Computer Aided Call for Tenders: A Tool for Software Bidding

Under a broad comprehension of Software Engineering, it is preferred the term software life cycle instead of just software production. The reason is that cycle starts at software conception and stops when the software is relegated. Given contemporary companies’ market strategies of focusing on their competitive advantages, most of them have externalized their software production to outsourced services. Therefore, the call for software tenders has become a common step in the software life cycle. In this paper, we present a tool which aids non-experts to specify call for software tenders. The motivation was Chile situation of most of rural and semi-urban city halls which do not have engineering teams to build call for software tenders. We describe the problem in terms of lack of competitiveness and empty biddings generated by low quality calls for tenders. As a second step, we show the technical considerations to develop the proposed tool and its features. We include an initial tool perception from a first group of users.

Impact of Prevailing Wages on the Cost among the Various Construction Trades

In 1997, the Ohio Senate passed Senate Bill 102 which established the Ohio School Facilities Commission as a separate agency to oversee the rebuilding projects of the public schools in Ohio. The bill also exempted the construction contractors from paying prevailing wages on these projects on the hypothesis that this exemption would lower the construction cost. The purpose of this study is to investigate this hypothesis through the statistical analysis of 8,093 bids received from the years 2000 through 2007 for the schools＇ construction. Union contractors who paid their workers union wages and non-union contractors who did not pay prevailing wages bid these projects. The hypothesis, that prevailing wage laws increased the construction cost, was tested by comparing the bids/SF （square foot） from both groups （union and nonunion） for the different construction trades. The study indicated that there was statistical significant difference between the bids/square foot for union contractors and the bids/square foot for non-union contractors for only the following trades： earthwork, existing conditions, plumbing, electrical and HVAC （heating, ventilation and air conditioning）. The averages of bids/SF from the union contractors were higher than those from the non-union contractors for earthwork, existing conditions and plumbing works, and the opposite for electrical and HVAC works. There was no statistical significant difference in the bids from the communications, concrete, conveying equipment, electronic safety and security, equipment, finishes, fire suppression, furnishings, masonry, openings, structural steel, thermal and moisture protection, plastics and composites and wood works.

A Bidding Model for Construction Price Preparation

Estimation of the price of a contract project is an important task of the construction bidding price. The quality of construction management depends on accurate estimation. This paper presents a bidding model for construction bidding price preparation in a competitive bidding environment. The bidding price for a new project is prepared by using a library of data containing rate, quality and data for the elements of previous completed projects. The data of previous completed projects is used to prepare the bidding price of a new project. Three bivariate treatments are used to model the data of rate vs quality.

Detection Tool for Unbalanced Bids

Unbalanced bidding is a cash flow management strategy that is recognized as an illegal/disqualifying practice by public owners;and unethical practice by most private owners. This practice provides the awarded bidder with unjustified advantages at the expense of the owner. Unfortunately, limited tools and techniques are currently available to identify and detect unbalanced bids during the evaluation process. This paper presents an innovative detection tool to identify unbalanced bids in unit price contracts during the bid evaluation process. The proposed technique develops BMDI graphs to visualize total markup variation patterns during the project lifetime to detect unbalanced bids. The proposed method also uses Monte Carlo simulation to take in consideration the impact of cost uncertainties and risks. An illustrative example was presented to show the capabilities and features of the proposed method in determining the status of submitted bids during the evaluation process.

E-Tendering Process Within Construction:A UK Perspective

E-tendering can be defined as the issue and receipt of tender documentation through electronic means which facilitates the procurement of construction work and the award of contracts. The current paper-based method of tendering has been commonplace within the industry for a significant number of years, but with recent technological advancements, this traditional process is rapidly becoming outdated. Several major projects within the UK are now being procured through the e-tendering process which includes the multibillion pound development for the Olympic Games in London 2012. However, while these prestigious projects are embracing e-tendering technology, it is not certain as to what extent e-tendering is used across the construction sector generally. This research is primarily concerned with establishing the current status, practicalities and resource effectiveness of e-tendering within UK construction. Results are provided from an in-dustry survey which includes both quantitative and qualitative data. A case study implementation is also in-cluded which assesses the utilisation of e-tendering software in practice. The research findings indicated that e-tendering can provide substantial resource savings to a major part of the supply chain, with the key benefits being enhanced communication, time savings and reduced costs. However, a considerable proportion of the industry remains uncertain about embracing new technologies, with reluctance to change being perceived as the greatest barrier. The findings suggest that many professionals within the UK construction industry recognise a requirement for increased implementation of e-tendering, but feel that training, education and support from senior management are essential requirements for e-tendering to become widely accepted in the future.

阴阳合同与合同变更的区分及适用——以《民法典合同编通则解释》第14条为中心

阴阳合同是当事人以虚假意思表示隐藏真实意思表示的行为,应依据《民法典》第146条分别认定阳合同与阴合同的效力。《招标投标法》第46条第1款第二句旨在限制当事人对中标合同的变更,其适用以中标合同有效为前提。因此,为落实该规定而制定的司法解释也应仅适用于合同变更,而非阴阳合同。在阴阳合同的场合,阳合同因不是当事人真实意思表示而无效,但阴合同则应依据所规避的法律来认定其效力。当事人通过合同变更规避招投标程序,应认为当事人对实质性内容的变更无效,但客观原因引起的合同变更除外;在判断是否为实质性内容的变更时,也要注意量变和质变的辩证关系。《民法典合同编通则解释》第14条在区分阴阳合同和合同变更的基础上,就二者的法律适用问题作出了明确规定。
