House Building

The aim of this research is to analyze the empirical factors (executive indexes) in a house building project which has governmental employer, based on the opinions of practitioners of the projects. As a case study, a 624 units house building project was selected in Shiraz city. Identifying the challenges and the advantages of this project can help us to improve and solve problems of many similar projects, which are being constructed all over the country. Twenty two practitioners of the project were surveyed, based on the executive indexes, using a questionnaire. The responses were classified in two categories: 1) Managers and Experts (M&E) and 2) Consultants and Contractors (C&C). The completed questionnaires were assessed and analyzed and the values of indexes were calculated separately, based on the ideas of both groups. It is found that there is a similarity between the ideas of the two groups in 25 indexes out of 30. Furthermore, the difference between five other indexes is small, based on both group's ideas. It may show the accuracy in completing the questionnaire and the accuracy of the methodology used. In this paper the results of this case study are presented and discussed.

Construction industry suffers numerous issues and complicated factors like price, period, quality and safety. It is said that Construction projects are versatile because they associate with contractors, architects, advisers, designers, the project owners, etc. Keeping in view of above factors, objective of this research is to highlight those factors which have impact on labor productivity in house building project. Through literature review as well as discussion with different consultants, several factors of productivity were identified. Out of which 20 factors were selected, which were later categorized into two sets, for analyzing in the current study. A comprehensive questionnaire was prepared and sent to project manager, engineers, designers, and builders. It was found, that total expense of construction comes to much higher as it was originally calculated. It is suggested that human resource should be developed through an effective and well planned training program, so that construction project do not suffer due to low performance. The mentioned factors are supposed to help in completed the construction projects effectively.

Practical Recommendations

In the present demand-driven market, consumers play a key role. Players in the house-building market, as in other sectors, need to listen to the consumer's requirements – and these are continually changing. The real estate sector is rather rigid in its practices, yet those working in it will need to respond to the fluctuating wishes and demands of their consumers. One possible response is to adopt a flexible building strategy. Industrial Flexible Demountable (IFD) building has recently been a subject of debate in the Dutch construction sector. This is a special type of construction involving experimental projects, experimentation being the first step in optimising a renewed production process or product. The building process is currently subject to various construction-related and organisational obstacles. This means that, in some cases, the objectives (which are focused on consumer-oriented building practices) were not being achieved. It was necessary to identify the problem areas and to consider the available opportunities for optimising the building process in future IFD house-building projects. The results of this study have been incorporated into guidelines containing a step-by-step plan. This plan sets out practical recommendations for market actors who wish to initiate an IFD house-building project. This study's conclusions and recommendations form the basis for the seven stages that such parties will need to complete before starting on such a project.

Practical Implications

Purpose – This article aims to describe the development of industrialised house-building (IHB) to increase the understanding of the field. Design/methodology/approach – The study is based on an extensive literature study and a case study with three companies, studied between 2005 and 2013 which enabled an in-depth knowledge about the companies’ development within IHB. Interviews, observations and document studies are the main sources of information in the case studies. Findings – IHB is a complex field, consisting of several constructs that need to be integrated and continuously developed. Development of structured technical building systems has been central to the development of IHB along with developed production methods and processes. The interest in organisational fit or adaptation to industrialisation and strategy concerning business, production and products is increasing. This implies that IHB needs to be managed strategically and not on a building project level. Practical implications – The article gives an orientation on how leading companies have structured and organised their work within industrialisation, giving valuable advice to practitioners with interest in the field. Originality/value – This article describes the development of IHB based on studies of literature and three Swedish IHB companies’ development. This provides an aggregated view of the field’s emergence and unique information about the studied companies’ development.

Building Project

Adaptive reuse of buildings is considered a superior alternative for new construction in terms of sustainability and a disruptive practice in the current capital project delivery model for the renewal of today’s built environment. In comparison to green-field construction projects, adaptive reuse projects require distinct stages, definition of interfaces, decision gates, and planning methods in order to secure the success of the building project. Unfortunately, little research has been done regarding establishing feasible systems for the planning, assessment, and management of adaptive reuse projects, leading to underperforming building projects outcomes. Interface management (IM) can improve renovation projects outcomes by defining appropriate ways to identify, record, monitor, and track project interfaces. IM has the potential of bringing cost and time benefits during adaptive reuse projects execution. The aim of this study is to develop a reference framework for implementing IM for adaptive reuse projects. First, the inefficiencies of redevelopment projects are explained inside of a circular economy (CE) context. Second, an ontology of IM for adaptive reuse projects is defined based on the current barriers to adaptive reuse and the most common interface problems in construction projects. Third, the defined ontology is expanded through a case study by showing examples of adaptive reuse barriers on a case project, and how IM could have been part of the solution for these problems. Finally, this study concludes with the suggestions on interface management systems (IMS) implementation for future adaptive reuse projects.

For decision-making on the attributes and time weights existing in a dynamic intuitionistic fuzzy environment, a new ATS-generalized weighted intuitionistic fuzzy Bonferroni mean operator MADM model based on dynamic comprehensive time entropy and an ATS-generalized weighted intuitionistic fuzzy Bonferroni mean operator was established by taking into consideration the intrinsic correlations between attributes. An intuitionistic fuzzy decision matrix with the same time sequence was integrated into the model. According to the idea of “laying more stress on the present than on the past,” a time sequence weight considering both the subjective preferences and the objective information of samples was obtained to overcome the irrationality of subjective value assignment on existing time sequence weight and ideal time weighting. Based on dynamic comprehensive time entropy, the model not only reflects the degree of importance attached to the latest data but also gives consideration to the subjective preferences of decision-makers in order to set a new vector for time sequence weight. The dynamic intuitionistic fuzzy weighted operator was used to conduct aggregation to obtain a dynamic intuitionistic fuzzy comprehensive value, and the obtained results are sorted by the sorting function of intuitionistic fuzzy sets. The best alternative was selected and applied to a case study on green building project selection. The results indicate that the proposed method is comprehensive, scientific, and feasible.

Building life cycle is a process which covers not only the construction phase but also the feasibility, the design and the operation phases. Identifying the owner’s needs in all phases of this process is of paramount importance for achieving satisfactory results for the building project. Additionally, the owner’s needs should be fulfilled by the work scope of every stakeholder involved in the project. Nevertheless, these needs are not always adequately considered in building projects. Thus, the purpose of the research reported in this paper has been to develop a model that allows for the identification of the owner’s needs in all phases of the building life cycle. The article presents a six level classification system for the information required in the project and a two-dimensional model that maps the life cycle and the logical actions to be undertaken in each phase. The model has been corroborated and improved by applying the Delphi technique to a panel of ten experts in two rounds. The practical use of the model is through the systematic application of a series of questionnaires built upon the information classification system for determining the owner’s needs. The paper details the operation phase of the model as an illustrative example and a case study on a residential building project of twelve apartments in Spain.

Construction projects usually encompass numerous disciplines, requiring the integration of knowledge from civil, mechanical, electrical and other engineering domains. Some researchers contend that the integration of construction knowledge and experience at the early design phase would improve the overall project performance. Domination of tacit knowledge during design phase of building projects is the major source of knowledge flow problems between involved professionals. Therefore, this study intends to explicate the required mechanical and electrical knowledge which has to be considered during the conceptual design phase of a green building project. To fulfil this goal, a case study has been conducted to specify the entity of the required mechanical and electrical knowledge. The primary method for the data collection here is observation. Furthermore, this study employs the triangulation method in order to validate the collected data. The results contain the required mechanical and electrical knowledge which has to be considered during the conceptual design phase of a green building project.

The paper has investigated and established to what extent are preliminary estimates of building costs close to the lowestevaluated tender and how geographical proximity influences the variance between preliminary estimate and the lowestevaluated tender.A multiple case study constituting 43 building projects in Tanzania were statistically analysed covering a period from1995- 1999. Findings reveal a significant variance exists between the quantity surveyor’s preliminary estimate figureand the lowest evaluated tender; and that the variance between the quantity surveyor’s figure and the bidder is smallwhen the proposed building project is geographically closer to the quantity surveyor’s base. Analysis of variance (one -way) has shown geographical distance has a statistical significance on the variance between the preliminary estimatesand the lowest evaluated tender.The study has established that the object of preliminary estimates in building costs, that of making the client aware of hisfinancial obligations at early stages of a building project are not met fully.

Abstract Every port in Indonesia must have a Port Master Plan that contains an integrated port development plan. This study discusses one important aspect in the preparation of the Port Master Plan, namely the projected movement of goods and passengers, which can be used as a reference in determining the need for facilities at each stage of port development. The case study was conducted at a port located in a district in Maluku Province and aims to evaluate the analysis of projected demand for goods and passengers occurring at the port. The projection method used is time series and econometric projection. The projection results are then compared with the existing data in 2018. The results of this study show that the econometric projection gives adequate results in predicting loading and unloading activities as well as the number of passenger arrival and departure in 2018. This is indicated by the difference in the percentage of projection results towards the existing data, which is smaller than 10%. Whereas for loading and unloading activities, time series projections with logarithmic trends give better results than econometric projections. Keywords: port, port master plan, port development, unloading activities  Abstrak Setiap pelabuhan di Indonesia harus memiliki sebuah Rencana Induk Pelabuhan yang memuat rencana pengem-bangan pelabuhan secara terpadu. Studi ini membahas salah satu aspek penting dalam penyusunan Rencana Induk Pelabuhan, yaitu proyeksi pergerakan barang dan penumpang, yang dapat dipakai sebagai acuan dalam penentuan kebutuhan fasilitas di setiap tahap pengembangan pelabuhan. Studi kasus dilakukan pada sebuah pelabuhan yang terletak di sebuah kabupaten di Provinsi Maluku dan bertujuan untuk melakukan evaluasi ter-hadap analisis proyeksi demand barang dan penumpang yang terjadi di pelabuhan tersebut. Metode proyeksi yang dipakai adalah proyeksi deret waktu dan ekonometrik. Hasil proyeksi selanjutnya dibandingkan dengan data eksisting tahun 2018. Hasil studi ini menunjukkan bahwa proyeksi ekonometrik memberikan hasil yang cukup baik dalam memprediksi aktivitas bongkar barang serta jumlah penumpang naik dan turun di tahun 2018. Hal ini diindikasikan dengan selisih persentase hasil proyeksi terhadap data eksisting yang lebih kecil dari 10%. Sedangkan untuk aktivitas muat barang, proyeksi deret waktu dengan tren logaritmik memberikan hasil yang lebih baik daripada proyeksi ekonometrik. Kata-kata kunci: pelabuhan, rencana induk pelabuhan, pengembangan pelauhan, aktivitas bongkar barang
