The Lean concept was applied for the first time in the Toyota Production System (STP). Where it was used as a tool to increase productivity by eliminating waste. The term Lean Construction is an application of this philosophy in the construction industry. This article reports a case of the implementation of Lean Construction at a construction site where a kilometer of pipes for the drainage of rainwater from the retaining boxes of a company in the transportation of fuels and a condominium located in west of Manaus. The methodology used for this study was on-site observation, that is, visits were made to monitor the construction site routine to detect the problem and later propose a solution. The pattern of civil construction prevalent in Brazil still generates high rates of waste and other problems involving labor, delivery time, quality among other factors. Therefore, the Lean Construction philosophy has advantages for the civil construction industry because it can provide a more efficient service, reducing waste, increasing productivity and quality control.

Since robotics is becoming increasingly widespread in the construction industry, more phases and working steps should be investigated for their applicability to automation. Ideally, only few robot systems would be needed and thus be multifunctional.Current robot systems are used almost exclusively in precast construction. At the construction site, only prototypes are in use, and only individual parts of the building shell construction and assembly can be handled.This paper examines to what extent robots can be applied for the installation of fastenings and which boundary conditions exist or need to be addressed. Automated construction, and more precise installation of fastenings, has been partially implemented, which has been shown to increase productivity as well as installation quality, and therefore the components’ structural safety. This knowledge must now be extended to robots. The present work is based on an overview of current research and development and includes a discussion on the current research at the University Duisburg-Essen on a cable robot for brickwork construction. It further demonstrates that fastenings pose an important additional application, especially to ensure the changeover to other building materials. These can be built-in parts, but also brickwork connections or prefabricated parts.It can be assumed that robots will become increasingly important in the construction industry for reasons that include high quality, safety, speed and economic aspects.This is an extended paper of the Creative Construction Conference in Budapest on “Examination of Advanced Fastening Systems for the use of Robots in the Construction Industry” (Spyridis et al., 2019).

Abstract Quality control inspection is an imperative procedure in the construction industry. During construction, to get the plaster clearance of a specified area, the quality control engineer has to validate the mechanical, electrical and, plumbing (MEP) provisions laid out in the construction site with an engineering drawing approved by the consultant. The proposed system illustrates the implementation of an autonomous mobile robot (AMR) for inspecting MEP provisions amidst the construction phase. Power distribution, heating, ventilation, air conditioning (HVAC), telecommunications, water supply, and drainage are few examples of MEP engineering subsystems. In this paper, the main focus is on the inspection of plumbing services. These include provisions for washbasin and faucet in washrooms and sink in the kitchen area. The feedback program generated gives the evaluation result on the count of plumbing provisions inspected.

Purpose Construction management is ameliorated by the lean construction concept in many direct and indirect ways to reduce waste of construction process and improve the value. The purpose of this paper is to identify the challenges of the implementation of lean construction in the Bangladeshi construction industry and to prioritize these factors that constitute these challenges. Design/methodology/approach A comprehensive literature review was used for shorting the global challenges of implementing lean construction. Subsequently, these challenges were incorporated into a structured questionnaire for survey. A total of 164 valid responses were collected from Bangladeshi construction practitioners involved in different types of construction organizations. The results were analyzed using the Relative Important Index (RII) and Mann–Whitney U test. Findings The findings revealed 41 challenges of lean construction implementation in the Bangladeshi construction industry. The highest ranking challenges are the lack of awareness about lean construction, lack of skills, training and lean techniques, unwillingness to change the existing culture, lack of management commitment, fragmented and cyclic nature of the construction project and unavailing communication between all project participants. The study also discusses some universally applicable solutions to overcome these challenges. Originality/value By the findings of this study, the Bangladeshi construction industry could get a new insight into the challenges of implementing lean construction. It could play a very important part in the body of knowledge, as it reveals the challenges of implementing lean construction for the first time with the socio-economic context of Bangladesh. Exploring the findings, the study could help the stakeholders, companies, academician, researchers and government to focus their effort and resources on the significantly appropriate issues. Furthermore, this study may beneficial to those developing countries especially in South Asia, who have shared the same socio-economic status with Bangladesh.

Purpose There is little information existing about the spread of lean among Jordanian construction companies. Building on a report by Diekmann et al. (2004), this paper aims to perform a similar investigation among first-grade Jordanian construction companies to assess the extent of implementation of lean techniques. Design/methodology/approach For this purpose, a quantitative approach to measuring contractors’ conformance to lean practices was adopted. A survey of 61 contractors was conducted using both e-mails and personally delivered surveys that were completed on the spot. The results were analysed, and a practice value index, which indicates the level of implementation, was figured out for lean practices. In addition, an analysis of variance was conducted to determine whether there were differences among respondents from different construction fields. Findings The survey indicated that some procedures used by Jordanian contractors were consistent with lean construction practices. However, there was no proof that lean concepts were used on a company-wide basis. Furthermore, the survey revealed that the Jordanian construction industry lacks a “continuous improvement“ mentality, suffers from the absence of error proofing devices and provides minimal training at several levels of the organisation. Originality/value The outcomes of the study are valuable for contractors and developers of management practices, as it will encourage them to adopt lean construction holistically and identify features that are not exploited in the Jordanian construction industry.

Penjadwalan merupakan aspek yang sangat penting karena didalamnya terdapat elemen perencanaan dan pengendalian produksi bagi suatu perusahaan yang dapat mengirim barang sesuai dengan waktu yang telah ditentukan, untuk memperoleh waktu total penyelesaian yang minimum. Masalah utama yang dihadapi oleh PT. ML adalah keterlambatan penyelesaian order yang mempengaruhi delivery time ke tangan costumer karena pelaksanaan penjadwalan produksi dilantai pabrik belum menghasilkan makespan yang sesuai dengan order yang ada. Oleh kaena itu dituntut untuk mencari solusi pemecahan masalah optimal dalam penentuan jadwal produksi untuk meminimisasi total waktu penyelessaian (makespan) semua order. Dalam penelitian ini, penjadwalan menggunakan metode Simulated Annealing (SA) diharapkan dapat menghasilkan waktu total penyelesaian lebih cepat dari penjadwalan yang ada pada perusahaan.   Scheduling is a very important aspect because in it there are elements of planning and production control for a company that can send goods in accordance with a predetermined time, to obtain a minimum total time of completion. The main problem faced by PT. ML is the delay in completing orders that affect delivery time to customer because the implementation of production scheduling on the factory floor has not produced the makespan that matches the existing order. Therefore, it is required to find optimal problem solving solutions in determining the production schedule to minimize the total time of elimination (makespan) of all orders. In this study, scheduling using the Simulated Annealing (SA) method is expected to produce a total time of completion faster than the existing scheduling in the company.

The book is about one of the biggest economic success stories that one has hardly ever heard about. It is about a perennially backward, poor, and peripheral country, which over the last twenty-five years has unexpectedly become Europe’s and a global growth champion and joined the ranks of high-income countries during the life of just one generation. It is about the lessons learned from its remarkable experience for other countries in the world, the conditions that keep countries poor, and challenges that countries need face to grow and become high-income. It is also about a new growth model that this country—Poland—and its peers in Central and Eastern Europe and elsewhere need to adopt to continue to grow and catch up with the West for the first time ever. The book emphasizes the importance of the fundamental sources of growth—institutions, culture, ideas, and leaders—in economic development. It argues that a shift from an extractive society, where the few rule for the benefit of the few, to an inclusive society, where many rule for the benefit of many, was the key to Poland’s success. It asserts that a newly emerged inclusive society will support further convergence of Poland and Central and Eastern Europe with the West and help sustain the region’s Golden Age, but moving to the core of the European economy will require further reforms and changes in Poland’s developmental DNA.

Your bed shall be the moorcock’s, and your life shall be like the hunted deer’s, and ye shall sleep with your hand upon your weapons.’ Tricked out of his inheritance, shanghaied, shipwrecked off the west coast of Scotland, David Balfour finds himself fleeing for his life in the dangerous company of Jacobite outlaw and suspected assassin Alan Breck Stewart. Their unlikely friendship is put to the test as they dodge government troops across the Scottish Highlands. Set in the aftermath of the 1745 rebellion, Kidnapped transforms the Romantic historical novel into the modern thriller. Its heart-stopping scenes of cross-country pursuit, distilled to a pure intensity in Stevenson’s prose, have become a staple of adventure stories from John Buchan to Alfred Hitchcock and Ian Fleming. Kidnapped remains as exhilarating today as when it was first published in 1886. This new edition is based on the 1895 text, incorporating Stevenson’s last thoughts about the novel before his death. It includes Stevenson’s ‘Note to Kidnapped’, reprinted for the first time since 1922.

First Time

Abstract When in 1955/1956, for the first time in divided postwar Germany, a major Picasso exhibition took place in Munich, Cologne, and Hamburg, it came to be a cultural event that reached and emotionalized the German audience, media, and sciences to an unprecedented extent. The exhibition Picasso 1900 – 1955 contributed significantly to the popularization of Picasso at all levels of society and gave the German people access to modern art on a much wider scale than the first documenta held concurrently in Kassel. The undisputed eye-catcher of that spectacular exhibit was Guernica, on display in Germany for the first and only time. Its controversial reception reveals that at that time there was no intention to see the work in Germany in a memorial relationship with Germany’s own historical responsibility. Thus it virtually functioned as a symbol for a collective amnesia of the West German postwar society, whereas the socialist East of the Republic stylized the painting into an anti-fascist icon.
