All About BIM Management

BIM Manager is responsible for delivering a business' technology strategy; promoting the benefits of digital technology. The BIM Manager must ensure that the team and the project run smoothly and that the project models and information are delivered on time as agreed by the parties involved.

BIM Manager within a Design Team:

Responsible for defining BIM Standards
Developing BIM Content
Setting up and deploying BIM Templates
3D Model Planning
Modeling Multiple Disciplines
Model Management
Design Delivery
Being the owner of the drawing sets - liaison with company IT leaders and virtual reality team.

BIM Manager within a Construction Team:

Responsible for Creating the BIM Execution Plan
Setting up of 3D Model Delivery and Asset Operations Plans
Coordination Between Disciplines
Clash Detection
BIM Coaching
Mentoring and Hands-on Training with On-Site Team Members
Working alongside the Estimating and Scheduling Teams
Staying Ahead with the Latest Tech Trends, Laser Scanning, Augmented Reality, Mixed Reality and even owning the latest drone and best 360 camera

BIM Different Roles:

BIM Manager - wide implementation of BIM processes and related technology
BIM Coordinator/Leader - team or project BIM leader
BIM Modeler - responsible for the integrity and accuracy of modeling
BIM Technician - responsible for doing stuff with the model, produce clash-detection reports, parse clashes in Navisworks, export CAD, etc.
BIM Support - responsible for troubleshooting, help desk and content creation

Some of these roles may somehow overlap or switch, depending on companies setup for responsibilities and limitations of tasks. Having a deep knowledge of construction and wide knowledge of BIM at the same time is rare commodity.

BIM LEVELS

BIM LEVEL 0
- Low collaboration.
- 2D Drawings.
- 2D CAD and PDF with only basic information.
- No collaboration with CAD drawings.
BIM LEVEL 1
- Partial collaboration.
- 2D and 3D models.
- Most commonly used at the moment.
- Partial collaboration through CDE (Common Data Environment).
- Usually being managed by the contractor. 2D and 3D information is available at this stage.
BIM LEVEL 2
- Full collaboration.
- 4D and 5D dimensions are included.
- Multi-trade BIM 3D models.
- All parties have their own 3D CAD models.
- Common file formats (IFC or COBie) can be accessed by parties.
- Seamless project collaboration and a unified BIM model.
- At this stage, multiple 3D models for different project teams on a digital platform.
BIM LEVEL 3
- Full integration.
- Single work-shared BIM model.
- All parties can add and edit information.
- At this level, all agents work on a single, shared project model located in a centralized, cloud-based repository.
- This is know as Open BIM or iBIM. Single work-shared 3D model for different project teams.
BIM LEVEL 4
- Planning and scheduling.
- Single work-shared BIM model.
BIM LEVEL 5
- Cost estimation
- Planning and scheduling.
- Single work-shared BIM model.
BIM LEVEL 6
- Sustainability and energy efficiency.
- Cost estimation
- Planning and scheduling
- Single work-shared BIM model.

BIM LEVEL OF DEVELOPMENT (LOD)

Pre-Construction Stage:
- LOD100 - Conceptual Drawing
  - 2D presentation of a basic concept
- LOD200 - Schematic Design
  - Partially design idea of the approximate size and location of building elements.
- LOD300 - Precise 3D Modeling
  - Detailed 3D digital representation of the building.
Construction Stage:
- LOD350 - Construction Document
  - Construction ready model.
  - Defines connections between building materials through efficiently running clash detection programs, resolving them, and providing accurate BIM coordination services.
- LOD400 - Fabrication Model
  - Fabrication and Assembly.
  - Information on supplementary building components for fabrication and assembly.
  - Accurate number, size, location and materials are defined for assembling and installing building facilities.
Hand-Over Stage:
- LOD500 - As-built Drawings
  - As-built final model.
  - Contains the actual size, number, location, material, construction and installation process, installation date, comments from contractors, etc.
  - Can be used for facilities management after the construction project hand-over.
  - Asset tagging is an added advantage of using the COBie parameter.

BIM DEFINITION OF TERMS AND ACRONYMS

AEC - Architecture, Engineering and Construction
BIM - Building Information Modelling
BEP - BIM Execution Plan
LOD - Level of Detail
EIR - Employers Information Requirements
CDE - Common Data Environment
IFC - International Foundation Class. IFC file format are BIM files.
COBie - Construction Operations Building Information Exchange. Based on the NBS, COBie is a non-propriety data format for the publication of a subset of building information models (BIM) focused on delivering asset data as distinct from geometric information.
NBS - National Building Specification. UK-based business providing construction specification.
MIDP - A Master Information Delivery Plan (MIDP). This defines on who is responsible for preparing the information and what protocols and protocols and procedures will be used to develop the information.
TIDP - Task Information Delivery Plans (TIDP). This shows who is responsible for each information deliverable.

BIM EXECUTION PLAN (BEP)

BEP will detail the project deliverables stipulated by the contract and the information exchange requirements in a BIM protocol (CIC BIM Protocol).
At tender stage, before a contract is agreed, a prospective supplier will develop a BEP, demonstrating their proposed approach and capability, capacity and competence to meet the EIR in general terms.
Once the contract has been awarded, the winning supplier is required to submit BEP to confirm the supply chain's capabilities.
MIDP - A Master Information Delivery Plan (MIDP) must also be submitted to set out when project information is prepared across a project. This defines on who is responsble for preparing the information and what protocols and protocols and procedures will be used to develop the information.
TIDP - Task Information Delivery Plans (TIDP) - shows who is responsible for each information deliverable.
There should be one main BIM Execution Plan.
Pre-Contact BIM Execution Plan Stage
- BEP at this stage is designed to address the EIR.
- EIR sets out the information required by an employer at points in a project where key decisions need to be made.
- EIR supplements the project brief.
- EIR defines the information about the built asset that the employer wishes to procure.
- Aim is to ensure that the design is developed in line with the employer's needs and that the employer has the ability to operate to the development up to completion, effectively and efficiently.
- Pre-Contract BEP should address everything requested in the EIR.
- Pre-Contract BEP must:
  - set out the Project Implementation Plan (PIP)
  - project goals for collaboration and information modelling and key project milestones
  - oversee where the plan, goals and info fit with the broader project program
  - set out how the project's information model will be assembled and delivered.
Post Contract BIM Execution Plan Stage
- The post contract document will now require far more effort from the now appointed Principal Designer.
- The BEP should list the agree targets for the timely delivery, exchange, reuse and final handover to clients.
- All the agreed elements as outlined in the EIR will also be listed.
- BEP should include:
  - agreed roles and responsibilities (and relevant authorities and approval process)
  - strategy for key deliverables and what existing information will be used
  - guide to the key project milestones and where these fit as part of the wider program.
  - logistics of collaborative process (including modelling) should be laid out with clarity of responsibilities.
  - a revised PIP and TIDP showing responsibility for delivery of each supplier's information
  - a Master Information Delivery Plan (MIDP) which sets out when project information is to be prepared by whom and using what protocols and procedures.

IMPORTANCE OF HAVING BIM MANAGER FOR A PROJECT
