Construction Defects

A vast number of studies about construction defects have been published in different countries, confirming that construction defects are a global issue. This problem often adversely affects the budgets, timing, and quality of construction projects. The lack of understanding about which construction tasks are prone to defects make implementation more uncertain and increases the chances of defects. This study seeks to identify and understand the behavior and pattern of task actions that are more prone to defects through the anatomy process of a specific task. The first objective in this study was to identify, track, and record construction defects during the execution of a number of actions within a specified task. The second objective was quantifying which actions are more prone to construction defects and determining the reasons why. Fifteen case studies were conducted on residential buildings, which included 45 items focusing on the column sub-task. Initial results suggest that some actions within specific sub-tasks are more susceptible to defects. This research aims to improve the understanding of construction defects and solutions, enhance cost controls, reduce time overruns, and improve execution quality.

Line Of Balance

The finish work on high-rise residential buildings is performed simultaneously with mechanical and electrical construction work, which results in frequent work interference and delay. This significantly hinders efficient schedule management. Critical Path Method (CPM) is inefficient when applied to high-rise residential building projects in which work is repeatedly carried out for each floor. Line-of-Balance (LOB) is widely used for its effectiveness in managing repetitive work. LOB was developed into TACT and eTACT (enhanced-TACT) to combine heterogeneous works con­tinuously. In particular, the eTACT schedule management method has an advantage in that it is capable of systemati­cally connecting detailed construction, mechanical and electrical construction projects using a work planning template. This study evaluates the time reduction effect of the eTACT method for a high-rise residential building. A comparative analysis of data on 102 cases of non-applied projects and 44 cases of projects using the eTACT method over a period of 10 years is presented to verify its effectiveness. The result shows that finish work time was reduced by 25% or about 53 days on average.

The Relationship

Because of their bespoke nature, construction projects are susceptible to variations irrespective of type, size and complexity. The effects of these variations are significant and may include cost and time overrun, productivity, and waste issues at the minimum. Although variations have been widely researched, investigations into the relationship between the significant causes of variations and their effects have not. This study also considers control measures that could minimize variations in residential building projects, where significant variations are happening in the Sri Lankan construction industry. A questionnaire survey was administered to study participants with the objective of identifying significant causes and effects of variations on residential building projects. The participants were professionals across industry groups such as clients, consultants, and contractors who deal with variations on Sri Lankan construction projects. The study found that change in designs or project scope by owners or design consultants were due to owners’ financial problems, errors and omissions in design, conflicts between contract documents, inadequate working drawing details, lack of coordination by consultants, differing site conditions for contractors, unforeseen problems and weather conditions. Cost and time overruns are subsequent effects of those variations. The study suggests that variations could be minimized by adopting control measures that are appropriate for both the design and construction stage.

Abstract Conceptual cost estimation is important for construction projects. Either underestimation or overestimation of building raising cost may lead to failure of a project. In the paper authors present application of a multicriteria comparative analysis (MCA) in order to select factors influencing residential building raising cost. The aim of the analysis is to indicate key factors useful in conceptual cost estimation in the early design stage. Key factors are being investigated on basis of the elementary information about the function, form and structure of the building, and primary assumptions of technological and organizational solutions applied in construction process. The mentioned factors are considered as variables of the model which aim is to make possible conceptual cost estimation fast and with satisfying accuracy. The whole analysis included three steps: preliminary research, choice of a set of potential variables and reduction of this set to select the final set of variables. Multicriteria comparative analysis is applied in problem solution. Performed analysis allowed to select group of factors, defined well enough at the conceptual stage of the design process, to be used as a describing variables of the model.

Abstract Risk is involved in every construction project. Residential building construction projects comprise a variety of risks and are more likely to be affected due to their difficulty and many operations and threats. The study aims to identify the various risk elements and their effect on construction projects of residential buildings using a fuzzy approach with the help of MATLAB software. This study includes 60 risk factors recognised through an expert opinion and literature review. These factors are categorised into 7 major groups, i.e., construction, project manager, architect/consultant, contractor, owner, resources, and external environment-specific risk factors. A questionnaire was prepared and sent using emails based on the identified risk factors to be filled out by construction industry professionals in India and by conducting in-person interviews. Based on the risk severities obtained from the fuzzy model, the top 10 risk factors have been considered. As a result, for identified top severe risk factors, a significant risk response strategy was implemented.

Most commonly, residents are always arguing about the quality of their high rise residential property. A growing number of high rise residential buildings in Malaysia with differing light well were designed by the structural design and planning since 15 years ago. This light well is defined as an intermediate space area between indoor and outdoor of the high-rise residential building. The questionnaire survey of three high rise residential buildings that have different sizes of the light well and building designed were conducted to make clear the occupants' evaluation about the real quality conditions of the buildings. As a result, the quality of light well is clearly satisfied and well managed by the property manager in their high rise residential buildings.
