The RIBA Plan of work is a standard method of operation for the construction of buildings, and is widely accepted as an operational model throughout the building industry. This is design by the architecture. The RIBA Plan is represents a logical sequence of events that should ensure that sound and timely decisions are made. Consequently, the plan suggests that all the decisions set out or implied, have to be taken, or reviewed. It is anticipated that the model will only need slight adjustments depending upon the size and complexity of the project. The project progresses from inception to feedback, i.e. from stages A to M in a linear fashion requiring the completion of one state before proceeding to the next.

Stage L: Completion Stage M: Feedback
Stage A- Appraisal
At this stage, the client will still be determining what business objectives are to be achieved from a design project, and what resources are to be made available.
State B: Development Brief
It is development of initial statement of requirements into the Developed Brief by or on behalf of the client confirming key requirements and constraints. It should be identification of procurement method, procedures, organizational structure and range of consultants and others to be engaged for the project.
State C: Outline Proposals
To determine general approach to layout, design and construction in order to obtain authoritative approval of the client on the outline proposals and accompanying report.
State D: Scheme Design
This state is to complete the brief and decide on particular proposals, including planning arrangement appearance, constructional method, outline specification, and cost, and to obtain all approvals.
State E: Final Proposals
To obtain final decision on every matter related to design, specification, construction and cost.
State F: Production information
The purpose of state F is to develop the State E information into the working drawings, specifications and schedules required to prepare the works tender information and related contract documentation. This state information will provide the basis of the contractual agreement with a main contractor and all subcontractors involved, and should include all the information they will each require to manufacture, deliver, install and hand over the finished works to the client.
Stage G- Tender documentation (Bills of Quantity)
This stage is to prepare and complete all information and arrangements for obtaining tender. Where applicable pass final information to planning Supervisor for pre-tender Health and Safety Plan.
Stage H- Tender Action
This state should be contribute to appraisal and report on tenders negotiations.
State J: Project Planning
To enable the contractor to programme the work in accordance with contract conditions; brief site inspectorate; and make arrangements to commence work on site
State K: Operations on Site
To follow plans through to practical completion of the building. To make visits to works in connection with the Architect’s design and further information reasonable required for construction.
State L: Completion
Identify defects and make final inspections, to hand over the building to the client for occupation, remedy any defects, settle the final account, and complete all work in accordance with the contract.
State M: Feedback
To analyses the management, construction and performance the project.
Based on the project which we chosen, the procurement system of the project is traditional procurement system. The RIBA plan of work is depending on the procurement system of the project. Therefore the state A to F is under the consultant such as architectural consultant, Quantity Surveying Consultant and so on. On the other hand, the state G to M is under the contractor. Those tasks to be done and people who directly involve in RIBA stage of the project are show on table below.

Commonly used terminology
RIBA Stage G
Bills of Quantities
To prepare and complete all information and arrangements for obtaining tender.
The AIMA contractor prepare of bills of quantities and tender documents for the TARC Admin Block
Architects, engineers and ,contractor (if appointed)
Site operation
RIBA Stage H
Tender Action
Prepare and complete all information and arrangements for obtaining tender. Identify potential contractors and specialists for the construction of the project.
Tenders obtained and appraised with recommendations made to the client body (TARC) or Steering group to allow an appointment to be made. It is important that the contractors’ (AIMA) understanding of, and commitment to, the project vision and its sustainability is tested at this stage. This can be achieved by the inclusion of this as a key selection criterion early in the procurement process.
-Hold pre-tender briefing for potential contractor (AIMA contractor) to ensure they have a good project understanding.
-Obtain and appraise tenders
-Appoint AIMA contractor
Architects, QS, engineers, client
Site operation
State J Project Planning
To enable the AIMA contractor to programme the work in accordance with contract conditions; brief site inspectorate; and make arrangement to commence work on site.
-Take action in accordance with the RIBA Plan of Work
- Appoint the AIMA contractor
-Handover the TARC site to the AIMA contractor to prepare prior to construction.
-the construction monitored by the design team and the design team appointed the site transfer to the AIMA contractor to get ready for commence work.
Contractor, sub-contractors
Site operation
State K Operations on Site
AIMA contractor to follow plans through to practical completion of the building
-Take action in accordance with the RIBA plan of Work
In this phase, review the information provided by AIMA contractor:
-Ordered site inspections of work to ensure it meets specification under the contract.
Architects, engineers, contractor, client
Site operation
State L Completion
AIMA to hand over the building to the client (TARC) for occupation, remedy, any defects, settle the final account, and complete all work in accordance with the contract
-Final inspection are made to ensure specifications have been met.
Architects, engineers, contractor, sub-contractors, QS, client.
Site operation
State M
Feedback
To analyse the management, construction and performance of the project.
-Analyse the job records to the TARC ADMIN BLOCK building
-Conduct studies of the TARC ADMIN BLOCK in use. These are particularly important to focus on energy in use against the design specification.
Architects, engineers, QS, contractor, client.
