- W2273171413 abstract "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. from several fields of expertise whose primary bond, would be to contribute towards a more transparent, efficient, qualification-driven, credible market unhindered by bureaucracy. 1.2 Goals and aims of the present study The aim of this study is to draw attention to prior research into the reasons and consequences of this specific problem. Then, taking cues from the extant research and the opinions/suggestions gleaned from several parties to the process on the lack of competitiveness in the Portuguese construction industry in the research project the author of the present study is currently working on, will be point out some preventative measures that would lessen the impact of the problems discussed. 2 DIAGNOSTIC OF PROJECT DESIGN ERRORS (ROOTS) 2.1 What previous literature says The way projects are prepared often leads to systematic repetition of previous construction mistakes, which impacts costs, causes extra work and time overruns and frequently calls for design changes. One of the areas which tends to cause more problems is the adaptation of the foundations and structure of the building to the terrain itself, due to the lack of valid data at the design stage. Constructive elements that touch the divide between businesses do cause some of the deviations verified. Owners display little care in the preparation of the elements they supply to project designers. These are prepared by a number of independent specialists who in turn hire their own surveyors with little thought given to coordination. That is why incompatibility and deficiency issues arise. Among more frequent causes for lack of quality in design projects conceived for bidding and building purposes, we would point out the following (Santo 2002): − A lack of up-to-date topographical surveys and geotechnical studies that would describe on-site conditions so as to allow for an appropriate design of foundations and structures, evaluation of soil processes and outside work − Little coordination among differing projects with an integrated vision, so as to make compatible the work assigned to different specialty teams, extending the scope of work to the surroundings, namely landscaping and connecting with infrastructures − Lack of accuracy in defining work schedules, especially with measurement maps, surface works lists contract provisions and construction details, finish maps and designed pieces − Non-existence of an on-site quality control system that would allow for the identification of mistakes, evaluate their consequences and generate guidelines to help in future projects. Some of the errors listed above stem from the structural model of many architect and engineer teams which more often than not are small-scale businesses and must subcontract with specialists. In each project there must be different architectural specialists, engineers, designers, surveyors and budget specialists. These professionals do not, as a rule, hold coordination meetings. Nothing but incompatibility and on-site lack of accuracy can follow, as is later detected." @default.
