The objective of this Guide is to assist MEP (Mechanical, Electrical and Plumbing) BIM users to develop BIM model(s) for new or existing project. It shows the possible use-cases of BIM at various design stages of the project.
This is a general document that covers a few typical buildings and is not an extensive document that covers all scenarios that might arise based on specific projects. Users are allowed to edit/change accordingly to suit their needs.
This document is not based on any specific software. This document does not cover the explanation and steps on how to use the software. For the steps and explanations of specific software, please refer to the software help or user manual.
Based on the project requirement, type and time line choose the BIM use and implement in the project.
Model Stages for MEP Design
1. Preparation & Conceptual
a. Understand Project Brief (Client’s Requirements) Design
b. Define BIM Execution Plan
c. Set up BIM Project Template, coordinate system, grids, level height,
2. Schematic Design
a. Preliminary Model based on architectural Massing structural and site models (identify ceiling height, opening, load bearing structures, services connections on site)
- Determine Design Criteria, Key Service Connections, Services Routes and Plant Room.
- Preliminary MEP Model Layout
- Preliminary MEP Services calculation report
- Schematic Drawings
- Alternate Design
3. Detailed Design
a. Understand & validate Architectural and Structural Models Define Zones, Spaces, Services Routes and Plant Room
- MEP Services Calculation Reports (load & sizing)
- MEP Services Model Layout and Detailed BOQ by Trade
b. Clash Detection & Resolution Report among different MEP trades (ACMV, plumbing, sanitary, fire protection and electrical)
c. Clash Detection & Resolution Report w.r.t. Architectural & Structural models
d. Regulatory Submissions
e. Render Documents
a. Design Validation Report
b. RFI Resolution
c. Shop & Working Drawings
d. Single Services Drawings (SSD) & Combined Services Drawings (CSD)
e. Detailed schedule of materials & quantities
5. As Built a. As constructed Model & drawings
b. Operation & Maintenance Manual (OMM)
c. Commission reports
6. Facility Management a. As built model
