 The “battle” between building partners is no longer socially acceptable.  The younger generation is “no nonsense” and does no longer play cat and mouse.  New software such as groupware and BIM demand teamwork and transparency. Social factors

 The quality of the contract decreases. Program of demands of the client is less clear.  Risks in design and resaerch are passed on to the contractor.  Contracts become fixed.  More and more subdivisions of building contracts. Trends in contracts

 Search for mistakes in the file of specifications. A negative margin on “false” posts. Creating an alternative scenario.  Anticipate the indecisiveness of the client and uncertainties in the research.  IN BOTH CASES: Deductions with substantial profit margins. Scenarios in contracts

Payed by: 1.The client by way of deductions. 2.The subcontractor by way of poor contracts. 3.The contractor by way of loss-making activities. The Result Contract sum Actual building cost Up to 30%

Decision building project Demolition building  Cost-effective project  Knowledge locations & environment, accompanying legislation  Unique project  Creativity  Economical project  Know-how with regard to 1. design & realization of the building 2. management during the life cycle of the building  Within the presupposed execution time  Organization Aspects of an effective building project BUILDINGPROCESSBUILDINGPROCESS

 All the previous aspects:  handle within context  more defined as the building process makes progress  Most efficient organization:  project teams consisting of developers, designers, engineers, building supervisor and managers  excessive knowledge management Aspects of an effective building project (2)

1.Building Declaration. Test the design against one legal frame of reference. 2.Technical building specifications for the entire project. For each project there can only be one performance file of specifications that grows as the building process progresses and that only formulates the necessary preconditions for the execution. 3.Standard cost control method. Cost engineering as an independent discipline = IFRS for the building industry = BouwData PB ® Taking policy measures

 On elemtary level the SfB is recognizable: = an international classifying system (The Belgian version was published in 1990 by the State control of buildings)  NEN 2634 integrates the investment norm NEN 2631 (= NBN B06-003) and explores it more profoundly Why adopt NEN 2634?

 Develop the quality and cost data to a certain level in each phase of the building process  Acquire knowledge and understanding from existing detailed calculaltions in the benifit of the following building projects Goals of NEN 2634 ?

 = proven to be a thorough instrument because buiding partners from the Netherlands refuse to deviate from STABU when searching for technical solutions  The STABU-organization seeks alliance continuously with new techniques and execution methods. Last edition: 2007  The STABU-organization takes part in the world- wide debate about BIM and groupware Why adopt STABU?

Key notions  Professionalism  Each building partner knows his position in the building process  Each building partner acknowledges the expertise of the other building partners  Transparency and sincerity  Teamwork

Development BouwData PB ®  On C3A-net with the support of IWT (nr  Concept & basisc lists are free of charge  Monitored by 350 building professionals

System of agreements BouwData PB ®  Administration groupware  Phasing of the building process  Structure of the performance building specifications and conditions specific for a project  Structure of the technical building specifications and conditions specific for a project  Variety of costs  Quantities and units  User functions and space designations  Cost centres and accompanying ratios

Administration groupware  Structure of files in accordance with the norms: 1.Column A of chart 4 BB-SfB with regard to the main classification 2.NEN 2634 with regard to the classification of the building process 3.STABU with regard to the classification of technical solutions  Definition building partners and stakeholders.  Establishing accompanying rights.

Administration groupware (2)

Building phases  Phase 1 : Project definition = the determing budget and timing  Phase 2 : Structural design = rough layout including the main building structure and technical shafts  Phase 3 : Design  Phase 4 : Development  Phase 5 : Execution

Building phases (2) Calling in building partners  From the moment their knowledge is required  The same criteria for each building partner (team of development, design and execution):  Expertise  References  Price
