Request for information (RFI) is considered as one of the important administrative tools in construction projects. It can be used as an indicator on how well the coordination between parties, especially between contractors and engineers and/or supervisors, performed in a project. Delays in a construction project could be identified by analyzing the RFI documents, but on the other hand, they could also be caused by poor administrative in handling the RFI documents and by delays in processing RFIs. This paper reviews the performance of four building projects in handling their RFI documents. The four buildings were constructed by a national joint-operation contractor, designed and supervised by an international joint-operation consultant. The RFI responses and wok-in-process were used to measure the project’s performance in handling the RFI documents; from the contractor’s and the engineer’s point of views. The analysis results show that the engineer had been very responsive in processing RFIs, while the contractor had difficulties. In general, the contractor was lack of capable personnel in handling RFIs for all four buildings. Moreover, communication problem was the key of the project’s performance due to different language and culture. The authors believed that the results of the analysis would influence to the overall project performance.

The Relationship

Expect for formal contracts, there are informally unwritten psychological contracts (PC) in the relationship between buyer and supplier for construction projects. The PC can affect the construction project performance and even cause project failure, but its process and formation are complex and not comprehensive in existing researches. This paper analyzes the PC between buyer and supplier by using evolutionary game and repeated game to tackle this gap. The results show the following: (1) the goodwill and interest have an important impact on PC fulfillment. (2) The PC is vulnerable; for example, once either one fails to perform PC, the other will also destroy PC, and then the construction project will enter a vicious circle. (3) In the process of repeated game, the effect of goodwill will gradually disappear, and the interest will play a major role. (4) If the project performance is only linked to one participant, it will lead to breach from another player. Some measures may help both sides to complete PC, such as making both sides profitable, increasing the emphasis on business reputation, and improving the relevance of construction projects performance.

WBS (Work Breakdown Structure) plays an important role in every construction project. WBS is a hierarchy of decreasing scope of work to become the smallest level called a work package, making it easier in the process of project management and control. The current problem is that many contractors in Indonesia, both large and small contractors, do not understand the importance of using WBS in a construction project. This causes project performance to be less than optimal, especially on cost and time performance. Currently, WBS standards have been developed for building projects. In this study will look at the cost and time performance of the project from the use of WBS standard building. The sample used in this study are projects that have applied the use of project standards. The projects include Building X, Lecture Building Y, and Sports Facility Building Z. The method used in this study is the EVM (Earn Value Method) approach, collecting data using questionnaires. The results showed that using the WBS standard had an effect on cost and time performance. Good cost and time performance is shown in the Building X and Lecture Y buildings. While the cost and time performance of the Z Sports Facility Building tends to be unstable. This is because the work items that exist in the WBS standard are not in accordance with the project conditions, so it is necessary to adjust work items.

Work Method

The implementation of a construction project consists of several works that carried out by labourer or craftsman in accordance to their specifications of expertise. To achieve both time and quality target of work output, each craftsman use different work method that consists of a series of activities. From a series of activities that carried out by each craftsman, the time needed to complete a work can be calculated. This study observed the activities of bricklayers in tile installation. The method that used in the study of bricklayers in tile installation is a literature study. On the other hand, an on-site study is performed by recording a number of bricklayers in tile installation. The recordings of each bricklayer were studied so that a series of activities and the activity time of tile installation can be obtained. From the observations of 35 bricklayers regarding work method and activity time of the tile installation, 4 (four) work methods were identified. Of all the samples that have been studied, the fastest is the bricklayer number 9 (nine) whose activity time was 7.69 minutes by using the work method number 2 (two).

Many interfaces typically exist in the construction phase of a project. Since project participants usually fail to share interface information, most interfaces are difficult to solve effectively during that phase. Furthermore, future activities might not be implemented based on changes made by predecessors. In practice, failure to manage interfaces may result in additional work or in low project performance. In order to manage construction interfaces effectively, this study proposes the novel Multilevel Interface (MI) Matrix approach to enhance interface management during the construction phase of construction projects. By using the MI matrix approach, construction interface issues will be tracked and man-aged easily and effectively. Furthermore, this study develops a construction web matrix-based interface management (WMIM) system integrated with the proposed MI Matrix approach. The MI matrix approach and WMIM system are applied to a pilot test to illustrate how to support interface management during the construction project. As results of the pilot test indicate, the MI matrix approach and WMIM system provide an effective interface management tool for the construction phase. Santrauka Statybos projekto statybos darbų etapui būdinga tai, kad su įvairiais subjektais palaikoma gausybė ryšių. Daugumą jų šiame etape veiksmingai palaikyti dažniausiai ne itin lengva, nes projekto dalyviai paprastai informacija apie juos nesidalija. Be to, perimantys darbą gali ir nesiremti savo pirmtakų padarytais pakeitimais. Praktine prasme nesugebant valdyti ryšių, gali tekti darbus perdaryti arba projekto efektyvumas gali sumažėti. Efektyviam su statyba susijusių ryšių valdymui šiame darbe siūlomas novatoriškas įvairialygių ryšių (ĮR) matricos metodas, leidžiantis pagerinti ryšių valdymą statybos projekto statybos darbų etape. Taikant ĮR matricos metodą lengva veiksmingai sekti ir valdyti statybų ryšių klausimus. Be to, atliekant tyrimą sukuriama projekto dalyviams skirta internetinė matricinė statybų ryšių valdymo (WMIM) sistema, į kurią įtrauktas siūlomas ĮR matricos metodas. Taip pat, taikant ĮR matricos metodą ir WMIM sistemą, atliekamas bandymas, rodantis, kaip jie padeda valdyti statybos projekto ryšius. Bandymo rezultatai rodo, kad ĮR matricos metodas ir WMIM sistema – tai efektyvi ryšių valdymo priemonė statybos darbų etape.

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.

PurposeThe Project Management Body of Knowledge recommends the use of issue logs as a best practice to minimize the potential project cost and schedule growth. Although the broader topic of project control has been widely studied in the construction literature, the specific application of issue logs has remained relatively understudied. This study aims to analyze the extent and consistency with which construction teams utilize issue logs and the corresponding project performance outcomes.Design/methodology/approachA dataset of 5,635 individual issues was gathered from the final issue logs of 881 small building projects delivered via the design–bid–build method. Differences between groups were determined using the Kruskal–Wallis H test with post hoc testing via the Mann–Whitney U test with pairwise comparison.FindingsThe results showed that, on average, project teams who used issue logs to a greater extent achieved a 3.1 to 4.3% reduction in cost growth and a 5.3 to 12.3% reduction in schedule growth. This result shows that issue logs can be used to improve construction project performance in the areas of cost and schedule.Originality/valueThis result provides a contribution to practitioners, wherein project teams should be encouraged to establish their issue management practices early in the project schedule to encourage greater issue log usage for the remainder of the project.

Performance of a construction project could be influenced by a number of attributes, especially large and complex projects lay additional focus on the success / failure attributes, because of the intensive amount of money invested, a high degree of uncertainty, the complexity of personnel’s required, a multiplicity of goals and problems in coordination between different stakeholders encountered. In this research paper, the author intended to define and examine the relationship and impact of construction productivity (CP) over construction project performance (CPP). The author tests the proposition that there is a positive relationship/impact between both of them. And to test the effect of factors is affecting CP on CPP and to propose a conceptual model on the basis of the analysis. To validate the mathematical validity of factor analysis, Spearman correlation analysis has been performed on the factors. And to check the reliability of all the factors using reliability analysis, and finally test the hypothesis that construction productivity is having a positive impact on project performance using one sample t-test. The findings of the study concluded that there is a positive impact of construction productivity on project performance in Indian construction projects. This paper attempts to identify the relationship between CP and CPP and recommends the framework for the industry to grow sustainably and deliver projects successfully. This study is conducted using a structured questionnaire survey in India and to validate the results of the study similar kind of study is required to be conducted in the other regions of the country to have more reliable findings."This paper is the revised version of the paper that has been published in the proceedings of the Creative Construction Conference 2018: Dixit, S., Mandal, S.
