1.1 Objectives of Cost Planning
Advantages of Cost Planning
• To find out cost
• To keep within budget
• Close gap between budget estimate and Contractor’s tender
• Efficient design process
• Value for money
• Helping the client decide how it wants to allocate the budget to the various parts of the project.

1.1 Objectives of Cost Planning
Cost planning is a management process that seeks to control design development in line with the client’s budget. It does this by helping the client decide how it wants to allocate the budget to the various parts of the project.

1.1 Objectives of Cost Planning
The objectives of cost planning are:
• To ensure the client obtains an economical and efficient design in accordance with the agreed brief and budget
• To make the design process more efficient, thus reducing the time needed to produce a successful design
• To ensure that everything within the client’s brief is included in the cost planning process

1.1 Objectives of Cost Planning
Cost planning occurs throughout the design development phase of a project. Where design and construction overlap, cost planning might run into the construction phase of a project. On design and build projects it is a tool that can be used by the contractor to control design development against the contract sum.

1.1 Objectives of Cost Planning
• For example, for a laboratory project, the building services elements might be a priority within the budget.
• Alternatively in a five star hotel it might be the internal finishes elements that are most important to the client.
• So, in addition to controlling the overall budget, it helps to develop the design in relation to the planned expenditure of the budget against the various functional element of the project.

1.1 Objectives of Cost Planning
Cost planning covers:
1. Establishing the budget
2. Cost modelling ahead of any design
3. Establishing a cost plan, i.e. distributing the budget over the functional elements of the project
4. Benchmarking
5. Obtaining sign-off by the client and the project team
6. Cost checking design development against the cost plan
7. Value engineering the design to meet the cost plan
8. Re-assessing the cost plan at key design stages
