both the agility of a service partner and the strength of a full-service contractor.
Whether supporting a single urgent repair or ongoing campus-based improvements, JTM Construction Service Group provides responsive solutions grounded in construction expertise and operational awareness. We remain ready to support what comes next.
Our model allows us to support virtually any service need, leveraging both self-perform capabilities and trusted trade partners who specialize in service work.

CLIENT NEED
The Populus Hotel required targeted operational improvements within an active hospitality environment where guest experience could not be compromised.

The team coordinated lighting and power installations, completed acoustical caulking, and addressed staff-identified concerns with practical, cost-conscious solutions. Clear communication and daily coordination ensured alignment with front-of-house and back-of-house activities.
All improvements were delivered efficiently with no interruption to hotel operations or guest experience.
