Compared to other industries, the construction industry is slow to take advantage of the benefits of digitalization. There are many different parties involved in projects, which makes it a versatile but also fragmented industry, which in this case is not to its advantage. Building information modeling (BIM) is a tool that could improve the cooperation between these parties and which has many other benefits associated with it, such as time- and cost savings. Quantity take-off in BIM is something that can be carried out at a low degree of maturity and is considered to be one of the most useful working methods that BIM enables. Despite the many benefits that studies have shown, many companies in the construction industry have still not fully implemented a working method where BIM is used for quantity take-off.The purpose of the project is to investigate the BIM use among parties in the Swedish construction industry. More specifically, this study will examine the working methods of medium-sized construction companies with quantity take-off. Since the work with quantity take-off has been shown to be linked to more basic BIM use, this factor can be seen as a good indicator for the development of BIM within companies. Medium-sized construction companies have been chosen as they are a good representative of the large mass of parties in the construction industry who have both the capacity and the finances to implement BIM. Furthermore, this project also aims to locate the difficulties in using these digital working methods for quantity take-off.The study is performed as a qualitative case study where ByggDialog AB exemplified a medium-sized construction company in the construction industry. In semi-structured interviews, employees were asked to answer questions concerning the subject of the study.The results of the study have shown that the willingness to develop working methods with BIM at medium-sized construction companies exists, but that visions and ambitions are limited by the adjustment costs that a BIM-implementation would entail. The fact that there are no requirements or demands from customers is another factor that contributes why BIM is not used more today. As a result of the fact that the customers today are not prepared to finance a BIM-implementation, the development is not driven further within the studied company.In this case study, we have identified that the studied medium-sized construction company does not use BIM for quantity take-off. This is not due to that the contractors do not want to, but because it is difficult to motivate that a BIM-implementation would cover the costs involved. This study therefore indicates that in the short term it is not profitable to implement BIM as it entails large conversion costs for companies. / Byggbranschen är jämfört med andra branscher långsam på att utnyttja de fördelar som finns med digitalisering. Det är många olika aktörer inblandade i projekt vilket gör det till en mångsidig men även fragmenterad bransch, vilket i det här fallet inte är till dess fördel. Building information modeling (BIM) är ett verktyg som skulle kunna förbättra samarbetet mellan dessa aktörer och som har många andra fördelar kopplat till sig såsom tids- och kostnadsbesparing. Mängdavtagning i BIM är något som kan genomföras vid en låg mognadsgrad och anses vara en av de mest användbara arbetsmetoderna som BIM möjliggör. Trots de många fördelar som studier påvisat har många företag inom byggbranschen fortfarande inte fullt ut implementerat ett arbetssätt där BIM används vid mängdavtagning.Syftet med examensarbetet är att undersöka BIM-användningen hos aktörer i den svenska byggbranschen. Mer specifikt kommer detta examensarbete att granska medelstora entreprenörers arbetssätt med mängdavtagning. Eftersom mängdavtagning har visats vara kopplat till mer grundläggande BIM-användning kan denna faktor ses som en god indikator för utvecklingen av BIM inom företag. Medelstora entreprenadföretag har valts då dessa är en god representant för den stora massan av aktörer inom byggbranschen som både har kapaciteten och ekonomin att implementera BIM. Vidare syftar detta examensarbete också till att lokalisera svårigheterna vid användning av dessa digitala arbetssätt för mängdavtagning.Studien är utförd som en kvalitativ fallstudie där ByggDialog AB fått exemplifiera ett medelstort entreprenadföretag i byggbranschen. Medarbetare har i semistrukturerade intervjuer fått svara på frågor som berör studiens ämne.Resultatet i studien har visat att viljan att utveckla arbetssätt med BIM hos medelstora entreprenadföretag finns men att visioner och ambitioner begränsas av de omställningskostnader som en BIM-implementering skulle medföra. Att det inte finns någon efterfrågan eller krav från beställare är en annan faktor som spelar in i varför BIM inte används mer idag. Som en följd av att beställarna idag inte är beredda att finansiera en BIM-implementering så drivs inte utvecklingen vidare inom det studerade företaget.Vi har i denna fallstudie identifierat att det studerade medelstora entreprenadföretaget ej använder sig av BIM vid mängdavtagning. Detta beror inte på en ovilja hos entreprenörerna, utan för att det är svårt att argumentera för att en BIM-implementering skulle täcka de kostnader som det innebär. Denna studie indikerar därför att det på kort sikt inte lönar sig att implementera BIM då det innebär stora omställningskostnader för företagen.

En el presente artículo científico se muestra la problemática que existe en la gestión de equipos compartidos por una mala programación y control a través del estudio de un multiproyecto. Se identifica la metodología aplicada para poder proceder al diseño del software GesZech con la finalidad de poder mejorar la problemática y estar a la atura de los programas existentes en la actualidad.

En la empresa donde se ha realiza la implementación aumenta el rendimiento de los equipos en un 10% y mejorar el control en campo en un 30% a partir de su aplicación. / This scientific article shows the problems that exist in the management of shared equipment due to poor programming and control of these through the study of a multiproject. The methodology applied is identified to be able to proceed to the design of the GesZech software in order to be able to improve the problem and be up to date with the programs that currently exist. This tool is based on the critical chain method and uses Gantt charts because of the scheduling carried out. It also has options to control compliance with the team's execution and measure its performance through indicators; Furthermore, all changes made can be observed in real time. In the company where the implementation has been carried out, the performance of the equipment increases by 10% and improves control in the field by 70% from its application. / Trabajo de investigación

The construction industry is generally characterised by limited implementation of green logistics. With that in mind, this study aimed to examine the nature and extent of green logistics practices in large construction companies in Botswana. Although empirical studies have analysed green supply chain in the construction industry, most of them have not addressed the challenges and prospects of adopting green logistics by construction companies in a developing country like Botswana. Project Managers were interviewed after which a thematic analysis was used to interpret the qualitative results. Thereafter, a comparative analysis was done between the results obtained from the interviews and from extant literature. The findings showed that the adoption of the green logistics strategies was aligned more to economic reasons than environmental ones. The findings further showed that until and unless the construction, technical and administration issues are addressed, the adoption of green logistics will continue to be a challenge for the construction industry in Botswana / Centre for Transport Economics, Logistics and Tourism / M.

Оценка вероятности банкротства является важной задачей для предприятий строительной отрасли и имеет первостепенное значение, особенно в условиях перехода на проектное финансирование и введения эскроу-счетов. Целью магистерской диссертации является совершенствование методического подхода к оценке вероятности банкротства строительных предприятий. В работе рассматриваются понятия банкротства и несостоятельности, исследуются различные методики оценки вероятности банкротства, а также оценивается их применимость к строительным компаниям. В качестве источников использовалась научно-исследовательская и методическая литература, нормативно-правовые акты и финансовая отчетность организаций в открытом доступе. В магистерской диссертации был разработан методический подход к оценке вероятности банкротства строительных компаний, в основе которого лежит построение logit-модели, которая учитывает специфику финансовых показателей за счет обязательного использования эскроу-счетов, а также различия в возрасте, размере компании, кредитной истории, практическое применение которого повысит точность и объективность расчетов при оценке вероятности банкротства в краткосрочном периоде, как для внутренних, так и для внешних пользователей. / Estimating the probability of bankruptcy is an important task for the construction industry and is of paramount importance, especially in the context of the transition to project financing and the introduction of escrow accounts. The purpose of the master's thesis is to improve the methodical approach to assessing the probability of bankruptcy of construction enterprises. The paper discusses the concepts of bankruptcy and insolvency, explores various methods for assessing the probability of bankruptcy, and evaluates their applicability to construction companies. As sources, research and methodical literature, legal acts and financial statements of organizations in the public domain were used. In the master's thesis, a methodical approach was developed to assess the probability of bankruptcy of construction companies, which is based on the construction of a logit model that takes into account the specifics of financial indicators through the mandatory use of escrow accounts, as well as differences in age, company size, credit history, practical application which will increase the accuracy and objectivity of calculations in assessing the probability of bankruptcy in the short term, both for internal and external users.

M. Tech. (Department of Cost and Management Accounting, Faculty of Management Sciences), Vaal University of Technology. / Working capital management is an important aspect in the business in order to meet its daily activities. Permanent working capital, temporary working capital, gross working capital and net working capital are four types of working capital. The construction industry, as compared to any other industry, plays an important role in the economic growth of the country. The construction industry is regarded as the largest employer in the labour market and appropriate management of liquidity is essential. Construction contracts are divided into lump sum contracts, unit price contracts and cost plus a fee contracts and have the following role players: employer, employer’s representative, professional team, contractor, sub-contractor and adjudicator. This study analysed the relationship between working capital management and financial performance of JSE listed construction companies during the period 2009-2019. Annual financial statements, which included statement of financial position and statement of financial performance of all listed construction companies during the period 2009-2019 were extracted from the external database (IRESS) to obtain the data needed for statistical analysis. This study used a quantitative research method to analyse the relationship between working capital management and financial performance. Multiple linear regression and correlation analysis were used in this study with inventory conversion period (ICP), average collection period (ACP) and average payment period (APP) as independent variables and return on assets (ROA), return on equity (ROE) and gross operating profit (GOP) as dependent variables, in order to analyse the relationship between working capital management and financial performance of JSE-listed construction companies during the period 2009-2019. Results of this study indicated that working capital management has little or no influence on the financial performance of JSE-listed construction companies, therefore, this indicates that listed construction companies in South Africa need to manage their working capital properly by putting some new policies in place on their accounts payables and receivables, in order to have a relationship between working capital management and financial performance.
