BREIFING STAGE

BENEFITS• Able to assess site planning or

analysis more easilyDuring the preparation stage, contractor could use BIM-based site planning to understand job site constraints and a visual aid to communicate with the client.

01

BREIFING STAGE

BENEFITS• Offer better visualisation to ease the production

of conceptual estimates and the function to automate the generation of quantities and measurements directly from a BIM model

02

BREIFING STAGE

BENEFITS• Using 3D model visualization tools to ensure

better communication between different stakeholders0

3

BREIFING STAGE

CONSTRAINTS• Limitation in calculationFor example, REVIT is one of the well-known BIM based software.Weaken deduction function. Weaken finishing handling capacity.

04

BREIFING STAGE

CONSTRAINTS• Not flexible with construction cost

variationBIM software estimates the total expected construction cost by providing the cost-to-complete of a project. However, BIM does not count price variations that might be occurred.Unforeseeable variations:

05

BREIFING STAGE

CONSTRAINTS• High cost of software, hardware and

trainingCurrent trends show that the cost of BIM software packages tends to be more expensive than CAD software packages available on the market.

06

DESIGN STAGE

BENEFITSLogistic Resource Efficiency at the Design Stage• The ability to create a detailed 3D model

BIM reduced the demand for paper drawings and their revisions. The use of BIM saw the estimated reduction of 9,000 paper drawings in the design phase.

07

DESIGN STAGE

BENEFITSLogistic Resource Efficiency at the Design Stage• Improved holistic communication

BIM has driven efficiencies across the whole design, contractor and supply-chain teams. Thus, BIM has saved 15,000 hours collective man hours throughout the design development progress.

08

DESIGN STAGE

BENEFITSLogistic Resource Efficiency at the Design Stage• Improved efficiency of design procedure

BIM streamlined the design process,improving not only collaboration but theearly management and integration of expertise on the project

09

DESIGN STAGE

CONSTRAINTS• Required experienced team membersA dedicated BIM team member must have the knowledge to manipulate the model and address any changes. With such a large model and an inexperienced team member, access to the design sometimes required two or three team members.

11

DESIGN STAGE

CONSTRAINTS• Transition from drafting to modeling When moving from a CAD-based drafting environment to a BIM-based modeling environment, a change in the workflow will surround what used to be simple drafting tasks such as copying markups or picking up redlines.

12

PRE-CONSTRUCTION STAGE

BENEFITS• Using 3D or 4D site coordination modelsThe planning through using BIM enhances site utilization, space coordination, and product information. A 4D model can either include a site logistics plan or tools such as SMARTBOARD.

13

PRE-CONSTRUCTION STAGE

BENEFITS• Better Assess in Constructability AnalysisBy using BIM models, the project team can perform detailed constructability analysis to plan sequence of operations at the jobsite.

14

PRE-CONSTRUCTION STAGE

BENEFITS• 5D Cost EstimatingFrom building information models, the contractors can perform fairly accurate quantity survey and prepare detailed estimates during the tender preparation stage.

15

PRE-CONSTRUCTION STAGE

CONSTRAINTS• Time ConsiderationBIM enhances the use of “design to build” and “build to design” concepts. The visualization, fabrication, coordination, and construction planning were carefully studied • Electronic Data Transfer – Data SharingContractual issue to address is who will control the entry of data into the model and be responsible for any inaccuracies.

16

CONSTRUCTION STAGE

BENEFITS• BIM in Prefabrication

Prefabrication reducesfield labor cost and time and increases accuracy in a good quality construction.

17

CONSTRUCTION STAGE

BENEFITSGPS Technology in the field1

8Bar Coding or Radio

Frequency Identification Tags

Machine Guided Technology

Laser Scanning

CONSTRUCTION STAGE

CONSTRAINTS• Time ConsumingThe use of BIM based scheduling is recommended for only detailed construction planning and monitoring for activities such as quality control and quality assurance programs as well as punchlists because it requires more effort to create and update activities.

• DisruptiveAlthough one of the advantages of using a BIM model is that changes can be made quickly, BIM can disrupt the general procurement and construction process when ordering items that require a long lead-time.

19

POST-CONSTRUCTION STAGE

BENEFITS• Easy access into Facility Management

OperationsFor example, the information that is extracted for a piece of equipment such as a VAV box are location, name, model number, product type, operation and maintenance manuals, commissioning information and performance data. This makes it very simple for a maintenance worker to access the required information vital to different systems in the building.

20

POST-CONSTRUCTION STAGE

BENEFITS• Record ModelThe model includes the integration of the as-builts from the subcontractors. Furthermore, each object property in the model can also include links to submittals, operations and maintenance, and warranty information. Centralized database can help the facilities department to find information easier.

21

POST-CONSTRUCTION STAGE

CONSTRAINTS• ChallengingThe interoperability of the record model with various applications could potentially be a challenge.

• Absence of cooperation amongst the project stakeholders for model utilization and modelling

The constractors and designers do not know or familiar about the documents and other information required for the phase of facility management.
