“…This makes the calculation of a tender programme and price for a construction project difficult. Several aspects of the literature in construction management indicate that the quality of tender documents is often "poor" in practice (see for example, studies by Liu and Ling, 2005;Fang et al, 2002;Akintoye andFitzgerald, 2000 andSmith andBohn, 1999). However, there is little empirical research in the literature on the quality of tender documents used in construction and the practical implications of poor quality tender documents in construction.…”

Tendering is one of the stages in construction procurement that requires extensive information and documents exchange. However, tender documents are not always clear in practice. The aim of this study was to ascertain the clarity and adequacy of tender documents used in practice. Access was negotiated into two UK construction firms and the whole tender process for two projects was shadowed for six to seven weeks in each firm using an ethnographic approach. A significant amount of tender queries, amendments and addenda were recorded. This showed that quality of tender documentation is still a problem in construction despite the existence of Co‐ordinated Project Information (1987) and British Standard 1192 (1984, 1990, 2007) that are meant to help in producing clear and consistent project information. Poor quality tender documents are a source of inaccurate estimates, claims and disputes on contracts. Six recommendations are presented to help in improving the quality of tender documentation. Further research is needed into the recommendations to help improve the quality of tender documents, perhaps in conjunction with an industry‐wide investigation into the level of incorporation of CPI principles in practice.Case study, contractor, tender documentation, tendering, UK,

“…It is common practice in Malaysia and other countries that cost-related preliminary items are measured entirely in lump sum [20], [21], [39] with long-winded descriptions. Unfortunately, the breakdown of items is not mandatory, thus the components of the lump sum price are not verified.…”

Civil engineering work deals with nature and thus, is exposed to enormous discrepancies due to nature’s complexity compared to building works which are more certain. In the Malaysian construction industry, it is generally accepted that civil engineers administer civil engineering contracts and prepare tender documents. The Civil Engineering Preliminaries Protocol (CEPP) for conventional contracts is an ongoing research that deliberates on the cost-related items included in the Preliminaries. Preliminaries are subjective in nature and largely challenging to price. This paper considered previous research findings by conducting a literature review and accordingly, highlighted the problem statements raised on the contractual risks present due to the fallacy of item description. The identification of underlying problems and gaps within the area of study justifies the aim of the research to establishing a common protocol that is conversant to both engineers and contractors. The objective of the protocol is to eliminate disputes due to vagueness, ambiguities, and duplication of preliminary items in order to improve price accuracy. In practice, different approaches are taken by engineers and contractors in dealing with preliminary items. Engineers provide bills of preliminaries and contractors price them accordingly without establishing any mutual understanding and responsibility for risks. Conventional contracts prohibit contractors to provide their own preliminaries. Contractors instead have to obtain clarification on any ambiguities in the contract within the speculated time given during the tender period. As a way forward, the CEPP provides better clarity, accuracy, and transparency to engineers and contractors as well as the other construction players in general. Reliable descriptions of preliminary items ensure better price accuracy for the betterment of the construction industry.

“…The importance of recognizing risks in the cost estimation process from the aspect of multicriterion ranking of alternative solutions is a systematic approach and requires well-trained staff based on an experiential approach discussed by Ferrada et al [2] and McCaffer et al [3]. Recognizing the needed time and the available budget in order to achieve quality-based standard requirements is also a challenge for experts in this field, described by Smith [4].…”

The aim of the paper is to research and analyze the impact of the type of failure on economic risks in the bidding phase, as the most important part in the management of construction projects. The survey included the impact of risk on the process of determining unit prices from the perspective of a potential contractor. Also, the failure rate and repair rate of the 34 machines from the machine park of the company for road construction were researched. On the basis of obtained parameters and depreciation periods, the operational availability of components of construction production systems was determined. The proposed methodology for estimating impact of the availability function is a modified method of the frequency balancing. It has been tested on a concrete project from the practice in the process of harmonizing construction norms of time that preceded the final adoption of the unit prices. Differences in prices are results of the system failure of construction machinery and plants and have justified a hypothesis of obtaining more realistic costs that can occur in the projects.
