Design and Build #
Design and Build
Design and build is a procurement method in construction where a single contract… #
In this approach, the client enters into a single contract with the design and build contractor, who assumes the risk for delivering the project within the agreed budget and schedule.
The design and build method offers several advantages, including faster project… #
However, it can also pose challenges such as limited client involvement in the design process and potential conflicts of interest between the designer and builder.
Design and build contracts are commonly used for fast #
track projects, where time constraints are critical, and the client prefers a single point of responsibility for the project delivery.

Public #
Private Partnership (PPP)
A public #
private partnership (PPP) is a contractual arrangement between a public sector authority and a private sector entity for the financing, design, construction, operation, or maintenance of a public infrastructure project. PPPs are used to leverage private sector expertise, resources, and innovation to deliver public services more efficiently and cost-effectively.
PPPs in construction typically involve a long #
term partnership between the public and private sectors, where the risks and rewards of the project are shared based on agreed-upon terms. PPPs can take various forms, such as build-operate-transfer (BOT), build-own-operate-transfer (BOOT), and design-build-finance-operate (DBFO).
PPP projects are often used for large #
scale infrastructure developments such as highways, airports, and public buildings, where the private sector's involvement can bring additional value and expertise to the project. PPPs require careful planning, risk management, and stakeholder engagement to ensure successful project delivery and long-term sustainability.
Open Tendering #

Selective tendering allows the client to engage with a select group of contracto… #
It reduces the number of bids received, streamlining the evaluation process and enabling a more focused assessment of the contractor's capabilities.
Selective tendering is often used for complex or high #
value projects where specialized skills or technical expertise are required. It provides the client with greater control over the selection process, allowing them to work with contractors who have a proven track record of delivering similar projects.
