For each project construction process MEP systems plays vital role and each project execution process involved three stages as follows .
Pre – Construction – In this process includes the feasibility study , designing , planning and cover up to the project BID/Tender Stage . In this stage basic involvement of Engineering firms or consultants .
Fig: MEP Project construction process Construction - This phase includes the co-ordination and production of shop drawing for installation of each accessories of MEP systems . In this stage basic involvement of GC , Sub- contractors .
Post – Construction- This phase includes the turnover of projects ( TOP ) of documents and drawings and involvement of facility management ( FM ).
MEP system consists of basically three systems Mechanical, Plumbing and Electrical including the Fire Protection system. In building, MEP engineering systems plays the major role parallel with the architect, structure from conceptual planning, detail designing stage to execution stage. All individual systems have its own sub system as follows.
MEP system contract/design drawings in strict compliance with contract specifications, technical submittals and the relevant codes which we use internationally.
Mechanical Codes - ASHRAE, ASME, ASTM, SMACNA , AS1668.2 – 2012, AS 4254.2-2012As per the international standard and guidelines ASHRAE, we do thermal load calculation through manually and through Autodesk Revit software which we use to provide for our US client.
As per the ASHRAE standard, our engineering team calculate the duct size a per constant velocity method. Our team having the capability to evaluate the flow as per the project requirement. We also provide the proposed duct size as per the standard velocity method for any missing duct size of contract drawing.
As per IPC fixture chart and inline with friction chart, we do the drainage fixture calculation, drainage pipe size and water supply pipe sizing.
We do electrical cable size and voltage drop calculation as per the schematic inline with NEC .
Virtual Construction of project in BIM enables Independent Review of the contract drawing in-line with requirement and technical specification we do internal value engineering with the following steps.
We produce permit Drawing/ Contract Drawing & design Models with the help of advance tools like Autodesk Revit in 3D and AutoCAD 2D process. 3D model creation process includes the following steps
We use to get the markup from PE engineers /Consultants of mechanical, plumbing system on the architect layout. Based on the markups, our 3D team use to produce 3D permit drawing set. MEP Contract drawing /document set consist of following for each system .
Our team has been trained for production of mechanical, plumbing and electrical system contract drawing.
The main purpose of the constructability review is to review all construction processes from start to finish during the pre-construction or at early design phase. This Constructability assessment helps to identify and solve different types of problems before the actual construction begins and helps to minimize errors, delays and overhead.Virtual Construction of project in BIM enables Independent Review of the Construction Plans and Specifications. This identifies discrepancies in drawings and all constructability issues at preconstruction stage. During the constructability review, our BIM team generates a series of RFI’s to identify following type of constructability and operational issues:
