It is an innovative new approach to building design, construction and management which has been introduced by AUTODESK (2002). ? BIM have an impact on most areas of business management and operation. It changed the way industry professionals worldwide think about how technology can be applied to building design, construction and management. ? It will revolutionise methods of working and redefine the relationships between construction professionals. ? It will challenge current thinking on contracts and most importantly, it will support the integration of the design and construction teams. ? BIM supports the continuous and immediate availability of project design scope, schedule and cost information that is high quality, reliable, integrated and fully coordinated. BIM provide a visual aspect of the design, hence simplifying the work on the construction site. Thus, Building Information Modelling (BIM) may be considered as the current state of art in CAD developments. ? Advances in drawing technology which is Computer Aided Drawing (CAD) make the researchers and practitioners working hard to exploit CAD data in order to generate Bills of Quantities. ? Currently it is being implemented by a significant number of architectural and engineering practices, and has the potential to revolutionise the quantity surveying profession. An effective definition of BIM is provided by Schwegler, he process of creating an information database for a project in which lifecycle information is expressed in an interoperable manner to create, engineer, estimate, illustrate and construct a construction project. †¢ In this system, the design data will be kept in digital form which will make it easier to update-better coordination and it will be more valuable to the industry professionals. †¢ Apart from that, creating real-time, consistent relationship between digital design data with innovative parametric building modelling technology Can save significant amount of time, money and increase the project productivity and quality The Differences between CAD and BIM Building Information Modelling (BIM), how it may revolutionise the QS profession Due to the auto-measurement created by BIM we are able to inform the design as it develops with the knowledge of quantity and cost, not just measure and cost the design, which is often too late. Apart from that it will also facilitate the preparation of accurate estimates. |The process of taking the existing design information at design development stages and modelling it in 3D are used in terms of the | |identification and as an aid to eliminate clashes and co-ordination errors. |Once we developed the 3D modelling and process it to dynamically populate Bills of Quantities and specification from models. | |The BIM services became in demand by being able to compete on cost with traditional methods but able to respond faster and benefits of | |the core process of modelling to provide a visual record of what has been measured where. | Therefore the quantity surveyor does not have to do estimates and measurement for the project. Thus, the quantity surveyor does not have to do Bills of Quantities and specification for the project. Using BIM is like we use the best available technology to do things faster and better, and eliminate waste and repeated work. In order to avoid the inefficiencies we need to normalise data, enter information once and reuse it many times, turning data into an asset in which it could be as simple as entering the name and address of a supplier once at the inception stage of a project. When we enter the supplier’s information, automatically current price of the item will be inserted in the digital data information. The core process of 3D modelling for measurement produces model that can be divided for many other purposes at marginal cost. For instance ? clash detection, ? construction sequences ? printing physical models ? presentation and visualisation, ? speeding up the process of understanding information about the project ? communicating it to those who are not so adept at reading drawings Apart from that, the mode of communication between the construction professionals also changed due to introduction of BIM in the construction industry. This is because, the building product model is used as a tool to communicate with other professionals about costing where this situation will reduced the QS time spend in communicating with architects, engineers, contractors and client. By using this building product model, people will get a clearer view in what the QS explained about. Next, with the introduction of BIM, the progress of works in all stages will be reduced. This is due to the sophisticated software where any correction on the drawing will be automatically updated on the building model and there is no need for other profession to revise their works. If any disputes occur, they can just refer to building model to justify or make any amendments. Highlight and discuss the future strategic skills of QS due to the advent of BIM and such like At the end of twentieth century, many challenges had been faced by the profession. With the increased activities associated with the information technology in which removed some of the repetitive tasks related to their work make the profession to develop and utilise their skills more fully. For instance, from solely considering initial costs of construction emphasis which then shifted to identifying and adding value to the development processes. ? The quantity surveyor need to expand their skills, expertise and client based in order to survive. The 21st century quantity surveyor should be a resource primed to add value to the entire development process by the unique menu of skills and competencies. ? The knowledge driven services provide competencies that should encourage â€Å"service mix†. It is like retooling the traditional skills and require expansive of new streams of knowledge to face the challenges. Thus, a quantity surveyor firm should specialize in a selection of the se services which has been organized in cognate clusters. Therefore, they have to differentiate its services portfolio. 1. Financial advisory services | |Investment appraisal | |Financial analysis | |Life cycle costing | |Expenditure statements for taxation and account purposes | |Capital allowance management | 2. Management Advisory Services | |Feasibility studies | |Cost planning / management | |Property management | |Facility management | |Asset management | |Risk management | |Conditions survey | |Value management and analysis | |Replacement cost for insurance purposes | 3. Procurement Management | |Preliminary cost advice | |Estimating, measurement and quantification with the help of BIM | |Advising on contractual methods | |Advising on the contractor’s selection | |Preparing tender documents | |Obtaining or negotiating tender bids | |Valuing construction work | |Preparing and agreeing accounts with contractors | |Cost control and post contract management | |Project management and coordination | |Scheduling and planning | 4. Legal advisory services | |Expert testimony / litigation support | |Arbitration | |Dispute and conflict management (ADR) | |Advice on claims preparation and claim defense | |Contract auditting | The general orientation is that the QS profession has shifted from a mere technical function to a more managerial function within the context of the market place It is rather a deepening of expertise in the core traditional function while adding on other competencies as dictated by the market place. Apart from that, a quantity surveyor should develop inter-personal skills in order to survive in this competitive environment. The traditional professional service posture is sales oriented rather than marketing oriented. We should know that the era when clients consulted the consultants has long disappeared. Nowadays, the consultants are compelled by the market to ‘consult’ potential clients it is like ‘reverse consulting’. Therefore whilst ‘sales orientation’ focuses on ‘selling the professionals’ services to the customer/client, ‘marketing orientation’ develops new services to suit the client’s changing needs. |Selling |Marketing | |a |Emphasis on product |Emphasis on customer/clients wants | |b |Company first makes the product and figures out how |Company first determines what customer/clients wants and make | | |to sell it |product/services to satisfy those wants | |c |Planning is short-run oriented in terms of today’s |Planning is long-run oriented in terms of new products, tomorrows| | |products and markets |market and future growth | The quantity surveyor must now provide clients with strategic advice at a much higher level than previously actions. We must place ourselves higher up in the agenda by providing strategic advice at entire group of people, advising on how best to manage the entire cost and property portfolio. Quantity surveyor is a professional who is able to analyse construction into its cost significant elements and functions, able to translate and extract the key quantity and cost elements of drawings and specifications into contract documents that then enable the delivery of best value for money through an understanding of construction, economics and management’, as opine by Westcott and Burnside (2003). Apart from that, quantity surveyor should set good benchmarks for its current cost levels, set up a source of cost information which keeps pace with the growing industry needs and critically analysis project costs. The quantity surveyor should have communication skills in order to adapt with the fast changing of construction industry. We should be an effective communicator and to get our point across without misunderstanding and confusion. The content of our message should be clear enough for them to understand, concise, accurate, and well-planned communications. Apart from that, the quantity surveyor needs to enhance themselves in information technologies where it is also known as computer skills. It is because BIM only relies on those skills. They should master the basic computer skill as well as the complex computer skills in case they have problem with the software. In this era, those who do not know how to operate the computer device will be left far way behind the successful people. Thus, it is necessary for the quantity surveyor to master the computer skills and vast knowledge in information technologies.
