MEP Design

Applications :

Coordinated Design: Leveraging the process of BIM, VDEC develops MEP design models by iterating on the specifications and sizing of different utility systems. Through 3D modelling, we make sure that the routing for the services are done in a clash free manner, after which all the drawings and quantity related deliverables are generated.

Better Understanding:

The 3D BIM model adds a lot of value to the project in the form of better visualization, clash detection, constructability analysis and more. Apart from being well coordinated, the model gives an added dimension and more clarity to the contractor and other stakeholders during execution.
International Standards: VDEC has knowledge of design standards for all the major design codes followed and we can effectively carry out design projects and generate deliverables for projects around the globe. Our procedures are commensurate with the increasing use of Building Information Modelling workflows across the world.

MEP Engineering and Design is a complex field which needs knowledge of design standards and also practical workability of the solutions. VDEC provides high quality MEP Design deliverables for complex projects and adds the benefits of the BIM led workflow which adds more value than any other conventional CAD workflow.
The level of details and understanding which is provided through the BIM model is unparalleled and gives the client an opportunity to execute all the MEP services and their installation in a smooth and informed manner.
We are also experts in custom component creations for the service related components like chillers, pumps, DBs and therefore can do space analysis and constructability analysis at the design phase itself.
