AbstractOne of the contract awarding systems in public sector in Poland is the Design & Build system. In this system, a client concludes a contract agreement with only one company, a contractor, in order to carry out both design and construction of works. While deciding on this form of delivery of a public project, the client is obliged to conduct a single proceeding aiming to select the contractor. In this paper, public works contracts awarded in the D&B system in Poland are analysed, whilst attention was put on the contracting modes and assessment criteria. The results are assessed against the experience of other countries and recommended methods for selection of the Design and Build contractor.

O principal escopo desta pesquisa se concentra em investigar algumas das práticas viciosas mais comuns durante a realização de processos licitatórios no setor público brasileiro. A pesquisa foi desenvolvida na metodologia exploratória, sendo aplicada a partir de casos práticos examinados por um dos órgãos de fiscalização e controle da verba pública brasileira. Foram estudados 70 (setenta) relatórios da Controladoria-Geral da União, os quais estão disponíveis na página eletrônica do referido órgão. A seleção dos casos práticos se deu aleatoriamente, sem comparar localização, perfil político e grau de repetitividade. O que se buscou foi apresentar o que é considerado bastante “grosseiro” do ponto de vista de erros administrativos. Preliminarmente, o estudo trata de aspectos gerais da licitação pública, abordando os princípios setoriais deste microssistema jurídico e as diferentes modalidades estabelecidas pelo ordenamento. Na sequência, adentrando na proposta central deste trabalho, foram examinados alguns casos práticos constatados a partir de fiscalizações em atividades de execução de obras públicas em diversos períodos e locais do Brasil. O instrumento utilizado na sondagem foram os registros oficiais dos órgãos públicos de controle, bem como, seus documentos disponíveis em suas páginas eletrônicas. A título de conclusão foi possível verificar inúmeras lacunas no tocante a organização destes procedimentos, causa principal do não cumprimento da legislação especializada. VICIOUS BIDDING PRACTICES: ANALYSIS OF CASES INVESTIGATED BY THE BRAZILIAN OFFICE OF THE COMPTROLLER GENERAL (CGU) ABSTRACT The main scope of this research focuses on investigating some of the most common vicious practices during bidding processes in the Brazilian public sector. The research was developed in the exploratory methodology, being applied from practical cases examined by one of the organs of fiscalization and control of the Brazilian public money. We studied seventy (70) of the Comptroller General's reports, which are available on the website of this public agency. The selection of practical cases occurred randomly, without comparing location, political profile and degree of repetitiveness. What was sought was to present what is considered quite "huge" from the point of view of administrative errors. Preliminarily, the study deals with general aspects of public bidding, addressing the sectoral principles of this legal micro-system and the different modalities established by the ordinance. Following, in the central proposal of this work, we examined some practical cases verified from inspections in activities of execution of public works in diverse periods and places of Brazil. The instrument used in the survey were the official records of the public control bodies, as well as their documents available on their electronic pages. As a conclusion, it was possible to identify a number of shortcomings in the organization of these procedures, the main cause of non-compliance with the specialized legislation.

Can reading great literature, considering its heroes and small characters, improve the performance of public sector actors? King Lear’s characters fault a wickedly disinterested heaven for life’s setbacks and woes. Yet Shakespeare makes clear that these actors’ own terrible choices beset the king, his family and the rest of us who are subject to the acts of public leaders. Reading this literature as analogy for the effectiveness of the modern public sector suggests how administrative operation of our democratic state may – or may not – successfully parcel power and control so as to limit negative externalities derived from ill-informed, self-serving or rent-seeking executive and individual decisions. Lear’s tragic arc mimics a sorrowful “muddling through” and potentially unnecessary “satisficing” in certain large public works projects. One large public project currently deemed successful is examined here – the replacement of the eastern span of the Bay Bridge in San Francisco – as a reflection on separated powers, the limits of human nature, and the inevitability of error.

Contractors are the main players in construction industry. Appropriate selection of contractor is crucial in determining the future performance of a project in any case. Sometimes this selection procedure is performed without proper consideration and deliberate methodology that it merits, thus bringing negative outcomes. This paper proposes a performance-based contractor selection approach that will empower the utilization of expert’s experience and data. A flexible performance-based contractor selection system is proposed to bolster this decision-making process. To characterize and design the system, semi structured interviews and questionnaire surveys were led within public sector concentrating on the way that the selection process is carried out in practice and the evaluation connected with it. A prototype of a Flexible Performance-Based Contractor Selection System (FPCSS) was developed by using Analytical Hierarchy Process (AHP) method. The system is validated by construction industry professionals in public sector. As a conclusion, the FPCSS is a significant tool for contractor selection, by helping organizations to select a competent contractor and decrease the subjectivity of the decision-making process. The advantage as gave by the system favours a reliable indicator to predict performance of construction project by selecting a contractor based on his best performan

The design-build (DB) system has been demonstrated as an effective delivery method and has gained popularity worldwide. However it is observed that a number of operational variations of DB system have emerged since the last decade to cater for different client's requirements. After the client decides to procure his project through the DB system, he still has to choose an appropriate configuration to deliver their projects optimally. However, there is little research on the selection of DB operational variations. One of the main reasons for this is the lack of evaluation criteria for determining the appropriateness of each operational variation. To obtain such criteria, a three-round Delphi survey has been conducted with 20 construction experts in the People's Republic of China (PRC). Seven top selection criteria were identified. These are: (1) availability of competent design-builders; (2) client's capabilities; (3) project complexity; (4) client's control of project; (5) early commencement & short duration; (6) reduced responsibility or involvement; and (7) clearly defined end user's requirements. These selection criteria were found to have a statistically significant agreement. These findings may furnish various stakeholders, DB clients in particular, with better insight to understand and compare the different operational variations of the DB system. Santrauka Įrodyta, kad projektavimo ir statybos (P ir S) sistema – veiksmingas vykdymo metodas, tad ji išpopuliarėjo visame pasaulyje. Tačiau pastebėta, kad per pastarąjį dešimtmetį atsirado ne vienas darbinis P ir S sistemos variantas, tenkinantis skirtingus kliento poreikius. Klientui nutarus projekto paslaugas pirkti naudojant P ir S sistemą, jam vis tiek tenka pačiam pasirinkti tinkamą derinį, idant projektas vyktų optimaliai. Tačiau darbinių P ir S variantų pasirinkimas beveik nebuvo tyrinėtas. Viena pagrindinių priežasčių – trūksta vertinimo kriterijų, kurie leistų nustatyti kiekvieno darbinio varianto tinkamumą. Siekiant nustatyti tokius kriterijus, atliekant Delphi apklausą trimis etapais buvo apklausta 20 statybos ekspertų iš Kinijos Liaudies Respublikos (KLR). Nustatyti septyni svarbiausi atrankos kriterijai: 1) kompetentingų projektuotojų statytojų pasiūla; 2) kliento pajėgumai; 3) projekto sudėtingumas; 4) kiek klientas kontroliuoja projektą; 5) ankstyva pradžia ir nedidelė trukmė; 6) mažesnė atsakomybė arba dalyvavimas; 7) aiškiai nusakyti galutinio kliento reikalavimai. Nustatyta, kad susitarimas dėl šių atrankos kriterijų yra statistiškai reikšmingas. Įvairioms suinteresuotosioms grupėms, o ypač P ir S klientams, šios išvados gali padėti geriau suprasti įvairius darbinius P ir S sistemos variantus ir juos palyginti.

This paper deals with the design of an optimal cable-driven parallel robot (CDPR) for upper limb rehabilitation. The robot’s prescribed workspace is identified with the help of an occupational therapist based on three selected daily life activities, which are tracked using a Qualisys motion capture system. A preliminary architecture of the robot is proposed based on the analysis of the tracked trajectories of all the activities. A multi-objective optimization process using the genetic algorithm method is then performed, where the cable tensions and the robot size are selected as the objective functions to be minimized. The cables tensions are bounded between two limits, where the lower limit ensures a positive tension in the cables at all times and the upper limit represents the maximum torque of the motor. A sensitivity analysis is then performed using the Monte Carlo method to yield the optimal design selected out of the non-dominated solutions, forming the obtained Pareto front. The robot with the highest robustness toward the disturbances is identified, and its dexterity and elastic stiffness are calculated to investigate its performance.

The nearly Zero Energy building (nZEB) renovation market is currently the key feature in the construction sector. RenoZEB aims to develop a systematic approach for retrofitting by assembling different technologies in a plug and play building envelope. This paper presents the methodology used to transform the RenoZEB concept in the design system. A multi-criteria decision matrix is used for the selection of the best façade technologies within the market while the analysis of the existing building conditions allows to develop a replicable approach for designing deep retrofitting intervention through a plug&play façade. The methodology appears to be a valuable support for the selection of technologies and allows to define a design guideline for the envelope.

Outsourcing has become one of the most powerful, organisation-shaping management tools available today. However, the UN’s experience in outsourcing is limited to providing troops for peacekeeping operations.  The purpose of the paper is to develop an outsourcing scorecard for the UN and similar organisations.  Forty national and international organisations were surveyed through questionnaires, review of relevant literatures and records. The research established that by identifying core competencies, goals and objectives, risks, selection of provider as well as measurements and evaluation of providers performance using an outsourcing scorecard, support functions can be outsourced successfully. Other criteria indicated as important is peace-building, suitable for humanitarian organisations. The scorecard developed by the research could provide the UN with a number of benefits, such as maximization of efficiency and savings in costs.  The paper develops the first outsourcing scorecard to guide the UN and similar organisations in identifying services that can be outsourced successfully.
