The Impact

Construction projects in all regions continues to be developed for the creation of facilities that can be utilized by the community. One of them is the construction of apartments which are now being intensively carried out to meet residential needs for the community. Making a construction project plan always refers to estimates that exist at the time development plan is made, therefore problems can arise if there is a discrepancy between the plans that have been made and the actual reality. So the impact that often occurs is the delay in the time of project implementation which can also be accompanied by an increase in the cost of implementing the project. In the construction project of Cinere Terrace Suites Apartemen & Citywalk, Jakarta there was a delay resulting in a late payment of monthly bill progress by the owner. Based on the above reasons, this research was conducted to find out how the project performance was seen from the cost and time period of the review period. how is the estimated cost and time to complete the overall project work. The method used in the analysis of this study is the Earned Value Method. Based on the results of the analysis carried out for 29 weeks the project performance on schedule has been delayed and cost shows a positive value. For the estimated completion time of the project there is an increase in time whose duration increases from the planned 98 weeks or 685 days to 109,624 weeks or 768 days. While the estimated cost of completing the project from the results of the analysis obtained a value of Rp. 270,147,448,569.16 smaller than the planned cost of Rp. 315,272,727,272.73. With the difference VAC of Rp. 45,125,278,703.57 this shows that there are benefits obtained by the contractor.

And Control

Material inventory management is one part of the logistics system devoted to project implementation on material procurement as per the needs plan procurement management is a very important material function, since the material inventory for a construction project involves a considerable investment cost. In general, every construction project involves complex activities, which involves the sharing of activities and operations. Material acquisition activities require good planning and control considering the large percentage of material costs to the total cost of the project. So if less effective material handling will result in loss of time, cost and quality. then this should receive high attention from contractors for the smooth and performance to be achieved in the implementation of construction projects.

Purpose The purpose of this paper is to study the interdependent boundary-spanning activities that characterise the level of permeability of knowledge, information flow and learning among construction supply chains involved in the delivery of building information modelling (BIM)-compliant construction projects. Construction projects are mobilised through a number of interdependent processes and multi-functional activities by different practitioners with myriad specialised skills. Many of the difficulties that manifest in construction projects can be attributed to the fragmented work activities and inter-disciplinary nature of project teams. This is nevertheless becoming ever more pertinent with the rise of technology deployment in construction organisations. Design/methodology/approach The study combined experts’ sampling interviews and a case study research method to help offer better insights into the kind of emerging multilevel boundary practices as influenced by the rapidly evolving construction technological solutions. The experts’ sampling helped inform better understanding by unravelling the key changes in contemporary boundary configurations and related boundary-spanning practices within technology-mediated construction project settings. The case study also helped to establish the manifestation of best practices for managing multilevel boundaries in BIM-enabled construction project organisations. Findings The study has revealed that different generic organisational BIM strategies as developed in specialised boundaries are reconfigured as appropriate at the project level to produce project-specific BIM execution plan (BXP). The outcome of project BXP is dependent on the project organisational teams that cooperate in creating new solutions and on conceding space for negotiations and compromises which conflicting interests at the project level can find to be both desirable and feasible. The implementation effort is therefore contingent on mutual translation in which different actors with different insights instigate their practice through negotiation and persuasion which eventually are reinforced by contractual agreements and obligations. Originality/value The paper has presented a novel and well-timed empirical insight into BIM-enabled project delivery and best practices that span multilevel boundaries of construction organisations.

Machine Learning Regression Techniques (MLRT) as a shrewd method can be utilized in this study being exceptionally fruitful in demonstrating non-linear and the interrelationships among them in problems of construction projects such as the earned value indexes for tall buildings projects in Republic of Iraq. Three forecasting models were developed to foresee Schedule Performance Index (SPI) as first model, Cost Performance Index (CPI) as a second model, and the third model is To Complete Cost Performance Indicator (TCPI) in Bismayah New City was chosen as a case study. The methodology is mainly impacted by the deciding various components (variables) which impact on the earned value analysis, six free factors (X1: BAC, Budget at Completion; X2: AC, Actual Cost; X3: A%, Actual Percentage; X4: EV, Earned Value; X5: P%, Planning Percentage, and X6: PV, Planning Value) were self-assertively assigned and agreeably depicted for per tall buildings projects. It was found that the MLRT showed good results of estimation in terms of correlation coeffi cient (R) generated by MLR models for SPI and CPI and TCPI where the R were 85.5%, 89.2%, and 86.3% respectively. At long last, a result tends to be presumed that these models show a brilliant concurrence with the genuine estimations.

Identification and rank of delay factors in construction projects depending on the project delivery system . The implementation of construction projects depends on many unpredictable factors, which can cause delays in construction works. The article proposes classification of the validity of delaydepending on the project delivery system. Two of them were considered: the traditional system (Design – Bid – Build), where the design stage is separated from the construction stage and the design and build (Design & Build), which consists in entrusting design works and carrying out works to one contractor. The order of validity is based on results of research carried out among participants of the construction project.

Changes will always occur in project construction and can not be avoided. Many factors can cause changes in the construction project. Most dominant factors of cause of changes in project construction is design change. Design changes will have bad impact on the performance of construction projects, especially the performance of cost and performance time. Many factors can be the cause of design changes. Knowing the factors that cause a design change and knowing its behavior is very important to do. Knowing factor and behavioral of design changes that occur in project construction, and then can be managed properly, it will can be reduce the occurrence of design changes in projects construction. With the reduction of design changes will be able to improve the performance of construction projects, especially at cost and time performance. Construction projects carried out by using a project delivery system. Each project delivery system used will have different contractual relationships, rules, and responsibilities of each party involved. These differences will lead to in the occurrence differences in design change in project construction. Selection of appropriate project delivery system to complete a construction project is needed. The purpose of this paper is to provide a conceptual framework that can be used to determine the behavior, and the effect of design changes on project construction at some project delivery system used.

Appropriate planning and effective monitoring of the execution of construction projects is important with regard to their successful sustainment of implementation. Time and cost are key elements that determine the success or failure of construction projects. The obtaining of a rational S-curve course before the start of a construction project that reflects reality is important for all the participants involved in implementing an investment task. The article proposes an original methodology for planning the course of the cumulative cost curve in construction projects. It uses a method of shaping the S-curve, which is well-known in both literature and practical approaches. On the basis of the authors’ own research carried out in a homogeneous research group of hotel facilities, the areas of the curve for the correct planning of costs in construction projects were designated, which determine the boundaries of the predicted costs accumulated over time. The data for the development of the authors’ research methodology is the result of the authors’ own experience and professional work. The authors carried out Bank Investment Supervision in the years 2006–2019 on behalf of the banks that grant investment loans for non-public contracts. Knowing the total cost and duration of the planned construction project, which were determined on the basis of project documentation, cost estimates, and also their own database regarding planned and completed deadlines and budgets of similar investments, 6th degree polynomials of the real costs of the construction works were determined. This approach enabled the correct planning of costs over time and the determination of planned monthly amounts of construction works to be executed.

PurposeIn an attempt to create national harmonisation of legislation, a set of model Work Health and Safety (WHS) Regulations were developed in Australia. These regulations require principal contractors to undertake specific WHS planning and coordination activities if the construction works to be completed cost AU $250,000 or more. However, there are some doubts about the usefulness of this monetary threshold. This study aimed to investigate how effective this threshold can be in Australia.Design/methodology/approachTo evaluate the performance and operation of this threshold in the Australian construction industry, this study modelled the costs of construction for four construction project scenarios – small classroom, two-storey home renovation with adjacent pool, small commercial warehouse and single-storey house (volume home builder) – under various conditions based on historical data (2011–2017) and in eight Australian jurisdictions.FindingsAmong the six study factors (i.e. the types for construction, geographical location, design specification, delivery method, contracting approach and inflation), the research found considerable variation in the operation and performance of the monetary threshold.Originality/valueThe research highlights some potential challenges associated with the use of a monetary threshold in the regulation of WHS planning in construction projects. Thus, the results are expected to contribute to addressing these challenges, leading to the development of an appropriate balance to achieve efficient and effective WHS regulation in Australia.

The Earned Value Method allows the prediction of future values of the total cost and duration of the construction project realization, and also it allows the early detection of the collisions between the schedule and the construction project budget. It is more often indicated its usefulness for monitoring and controlling the construction work progress in the time and cost formulation. It is used, in the indirect way, to control the risk in terms of the cost overruns of the construction project realization and in case of the failure to meet the deadline for completion of the construction project. The authors’ goal was not only to indicate the advantages of the method (widely discussed in the literature) but also to indicate some inaccuracies in the application of the Earned Value Method, which may affect the costs forecasting and the date of completion of the construction project. The conclusions are based on the analysis of several construction project realizations.
