How to choose a project manager

What does a project manager do?

A construction project manager is the person who keeps your build running smoothly from start to finish. They coordinate people, schedules, materials and compliance so your project stays on track, on budget and stress-free.

What is a project manager responsible for?

A project manager is the lead contractor or PCBU (Person Conducting a Business or Undertaking), which means they’re legally responsible for everything that happens on site. Rather than juggling multiple trades yourself, you deal with one point of contact who takes care of the rest. A construction project manager is typically responsible for:

• Managing the project timeline and budget

• Coordinating architects, engineers and designers

• Complying with the Building Code and safety regulations

• Hiring and managing subcontractors and trades

• Making sure work is completed to the agreed scope and quality

• Organising materials, tools and equipment

• Managing delays, variations and unexpected issues

• Keeping you updated on progress and costs

How does a project manager stay on time and on budget?

Timing and budget are two of the biggest concerns for homeowners and for good reason. A skilled project manager plans well ahead, schedules trades in the correct order and accounts for lead times on materials.

By tracking costs, managing variations early and solving issues before they escalate, your project manager helps avoid delays and unexpected expenses. At Qualitas Builders, we take a proactive approach so small challenges don’t turn into big problems.

How does a project manager manage health and safety on site?

Health and safety is a major responsibility on any building site. Your project manager puts safety plans in place, carries out site inductions and ensures high-risk work is properly managed.

As the PCBU, they’re responsible for keeping workers, homeowners and visitors safe while ensuring all legal obligations are met. This not only protects everyone involved but also prevents costly delays caused by safety breaches.

How does a project manager coordinate subcontractors?

Most builds involve a long list of trades including plumbers, electricians, scaffolders, roofers, glaziers and more. Some projects also require specialists such as stair manufacturers, asbestos removal experts or traffic management teams.

Your project manager ensures every trade is on site at the right time, with the right information and materials. This sequencing is critical. If one trade runs late, it can affect everything that follows. Strong relationships with trusted subcontractors mean better communication, reliable workmanship and smoother progress on site.

Do I need a project manager for my renovation or new build?

If your project involves multiple trades, structural work or council approvals, professional project management is essential. Even smaller renovations can quickly become complex once timelines, compliance and subcontractors are involved.

Hiring an experienced project manager means you benefit from their expertise, industry knowledge and problem-solving skills, without having to manage the process yourself.

What are the benefits of a professional project manager?

Working with a professional project manager offers some major advantages:

• Less stress and fewer decisions for you

• Clear communication and accountability

• Better quality control and workmanship

• Faster resolution of issues on site

• Confidence that your project meets all regulations

Ultimately, it allows you to enjoy the process and focus on the exciting part, watching your home come together.

How early should a project manager be involved?

The earlier, the better. A project manager can add real value during the planning stage by offering buildability advice, identifying potential issues early and helping refine budgets and timelines.

Early involvement often prevents costly design changes later and ensures your project starts on solid ground.
