Work Zone Illumination Design: Guidance Stratgies To Specify Appropriatework Zone Lighting Plan, Sherine Anani
Theses and Dissertations
Night construction is frequently used because it can better satisfy the primary traffic control objectives than daytime work. If night construction is used, the design of illumination plans should be analyzed and developed as part of the project development process.
There are fewer crews out working on the road in the winter, partly because of the conditions but also because the days are shorter and there’s not a lot of light by which to work.
In fact, the days can get short enough, especially as you go farther north, that even a normal day involves some “night work.” Construction work …

After direct mineral carbonation, a material rich in carbonates and with reduced quantities of free oxides is obtained. The aim of this work was to show that such materials can be used in the construction domain. Basic Oxygen Furnace (BOF) slag from the steelmaking process has been traditionally seen as unfit for bounded applications due to its propensity to swelling, resulting from hydration of its high free lime content. Here, BOF slag was crushed to suitable particle sizes, carbonated in an aqueous solution of carbonic acid, and utilized to replace 50% of natural sand aggregate in cement mortars. The mechanical …

Zero Carbon Homes: Perceptions From The Uk Construction Industry, Emma Elizabeth Heffernan, Wei Pan, Xi Liang, Pieter De Wilde
Faculty of Engineering and Information Sciences - Papers: Part A
The take-up of the many voluntary energy efficiency standards which exist in the UK and internationally has been limited. As a result, governments have recognised the need to introduce mandatory schemes through legislation, e.g. from 2016 all new build homes in the UK will be required to achieve zero carbon in regulated energy consumption. However, as 2016 approaches, very few zero carbon homes are being delivered. This paper explores the drivers and barriers for zero carbon homebuilding. The perceptions of the wider construction industry were gathered through a series of semi-structured interviews with professionals involved in commissioning, designing, constructing and …
