The evaluation of maintenance tenders is a task that involves not only consideration of the prices offered, but the financial and technical expertise of the tenderers as well. The evaluations can be highly complicated and lengthy when dealing with large projects and numerous tenderers. Presents an evaluation methodology in the form of a tabular procedure to be used by the evaluators of maintenance contracts. Develops seven tables to provide quantitative values for the submitted tenders. The first five tables are designed to evaluate the technical efficiency of the tenderers, while the sixth table is designed for the final evaluation including prices. In the first table, the tender compliance as per the requirement of the tender document is evaluated. Uses the second table to evaluate the support and maintenance plan. The third table presents an evaluation of the experience and the financial status of the tenderer. The fourth and fifth tables are used to evaluate the tenderer’s staffing proposal and how it is related to the requirements of the project. The sixth table summarizes the evaluation of the previous four tables for each evaluator. The seventh table illustrates the final evaluation of each tenderer, and hence a decision could be made. By adding the average technical score of each tenderer to his price score, the evaluator can easily rate each tenderer’s ability to carry out the work rather than depending only on price, which might not always mean a good choice.

Target cost contracts are growing in popularity but concerns remain about the interplay between fee, target, sharing ratios and the final price. This paper offers a fundamental analysis of the principles under‐pinning target contracts. It shows that there is scope for manipulation of tenders and that suboptimal methods of tender evaluation are in use. The paper analyses both fixed fee and percentage fee contracts. Methods of tender evaluation are proposed that will both reduce the scope for manipulation by tenderers and increase the likelihood of the contract being awarded to the tenderer whose final price will be the lowest. The analysis reveals a strong case for setting the contractor's share of cost overrun or underrun at a value that is not less than 50%. Finally, the paper proposes two simplifications that would reduce the number of variables in target cost contracts of the future. One is for the employer to set the fee and the other requires only that a target be tendered but with the fee built into it.

During the tendering process for most major construction contracts there is the opportunity for bidders to suggest alternative innovative solutions. Clearly clients are keen to take advantage of these opportunities, and equally contractors want to use their expertise to establish competitive advantage. Both parties may very well benefit from the encouragement of such innovation and the availability of cheaper methods of construction than have been contemplated by the tendering authority. However recent developments in common law have raised doubts about the ability of owners to seek alternative tenders without placing themselves at risk of litigation. This common law has recognised the existence of the so‐called “tendering contract” or “process contract”. Since the tendering process is inherently price competitive, the application of the tendering contract concept is likely to severely inhibit the opportunity for alternative tenders. The “tendering contract” is automatically brought into being upon the timely submission of a conforming tender. This is contrary to the traditional view that an invitation to tender was considered to be no more than an invitation to treat, therefore submission of a tender creates obligations for neither party. Under the “tendering contract”, the owner becomes obliged to treat all tenderers equally and fairly. This paper is primarily based on the literature review. The aim of this paper is to highlight the problems with the competitive tendering process in relation to contractor‐led innovation and explore ways in which owners can develop procurement procedures that will allow and encourage innovation from contractors.

The tender documents, an essential data source for internet-based logistics tendering platforms, incorporate massive fine-grained data, ranging from information on tenderee, shipping location and shipping items. Automated information extraction in this area is, however, under-researched, making the extraction process a time- and effort-consuming one. For Chinese logistics tender entities, in particular, existing named entity recognition (NER) solutions are mostly unsuitable as they involve domain-specific terminologies and possess different semantic features.

To tackle this problem, a novel lattice long short-term memory (LSTM) model, combining a variant contextual feature representation and a conditional random field (CRF) layer, is proposed in this paper for identifying valuable entities from logistic tender documents. Instead of traditional word embedding, the proposed model uses the pretrained Bidirectional Encoder Representations from Transformers (BERT) model as input to augment the contextual feature representation. Subsequently, with the Lattice-LSTM model, the information of characters and words is effectively utilized to avoid error segmentation.

The proposed model is then verified by the Chinese logistic tender named entity corpus. Moreover, the results suggest that the proposed model excels in the logistics tender corpus over other mainstream NER models. The proposed model underpins the automatic extraction of logistics tender information, enabling logistic companies to perceive the ever-changing market trends and make far-sighted logistic decisions.

(1) A practical model for logistic tender NER is proposed in the manuscript. By employing and fine-tuning BERT into the downstream task with a small amount of data, the experiment results show that the model has a better performance than other existing models. This is the first study, to the best of the authors' knowledge, to extract named entities from Chinese logistic tender documents. (2) A real logistic tender corpus for practical use is constructed and a program of the model for online-processing real logistic tender documents is developed in this work. The authors believe that the model will facilitate logistic companies in converting unstructured documents to structured data and further perceive the ever-changing market trends to make far-sighted logistic decisions.

The purpose of this paper is to examine how the period for which a public procurement notice remains open for bidding (Δt) affects the number of bids.

The authors investigated data for 2.404 open procurement tenders in Greece for the years 2018–2021. Using Δt as the grouping factor, the authors defined two samples based on the European Union time limits for the receipt of tenders. Group 1 (Δt ≤ 35) contains all tenders for which the contracting authorities (CAs) have chosen to limit themselves to the minimum number of days allowed by law. Group 2 (Δt>35) includes the remaining tenders where CAs have chosen to keep their notices open for periods beyond the existing minimum time limits, as they are encouraged to do by law.

A Mann–Whitney U test, in combination with graphical analysis, revealed that CAs from Group 2 tend to enjoy more bids per tender, that is, more intense competition.

The paper allows decision-makers and legislators to understand the relationship between the time CAs choose to keep their notices open for bidding and the number of bidders in each tender, that is, competition, which according to other authors, affects the outcomes of public procurement procedures.

The paper fills the research gap regarding the relationship between time for preparation and the number of bids in each tender.

The purpose of this paper is to develop a decision model for choosing the tendering procedure in PPP that minimizes the transaction costs borne by the public sector.

A conceptual model that relates the procurement procedures described in the EU legal framework to launch PPPs and the transaction costs, considering the level of information managed by each procurement procedure has been developed. The authors use this conceptual model to develop propositions about the impact that specific project- and country-related factors have on the choice of the procurement procedure that minimizes the transaction costs.

The application of the proposed model to the case of the Italian highway “Cispadana” shows its usefulness in orienting the public authority’s choice between the different tendering procedures, taking into account project- and country-related factors.

The present study fills the gap existing in the literature on transaction costs of PPP projects and the procurement procedure used to launch those projects by developing a model that relates the level of transaction costs with a set of key factors, namely the level of information managed during the tendering process, the number of bidders, the project size, the project complexity, and the institutional environment.

As for practitioners, the main contribution of this study lies in offering a tool for supporting the public authority in the decision-making process about the tendering procedures in PPPs without imposing the selection of a specific procedure.

The approach developed provides a new tool to support the contracting authority in the design and choice of the tendering procedures in PPP.

This paper proposes an alternative method of estimating a model that predicts the outcome of a tender offer. We argue that previous econometric models designed to predict the outcome of a tender offer have been estimated incorrectly. Explanatory variables which are endogenous have been treated as though they were exogenous. Ignoring the endogeneity problem results in estimates of re‐gression coefficients which are inconsistent. In order to derive consistent estimates of the regression coefficients, we construct a simultaneous equation model to explain the outcome of a tender offer. Since two of the three dependent variables in the simultaneous equation model are dichotomous, it is necessary to use the two stage limited dependent variable estimator (2SLDV) to find consistent estimates of the regression coefficients.

Markets for public contracting are in the process of transition. Various public/private partnership arrangements replace conventional purchasing, especially within the local and regional government area. Municipal entities may not be in a position to define their needs up-front because they would not have the overview of what the market may have to offer. So one should ask: Is the traditional ban-on-negotiations in mandatory tender procedures (sealed bidding) - such as it is in EU public procurement law - counter-effective to genuine best value for public money? The article displays significant differences between European Union (EU) law, U.S. law and other regimes such as United Nations Model law, The World Trade Organisation’s Government Procurement Agreement (WTO/GPA), The International Bank for Reconstruction and Development (IBRD), and the NAFTA (North American Free Trade Agreement). New avenues for public/private demand a new agenda and the recent EU 2004 directive scheme attempts to respond to the market challenges. The author accepts that the new directive on public contracting facilitates a more smooth approach than in current EU law with regard to high-tech complicated contract awards, but questions whether the ’competitive dialogue’ really can afford tailor-made solutions to cope with long-term public/private partnership arrangements of the kind now spreading all over Europe

The provision of services by private contractors in the National Health Service rather than by direct labour is not a recent phenomenon. Certain services, eg. the erection and repair of buildings, have been performed by contractors in the majority of health authorities. In some instances, catering and domestic services have been performed by outside contractors for a number of years (although this has been the case only in a very small minority of hospitals). What is novel is a policy which says health authorities must invite companies to tender competitively against their own in‐house services, and choose the tender which is the least costly.

This paper aims to study the short-term effects of a new procurement policy document on the inclusion of environmental requirements and green award criteria in tenders. The policy document is named “Procurement with Impact” and was released by the Dutch central government to further stimulate Sustainable Public Procurement (SPP).

Central government tenders were quantitatively analyzed in the six months prior and after the release of the new policy on their inclusion of environmental concerns. This judgment was made based on the role of environmental concerns in the requirements and the award criteria. As a control group, the same was done on a municipal level, for which the new policy document does not apply. Each of the four samples contained 60 tenders. Data was acquired via the European public procurement database TED. In the analysis, a chi-square test was used to measure whether a significant difference exists between the two periods for each group.

Results show that central government has procured in a more environmentally concerned way after the release of “Procurement with Impact.” Within a year, the number of green tenders conducted by central government significantly increased from 30% to 55%. No significant difference was found on a municipal level.

SPP has received increasing attention over the past few decades but has not led to implementation of its principles in most public tenders. As SPP can have a major impact on a more sustainable and social society, it is important to understand how policy can influence the sustainability of tenders. The findings of our study show that “Procurement with impact” had a significant positive short-term effect on the inclusion of green award criteria and requirements in public tenders. Implementing similar SPP policies in other government sectors and other countries could have a substantial effect on the worldwide uptake of SPP.

“Procurement with Impact” contains a clear sustainable vision embracing the principles of SPP. This government policy takes into account several SPP barriers and drivers and satisfies several policy theory conditions. The authors show in the paper that this policy is an effective instrument for increasing the inclusion of environmental concerns in tenders. As the difference is already significant within a year, this could also reflect the readiness of tenderers to turn to SPP once there is a clear organization wide policy.
