The structural condition and functionality of bridges are a significant part of the transportation network. Every project needs to be technically and aesthetically correct, durable, economical, and the most sustainable solution for a given location.
Engineering design for a transportation project is done prior to the commencement of the construction phase and involves the planning and design of the entire project. Upon acceptance of the project, together with the client, a decision is made as to the scope and details of the project with the adoption of a zero-based management approach towards the entire design. The zero-based management approach ensures that the design is formulated from scratch to produce designs that are best suited to the client’s requirements.
During the pre-design phase, the assigned design team will work closely with the client to identify the details of the project which includes the identification of the purpose and location of the site. The design team will also analyze the viability of the project by performing market surveys, preliminary financial modelling, financial feasibility study and risk assessment and management.
The team will then carry out survey on the project site to collect data. This includes the study of the site’s topography, geotechnical and traffic study. Utilities mapping and infrastructure conditions surveys will be carried out. This will allow for the preparation of the term of reference.
After collecting data on the project site, the data will be analyzed to see if the project is viable. Once the technical study has been done on the project site, the financial feasibility of the project is studied and assessed.
If the project is found to be feasible, the design team will then move on to produce the master plan for the project. The design team will work closely with the client to conceptualize the project. During this process, the design team will take into account the purpose of the building as well as the requirement and needs of the client. The development order will also be prepared and submitted.
Next, the design team will perform an environmental impact assessment. Any impacts to the environment caused by the project will be assessed based on the work required to be done during the construction phase of the project. This will include noise pollution, air pollution, water pollution and others. Any foreseeable environmental pollution will be noted and steps taken to minimize the impact of the pollution.
Once contractors / consultants are appointed, meetings will be held with all parties to come up with the preliminary and detailed design of the project structure. This will include civil and structural design. After all the design reports have been compiled, the design team will prepare the project’s total cost estimation and perform value engineering to minimize project cost and maximize efficiency impact of the pollution.
