- FRICTION in Temporary Works
First published in the June 2002 edition of CONCRETE magazine is the article summarising the UK research work on friction. The date is also introduced into BS 5975:2008.
The friction resistance using “wet” timber and plywood has shown that the values previously published for DRY timber and plywood are acceptable lower bound values. Surprisingly, wet and saturated timber and plywood gave higher values than when dry - believed caused by the individual timber fibres compressing when wet and making a "rougher surface". - A Guide to the safe transportation of formwork and falsework equipment

CS140 - GUIDE TO FLAT SLAB FORMWORK and FALSEWORK
Now available - published A4 by the CONCRETE SOCIETY - June 2003 at £60.00. The Flat Slab Guide is prepared by a CONSTRUCT working party under chairmanship of Peter Pallett under an initial PiT proposal with The University of Birmingham. It introduces some very informative and innovative methods for striking flat slabs and, very importantly, introduces detailed guidance, with examples, on backpropping of multi-storey buildings based on BRE Report BR 394. The Excel spreadsheet included with the Guide will quickly become the essential tool for PWD's and TWC's in planning backpropping operations.

- Concrete Groups for formwork pressure
Users of CIRIA report R108 need the relevant concrete group for determination of the pressure of concrete on formwork. Additional research has been carried out to advise CIRIA about the pressures for a range of superplasticised and self compacting concretes.
Peter Pallett's article in CONCRETE magazine March 2009 (page 44 & 46) relates the new cement designations to the factors used in CIRIA 108.The working party currently updating CS030 Formwork - a guide to good practice have recommended that to avoid confusion in future, the industry classifies pressure determinations into three groups, as opposed to the seven groups currently used. These will be:-
Group A - Basic Concrete ( Formerly Groups 1 & 2 )
Group B - Retarded Concrete ( Formerly Groups 3, 4 & 5 )
Group C - Heavily Retarded Concrete ( Formerly Groups 6 & 7 )

- Self-compacting Concrete
The Concrete Society Technical Review TR62 was published in June 2005. It provides a basic understanding of applications, properties, design and practical considerations of use of SCC. Written in response to industry requests. Concrete pressure covered in two paragraphs, recommending, in absence of any data, use full hydrostatic head.

The article by Yannick Vanhove of work carried out in France on concreting TWO 12m high columns with Self Compacting Concrete is summarised in an article in the June 2002 edition of CONCRETE magazine. They pumped one column from the bottom upwards, and the other more conventionally by skip from the top. The report introduces a modified Janssen formulae allowing for the friction of the face contact maerial and the type of release agent used. The results showed that, compared to full fluid pressure head, there was a reduction in SCC pressure of about 30% for the poured concrete by skip, and about 20% for the bottom pumped SCC concrete.

Published in September 2003 by CIRIA, these major new references for all those involved in façade retentions include detailed design information and practical guidance. The CIRIA committee, under the chairmanship of David Thomas (HSE), must be congratulated for bringing together the differing design approaches previously used in the industry into one unified design approach.

The HSE 200 page report is available as Contract Research Report CRR 394/2001 from HSE Books as ISBN 0 7176 2232 0. It is also available for download from www.hse.gov.uk/research/crr_htm/2001/crr01394.htm (2.5 Mb).The work was carried out by the University of Birmingham, led by Eur. Ing. Peter Pallett with help from Dr. M. Burrow, Professor L. Clark and Mr Ray Ward. The research investigated both the aspects of stability of falsework and measured eleven sites for accuracy of erection. The changes in management of falsework, together with more reliance on suppliers' designs has led to different criteria and checking regimes.
- “There does not appear to have been an overall improvement in verticality of erection over the last 12 years. ”
“At all levels there is a lack of understanding of the fundamentals of stability of falsework and the basic principles involved.”
Scaffolding and Towers
- TG20:08 Scaffolding Guidance
TG20 was published in November 2008 as two volumes. The general guidance and four summary tables of safe height for Basic Unclad scaffolds, with or without inside boards, ( 1 or 2 allowed ) are in Vol. 1 (120pp). For ease of use, the detailed structural calculations, 36 advanced tables of safe heights together with worked examples of unclad independent tied scaffolds are in Vol. 2 (128pp).
It introduces a simple and effective concept of scaffold designation using three numbers, e.g. 3-5-2. The first number is the Service load class, (i.e. Class 3 for 2.0 kN/m² ), second number is number of 225mm boards between the standards, and the third number represents the number of scaffold boards cantilivering on the inside of the scaffold as either 0, 1 or 2. This will facilitate ease of procurement and provide users of scaffolds a quick understanding of what it was designed for.
ERRATA: Vol. 2 Table 24 Page 145 - The safe slip load of a Swivel Coupler (Class A) is 6.1 kN not 3.6 kN, and the safe slip load of a Swivel (Class B) is 9.1 kN not 5.5 kN.

The Health and Safety Executive published on 1st August 2008 a three page "Revised Scaffold Information Sheet". It confirms all scaffolds have to be designed, unless it is a basic scaffold to the NASC Guidance TG20.(OBTAIN FROM: http://www.hse.gov.uk/construction/scaffoldinginfo.htm
- Work at Height Regulations Question and Answer Brief - Question 24 Scaffolding
The Health and Safety Executive revised their website Question 24 in January 2006. The revised and corrected text is:Question 24. What about scaffolding? Do I have to design scaffolding? What is a generally recognised standard configuration?
Answer. Most scaffolds can be erected following a generally recognised standard configuration. Such as those given in the National Access and Scaffolding Confederation (NASC) guide TG 20:08, or used in accordance with the manufacturers guidance for system scaffolds.
Where scaffolds due to their complexity or size cannot be erected to these established configurations they should be designed generally in accordance to the principles given in BS EN 12811 or based on fundamental engineering principles. In these cases a note of the design should be available. Competent scaffolders should always erect tube and fitting, or system scaffolds, and a safe system of work should be followed, i.e. as described in NASC's guidance note SG4:05.
( end of Q24 Answer ) See the full brief at HSE Q & A Brief as pdf file.
