Systemic integrated method for assessing factors affecting construction timelines

Abstract

Abstract. To streamline construction planning, one needs to assess and perform trial modeling of organizational and process-related factors impacting the final planned performance indicators. A proper calendar plan, one that would take due account of said factors, has a substantial impact on the efficiency and, sometimes, even the feasibility of a construction project as a whole. Therefore, the purpose of this paper's research is to develop a method for determining optimum technical and economic parameters. A method should be considered legitimate which, given the labour intensity of the jobs assigned to a crew and the list of such jobs, makes it possible to determine the time said jobs will take to perform depending on the variation of the following factors: crew/unit numbers, job synchronization degree, job performance sequence, number of shifts and unit productivity. The authors have studied the algorithm and the method for the trial modeling of organizational and process-related factors when developing a calendar plan in order to identify qualitative time-specific and feasibility parameters. The paper reviews the example of how the optimum performance timelines for each crew can be determined.

Organizational and technological solutions during the production facade works

“…Despite the fact that the process of mastering advanced technologies for thermal protection of buildings began a long time ago, the problem of manufacturing defects when performing work on insulation and finishing of facades, as before, remains one of the most important problems of modern construction. Moreover, if at the initial stage of introducing thermal insulation systems for external enclosing structures into domestic construction practice, a mass marriage could be attributed to imperfect technologies or a lack of professionalism of installers, today the unsatisfactory quality of facades is a consequence of a series of mistakes made by participants in the architectural and construction process at various stages of project [9,10]. This is largely due to the developing and immature construction market, in which dozens of companies have appeared that supply systems for protective and decorative finishing of buildings, and contractors that provide installation services, among which there are many companies whose main principle of production and commercial activity is to obtain profits by any means, including by saving on high-quality building materials, non-compliance with the production technology, low level of organization of construction production.…”

Studying the methods for determining and maintaining sustainability of a construction firm

“…As a matter of priority, it is important to specify the firm's main resources (equipment), give them an expert assessment and, using the model (1), identify the construction firm's resource potential indicator [15,16,17] for subsequent evaluation of its sustainability.…”

Audit of design estimates and organizational and technological documentation in the process of construction expertise

“…The research part, in turn, consists of [8,9,10,11,14,15]: -Visual and instrumental examination; -Laboratory research; -Analysis of project, working and performing documentation; -Analysis of organizational and technological documentation; -Analysis of estimated calculations (cost expertise); -Geodetic surveys; -Carrying out verification constructive calculations. The final part of the expert's conclusion is the conclusions, where the answers to the questions put to them are briefly given.…”
