Procurement Selection 1.0 Introduction Macclesfield Cricket Club Ltd is going to rebuild, refurbish or relocate its clubhouse. The proposed budget for this project is £800,000. The client has allocated a construction period of 12months for the on-site works associated with the construction of a new clubhouse. A further period of 9 month is available for the pre-construction phase involving planning, building approvals, sub-contractor selection, design development, method planning and mobilisation. Handover of the completed building would be before February 2013. 2.0 The Eternal Triangle In a construction project, the three most important criteria for a client to take into consideration are cost, time and quality. It is at the client’s interest to achieve the highest quality, at the lowest cost, in the shortest time (The Aqua Group, 1999). These three criteria can be demonstrated in a triangle as the figure shown below. Cost Time Quality Figure 1.0 The eternal triangle. (The Aqua Group, 1999) The Aqua Group (1999) found that if these three factors are kept in balance, with appropriate quality being achieved, at an acceptable price, in a reasonable timescale, the triangle would appear equilateral. It is therefore essential to get the client’s priority right at the first place as the criteria is related to each other and criteria that are of lower priorities are possible to be managed well. 2.1 Radar Chart Below is a radar chart (Cox and Clamp, 2003) for Macclesfield Cricket Clubhouse which presents the three elements of cost, time and quality in terms of contract priorities and client priorities. (Priority = 0 lowest – 5 highest scale) Cost Cost (Total - 12) C2 C1 – Lowest possible capital expenditure. (4) C3 C2 – Certainty over contract price, no fluctuation. (5) 5 C1 4 C3 – Best Value for money overall. (3) 3 2 1 Time (Total – 5) 0 T1 Q3 T1 – Earliest possible start on site. (1) T2 – Certainty over contract duration. (4) T3 – Shortest possible contract period. (1) Quality (Total – 7) T2 Q2 Time Quality Q1 – Top quality, minimum maintenance. (2) Q2 – Sensitive design, control by employer. (3) Q3 – Detailed design not critical, leave to contractor.

Certainty over project duration is very important. 4.2 Cost Firm price is needed because the project must complete within the budget £800,000. The client might have limited funding and price must be firmed before operations start on site. 4.3 Flexibility Flexibility is needed when the client decided to make variations during the construction process. There may have variation for allow more sport facilities. 4.4 Complexity Club house is simple project but needed to achieve all client requirements. Off site construction method may be used for this simple project. Club house does not need to be high aesthetic designed and achieve sport activities requirement is more important. 4.5 Quality The clubhouse must provide all the facilities for sport and leisure purpose. Clubhouse must be designed base on standard sport activities requirement. 4.6 Certainly The project must complete before Feb 2013 and within the £800k budget. The client might have limited funding and require the reassurance of a fixed price with no risk of fluctuation. 4.7 Division of responsibility It is believed that client has experience involve in construction project. Thus, the division of responsibility is not an essential factor. Risk may transfer to contractor by using design and build procurement. 5.0 Recommendation In my opinion, the identification for selecting a proper procurement system is through the procurement system selection matrix which in this case, the design and build has found to be more suitable for this project. Procurement - Design and Build Pre-tender time largely depends on the amount of detail in the client’s requirements. Construction time reduced because design and building proceed in parallel. It is efficient single contractual arrangement integrating design and construction expertise within one accountable organisation. There is a guaranteed cost and completion date. This procurement is benefits in cost and time but at the expense of quality. Advantages – 1. Builder adopts a major portion of the project risk through the design development of the initial concept. 2. Builder can retain control of the design process and has the ability to ‘fast track’ in order to be more cost effective. 3. Single point of responsibility from the client’s perspective. Disadvantages – 1. Cost pressure on builder’s side can lead to short cut in the design, and designing only to meet the minimum performance requirements of the contract. 2. Promotes cheapest capital cost options which could have significant life cycle ramifications in terms o cost and durability for the client. Type of Contract – JCT form Design and build procurement method gained acceptance in the early 1980s with the introduction of a ‘with contractor’s design’ variant of the standard JCT form. Recently it has been endorsed by the public sector as a preferred procurement option, and most publishers of standard forms now produce documents which allow for a contractor’s design responsibility. The contractor may have responsibility for some or all of the design of the project. The contract wording must expressly refer to this, and the extent of the design obligation needs to be set out as clearly as possible.
