This book ... adds to the impressive 'legacy' of learning which is still emerging from the successful delivery of the London 2012 construction programme. The authors combine the reforming zeal of a champion for change, who was there every step of the way, with academic rigour, and the result is delivered with impressive passion and commitment to the topic ... All spenders and suppliers need to read this, to understand how conventional understandings of procurement fall so dramatically short when applied to high value-high risk acquisitions, which invariably is what large construction projects represent.'                                           Don Ward, Chief Executive, Constructing Excellence, UK Successful construction is often attributed to one or more aspects of the delivery process from good planning, design and clever engineering to efficient project management and quality construction. Before any of these disciplines can begin, they all require some form of procurement to select the team or supply chain to meet a client's or a project's specific requirements. The concept of PSE - Purchase and Supplier Engineering - originated in the procurement of the construction and infrastructure required to stage the 30th Olympiad in London during 2012.  At the time of writing PSE has successfully delivered almost £25bn of public procurement meeting client and project requirements and without legal challenge. The construction of the venues and infrastructure needed to stage London 2012 was such a resounding success that it boosted not only the reputation of the UK construction industry but also the confidence of the UK population in the country's ability to organise, build and run a major international event. Its success has been lauded as something from which clients and industry could learn. The ODA has established a comprehensive and informative body of evidence as part of a Learning Legacy. While the ODA is well aware of the many elements of the procurement and supply chain management, the complete end to end concept of how the Olympic supply chain procurements were managed has until now not been captured.  For example, how does one buy the stage for an Olympic Games? How does one manage the details of thousands of contracts and the many firms of contractors, subcontractors and material suppliers and ensure that no one organisation adversely affects any other to the detriment of the programme?  How are a client's requirements beyond those of the capital asset realised as part of the investment? How does one measure programme exposure, or manage performance?  How does one measure capacity and the ability of firms to cope with the work and manage the risks involved?  Programme Procurement in Construction: Learning from London 2012 covers the planning and preparation of a programme's procurement processes from understanding and developing the client's requirements, to monitoring performance based on the benchmarks contractors set out in their own tender submissions. The emphasis is on a close attention to detail to avoid surprises, while keeping a focus on the total programme.  Purchase and Supplier Engineering provides an overview of managing the interest of firms in participating and the resulting capacity and workloads of all suppliers, including the main contractors and the critical subcontractors and material suppliers.  Offering techniques, tips and lessons learnt from the implementation of PSE on London 2012 and Crossrail, this book is aimed at public and private sector clients, developers, senior management and those businesses and professionals involved in undertaking the procurement, supply chain management and delivery of multiple construction projects or complex major construction programmes.  

Blockchain technology has been recognized as one of the emerging technologies that can significantly innovate many industries. Major advantages of using blockchain technology includes reducing transaction costs, preventing data forgery and alteration, and further flexibility. The construction industry is generally considered as an industry that has great potentials for blockchain technology utilization mainly due to the high volume of transactions among various entities. Despite the perceived positive impact, there have been few cases of blockchain applications within the construction industry. This study is conducted with an aim of finding ways to apply blockchain technology to the construction industry. In order to identify potential application areas, construction lifecycle and project management knowledge areas are used in developing a survey questionnaire. Data collected from the survey is analyzed by employing importance performance analysis (IPA) method considering both applicability of the technology and anticipated impact from utilizing the technology. In relation to the construction project lifecycle, ‘Project Cost/Change Management’, ‘Contract Bidding and Formation’, and ‘Procurement Evaluation’ are emerged as top three candidates for blockchain application with high applicability and impact. Regarding the knowledge area, ‘Procurement Management’ and ‘Cost Management’ are identified as the main blockchain application areas with high applicability and impact. All the identified specific construction tasks with high applicability and impact are related to ‘Procurement’, ‘Contract’, and ‘Cost’. Therefore, it is reasonable to start focusing blockchain convergence efforts these areas and then expand them as the technology matures.

This is a practical guide to the operation and administration of JCTs IC16 suite of building contracts including both IC and ICD. All of the contracts provisions, procedures and conditions are organised and explained by subject, clearly distinguishing the different obligations due to various parties and the contractual issues arising during the course of a job - all backed up by the latest legislation and case law.

The unstable economic conditions that have been in place in the Slovenian and international construction markets reveal the problem of a disproportionate increase in the prices of construction materials and energy products. Such increases will therefore result in higher costs of construction services, which would ultimately affect the total value of the construction project. These events in turn bring uncertainty to the construction project and would negatively impact the business of construction companies and investors. Legal and construction practices have so far developed various ways to regulate contract changes arising due to unforeseen market conditions. The present paper offers a contribution to the contract price change solution during the construction phase. The introduction first presents the measures and guidelines that deal with the differences in contract prices in Slovenia and some other countries. Then, various methods of calculating price differences that have emerged in current Slovenian practice are described. As a result, a proposal for a hybrid method of monthly price difference calculation is presented. The hybrid method represents a balanced solution resulting from the unforeseen increase in construction material prices on the market and is applicable to all construction projects. The three methods, i.e., a calculation method, a method based on the GZS-ZGIGM index, and a hybrid method, are applied to a real example of a public contract. The calculation of the price valorisation, represented as an index of the recognised price increases of contract works, is carried out. The results are compared, and further solutions are proposed.

Sarah Lupton's best-selling guide, fully revised for JCT 2016, provides the most up-to-date authoritative working aids to the operation and administration of the main JCT Standard Building Contract 2016.

PurposeConflicts, claims and disputes are inherent in most construction projects. Acceptable degree of commonality in the interpretation of contract provisions is critical in effective contract administration. This study aims to assess the effects of contract ambiguity factors on construction conflicts, highlighting the causes of divergent interpretations using fuzzy technique for order of preference by the similarity-to-ideal-solution (TOPSIS) method.Design/methodology/approachFuzzy TOPSIS framework with 27 ambiguity factors is constructed by conducting a comprehensive literature review, accompanied by a pilot study. Questionnaire survey is formed, and one-to-one interviews are arranged with 35 contract administration experts.FindingsThe findings indicate that (1) ambiguity due to excessive changes in the bill of quantity (BOQ) (including ambiguous provisions related to BOQ changes), (2) incomplete clauses that do not describe the scope of the intended work purely, (3) ambiguity due to excessive amendments in the scope of works (including ambiguous provisions related to scope changes), (4) ambiguous enforceability including excessive demands and (5) ambiguous goal and performance requirements are the top five ambiguity factors affecting construction conflicts.Research limitations/implicationsPresented framework is performed referring to ambiguity factors in all type of construction contracts in the general sense. However, the identified factors may vary depending on the project type, contract type, procurement method or use of standard contract forms (such as NEC, FIDIC).Originality/valueThe literature lacks the investigation of ambiguity factors in construction contracts, yet the assessment of the effects of contract ambiguity is essential to minimize conflicts.

Disputes are common in the intricate professional setting of the construction sector. When claims cannot be resolved kindly, they often escalate into conflicts that result in litigation. Identifying the root reasons of these claims and understanding their effects on project timelines, costs, and quality can help prevent poor performance in construction contracts. This study makes a unique contribution by developing a cause of claims breakdown structure (CCBS) that systematically categorizes the most frequent roots of claims identified in the building sector through an extensive literature review, and by subsequently assessing these categories using expert-based relative importance indices (RII). Using relative importance indices derived from specialist opinions, the research provides likelihood and influence quantities for 15 typical claim sources in the building sector. These values offer stakeholders in public construction projects a framework for assessing risks and planning mitigation strategies for construction claims. The study reveals the five most significant risk factors for contractual claims in the Kuwait building sector. These issues are ambiguities in contract language, followed by weather-related disruptions, ineffective communication among stakeholders, inadequate planning, and regulatory changes.
