Computer-Aided Modelling, Evaluation and Management of Construction Projects According to PLM Concept

Application of Building Information Modelling and Construction Process Simulation Ensuring Virtual Project Development Concept in 5D Environment

“…Such expression of 3D model in time within all its life and costs is the project's 5D conception [23]. A constant cycle is being executed within the stages of this 5D concept model (Fig.…”

“…By applying information and model-based technology solutions to allow the automatic generation of drawings and reports, design analysis [2], cost estimating [7], schedule simulation [16], facilities management , and more -ultimately enabling the building team to focus on the information and their decisions [19], rather than the documentation tools and process [23]. The result is a better way for building teams to work -with time saved, improved quality, and better buildings because of the informed decisions made along the way.…”

“…Project documentation requires less time wasted on grunt work [23]. Professionals can spend less time documenting decisions and more time making them [13].…”

“…With coordinated documents and well-captured design intent, the enhanced design process makes for a far more informed design environment [23].…”

Methodology of Risk and Uncertainty Management in Construction’s Technological and Economical Problems

“…It is advisable to take all possible design decisions in the beginning of evaluation phase before obtaining of construction permit, because later the effectiveness of change decrease and the price of changes increase. As we see from Figure 1 (Migilinskas, Ustinovichius, 2006) [28] design decisions made in project initiation are economically rational and have bigger influence than the decisions made later. To solve the project uncertainties and design ambiguities it is recommended to use an expert services, it can ensure the professional opinion with evaluation of alternative solutions [6,7,9] at the very beginning of project implementation [27].…”
