TL;DR: Cost Studies of Buildings as mentioned in this paper is a practical and easy-to-use guide to the cost management role of building construction, focusing on the importance of costs of constructing projects during different phases of the construction process.
Abstract: This practical guide to cost studies of buildings has been updated and revised throughout for the 6th edition. New developments in RICS New Rules of Measurement (NRM) are incorporated throughout the book, in addition to new material on e-business, the internet, social media, building information modelling, sustainability, building resilience and carbon estimating. This trusted and easy to use guide to the cost management role: Focuses on the importance of costs of constructing projects during the different phases of the construction process Features learning outcomes and self-assessment questions for each chapter Addresses the requirements of international readers From introductory data on the construction industry and the history of construction economics, to recommended methods for cost analysis and post-contract cost control, Cost Studies of Buildings is an ideal companion for anyone learning about cost management.

TL;DR: In this article, a wide range of strategies that can be applied during the design and construction process to add value and bring the best interests of the client sharply into focus are discussed.
Abstract: Added Value in Design and Construction takes a holistic, student-centred approach to offering public and private sector clients the ultimate reward; doing more for less. The Latham Report was a call to action and this book provides students of construction with the theoretical and practical knowledge to deliver the recommendations of the report. It describes the principles and techniques crucial to adding value and reducing costs in design and construction in the twenty first century. This book examines in detail a wide range of strategies that can be applied during the design and construction process to add value and bring the best interests of the client sharply into focus.

TL;DR: In this paper, the authors developed linear regression models to predict the construction cost of buildings, based on 286 sets of data collected in the United Kingdom, and the best regression model is the log of cost backward model which gives an R2 of 0.661 and a mean absolute percentage error (MAPE) of 19.3%.
Abstract: This paper describes the development of linear regression models to predict the construction cost of buildings, based on 286 sets of data collected in the United Kingdom. Raw cost is rejected as a suitable dependent variable and models are developed for cost∕ m2 , log of cost, and log of cost∕ m2 . Both forward and backward stepwise analyses were performed, giving a total of six models. Forty-one potential independent variables were identified. Five variables appeared in each of the six models: gross internal floor area (GIFA), function, duration, mechanical installations, and piling, suggesting that they are the key linear cost drivers in the data. The best regression model is the log of cost backward model which gives an R2 of 0.661 and a mean absolute percentage error (MAPE) of 19.3%; these results compare favorably with past research which has shown that traditional methods of cost estimation have values of MAPE typically in the order of 25%.

TL;DR: In this article, the authors explore opportunities for incorporating design quality indicator (DQI) assessments into a project management system that ensures the delivery of stakeholder value during the design stage.
Abstract: The role of stakeholders in defining project values influences product quality expectations as well as designers expectations in meeting these goals. Ultimately, these determine the functional, physical and symbolic product characteristics that are necessary to achieve customer satisfaction. The issues of value and quality are compared within the context of design management, including their theoretical and philosophical underpinnings as well as current management techniques. Value and quality can be misunderstood and confused; therefore, it is vital for stakeholders to have a common understanding of terminology and meaning. This is particularly true of customers who need to be engaged in a straightforward manner. Our research into the management of value delivery in design is used to explore opportunities for incorporating design quality indicator (DQI) assessments into a project management system that ensures the delivery of stakeholder value during the design stage. Opportunities for customization of t...
