Technology and Innovation
“We are digitalizing construction driven by our vision of Building a Legacy of Construction Excellence“
We are able to link our BIM softwares to our fabrication machineries.
Our BIM capability for Structural Works enables us to draw the model up to the detail of rebars then export the rebar details and import BIM file to our rebar fabrication machineries.
This BIM initiative enables the company to fully automate the process from rebar drawing to rebar fabrication.
Digital Construction
“Digital Transformation improves Planning, Collaboration, and Capability for Automation”
We are digitalizing construction and we have slowly but consistently implemented Building Information Modeling in our construction processes for the past 10 years.
The shift towards 3D Digital Drawings has enabled our company to enhance our planning and collaboration capabilities. We are now capable of creating a single model consolidating the Structural, Architectural and MEPF aspects of a project.
With this, we are able to analyze projects better thereby reducing the implementation errors we experience. On the early stages of the project, we are able to visualize any conflicts and clashes in plan and talk about possible solutions together with our project stakeholders. As a result, we are able to engage our project stakeholders better and create faster action plans.
