What is the most suitable procurement method for each stage of the proposed development?

The procurement methods for a particular construction project is determined by certain factors such as speed, the quality expected, financing, risk, budget and specific project constraints. One of the causes of poor project performance is the use of inappropriate procurement methods and the use of appropriate procurement method is considered to result in the success of the project.

a) Design and Build

This particular procurement process will be important in the construction of low rise buildings residential buildings in Marrickville of approximately 60 and in this particular procurement method, the contractor will develop the design himself and after the design, the reviving of the design is done by the client and the contractor is requested to perform certain adjustments as per the aspects. Then the cost of construction and execution of the project is agreed upon. This process will be advantageous to the client since the client will not have to appoint the design consultant for the project. This particular method is also preferred in high rise buildings. The use of this method eradicates errors resulting from miscommunication since the project embraces collaboration which is the root of innovation and customization.

This method replaced the traditional method and in this process, the contractor, designer and the owner are working together as one team to meet the client or owner expectations.  The members of the team are focusing on solving the problems and not blame games. The method allows the owner of the building only to manage a single contractor who in returns manages all the subcontractors and designer. Some of the five phases the design-build process entails include;

1. Selection of the team. The owner is expected to choose a design-build team and this normally entails the design-architecture team.
2. Pre-construction. This is an important part of the construction process and this where some of the important factors are learnt such as the budget, goals and challenges, and the overall vision of the project.  In this stage, the project team is expected to work together to access current electrical systems and what to be done before construction work.
3. Architectural design.  After defining the project parameters, including location, budget and timeline are when the architectural design starts taking place.  The design-build team will look for areas for cost savings and optimized productivity.
4. The construction begins after everything has been assessed by the design-build team
5. Post-construction. An overview of the project deliverables is provided by the design team upon the completion of the project.

This particular procurement method will be of great advantage to the low rise buildings since the cost of the project will be established very early on in the process and this eliminates the risks of going over budget later during construction (Vilasini, 2011).  The use of the design-build method is becoming popular in most parts of the world since it delivers high-quality projects thus people prefer it in the construction of high-quality commercial construction such as manufacturing facilities, sports venues, municipal facilities and office buildings.  Some of the advantages associated with the design-build procurement method include the following;

• The schedule is compressed thus saving time.
• The contractor and design fees are kept to a minimum.
• The facility can be occupied by owners earlier(D, 2014).
• Early cost, design and materials input from the contractor.
• The changes in orders are greatly reduced or minimized.

b. Management Contracting

In medium-rise residential development, management contracting appropriate in development of medium rise residential buildings consisting of 144 units in Marrickville and it is considered an approach whereby the client participate in the appointment of  a management contractor. The client is expected to engage with the contractor to carry out an active role in the project at an early stage (Rahmani, 2017). The method is considered effective when pricing, time, flexibility and transparency are considered more important.

This method will help the client to reduce the risk associated with construction. The project will be divided into packages such that every package will have a contractor and this appointment is done at the design stage. The contractor is expected to participate in design development if the contractor is appointment in the design stages.  The contract agreement is anticipated to include both the pre-contract doings and post contract doings (Chew, 2011). Some of the tasks and services provided by management contractor at the pre-contract stage if appointed at the contract stage include;

• Participating as well as advising on matters dealing with design and possible enhancements.
• Recommending appointments of consultants.
• Inspecting and participating in viability studies.
• Supporting the approvals.
• Advising on the materials and production process.

Task and services provided by the management contract at the post-contract stage include;

• Upholding the site development and supervising the process of construction.
• Managing the suppliers and subcontractors.
• Settling out of the project.
• Organization of site examination and authorizing.
• Arrangement of welfare facilities and site accommodations.

Management contractor is expected to be experienced and the general design is the obligation of the client specialists while the packages of the work are defined by the management contractor (Foward, 2014).  Some of the benefits that will result from management contracting include;

• It is helpful for a complex project where there is slight design information is obtainable at the beginning of the project.
• Fixing of management and preliminaries fee permitting for a degree of certainty on price.
• The design team can control the quality(Vilasini, 2011).
• There is great scope for client changes.

This particular procurement method will be important in this particular project since it is considered a complex project since the project will be distributed into numerous sets. The subcontractors will be available during the construction of medium storey building and they will all be supervised by management contractors (Bebatunde, 2012). The owner is expected to converse with the management contractors and the client risks transferred to management contractors. This method is appropriate for complex projects such as for these medium rise residential buildings that will entail several subcontractors as shown below;
