Why VISI

In the projects which are carried out by businesses in the Soil, Road and Water Construction sector, intensive communication takes place between the parties involved. VISI

With the DEMO methodology the various collaborating roles have been defined and agreements have been made about the format and meaning of messages exchanged between parties involved. These agreements have been dubbed VISI, which stands for the creation of conditions for the implementation of standardisation of ICT in construction.

The benefit of VISI is the in reased effciciency of collaboration, thanks to the clear communication process.

The construction industry is characterized by changing cooperational relations between the different parties involved. During the entire process - from the first idea until finally the use and operational management - there are constantly new cooperational relationships being formed. Some parties stay involved in the project over a longer period of time, while others come and go. Good communication between the parties involved is paramount for the efficiency in the project. The quick agreement on changes by all building partners, and the prompt availability of the last version of a drawing at the building sight, has great influence on the quality, the time span and the costs of a project. 

Project partners experience that poor communication is an important bottleneck in the building industry. In early 1998 a number of organizations from the building sector came up with the plan to formulate agreements about communication between partners in building projects. This plan formed the foundation for what is now known in the sector as 'VISI'. 

What does VISI stand for?

VISI stands for 'creating conditions for the establishment of standardization of ICT in the building industry' and its goals can be defined as follows:

1. The parties involved have generally applicable agreements about the content and design of communication available to them.
2. With these agreements the parties are able to enter into cooperational relationships and set up communication structures faster and more flexibly.
3. The parties are able to handle the outside world in an more assessable manner and to increase the quality of the product.
4. With these agreements the tools in the area of information and communication technology (ICT) are better utilized.

What it simply comes down to is that VISI aims to make unambiguous agreements about the (digital) communication at the points of contact or interfaces between parties in building projects. These agreements must lead to the ability for the parties to find each other at will.

The Solution

The agreements which have been developed are related to communication which is needed to securely register the formal transactions between the partners in a building project. For example for the settlement of alterations or the submittal and approval of a budget.

The agreements that VISI has developed are grouped according to areas of application. A group of agreements is referred to as a VISI-framework. The first area of application for which a VISI-framework is made available is in the communication between the principal and those employed by the principal in an UAV-agreement. This framework is simply referred to as VISI-framework UAV.

What are these agreements about? The most important component is formed by a collection of messages in the form of forms. These messages are ready to use in practise. Every message has specific data elements, independent of the goal of use. Thus in the VISI framework UAV we find a message for the submittal of a budget; in this message we see data elements to indicate which number of the budget it refers to, and which amounts are applicable.

 
Aside from the messages there are a number of other matters which are settled in a framework; for example which messages belong together to settle a certain procedure is fixed. Furthermore the order of messages is dictated. Think about the submittal of a budget. This begins with the message 'budget' which is submitted by the employed party. Subsequently the principal can choose whether to answer with a message 'rejection budget' or 'provisional approval budget', etc. The collection of messages for the settlement of such a procedure and their order is called a Transaction in VISI.

Finally, in communication it is important that it is clear from who messages come and to whom they go. In a VISI-framework this is fixed through roles. In a transaction there are always 2 roles involved. If we again take the example of 'submitting a budget', then the two roles involved are the principal and those employed by the principal. 

The result

Five large government principals in the building industry decided to introduce VISI in phases. The five principals are Rijkswaterstaat, Dienst Vastgoed Defensie, Rijksgebouwdienst, ProRail and Gemeentewerken Rotterdam. They signed for this in December 2006 in an implementation decision. The implementation took place in phases. In 2007 the principals carried out a number of their gww-projects, which were placed in the market based on the UAV89, with VISI. This way the individual organizations and their building partners could get used to this form of communication. From 2008 onwards the use of VISI in all UAV89 projects has been made compulsory. For the B&U 2008 was the introductory year and the obligation to use VISI counts from 2009 onward. It was expected that from mid 2007 the contract model UAVgc would be introduced. The principals had to make a decision about this independently.
