Mining & construction

In a Design-Bid-build (DBB), Tacmin Construction will bid and if sucessfull act as the contractor responsible for construction delivery. This approach is popular because it’s simple, and owners often feel it can help maintain lower project costs than other methods. Here’s how it works:

Design: In the first phase, the owner contracts a design team that includes architects and engineers to help conceptualize the entire project. The owner and designer will determine a project’s structure and features, the scope of the project and the primary criteria that define a successful outcome.
Bid: The owner then puts the project up for contractor bids and chooses the optimal construction team. On public projects, the invitation to bid extends to any qualifying contractor registered to work on government projects. For private projects, the owner decides whether to swing the doors open for anyone to bid or limit bids to a few known contractors.
Build: The final phase involves finalising the commercial arrangement between the selected contractor and the owner. Once this is complete, the parties will proceed with bringing the physical project to life.

The Integrated Project Delivery (IPD) method is a collaborative and efficient approach to construction projects. It establishes multi-party agreements, ensuring that all stakeholders, including the client, design team, construction team, and trade partners, are contractually bound to complete the project. This method promotes better communication and a higher level of collaboration as everyone is working together from the start, reducing the chance of miscommunication or misunderstandings. Furthermore, IPD involves all stakeholders from the beginning, creating a more efficient project process and ensuring everyone is working towards the same goal. The risk and responsibility are equally spread among all stakeholders as everyone involved in the project is on a single contract that is predetermined before the design phase begins. This approach can be particularly beneficial in infrastructure and mining projects where collaboration and communication are key to success. However, it’s worth noting that there are other methods like Design-Bid-Build and Design-Build, and the choice between these methods depends on the specific needs and circumstances of each project.

Target Value Design (TVD) is a method of designing and constructing projects that focuses on achieving a specific cost target while still meeting the functional and aesthetic requirements of the project. This approach involves collaboration between the design team, the owner, and the contractor to identify cost-saving measures and optimize the design to meet the target budget. In TVD, the project’s target cost is set at the beginning of the design process. The design team then works within this budget to create a design that meets the project’s requirements. The contractor is involved in the design process to provide input on construction methods and materials that can help achieve the target cost. This approach is particularly beneficial in infrastructure and mining projects where cost control is crucial. It allows for a more efficient use of resources and can lead to significant cost savings. However, it requires a high level of collaboration and communication between all parties involved. It’s worth noting that there are other contract types used in construction such as lump sum (or fixed price), time and materials (T&M), unit price, guaranteed maximum price (GMP), and cost-plus. The choice between these contract types depends on the specific needs and circumstances of each project.

In a Design and Construct contract, the construction management team is responsible for both the design and construction of the project. This means that the contractor will be responsible for developing the project design and carrying out the physical construction. The principal usually engages design consultants to prepare a concept or preliminary design to help clarify the project requirements. Design and Construct contracts are undertaken by our EPC partner - TacminMadini Australia. They will use these preliminary designs as a base to develop and complete the design. Thereafter, they will progress the preliminary design to final ‘for construction’ design documentation. Work is then carried out in accordance with the final design documentation. Under this delivery process, our EPC partner assumes all risks in the design, including design defects, delays, constructability, regulatory compliance, and issues concerning the interface of design with construction. This also includes any cost overruns or schedule delays. The benefits of this approach include a more cohesive team and a higher level of accountability. The contractor is the single point of responsibility in the event of defects. The EPC contractor can identify site-related challenges early and factor this into the design, improving efficiency and reducing costs. The contractor has the opportunity to contribute their construction experience to the design, resulting in building innovation, cost and time efficiencies, and a more flexible design.
