MBM Quantity Surveyors provide expert cost and contract management advice throughout an asset’s design and construction.

The pillars for this service includes:

MBM works with our clients in the initial stages of a project to undertake feasibility analysis and to advise on the project’s scope and definition. We can help optimise the design and ensure a realistic budget and program is prepared that reflects an experienced assessment of the project’s risks.

As a project’s design is developed, MBM prepares detailed cost plans, advises on the cost implication of design choices and undertakes value management to provide confidence in the project’s cost, design, construction and program outcomes.

MBM provides detailed Bills of Quantities for tendering and construction administration purposes. This allows for a comprehensive evaluation of tenders and provides a solid foundation for variation assessments.

MBM provides advice on the optimal procurement strategy, the selection of the best contractors and provides an independent evaluation of the tenders received. We assist in post-tender activities and support our clients to complete the project documentation to ensure the contract clearly reflects the project’s design, price and risk allocation.

MBM applies established cost monitoring and reporting procedures to review progress claims and completed works to recommend payment. We also monitor and cost any claims or client changes, provide cost to complete reports and negotiate any variations.

MBM applies an established risk management framework to safeguard the financier, developer and contractor by providing a detailed assessment during construction of the cost to complete, progress payments, variations and claims.
