While, [7] has identified 5 types of uncertainty as follow;
· Technical risk – scope change, technology selection, implementation technology selection, equipment risk, material risk and engineering/design change
To respond as government spoke, we proposed to develop the model of uncertainty to manage and give a very useful guidance to manager and engineer on their project development.
This uncertainty model should constructive with decision-making support by communicating the uncertainty using science engineering/project management interface.
The factors were generated through conversations, discussions and observations along with the project contractors and construction engineer.

Introduction The AEC-industry (Architecture-Engineering-Construction) is currently experiencing major changes.
Thus, they often are used to model complex settings and to act as communication gateway to software engineering.
Templates were generated via reverse-engineering from common building constructions.
The Reverse-Engineering results in a string constituent of the layer vocabulary and a grammar.

The resultant parameters of engineering interest and the boundary layer flow field parameters and have been presented using tables and graphically plots.
To address problems that need for a pressure barrier, several civil engineering solutions are created employing curved shaped geometry.
In many engineering areas, the importance of simulating unstable flow phenomena is rising.
Scientists and engineers can greatly improve the dependability and price of several fluid dynamics devices by comprehending unsteady flow and utilizing it in unique design approaches.
Engineering tasks requiring high operating temperatures place a greater emphasis on nonlinear thermal radiation.
