Building Engineering

The Engineering team of ANA, is not a separate business. They are an integral part of our design decisions and the sustainable performance of our buildings.We follow a process of integration of our building services, at the concept itself. Services are not to be “fitted” into the design… rather, services “serve” the building performance and the building accepts them gracefully and seamlessly.

Philosophy

MEP system is the lifeline of the building which defines the occupant’s comfort. Better the MEP design, more sustainable is the building. As every project is unique, So is the MEP design. Careful & thoughtful design with correct implementation results in good building structures in terms of comfort and building life cycle cost. One of our major drive of MEP design is that “Services Are Designed for Buildings” So, we design the MEP services to integrate with the building architecture design by :
• Understanding Architectural Concept
• Participating in the building design process from beginning
• MEP System Planning without compromising usable space by:
• Engineered Solution to meet building requirement
• Minimizing space requirement
• Utilizing negative areas

Why Work with Us?

The client comes with a vision to an architect which is to be developed in reality. Every client is distinct, but we have designed our process in such a way to make the journey during project life cycle interactive, smooth & transparent for every stake holder. Our team inputs flow into architecture from the Concept Design Stage. These result in:

  • Coordinated & Informed Design Decisions
  • Reduced Clashes & Crossings
  • Reduced Repetitive Iterations
  • Optimized Scheduling & Tasks
  • Accurate Budget Estimates
  • Communicative & Comprehensive

MEP in BIM

Our standard practice is to develop drawing in BIM so that MEP services will be properly coordinated with architecture, structure and interior. So the achievable heights will be clear and the adjustment in height can be done before the construction is started – This is almost impossible in CAD. Advantages of BIM over CAD :

• Good quality drawings with level of services at all locations and well coordinated.
• Coordinated model where building services can be clearly visualized and site team will have more understanding.
• Major hassle related to coordination at site will be eliminated.
• Reworking will be minimized – installation time will reduce
• Accurate quantities – so the cost variation will be minimal.
• The cost will be saved during construction which will offset the extra fee for producing drawings in Revit.
• An accurate as-build model and drawings can be obtained which will be helpful for doing any future changes.
