Abstract
Purpose
Competitive tendering in South Africa is often associated with procurement based on the lowest fee tendered. Previous research on this topic did not provide in-depth examinations of how pricing within consulting engineering companies was affected by competitive tendering nor did it illuminate the extent to which professional services were impacted by competitive tendering. This paper aims to examine the implications of competitive tendering on pricing and delivery of consulting engineering services in South Africa.
Design/methodology/approach
A survey research strategy with a questionnaire as the research instrument elicited qualitative data from 28 experienced consulting engineers in South Africa. Thematic analysis was used to analyse qualitative data from the questionnaires.
Findings
Three key themes were identified, namely: considerations when determining consulting engineering fees on competitively tendered projects; the impact of reduced fees due to competitive tendering on the delivery of consulting engineering services; and interventions to prevent unsustainably “low” professional fees. Many consulting engineers in South Africa still determine fees using fee scales, while other considerations include resources, project complexity, risk, etc. Most participants asserted that design optimisation/value engineering, training, meetings and construction monitoring were adversely impacted by “low” fees.
Originality/value
This paper provides in-depth qualitative feedback from experienced consulting engineers (most having more than 20 years’ experience) on a topical issue in the South African construction industry. Thematic analysis was a novel method of analysis that was not used previously in this area of study.

Abstract
Purpose
Skewed pricing is a typical tactic used by tenderers in unit price projects to gain additional advantages at the expense of the owner or other competing tenderers. This paper aims to describe the development of a model for detecting skewed pricing in competitive tendering for unit price contracts.
Design/methodology/approach
The model evaluates how much the offered unit rates for work items deviate from the reasonable rate identified from the item’s submitted unit rates. Item rate deviations are integrated into a total deviation score for each submitted tender based on the relative weight of the work item to the total project amount. The model allows for assigning higher weights to work items that are more prone to skewed pricing, such as those that are performed early and those that are expected to experience quantity fluctuations.
Findings
The paper presents a detection model that uses only the submitted prices of the competing tenderers to perform the needed calculations, which reduces subjectivity in identifying skewed tenders. Two examples are given to demonstrate how the model may be used to detect skewed tenders.
Originality/value
The model supports tendering officials in the challenging task of identifying skewed tenders, which is required by rules and regulations governing public procurement. The model’s ease of use is expected to make it more widely used as a decision-support tool during the tender evaluation stage of real-world projects.

Abstract
Purpose
Despite the digitalization reforms attempting to enhance public service quality, paper-based tendering is still widely used in a number of developing countries (i.e. Morocco). This has led to many issues including waste of time, higher costs as well as labor-intensive issues. E-tendering has been widely recommended as a key resolution. Still, both scholars and practitioners raised concerns related the readiness of small and medium enterprises (SMEs) to this digitalization process. The current research aims to investigate the key drivers of SMEs intention to adopt electronic tendering in the context of an emerging African market (i.e. Morocco). Specifically, the authors focus on SMEs contributing to the public procurement process and registered in the online portal recently created by the Moroccan government.
Design/methodology/approach
To achieve this goal, the authors proposed a conceptual model combining the unified theory of acceptance and use of technology (UTAUT) and technology acceptance model (TAM). Based on data collected from suppliers participating in Moroccan public tenders, the authors empirically tested the conceptual model using a partial least squares (PLS) estimation.
Findings
Facilitating conditions and social influence had a positive impact on SMEs intention to adopt electronic tendering. The study’s findings also convey a negative impact of effort expectancy on SMEs intent to adopt e-tendering. Unexpectedly, perceived performance had no significant impact on the intention to adopt electronic bidding among Moroccan SMEs.
Originality/value
This research filled the gap in the literature with regards to SMEs e-Tendering readiness in emerging markets. With the recent digitalization reforms of public tendering in many developing economies (i.e. Morocco), the study findings can be used to improve not only government implementation of electronic bidding but also SMEs' user experience.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Originality/value
(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.

Abstract
Purpose
Business-to-government corruption has destroyed many businesses and debilitated numerous countries. The paradox of plenty, or the curse of resources, is exacerbated in emerging oil and gas economies, where corruption is rampant. Corruption most frequently occurs within the tendering stage of construction projects and the current debate fails to arrest this ubiquitous boundless construct in small island developing states (SIDSs). The purpose of this study is to explain how the unique features of SIDS contributes to an understanding of B2G corruption during construction tendering.
Design/methodology/approach
This study elucidates corruption in the tendering process through the lens of collective action and principal–agent theories. Interviews with three experts and a questionnaire survey with 115 practitioners evaluated corruption in Trinidad’s construction industry. Principal component analysis reduced 33 corruption variables to 5 primary causes. In addition, the relative importance of potential solutions for curtailing corruption was assessed.
Findings
The derived factors highlight that governance within SID oil and gas economies, inadequate tender procedures and practices, reprehensible business growth strategies, unethical misconduct and the social networking context characterise public infrastructure tendering. The recommendations for minimising corruption in tendering are grounded in behaviour and deterrence theories and infused with technological advances.
Research limitations/implications
Using surveys and interviews circumvents the limitation of the inability to measure corruption because of the confines of respondents’ recall triggers. However, corruption is mediated by cultural norms, which limits the generalisation of the findings.
Originality/value
The study concludes that corruption results from a lack of transparency in the construction supply chain. It leads to an awareness gap between project stakeholders, which is a major risk factor and source of mistrust. The result is a lack of traceable processes and coordination among stakeholders. Consequently, the study fills the gap in responsible socio-economic consumption in SIDSs.

Abstract
Purpose
Pre-construction of a project comprises stages that are pivotal for the procurement performance. It is defined as the duration from the project's initiation to construction. However, Private Public Partnerships (PPPs) have been subjected to a long pre-construction, thereby leading to an inefficient development process. Therefore, the purpose of this paper is to pay attention to the influencing factors elongating the pre-construction duration.
Design/methodology/approach
Based on data of 5,677 PPP projects between 2009 and 2021 in China, the authors adopt the Accelerated Failure Time (AFT) model in duration analysis to empirically analyze the following underlying dynamics determining the duration of PPP pre-construction stages: (1) policy uncertainty; (2) corruption; and (3) procurement method selection. To observe the influencing paths more specifically, the authors divided the pre-construction duration into the pre-tendering period and tendering period and regressed them separately.
Findings
The results indicate that the pre-construction duration is significantly prolonged with increased policy uncertainty and corruption degree as well as the use of tendering methods. Meanwhile, the above factors have a greater impact on the pre-tendering period than the tendering period.
Originality/value
The contribution of this study is twofold: (1) theoretically, this paper provides new evidence on the impact of PPP policy uncertainty, corruption and procurement method selection on the pre-construction duration. It complements empirical studies on the factors elongating the time efficiency of PPPs projects. (2) In practice, it provides a specific path for the government to improve the time efficiency of PPPs.

Abstract
Purpose
Complying with the code of conduct by professionals in the construction industry worldwide has become a significant issue over the years. This has led to projects' failure, leading to losses to both the client and contractors. The study's objective is to identify the challenges of construction professionals in complying with their code of conduct and preventing corrupt practices.
Design/methodology/approach
Quantitative approach was used to collect empirical data by sending questionnaires to 56 construction professionals in South Africa. Data gathered were analysed through Excel statistical tool. Mean values were calculated for the quantitative data, whilst thematic content analyses were used to generate frequencies and percentages for qualitative data.
Findings
The findings indicate that construction professionals experience many unethical issues in their work duties such as inflated tender prices, overpricing the rates, tender-based kickbacks, bribes for projects, unethical methods of project execution, use of lower grade materials than specified, discrimination, among others. However, issues such as greediness, acceptance of corruption as usual practice, lack of knowledge about the code of conduct, the only way to get contracts, part of the process, and peer pressure create a challenge in complying with the code of conduct and preventing corrupt practices among construction professionals.
Practical implications
Construction professionals face many unethical and corrupt practices in their project management and execution, which they cannot overcome due to many factors. Therefore, there is the need to sensitise the professionals in the construction industry regarding their code of conduct as well as the danger associated with engaging in corrupt practices in their work and their implication on project performance.
Originality/value
The findings give an insight into the critical factors curtailing the construction professional's ability to comply with their code of conduct and be corrupt-free in their line of duty. Thus, professional associations can use the findings in guiding their members.

Abstract
Purpose
Efficient and effective knowledge transfer is important in complex building renovation projects. The addition of sustainability requirements in building renovation adds complexity. This paper aims to investigate the development of innovative public procurement schemes to support sustainable building renovation projects. These blueprints for procurement innovation can support similar efforts in other countries.
Design/methodology/approach
This study is based on a longitudinal case study using interviews with primary stakeholders and workshops with industry practitioners to supplement the analysis of public tender documents from the Danish public building clients.
Findings
The key tenants of the Danish model for strategic partnerships are a single strategic partner, systematic conflict resolution, framework agreements, risk management and joint educational programs. Three phases in the development of the procurement scheme are identified: experiment, definition and replication.
Originality/value
Strategic partnerships and other types of relational contract schemes are not very prevalent in most countries. How these contracts are developed and defined is not well understood. This paper shows how one such contracting scheme is developed, how it is defined and replicated.

Abstract
Purpose
Insufficient time allocation for the bidding period occurs, causing drawbacks to both parties, the client and the bidder. Hence, this study aims to evaluate the time allocated for preparing a bid proposal as per the National Competitive Bidding (NCB) in the Sri Lankan context.
Design/methodology/approach
The study has adopted a mixed method approach and expert interviews and document review to detect, analyse and validate the issues, and solutions based on NCB along with the adequacy of the allocated bidding period used as main data collection tools. Both qualitative and quantitative data were analysed through manual content analysis and inferential analysis respectively.
Findings
Overall, 24 local issues with the existing competitive bidding process and solutions for each were identified. Among the 24 local issues, it was unanimously agreed by all interviewees that three specific issues require attention and improvement. These issues are related to the standard and incompleteness of bidding documents, inaccurate BOQ quantities measured by the consultant or the main contractor, and the excessive number of bidding document amendments by the consultant. It was revealed that a maximum of 42 calendar days (6 weeks) is sufficient for the bidding process while a minimum of 21 calendar days (3 weeks) is insufficient.
Originality/value
The findings of this study would be recommended that Information and Communication Technology Agency (ICTA) understand the necessity of revising the NCB reference to the time allocated for the preparation of bids. By recognising the importance of sufficient time allocation for bid preparation, this research serves as a practical guide for authorities involved in policy formulation, aiding them in implementing revisions that align with the dynamic requirements of bidding procedures.
