How much does client side project management cost?



A practical guide to how Build Success Partners prices project reviews, tendering, contract support and full project management.

One of the first questions people ask when considering independent support for their building project is: What does your service cost?

It is a fair question. Building projects involve large amounts of money, long timeframes, multiple consultants, builders, contracts, approvals and risk. Before you engage anyone, you should understand what the service may cost, what affects the fee, and when full project management may — or may not — be worth it.

Client-side project management is not a one-size-fits-all service. Some clients only need a document review before signing a building contract. Others need help with feasibility, tendering, builder selection or contract review. Others need full support from concept design through to construction, handover and defects.

This guide explains how we price our services at Build Success Partners, what affects the fee, and which option may suit different types of projects.

The Short answer to - What does it cost?

For most residential, development and light commercial projects, BSP’s services may range from:



These are guide ranges only. The right fee depends on the project, documentation quality, timing, complexity and level of involvement required.

A simple document review is very different from managing a two-year process involving feasibility, design, planning, documentation, tendering, builder appointment, construction, handover and defects.

How we calculate our fees

At its most basic level, our fee is based on the amount of work required.

We look at the tasks that need to be carried out, estimate the time involved, and apply our hourly rate. For smaller or clearly defined services, that may be a straightforward fixed fee or hourly estimate. For larger projects, we often convert the expected workload into a monthly retainer or percentage-based fee so the client has a more predictable cost.

BSP’s standard hourly rate is $220 + GST per hour.

The main factors that affect the fee include:

• the scale of the project
• the complexity of the design
• how complete or unresolved the design is
• when BSP is engaged
• the procurement method
• the type of contract being administered
• the number of consultants, builders, financiers or other stakeholders involved
• the project duration
• the location and site constraints
• the level of client involvement required
• whether regular site attendance is needed

Less resolved design usually means more questions to deal with, more coordination, more decisions during construction, and more variation risk.

Why project management pricing varies. Project management is well established in commercial construction. Large corporations routinely use specialist project managers to procure and deliver their facilities because they know they do not always have the in-house experience to manage the process themselves.

In the residential and small development space, project management has historically been used more often by high-net-worth clients or entities delivering larger, more detailed and more complex projects.

That is changing.

Residential construction has become more regulated, more specialised and more complex. Clients are also understandably cautious about builder stability, cost escalation, poor documentation, variations, delays and disputes.

A client-side project manager is not just another consultant fee. Used properly, the role is there to protect the client from poor documentation, unclear scope, weak tendering, unrealistic budgets, builder selection mistakes, avoidable variations and unmanaged construction risk.

The earlier we are involved, the more risk we can usually remove before it becomes expensive.

What full-service project management actually includes

Full-service project management is not just attending site meetings.

Depending on the project, it can include:

• coordinating designers, architects, engineers, surveyors, building surveyors and other consultants
• managing council, authority and utility issues
• helping prepare or review tender documents
• liaising with builders, suppliers and subcontractors
• resolving design questions before and during construction
• assisting with financier requirements and progress claims
• reviewing progress claims
• assessing variations
• monitoring programme and delay claims
• tracking budget against actual cost
• managing project correspondence and key decisions
• managing defects, handover and final reconciliation

Full end-to-end project management usually offers the best value because we are involved from the outset. That means we can have the greatest impact on the design, documentation, budget, procurement strategy and builder-selection process before expensive commitments are made.

When we are engaged early, we can help the client avoid delays, reduce redesign, improve tender clarity, challenge unrealistic allowances, identify documentation gaps, and limit the design changes and variations that often appear later when the project is already under contract.

Late involvement can still be valuable, but it is usually more reactive. By that stage, the design may already be locked in, the builder may already have priced the work, and the client may have lost much of their negotiating leverage.

Practical construction contract review

This service is for clients who have already selected a builder and have been issued a building contract for review before signing.

Our role is not to provide legal advice. If you need legal advice on the contract terms, you should speak with a construction lawyer. Our role is different.

A legal review looks at the contract as a legal document.

Our review looks at the contract as a building project.

We review the contract from a practical construction and project delivery perspective.

That means we look at whether the contract, drawings, specifications, quotes, allowances, schedules and supporting documents all line up with what the client believes they are getting.

In many cases, the biggest risk is not the legal wording itself. The bigger risk is that the contract documents are incomplete, inconsistent or unclear.

That can lead to arguments later about whether something was included, excluded, allowed for or assumed.

As part of this review, we typically look at:

• whether all relevant design documents are properly referenced in the contract
• whether the builder’s scope matches the drawings, selections and client expectations
• whether there are gaps or unclear items that could become variations later
• whether allowances, provisional sums and prime cost items appear realistic
• whether the builder’s construction period appears reasonable
• whether inclement weather allowances are realistic for the project
• whether liquidated damages are included and whether they appear adequate from a practical risk perspective
• whether exclusions have been clearly identified
• whether there are inconsistencies between the contract, quote, plans, engineering, specifications and selections
• whether anything important has been discussed but not properly documented

The purpose is simple: to help the client understand what they are about to sign, what may still be unclear, and where the contract documents may leave room for cost increases, disputes or variations later.

This is not about creating conflict with the builder. It is about making sure everyone is clear before the contract is signed,  which is the cheapest time to fix gaps. Good builders welcome this thorough client input.

Why full end-to-end project management is priced against GRV

For full end-to-end project management, our fee is typically calculated at 4% + GST of the project’s gross realisable value, commonly referred to as GRV.

GRV is a term commonly used by quantity surveyors, valuers, financiers and developers. It refers to the estimated end value of the completed project if it were sold on the open market.

We use GRV for full end-to-end project management because, at the point we are usually engaged, the project may still be at concept stage.

For example, a client may have purchased a site and be considering whether to develop it into two townhouses, three townhouses, apartments, or another form of development. At that early stage, there may not yet be a final design, a completed scope, or a builder’s price.

What the project usually does have, or what we help the client develop, is a feasibility. That feasibility will almost always include a GRV figure.

At that point, GRV is often the most practical benchmark available. It gives both parties a way to set a fee before the full design, documentation, tendering and construction process has been completed.

The fee is then amortised across the expected project duration.

For example, if a duplex project has an estimated GRV of $3.6 million, then a 4% project management fee would be:

$3.6 million × 4% = $144,000 + GST

If the project is expected to run for two years from concept, design, procurement, construction and handover, that fee would typically be spread across the project duration:

$144,000 ÷ 24 months = $6,000 per month + GST

This gives the client a predictable monthly project management cost rather than one large upfront fee.

Once the project is more advanced and a build contract value is known, some services may be priced against the construction value instead.

Why construction-management-only is priced against the build contract value

Where we are engaged for the construction management phase only, the fee is typically calculated at 5% + GST of the build contract value.

This is different from full end-to-end project management.

By the time a project reaches the construction management phase, the construction contract value is usually known or can be reasonably quantified. The builder has been selected, the scope has been priced, and there is a clearer view of the expected construction duration.

For many residential and small development projects, a 12-month construction period is a reasonable benchmark. Larger or more complex projects may run for longer.

The fee is spread across the expected construction period as a monthly project management fee.

For example, if the build contract value is $1.8 million, then a 5% construction management fee would be:

$1.8 million × 5% = $90,000 + GST

If the project is expected to run for 12 months, that equates to:

$90,000 ÷ 12 months = $7,500 per month + GST

At BSP’s standard hourly rate of $220/hour + GST, that monthly fee allows for approximately:

34 hours per month.

That time is used to manage the construction-stage process, liaise with the builder and consultants, track programme and progress, review claims and variations, assist with contract administration, monitor risk, and keep the client informed.

The construction phase is generally more active and more time-sensitive than the earlier planning and design phases.

Once the project is on site, decisions often need to be made quickly. The builder may need clarification on drawings, selections, site conditions, engineering details, variations, programme impacts or consultant responses.

If those matters are not dealt with promptly, the project can slow down, costs can increase, and responsibility for delay can become unclear.

For that reason, construction management requires ongoing availability and active involvement.

A simple monthly workload example

To make the monthly fee easier to understand, consider a construction-stage support role on a project where the builder can claim each month.

A typical month may involve:

• one site visit and follow-up report: 3 hours
• processing one progress claim: 2 hours
• dealing with one variation or time claim: 2 hours
• design team or site-related queries: 16 hours
• other administration tasks: 4 hours

That totals 27 hours per month.

At $220/hour + GST, that equates to:

27 hours × $220 = $5,940 + GST per month

Of course, some months may be quieter. Other months may be more intense, particularly when design changes, builder queries, variation claims, progress claim issues, defects, delays or coordination problems need to be resolved.

The fee needs to allow for responsiveness as well as hours. It is not just the number of hours across the month that matters. It is also the ability to respond at the right time, protect the client’s position, and keep the project moving.

GST treatment

All BSP fees are quoted plus GST unless stated otherwise.

GST treatment can differ depending on whether the client is developing for profit or building for personal use. For-profit development clients may be able to claim GST credits depending on their structure and registration status. Owner-occupier clients usually treat GST as a real cost.

Clients should confirm their own GST position with their accountant or tax adviser.

What could poor project management cost you?

The cost of project management should not only be compared against the fee itself. It should also be compared against the cost of delay, variations, poor documentation, weak tendering, disputes and the client’s own time.

What could a one-month project delay cost?

Time delays on any construction project are the number one cost risk outside of unidentified poor ground conditions and poor documentation. This example of a delayed knockdown rebuild illustrates the significant financial impact.

Consider this example for a Knockdown rebuild.

• existing home loan: $400,000 (effectively what's going against the land)
• construction loan facility: up to $1.2 million
• assumed interest rate: 6% per annum
• temporary rent: $800 per week
• council rates: $500 per quarter
• site public liability insurance: $1,000 per year

A one-month delay in this example costs about $8,700. A three-month delay costs about $26,000. A six-month delay costs about $52,000.

The cost can be even higher late in the project, when most of the construction loan has been drawn. At full drawdown, the monthly holding cost in this example increases to approximately $11,700. That means a three-month delay near the end of construction could cost the homeowner approximately $35,000 in additional interest, rent, rates and insurance.

Every month matters.

Good planning, clear documentation and efficient project coordination are not just about convenience. They can help protect homeowners from thousands of dollars in avoidable holding costs.

What could variations cost?

Variations are another common source of cost pressure.

Anecdotally, quantity surveyors who assess progress claims for financial institutions regularly see projects where variations and cost increases run to 10%, 15% or even 20% of the contract value.

On a $1.5 million custom home, a 20% cost overrun represents $300,000 in variations.

Even where the client genuinely wanted the additional work, there is often a penalty in not documenting, pricing and negotiating that work properly before the contract is signed.

For example, if a $300,000 variation bill includes a 40% builder’s markup (due to the fact that the builder wants to make sure everything is absolutely covered, that there's no further cost risk, and that it may have caused a time hold-up or sequencing issue that's costing more money), the underlying work is approximately $214,000. Had the same work been priced before contract signing with a 20% markup, it may have cost approximately $257,000 — a difference of around $43,000!

The exact numbers will vary from project to project, but the principle is simple: the cheapest time to clarify, document and negotiate scope is before the contract is signed.

What about opportunity cost?

There is also the cost of the client’s own time.

If you are a business owner, developer or high-income professional, your time and attention have value. If you are spending large amounts of time trying to manage design issues, builder questions, contract claims, programme delays or variations, that time is being taken away from your own work.

For some clients, the opportunity cost of trying to manage the process themselves can be significant.

Is project management worth the cost?

That depends on the project and the client’s risk profile.

For a small, simple project with strong documentation, a good builder and a confident client, full project management may not be necessary. Targeted advice, a document review or a contract review may be enough.

For a larger project, a development project, a complex renovation, a knockdown rebuild, or any project where the client is unsure about scope, budget, builder selection or contract risk, independent project management can provide significant value.

The value is not only in managing the builder once construction starts.

It is in helping the client make better decisions before the expensive commitments are made.

Good project management can help reduce the risk of:

• unclear scope
• weak tender documents
• poor builder selection
• unrealistic budgets
• missing exclusions
• avoidable variations
• programme delays
• poor communication
• unmanaged contract risk
• disputes caused by unclear documents
• overpayment due to front-loaded progress schedules
• selecting a builder that may be at financial risk 

The earlier these issues are addressed, the cheaper they usually are to fix.

Which service should you start with?

If you are not sure what level of support your project needs, the best starting point is usually an initial review.

We can look at where your project is at, what documents you have, what risks are visible, and whether you need full project management, targeted advice, a contract review, tendering support or simply a clearer path forward. From there, we can recommend the level of support that fits the project.

That may be a one-off review. It may be tendering and builder selection. It may be contract review. It may be construction-stage support. Or it may be full end-to-end project management.

The right answer depends on the project.

The important thing is to understand the risk before you commit.

If you are planning a building project and want independent advice before you sign, tender, appoint a builder or commit further money, book an Initial Project Review with Build Success Partners.

We will help you understand what you have, what may be missing, and where the key cost, time and contract risks may sit.
