An integrated life cycle costing database: a conceptual framework

Life cycle costing (LCC) is a management technique that has been available to the industry for some time, but despite this it continues to languish in obscurity. Some clients, most apparently from the public sector, are fostering the technique by commissioning studies based on the LCC appraisal techniques. However, the majority of building designs are still currently produced unsullied by thoughts of maintenance implications, life expectancy or energy consumption. Recent technological developments, particularly in Web, Virtual Reality (VR), and Object Oriented technologies and mathematical and computational modelling techniques will undoubtedly help in resolving some of the problems associated with life cycle costing techniques. This paper outlines a conceptual framework for an innovative system that facilitates the implementation of LCC in various design and occupancy stages. This system is being developed within an EPSRC-funded research project, undertaken through a joint collaboration between the Robert Gordon University and the University of Salford

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Whole-life costing in construction: A state of the art review

This report is a state of the art review of whole life costing in the construction industry. It is the first of a series reporting on-going research undertaken within the research project Developing An Integrated Database For Whole Life Costing Applications In Construction. This project is funded by the EPSRC and undertaken by a unique collaboration between two teams of researchers from the Robert Gordon University and the University of Salford. The fundamental basics of whole life costing (WLC) are introduced. First, the historical development of the technique is highlighted. Then, the suitability of various WLC approaches and techniques are critically reviewed with emphasis on their suitability for application within the framework of the construction industry. This is followed by a review of WLC mathematical models in the literature. Data requirements for WLC are then discussed. This includes a review of various economic, physical, and quality variables necessary for an effective WLC analysis of construction assets. Data sources within the industry are also highlighted with emphasis on current data collection and recording systems. In addition, the requirements of a data compilation procedure for WLC are outlined. The necessity of including the analysis of uncertainty into WLC studies is discussed. Attempts to utilise various risk assessment techniques to add to the quality of WLC decision-making are reviewed with emphasis on their suitability to be implemented in an integrated environment. Essential requirements for the effective application of WLC in the industry are outlined with emphasis on the design of the cost break down structure and the information management throughout various life cycle phases. Then, directions for further future research are introduced

Automating progress measurement of construction projects

The accurate and up to date measurement of work in progress on construction sites is vital for project management functions like schedule and cost control. Currently, it takes place using traditional building surveying techniques and visual inspections. The usually monthly measurements are error prone and not frequent enough for reliable and effective project controls. This paper explores the potential of using computer vision technology in assisting the project management task. In particular, it examines the development of an integrated building information system that aims to determine the progress of construction from digital images captured on site in order to semi-automate the work in progress measurement and calculation of interim payments as well as function as an early warning system of potential delays. The study focuses on the quantity rather than quality aspect of work and is limited to the superstructure of buildings
