Construction Industry Growth drives Global Economy

Global construction to grow by 67% from $7.2 trillion today to $12 trillion in 2020. Growth in China, India and the US will generate 54% of the $4 8 trillion India and the US will generate 54% of the $4.8 trillion increase in global construction output.A total of $97 7 trillion will be spent on construction A total of $97.7 trillion will be spent on construction globally during the next decade and by 2020 construction will account for 13.2% of world GDP.By 2020 emerging markets will account for 55% of global construction, up from 46% today. Construction will make up 16.5% of GDP in emerging markets by 2020, up from 14.7% in 2010.

Limitation of 2D Drawing (1/2)Limitation of 2D Drawing (1/2)

The reader must interpret 2D Drawings and recreate design intend b their knowledge and experience.These drawings can run into hundreds of separate documents, which make it very difficult to gain an overview of operations resulting in inconsistencies (Stebbins, 2007). CAD documents exclude information required for evaluating a design and monitoring construction activities (Oskouie et al., 2010). .

Limitation of 2D Drawing (2/2)Limitation of 2D Drawing (2/2)

Bids and contract documents, bill of materials (BOM), time frame specifications, costs, labelling as well as installing and maintaining guides are also not included.According to Knight (2008), the growing complexities of design models threaten to make complexities of design models threaten to make CAD drawings insufficient and redundant.

Key Drivers of Construction Productivity

Shifting construction activity to the factory affords better quality control, optimized production, lower cost labor and greater safety Field work shifts to coordination safety. Field work shifts to coordination, assembly, and unique conditions.

Improving productivity in construction : prefabrication/modularization is seeing a renaissance as technologies, such as BIM, have enabled better integration of have enabled better integration of components. Out of over 800 architecture, engineering and contracting (AEC) professionals surveyed:• 66% report that project schedules are

decreased - 35% by four weeks or more• 77% report that construction site waste

is decreased - 44% by 5% or more

B ildi I f ti M d li (BIM) hi h h b d fi d Building Information Modeling (BIM) which has been defined as “a digital representation or visualisation of physical and functional characteristics of a facility. In addition BIM serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward” (Eastman and Tiecholz, 2008). y p ( , )From this definition it is evident that BIM is a multipurpose tool facilitating design and development, data management and planning functions.and planning functions.The drivers for BIM are the exigencies of a fast expanding, increasingly complex construction industry, the need for more

Maturity Level of BIMMaturity Level of BIM

A maturity model was developed by the UK Department of Business Innovations and Skills (BIS). BIS defined the levels from 0 through 3. A majority of the market is still working with Level 1 processes, and the best in class are experiencing significant benefits in Level 2.

Values of BIM on DesignValues of BIM on Design

BIM i t i t 2D d 3D d i BIM is a great improvement over 2D and 3D drawings since it enables designers to view the building from all angles (Bentley, 2009). This enables identification of g ( y, )any errors at an early stage which can then be corrected avoiding costly rework.O f h f i li i f BIM i i i f One of the functionalities of BIM is incorporation of parametric design elements. Changes, additions or editions in any one parameter results in simultaneous editions in any one parameter results in simultaneous reconfiguration of all other elements involved in the design including sectional and elevation dimensions, raw material requirements cost of production and material requirements, cost of production and construction schedules and timelines (Emery, 2008)

BIM allows visualization of form with some resemblance to realities (Manning and Messner, 2008). This allows evaluation of both aesthetic and functional features. Thus even non – technical stakeholders can easily understand these models.BIM reduces safety barriers which in turn reduce BIM reduces safety barriers which in turn reduce insurance costs, legal fees and professional liabilities.liabilities.

4D BIM = 3D + Schedule (Time)The construction of the 4D models enables the various participants

(from architects, designers, contractors to owners) of a construction project, to visualize the entire duration of a series of events and display the progress of construction activities through the life time of the project. This BIM-centric approach towards p j ppproject management technique has a very high potential to improve the project management and delivery of construction project, of any size or complexity.project, of any size or complexity.

5D BIM = 3D + schedule (time) + cost

which refers to the intelligent linking of individual 3D CAD components or assemblies with schedule (time) constraint and cost-related information. Th f h 5D i i d d f h ddi i f f h The use of the term 5D is intended to refer to the addition of fourth dimension: time and fifth dimension: cost to the 3D model, i.e. 5D is 3D + schedule (time) + cost.

The construction of the 5D models enables the various participants ( from architects, designers, contractors to owners) of any construction project, to visualize the progress of construction activities and its related costs

Mover time. This BIM-centric project management technique has a potential to vastly improves the project management and delivery of construction project of any size and complexity.

BIM i t it f h i d i f ti BIM is a one stop repository for such varied information as supplier data, manufacturer information, costing, dimensional data and component specifications. p pConsolidation of data allows the project managers to provide clients with value added services. These include information on lighting heat power usage furniture information on lighting, heat, power usage, furniture and post occupancy requirements (Howard, 2008).Liston and Fischer (2010) believe that data attached to Liston and Fischer (2010) believe that data attached to individual components increases accuracy of pricing and bidding. Construction schedules can be optimized in the face of constant changes in availability and the face of constant changes in availability and delivery of raw materials and design changes.
