S-Curve analysis in the construction interpreted as managing project with knowledge and traceable in the context of sustainable construction while displays the cumulative costs, labour hours or other quantities plotted against time. In the contract administration, delays in completing a construction project led to the breach of contract but, in contracts itself allow the construction period to be extended where there are delays that are not the contractor's fault. Under those circumstances, a presentation of a case-study regarding the analysis of S-Curve of a life project drew comparative interpretation of project performance towards project delivery schedule has been conducted in private initiative project. This study aims to investigate and examine the factors that cause delays in construction projects from the perspective of S-curve representations. The paper aims to provide in depth light about the existing causes of project delay and describe the key sources of financing problem and identify the consequences of contraventions of contract. Two distinct parts divided which are refers to the methods used to assess the perceptions of clients, consultants, and contractors on the relative importance of causes of delay in a project and referred to the procurement and documentation to analyse the delay. As a result, an Extension of Time (EOT) granted and identically changed the progress towards extension time where better planning demanded for improvement and restoration progress kept on track. This paper presented a practical and comparative S-Curve within extension of time to ensure delivery of project on schedule. In the long run, the identified causes are combined into 16 factors. Finally, the result of this match was brought in order to critically understand and provide a guideline to contractor in preparing EOT application and choose reliable factor based on the specific circumstances of project delay factors thorough review conducted to reveal the nature of EOT application techniques. Doi: 10.28991/cej-2021-03091679 Full Text: PDF

Nowadays, delays in project often occur and cause various losses both for service providers and users. For the contractors, delays create the project cost overruns due to project overtime and can decrease contractor credibility in the future. This study aims to analyze a project delay by minimizing the work delays earlier. The analysis of a hotel building planning regarding the cost and time delays is done qualitatively by distributing questionnaires to the contractors and processing the responses using the SPSS software. The results of the S curve analysis and 30 factors that caused the project delay were identified and indicated that there was a delay value of 1.26% with five variables that most contributed to the delay in the construction project at PT. Wijaya Kusuma Contractors, i.e. reworking due to construction errors, low coordination between contractors and stakeholders, late material delivery, and equipment shortages.

One of the key tasks of an investor and a contractor at the stage of planning and implementing construction works is to measure the progress of execution with regard to the planned deadlines and costs. During the execution of construction works, the actual progress of the works may differ significantly from the initial plan, and it is unlikely that the construction project will be implemented entirely according to the planned work and expenditure schedule. In order to monitor the process of deviations of the deadline and the budget of the investment task, several rudimentary methods of planning—as well as the cyclical control of the progress of construction projects—are used. An effective tool for measuring the utilization of the financial outlays of a construction project is the presentation of the planned financial flows on a timeline using a cumulative cost chart, the representation of which is the S-curve. The purpose of this paper is to analyze the course of an sample construction project comparing the planned costs of the scheduled works with the actual costs of the performed works, as well as identifying the reasons leading to the failure to meet the planned deadlines and budget of the project implementation. As part of the research conducted at a construction site of a hotel facility, the authors of this paper analyzed each of the 20-month effects of financial expenditures on construction works that were developed and processed by the Bank Investment Supervision (BIS) over a period of three years (between 2017 and 2019). Based on these results, charts and tables of the scheduled and actual cumulative costs of the completed construction project were prepared, the careful analysis of which enables interesting conclusions to be drawn.

Abstract— Construction projects are a series of activities that have a time at the beginning and end time with the aim of realizing the idea into a physical form or building. Labor is one of the important resources, because often the supply is limited, both because of quality and other things. With a good workforce management impact on the completion of construction projects. But in the construction phase, contractors often experience many problems related to the construction project's labor allocation. This study uses the help of Microsoft Project 2007 application to create a network of Precedence Method Method (PDM) methods, then generate a bart chart for the preparation of a project implementation schedule or S schedule (time schedule) so that a histogram can be obtained after a leveling process is needed. The results of data analysis with a case study of the Bank Mandiri Development Project Palembang Office Building, it can be concluded leveling shows that the workforce needs are far less than previously planned. The number of planner workforce based on planner consultant data and reports is 8681 people and from the research results based on data processing the leveling process is only 7754 people. Keywords—: S curve; labour, histogram; Microsoft Project.

Purpose The management of building information modeling (BIM)-enabled construction projects is challenging and unstructured in nature, particularly in terms of contract administration. Even though previous studies have revealed various legal issues related to BIM, little is known regarding the contractual practices of BIM. Hence, the purpose of this paper is to explore the contractual practices between the BIM consultant and employer in detail. Design/methodology/approach An explanatory case study was carried out on four large BIM-enabled construction projects in China. Findings The contractual practices differed from one project to another in terms of ownership and intellectual property rights (IPRs) of the BIM model, roles of the BIM consultant, liability of the BIM consultant in the event of errors and delays of the BIM model, and BIM-related costs and payments. Some of the interesting findings are as follows: the employer shall retain the ownership and IPRs of the BIM model, the BIM consultant shall provide a warranty to ensure usability of the BIM model after project handover, the BIM consultant shall pay for damages or losses if the BIM model fails to deliver and the costs of BIM implementation shall be borne by both contracting parties. Originality/value This study provides a fresh, realistic insight on the development of plausible contractual practices between the BIM consultant and employer and the findings can be used to improve BIM contract protocols in future projects.

In a recent essay published in this journal, I illustrated the limitations one may encounter when sequencing texts temporally using s-curve analysis. I also introduced seriation, a more reliable method for temporal ordering much used in both archaeology and computational biology. Lacking independently ordered Biblical Hebrew (BH) data to assess the potential power of seriation in the context of diachronic studies, I used classic Middle English data originally compiled by Ellegård. In this addendum, I reintroduce and extend s-curve analysis, applying it to one rather noisy feature of Middle English. My results support Holmstedt’s assertion that s-curve analysis can be a useful diagnostic tool in diachronic studies. Upon quantitative comparison, however, the five-feature seriation results derived in my former paper are found to be seven times more accurate than the single-feature s-curve results presented here.

This case study is about misselling of insurance policies and associated ethical challenges in a leading insurance company. Pro-organisational ethical violations mostly remain unnoticed and are often protected by implausible explanations. In the long run, persistent rationalisation makes malpractices a norm. The present work describes the interventions applied by a consulting firm to bring behavioural integrity. The consulting firm found that socialisation, rationalisation and institutionalisation considerably influenced people’s behaviour at the workplace and normalised unethical behaviour of insurance agents. It architected the behaviour of salespeople by specifically designed interventions through self-control mechanism and nudges. These interventions developed integrity in employees and reduced the number of cautions, warnings and terminations.
