What is Progressive Design-Build?

The Design-Build has been in the AEC industry architecture. This concept aligns expectations upfront before executing the work of design and construction thus it significantly reduces the misaligned expectations for scope, cost, and schedule between the owner and design-builder. Therefore, they not only gain full advantage of the design-builder’s expertise but also work collaboratively to develop a design that meets the projects’ goals.

Interim Phase- Evolution of Design & Beginning of Construction

Building Information Model (BIM) represents various BIM dimensions. BIM not only represents the design in three dimensions but also enables the Design-Build team to measure the impact of any design changes. There are advantages of BIM model-based cost estimation, it can reduce errors, and save time and resources that can be utilized for operation and maintenance or for other projects.
Many benefits come with the adaption of Virtual Design and Construction.

1. It Makes Contractor Selection a More Organized Process.

BIM Model connects a database to the design. Every revision made to the database will automatically result in an updated design since the data integration and visualization is conducted almost in real-time. For projects where the quoted price is not the only differentiator, BIM can prove to be a comprehensive catalog for displaying capacities in designing and constructing projects, using the work a Design-build firm has taken in the past.

2. Easier Visualization Increases Probabilities of Conversion

Although the Owners have to specify the Phase I KPIs prior, consultants might still be hired to conduct a constructability study.the process for submitting the relevant files becomes easier. BIM can be of great help in giving project walkthroughs, cross-section analysis up to less than an inch, and MEP modeling.

3. The Owners Get Access to The Common Data Environment Aiding Expectation Management

BIM allows larger teams to come together and work in unison. This helps in clash detection at a very early stage. Once the construction begins, the shared model can be monitored for guidelines and updated if they make any changes in the design. This can help multiple teams associated with the project and the Owners to be easily aware of the intricate and actual progress being made.

4. Space for Running Scenario Analysis and Forecasting a Reliable Cost Structure

At any point in the project’s life cycle, the Owners might ask for a revised costing proposal. When Phase I is being undertaken, the Design-build firm is asked to provide a costing proposal. In a project being run without BIM, this becomes very challenging since the firm has to test the project from the entire AEC perspective.

BIM has different dimensions of development. 4D BIM is the 3D model with time data integrated into it. 5D BIM is the 3D model with the financial data integrated into it. With adequate adjustments to both the generations and some rudimentary conditional probabilities, the firm can give a very accurate and controllable costing proposal.

5. Easier Project Evaluation and The Possibility to Bring Sub-Contractors Early in The Process.

BIM is meant for collaboration. Hence, if the firm brings sub-contractors early in the project’s life cycle, it will help the project team iron out any potential constructability issues. Sub-contractors bring the domain expertise for the corresponding fragment of the project.

In short, BIM services are here to stay, helping in many parts of the process, achieving more and minimizing errors as much as possible. As the need to construct additional buildings with fewer resources and less skilled labor increases, we must discover new ways to meet demand more efficiently, more efficiently and faster.
