2. Traditional and Emerging Contractor Selection Methods

2.1 Traditional Selection Methods

The traditional approach to contractor selection typically involves a competitive bidding process, where contractors submit proposals based on a predetermined scope of work and specifications. The following are some of the most common traditional methods:

• Lowest Bid: This is the simplest and most widely used method, where the contract is awarded to the contractor who submits the lowest price. While seemingly straightforward, this approach can often lead to cost-cutting measures that compromise quality, safety, and long-term performance. Moreover, it may discourage innovation and foster an adversarial relationship between the client and the contractor [1].
• Open Tendering: This method allows any qualified contractor to submit a bid, promoting competition and potentially uncovering lower prices. However, it can also be time-consuming and resource-intensive, as the client must evaluate a large number of proposals. This is unsuitable if the field of appropriate contractors is very small.
• Selective Tendering: This involves pre-qualifying a shortlist of contractors based on predetermined criteria, such as experience, financial stability, and technical expertise. This approach reduces the administrative burden and ensures that only capable contractors are considered. It requires the appropriate level of due diligence in pre-qualifying the tender list.
• Negotiated Tendering: In this method, the client directly negotiates with a single contractor, often based on a long-standing relationship or specialized expertise. This approach allows for greater flexibility and collaboration but may lack the competitive pressures of a traditional bidding process.

2.2 Emerging Trends in Contractor Selection

The construction industry is constantly evolving, and new approaches to contractor selection are emerging to address the limitations of traditional methods. Some of the key trends include:

• Best Value Selection: This method emphasizes the overall value offered by a contractor, considering factors beyond price, such as technical competence, past performance, project management capabilities, and innovation. Best value selection requires a more comprehensive evaluation process but can lead to better project outcomes in the long run [2].
