Dissertação de Mestrado em Negócios Internacionais apresentada à ESTG - Escola Superior de Tecnologia e Gestão do Instituto Politécnico de Leiria.; The main objective of this dissertation is to analyze the effects of ethical behavior on a firm’s financial profitability. Corporate social responsibility has been used as an indicator of ethical performance. After analyzing the financial indicators ROA and PM, from a sample of the twenty biggest civil construction companies in Portugal, between 2007 and 2011, we conclude that ROA is significantly related to a firm’s ethical performance. However, we did not find any statistical evidence that relates PM to ethical performance. Although the scores are very low on all CSR indexes, we can conclude that companies, who are exporting, seem to be more concerned with environmental issue than ethical issues. The top management in the civil construction should take a deeper look into their CSR activities, and should not neglect the impact social inactivity may have on their financial performance. Although, there are some examples to look up to, there is still a long way to go for the majority of companies in this industry. Limitations and recommendations for future research are provided at the end of this dissertation.

The evolution of repetitive scheduling methods led to the introduction of the learning concept in construction planning. It is common knowledge that performing the same activity repeatedly, and in the same conditions, takes less and less time as the activity is repeated (Gates and Scarpa, 1972). This phenomenon is clear in many construction activities and is known as learning experience or learning effect. The increase in productivity is mainly due to the increasing knowledge acquired by work repetition. Graphic representation is through a learning curve that admits duration decreases as the activity is repeated, according to a predictable and constant learning rate. The Linear Model of logarithmic coordinates (log10Y 5 log10A – nlog10X) was applied to two repetitive construction processes, frequently used in Portuguese construction. The intent was to examine its applicability and efficiency in predicting future performances, and the interest in incorporating the model in new planning methodologies for repetitive construction. In both cases, learning processes were created.

The last few years have confirmed what was mostly feared: Portuguese construction industry suffers from a chronic disease - the lack of competitiveness. Symptoms have long been recognised in several construction projects: frequent delays, cost overruns, deficient safety, absent quality. The authors have been carrying out several studies whose aiming at are clarify reasons for the lack of competitiveness of national construction industry on the four items mentioned above. This paper occurs mainly about the aims of PhD` survey about construction delays. It has the following mains components: (1) to research and analysis bibliography and establish a common set of causes and background reasons for the problem; (2) to inquire to Portuguese construction stakeholders on the causes and background reasons for project delays following from their experience in recent projects; (3) to establish possible paths to solve the problem. The survey results appear to confirm the original list of causes for delays of the study. The mains reasons are related with designer problems, poor productivity, procurement system, overly optimistic planning, and frequent change orders during construction and so on. Thereafter, the paper will seek what could possibly be done and from which parties...

The lack of accomplishment of the main management functions in construction projects had been reported worldwide. The symptoms are well recognized, like cost and time overruns, defícient quality and lack of safety. To help clarifying the reasons for this evidence, several surveys were carried to Portuguese construction stakeholders by a team research of construction management of University of Minho. The PhD survey results to confirm the original list of causes for delays of the study namely poor productivity, procurement system, and frequent change orders during construction and so on. In order to correct the above problems and improve construction competitiveness should be implemented a national database with the quantity works list for different construction projects, a more appropriate and efficient organizational systems within design teams and a need for greater care on the part of the owners when they prepare their schedules and preliminary programs. On the other hand, it was clear that despite the apparent advantages of Internet survey approach, traditional methods like fax, phone calls and interviews appear to be most successful and still are preferred by respondents.; Fundação para a Ciência e a Tecnologia (FCT) - SAPIENS nº 47625; LEONARDO DA VINCI - Community vocational Training Action Programme Second Phase -project PL/04/B/P/PP/-174 417

Dealing with construction claims is a difficult task nowadays. Not only claims became an inescapable issue in construction project management but analysing and resolving them adequately raises a number of difficulties. The first step for overcoming this problem is an adequate claims classification and identification. In Portugal, previous studies had identified eight different types of construction claim each one of them covered a speciflc process of documentation, submission, quantification and settlement, in the scope of the Portuguese construction legal frame. In order to evaluate which type of claims are currently presented in construction projects concluded in Portugal, an internet based inquiry was settled to owners and contractors. The results indicate that changes claim, particularly the subtypes direct changes, indirect changes and errors and omissions, represents 64% of claims presented in the construction projects surveyed, and together with delay claims, represented an aggregated frequency of 84%. In respect to the amounts requested and paid, the ratio was 0.76.

The construction industry faces a wide range of challenges that ought to be addressed if it is to maintain and, if possible, improve its competitiveness. The key interrelated elements of competitiveness have been the focus of many international research projects and studies. The measurement of this success and the quality of the project’s performance depends on the achievement of the main construction management function objectives, namely time, cost, quality and safety, which are the focal indicators for a healthy and competitive construction sector. However, frequent delays, cost overruns, insufficient quality and lack of safety are symptoms of the lack of competitiveness recognized in most construction projects concluded in the last years in Portugal. As a result a research project has been launched to better understand and clarify the reasons behind die lack of achievements of these management functions that affect the competitiveness of the Portuguese construction industry. Results of the survey obtained so for indicate that the main causes for the lack of achievement of the construction functions are due to design and client responsibilities, inadequate construction management and lack of specific training.

The Portuguese construction industry is currently experiencing great challenges. Along with the redefinition of its legal framework, so as to make it more efficient and bring it up to date, the sector is going through stagnation in the private market and a slump in the public construction market, mostly on account of the current state of economy country. It is very important to find ways to correct the problems and to make the sector more competitive. Recently there have been several conferences, symposiums and publications which have studied the reasons for its lack of competitiveness. One of the main reasons that have been identified is the recurrent poor quality of project designs. Previous studies have often found that designs contain a lot of errors and omissions. This paper wills critically discussion the problem of poor quality design in Portugal using literature and data from a set of interviews with expert construction managers. The reasons for the poor quality of designs have been established from the outcomes of a national survey undertaken and a series of interviews of experts.

Most construction projects in Portugal do not fully achieve the main management functions, namely cost and time. Accordingly, the competitiveness of the Portuguese construction industry has been ranked fairly low. A survey was conducted among the main construction stakeholders to help clarify the reasons for this problem. The inquiry used for the survey focused on the characteristics of major projects concluded in the last years and on specific data on the attainment of cost and schedule objectives. Research revealed that clients and contractors agree that major causes for cost overruns were due to design errors, direct changes ordered by the client and different site conditions due to geological and geotechnical obstacles. Client liability, design problems and the project specifics were the main causes indicated by clients and contractors for project delays. However, clients also specified main responsibilities for project delays to inadequate construction management.

A survey was conducted among the main construction stakeholders to help clarify the reasons for this problem. The inquiry used for the survey focused on the characteristics of major projects concluded in the last years and on specific data on the achievement of quality and safety objectives. Research revealed that clients invoked poor task preparation, lack of specific training and the lack of individual protection as the main reasons for construction accidents, while contractors attribute responsibilities to the high risk of the activity. 80th clients and contractors indicate that poor work execution and inadequate design solutions are the main reasons for the lack of quality in construction. Additionally, contractors also attribute external factors and the inadequacy of materiais or products a major contribution for the lack of quality in construction.

Deconstructing a building is the careful dismantling of that building so as to make possible the recovery of construction materiais and components, promoting reuse and recycling. The concept arose as a consequence of the rapid increase in the number of demolished buildings and the evolution of environmental concerns within society at large. The deconstruction is a process unusual in Portugal; traditional demolition is yet the preferred method when it is necessary to dismantling a building. However there are studies under away whose purpose is to lessen the quantity of debris that are by-products of the construction processo The aim of this document is to present the current state of national research, implementation and viability of deconstruction as an innovative technique in the process of rehabilitation, thereby contributing towards the economic sustainability of said processo The research projects which authors are involved are also discussed.

The construction industry plays a very important role in the Portuguese economy. In 2009, it was among the top five economic sectors, representing 13% of total employment. Nevertheless, project failures are still frequent mainly due to inadequate management practices and to the intrinsic characteristics of projects of the construction industry. Even though Portuguese construction has improved in recent years, cost and schedule overruns, low productivity and final product quality problems are still common. In this context, project management is a crucial tool for improving construction operations and for the overall success of projects. The aim of this article is to contribute to the discussion on success evaluation factors in a field where little has been written – the construction industry. Through a survey of 40 medium and large Portuguese companies several factors were identified which are currently considered in the evaluation of project success, as found in the literature review. The results show that the traditional factors, often referred to as the “Atkinson elements triangle” (cost, time and quality), are still the most relevant for evaluating the success of a project, but others, such as customer involvement and acceptance...

Dissertação de mestrado em Engenharia Industrial; Tem-se verificado ao longo dos anos dificuldades ao nível da gestão dos projetos de construção, com sistemáticas falhas de cumprimento em termos de prazo, custo e qualidade, tal como vários estudos demonstram, o que torna necessária uma reflecção acerca dos fatores que podem estar na origem destas falhas. Perceber a maneira como os gestores de projeto planeiam os mesmos, no sentido de melhorar o desempenho e resultados, é por isso um fator importante. Existem já vários estudos que demonstram as dificuldades enfrentadas e os fatores que originaram as falhas e desvios, apontando para a incorreta gestão do custo e prazo como os fatores responsáveis pelo insucesso dos projetos. No entanto, é importante perceber se áreas além do custo e prazo do projeto recebem a devida atenção por parte dos gestores de projetos. Apesar de custo e prazo serem áreas mensuráveis, existem outros fatores que podem colocar em causa o projeto, logo desde o início. Este estudo surge no sentido de compreender os motivos que originam os desvios no custo, prazo e qualidade, do ponto de vista da gestão de projetos, olhando para as áreas de conhecimento, mencionadas pelo PMI (Project Management Institute). A recolha de dados foi efetuada através de um questionário online...

Dissertação de mestrado integrado em Engenharia Civil; As empresas de construção portuguesas tem vindo a sofrer um grande revés acompanhando, claro, a situação económica no nosso país, ao qual novas ideias de melhoria e renascimento são precisas para manter o fluxo de negócio ativo. A filosofia Lean Construction (LC) está em claro crescimento. Se falarmos nas empresas de todo o mundo, muitas delas já aplicam algumas ferramentas e técnica LC. Pelo contrário, Portugal ainda se encontra num patamar aquém do que seria esperado pois, uma grande parte das empresas ainda não tem conhecimento dos benefícios que esta filosofia traz a nível de todos os setores. O objetivo desta dissertação é perceber até que ponto esta filosofia é conhecida e está implementada nas construtoras portuguesas. Para tal, refletiu-se sobre os conceitos do Lean, com especial destaque para a abordagem à LC, bem com, uma breve comparação entre o uso das metodologias correntes e esta nova filosofia. Para concretizar o objetivo realizou-se um questionário às empresas de construção, onde se ficou a saber, em geral, o grau de conhecimento e o uso, ou não, desta filosofia.; The Portuguese construction companies has suffered a major setback...

The accidents in the construction are one of the main indicators of the claims recorded at work in Portugal. The identification of the factors and causes related with accidents at work is essential for a correct analysis of the risks and a consequent adoption of procedures and measures to achieve a more effective prevention. The focus on rehabilitation has increased in Portugal and it is in this kind of construction that accidents are more frequent, mainly motivated by the lack of local knowledge to work and skilled manpower. Thus, on the basis of an inquiry implemented to several categories of interveners, this work puts forward the main reasons for noncompliance in safety regarding this type of activity.

Dissertação de mestrado integrado em Engenharia Civil; A construção é uma atividade económica de grande importância, quer pelos bens que produz, quer pelas suas ligações a outros setores económicos. No entanto, em Portugal, o setor perdeu a relevância que tinha, devido à conjuntura altamente desfavorável que o país vive, marcada por uma crise do mercado interno, agravada, nos últimos anos do decénio passado, com as consequências da crise financeira internacional. Perante este cenário, algumas empresas de construção nacionais optaram pela internacionalização como estratégia para angariar trabalho e, em alguns casos, para a própria sobrevivência. Mas a entrada em mercados internacionais é uma decisão complexa que deve ser adequadamente preparada e conduzida para que leve a bons resultados e com riscos de insucesso controlados, e não se compadece com decisões voluntaristas que possam ter o efeito contrário ao pretendido. A internacionalização não é estranha a várias empresas do setor desde longa data; o que é novo é que, no passado recente, esta opção cativou novas empresas, adquiriu novas motivações, e se revestiu de novos contornos que importa analisar. O objetivo desta dissertação é elaborar um estudo que permita uma abordagem à temática da internacionalização (modelos...

Proceedings IGLC-18, July 2010, Technion, Haifa, Israel; As Lean Construction (LC) steadily grows all over the world, not much is heard about this new paradigm in the Portuguese Construction sector. Because LC has been embraced in other countries for its positive, cost-effective results, it is assumed that it can also greatly contribute to the Portuguese construction sector. This paper thus intends to analyze the ways in which LC can be beneficial in the Portuguese context. This article first seeks to identify the causes of delays and material losses in the Portuguese construction sector by analyzing three main phases in the construction process: the contract phase (CP), the planning phase (PP) and the production phase (PrP). Secondly, this work intends to assess how to improve those areas of difficulties using Lean Construction solutions and how to bring out the full potential of these solutions in the Portuguese construction context. Through these findings, this work seeks to foster the acceptance and use of Lean Construction and reveal its benefits to the Portuguese construction sector. The goal is to alert planners to the importance of ―stopping the line‖ according to LC principles, thereby stopping the small problems and wastes from becoming bigger and costly in the future.

Proceedings IGLC-19, July 2011, Lima, Perú; In times when Sustainability is a major concern in public opinions all around the planet, it has become a constant issue for most Industries. The Construction Sector is not an exception to this trend, and efforts have been reported on seeking to adopt metrics that can measure Sustainability on site. On the other hand, the concept of Lean Construction (LC) is becoming a reality more and more present in this sector. Its effectiveness in controlling and eliminating wastes are becoming more and more acknowledged. Both concepts appear to have significant principles in common, hence this paper intends to examine and establish a relationship between LC and Sustainability, and assess their complementarity. This paper portrays a case study where LC tools and techniques where applied on a construction site, in order to observe and assess the relationship and complementarity between those and the Sustainability Construction Index (SCI) developed by a major Portuguese Construction Company, Soares da Costa Construções, S.A.(SDC).

21th Annual Conference of the International Group for Lean Construction (IGLC 21), July 2013, Fortaleza, Brazil; As Lean Construction steadily grows all over the world, not much is heard about this new paradigm in Portugal, and the Portuguese construction industry still seems unaware of its potentials. This study aims at characterizing and analyzing the main causes for waste that could be tackled with Lean Construction solutions and techniques in the Portuguese construction sector. It is assumed that lean construction can greatly contribute to the Portuguese construction sector by the positive costbenefit results. An analysis is made on how lean construction can be beneficial in the Portuguese context, from the perspectives of owners and designers. The study is an exploratory qualitative research that is observational in nature. Overall, 8 private owners, 10 public owners and 13 design firms participated in this study. The results obtained are in line with similar studies and indicate that the origin of most waste in Portuguese projects has its roots in the design phase due to owners’ actions. This work seeks to demonstrate the key role that owners have in the adoptions of lean construction methods and principles, which can be implemented to mitigate the main problems found.
