Current situation Out of the box / the large project Norms from the Netherlands that should be

adopted Work Methodology BouwData PB®

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

Actual building costUp to 30%

Aspects of an effective building project

BUILDING

PROCESS

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®

Available norms

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?

expertise of the other building partners Transparency and sincerity Teamwork

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.

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
