An information engineering approach to modelling building design

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

“…These models characterize geometry, properties, links, and attributes of the real objects [3]. It is assumed that a building consists of elements and parts different by their functions, properties, and manufacture technology [4]. A part may involve a simple structural component or a complex structure.…”

“…The constant mutual collaboration between the project's participants is the main obligation to ensure the effective management of construction project [3], [4], [17], [18] and it can be fulfilled by using 5D (five dimensional) modeling concept [8], [11], [19].…”

“…It is evident, that traditional procedures of the project development with limited use of the IT solutions [1], [2], [3], [4] leads to waste of time for documentation checking, drawing and redrawing, long duration of variation orders resolution during both design and construction stages [8]. The opportunity to have wide analysis and synthesis of alternatives is very limited there.…”

“…A growing diversity between disciplines, participants, tasks, tools and events while project management in design and construction stages [3], the rising pressure of costing competition and tighter production deadlines, together with consistently increasing quality requirements and necessity of technological enhancements, have been the driving force of information modeling and numerical simulation in building industry. The range of applications covers virtually every phase of the specific construction product development process [4], [5], [6], [7]: planning, design, estimating, scheduling, fabrication, construction, maintenance and facility management. Theoretical background and practical innovative applications of building information modeling and construction process simulation technique [6], [8], [9], [10] ensuring Virtual Project Development (VPD) concept [11] are observed in the article.…”

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

“…In this part of article five tables are presented with description of uncertainty sources [5,[10][11][12][13][14] and possible consequences. Sources and consequences are combined in five groups to clarify the type of uncertainty source: − ununified communication [5,12] and undefined "Project language" (see Table 1); − low qualification and professional training [15] of employees (see Table 2); − unestimated work amounts [16] in project's estimate and unacceptable planning of works [17,18] (see Table 3); − the lack of management tools [19][20][21][22] and ineffective-irrational organization of works on site [23,24] (see Table 4); − unclear responsibility limits [23] and no strict contractual obligations [14] (see Table 5). c) the lack of contractor experience (no experience in similar construction project, lack of professional knowledge, the deficiency of adequate project management) can lead to delay of time for project implementation, grow the expenses.…”
