The Problems with the Closed-Book (Lump Sum) Model
A Closed Book Cost Model, also called a Lump Sum contract, sets a fixed price for the whole project. Although it may sound appealing, this approach can create several challenges for clients.
Unidentified Costs & Variations
Incomplete designs or changes during construction can lead to expensive variations that quickly increase the project budget.
Reduced Quality
To protect profit margins, some builders may select lower-quality materials, less skilled labour, or reduce costs during construction.
Absence of Transparency
Clients often cannot see the detailed breakdown of project costs. This can create confusion, mistrust, and frustration.
Less Visibility. Less Flexibility.
This lack of visibility and flexibility can make the Closed Book model less suitable for clients seeking fairness and peace of mind.
Why Is Our Cost Plus Model Better Than the Closed Book Model?
Our Cost Plus Model gives you greater control, transparency, and flexibility throughout your construction project.
The difference between Virk Construction Management and conventional builders is our Cost Plus Model, or cost plus construction contract. Our model is an open-book, collaborative engagement, unlike the rigid lump sum approach. This gives you greater control and transparency throughout the project.
This approach supports ethical and transparent project costing. Every project cost is recorded, so you can clearly see where your money is being spent and understand the financial position of your project.
Under a cost plus contract in NSW and Canberra, we competitively tender every trade package to the open market. This helps secure competitive pricing and better value without compromising on quality.
We also maintain strong supplier relationships and pass negotiated commercial discounts directly back to our clients wherever possible.
Lower Builder Fees
Our fee structure can reduce unnecessary builder costs.
Competitive Trade Pricing
Every trade package is competitively tendered to market.
Supplier Discounts
Negotiated commercial savings are passed back to clients.
Flexible Changes
Scope and design changes can be managed more flexibly.
Cost Plus vs Traditional Lump Sum
See how the two construction approaches differ across key project areas.
| Project Area | Virk Cost Plus Model | Traditional Lump Sum |
|---|---|---|
| Pricing | Actual project costs plus a fixed management fee. | A fixed contract price is established before construction. |
| Cost Transparency | Open-book pricing with project costs clearly recorded. | Limited visibility into underlying trade and supplier costs. |
| Trade Packages | Trade packages are competitively tendered to the open market. | Trade pricing is generally incorporated into the agreed contract price. |
| Supplier Discounts | Negotiated commercial discounts can be passed back to the client. | Discounts may remain within the builder's commercial pricing structure. |
| Variations | Changes can be accommodated more flexibly as the project progresses. | Variations can involve additional pricing and contract adjustments. |
| Client Control | You have greater visibility and control over project spending. | Cost control is primarily based around the agreed contract scope. |
| Project Flexibility | Easier to adapt designs, selections, and scope during construction. | Scope changes can require formal variation processes. |
| Financial Clarity | You can see where project funds are being allocated. | The final contract price provides less visibility into individual costs. |
