Scaffold is without a doubt an excellent product which when applied to the correct set of circumstances provides a fast and cost effective solution. What we have done is to take a look at the circumstances where we see that scaffold does not provide a best fit access solution and design a better solution, the WEB Deck. If you are looking at a ground based access solution where you have no issue with access to the ground level, then scaffold fulfills its purpose. However, when you enter the work sites where you cannot use or obstruct the ground level then hanging scaffold is erected with a much higher time to install and therefore cost. This is one of the sets of circumstances that scaffold metaphorically falls down and where the WEB Deck provides a faster and therefore cheaper temporary work platform. In order to illustrate this point take a look at the tabl e below which outlines a bridge under deck are of 30m x 10m. The numbers are estimates and will vary from project to project, but they offer a good comparison of the products in this work area application:
