Objective of BIM Project Execution Plan

To successfully implement Building Information Modelling (BIM) on a project, the project team has to develop a

MBIM Project Execution Plan. The BIM Project Execution Plan defines uses for BIM on the building construction project from design, engineering, construction to facility management, along with a collaboration process for executing BIM on the project.The goal of the BIM Project Execution Plan is to manage and control the quality of the BIM deliverables

Quality for BIM ProjectQuality for BIM Project

Q lit ti t ’ ( d) i t f l Quality means meeting customers’ (agreed) requirements, formal and informal, at lowest cost, first time every time. To success, we should understand the current and future customer

d h ld d d needs, should meet customer requirements and strive to exceed customer expectations. We should create and maintain an internal environment in which people can become fully involved in achieving the project’s objectives. A desired result is achieved more efficiently when activities and related resources are managed as a process. So identifying, understanding and managing interrelated processes as a system are required. Further continual improvement of the overall performance should be a permanent objective of the organization.

Model StructureModel Structure

The success of a BIM enabled project delivery process is highly dependent upon the level at The success of a BIM enabled project delivery process is highly dependent upon the level at which the entire project team can communicate and work collaboratively for the duration of the project.For buildings with a large footprint or multiple floors, the project team may split the model into

l ( fl ) ith th di t dseveral zones (or floors) with the corresponding tradesAll trades will be modeled at the correct elevationAll elements of the building must be represented in only one file and should be modeled by their specific trade. (For example, the architectural model provided for 3D Coordination p ( p , pshould not include any of the structural elements contained in the structural model. Lights should be modeled by the electrical engineer, not the architect)All 3D model files must strip extraneous 2D and/or 3D elements from the model before submission for clash detectionsubmission for clash detectionThe architectural ceilings should contain information of lights, diffuser, speaker, CCTV, etc. as required by design. (For example, lights are to be centered on a grid with proper spacing)All models should include separate 3D representations of required clearances and/or access

i f i li h l h d bl Th requirements for equipment access, light clearances, overhead cable tray access, etc. These clearance/access models should be in a separate layer(s)/level(s) per each trade and labeled as such

Level of DevelopmentLevel of Development

LOD 100 The model equivalent of conceptual design the model would consist of overall LOD 100 – The model equivalent of conceptual design, the model would consist of overall building massing and the downstream users are authorized to perform whole building types of analysis (volume, building orientation, cost per square foot, etc) LOD 200 – Model that includes basic elements including windows walls and doors. This level of

d li i f i li ti d b i l i d i i il t th h ti d i modeling is for visualization and basic energy analysis and is similar to the schematic design or design development. It consists of generalized systems or assemblies with approximate quantities, size, shape, location, and orientation. LOD 300 – Model elements are suitable for construction and are the equivalent of traditional

t ti d t d h d i Thi d l l l ld b it bl f l i d construction documents and shop drawings. This model level would be suitable for analysis and simulation of detailed elements and systems. LOD 400 – Model level of development considered suitable for fabrication and assembly. This model will include all as-constructed details for the CLIENT’s use to manage the facility. This is h i l f b il d i i h di i l i the equivalent of as-built drawings in the traditional construction process.

LOD 500 – The final level of detail represents the project as it has been constructed including property assets itemized with key parameters required by the CLIENT added to the model. All as-built record drawings and documentation at the time of turnover must be provided in the CAD f l f El l d d h d l b d l d b h h 2D d 3D CAD native file format. Elements included in the model must be detailed in both the 2D and 3D documentation for CLIENT use. Elements must be clearly marked or tagged and visual in both the 2D and 3D documentation.

The project team should document the information exchanges created as part of the planning process when creating the BIM Plan. The level of development (LOD) for each model p ( )element is based on the model content criteria. The LOD will assist in determining the level of LOD will assist in determining the level of involvement for each project stakeholder from project conception through project turnover. project conception through project turnover.

COBie DefinitionCOBie Definition

Construction Operations Building Information Exchange (COBie) is a data format for the publication of a subset of building model information focused on delivering building information not geometric modeling. It is closely associated with building information modeling (BIM) approaches to design, construction and management of built assets.g

Quality ManagementQuality Management

I d t d l lit i j t h t l In order to assure model quality in every project phase, control procedures need to be set in place. Each of the models created during project progression and d l d b l d d d l development needs to be pre-planned considering model content, level of detail, format and responsible party for updates, quality and distribution of the model to all the parties involved in the

di ti ff t coordination efforts. Each of the parties contributing to the BIM model should have a responsible person or Model Manager to handle the model. Model Managers, as part of the core BIM team, are in charge of participating in design reviews and coordination sessions along with taking care of all the issues that might arise with keeping the model updated, accurate and comprehensive.


Quality Control ChecksQuality Control ChecksCHECKS DEFINITION

Vi l h k Ensure there are no unintended model components and theVisual check Ensure there are no unintended model components and the design intent has been followed

Interference check

Detect problems in the model where two building components are clashing including soft and hardcheck components are clashing including soft and hard

Section check Cut section to compare with the 2D drawing and take measurement for critical areas

Standard check Ensure that the BIM and AEC Standard have been followed (fonts, dimensions, line styles, levels/layers, color, etc)

Model integrity check

Describe the QC validation process used to ensure that the Project Facility Data set has no undefined, incorrectly defined or duplicated elements and the reporting process on non-compliant elements and corrective action plans

Random check Checking any missing, un-reasonable and clash matter thro’ the model
