This manual provides guidance for engineers on construction sites and lists references from which to obtain further and supporting information. It is a daunting challenge to adequately advise and steer site engineers for the wide range of construction projects on which they might be employed. David Doran with his fellow authors successfully advises from earthworks and foundations through structures to cladding, services and finishes. Management, quality, health and safety, plant, setting out and weather are dealt with separately. At 452 pages it still lists over 500 British Standards and other documents for further information. Many of those will in turn refer to more documents. How do engineers get the time to become reasonably familiar with those they are deemed to know and the application of them to problems arising on site? Many Codes do not contain advice for those dealing with temporary works and other site activities. A notable exception is BS 5975 for falsework and chapter 11 draws particular attention to this and a few more of its references but other chapters are not so helpful.
Construction is undertaken by a workforce under the direction of foremen and charge-hands. The task of the site engineer is to enable them to operate efficiently and accurately. The site engineer needs to work closely with them to provide setting out which enables the work to be constructed and controlled easily with checks made at appropriate stages when any adjustments can be made with minimal delay and cost. The workforce and supervisors need to have confidence in their site engineer and the instructions provided not least because his actions can affect their productivity and bonus. With confidence in him/her they are more likely to be forthcoming with practical suggestions. More could have been included about working and communicating with people on site but then what does one leave out!
The codes, standards, guides and regulations applying to construction seem to be constantly increasing and changing and engineers keep abreast of them with difficulty. Manuals such as this one are much needed and this one is commended for site engineers.

EN 1917:2002 Concrete manholes and inspection chambers, unreinforced, steel fibre and reinforced + AC:2006
This European Standard specifies performance requirements as defined in table 1 and describes test methods for precast concrete units, including joints (elastomeric, plastomeric or other sealing materials, either integrated in the unit or supplied separately), for inspection chambers designed to be used for inverts not exceeding 2 metres deep and manholes, of circular, rectangular (with or without chamfered or rounded corners) or elliptical internal shape, unreinforced, steel fibre and reinforced, with nominal sizes not exceeding DN 1250 for units with a circular bore or LN 1250 for units with a rectangular or elliptical shape.
BS 5911-3:2010 Concrete pipes and ancillary concrete products Part 3: Specification for nreinforced and reinforced concrete manholes and soakaways (complementary to BS EN 1917:2002)
BS EN 1917 specifies requirements and describes test methods for precast concrete manholes of circular, rectangular (with or without chamfered or rounded corners) or elliptical cross-section, unreinforced, steel fibre and reinforced, with nominal sizes or nominal lengths not exceeding DN 1250 or LN 1250, respectively. The intended use of BS EN 1917 is to permit access to, and to allow aeration of, drain or sewer systems for the conveyance of sewage, rainwater and surface water under gravity or occasionally at low head of pressure, mainly installed in areas subjected to vehicular and/or pedestrian traffic.
This part of BS 5911 specifies complementary requirements to those in BS EN 1917 for unreinforced and reinforced concrete manholes of circular and rectangular cross-section (with or without chamfered or rounded corners), as provided for in BS EN 1917, i.e. units with nominal sizes or nominal lengths not exceeding DN 1250 or LN 1250, respectively. Full requirements for unreinforced and reinforced concrete manholes with nominal sizes greater than DN 1250, but not exceeding DN 3000, are also specified. The manholes are intended to be installed in carriageways of roads (including pedestrian streets), hard shoulders and parking areas for all types of road vehicles, though provision is also made for units subject to lighter traffic loading. Requirements for soakaways, landing slabs and corbel slabs are also specified. BS EN 752, BS EN 1295-1 and BS EN 1610 deal with the planning, design, installation and testing of drains and sewers.

Journal of Applied Mechanics,
Vol. 68, No. 1. (2001),
pp. 87-92.
The Timoshenko beam theory includes the effects of shear deformation and rotary inertia on the vibrations of slender beams. The theory contains a shear coefficient which has been the subject of much previous research. In this paper a new formula for the shear coefficient is derived. For a circular cross section, the resulting shear coefficient that is derived is in full agreement with the value most authors have considered "best." Shear coefficients for a number of different cross sections are found.
