Daywork is a method of valuing construction work according to the time spent carrying out work together with the value of the plant and materials resources used. It is an alternative to valuing work by measurement. This guidance outlines when daywork can be charged, how it can be calculated and administration. This guidance is available for pdf download only. 4 pages
The purpose of this guidance note is to bring together, in one document, some of the more common qualifications used by members. It is not suggested that the list is exhaustive or that the wording of individual clauses is appropriate to each and every similar situation. However, it may serve as a check list for estimators. 10 pages
Other than for very small contracts most contracts of any size have a pre-contract meeting. The primary purpose of the meeting is often for the parties to clarify specific points in the enquiry and quotation. This guidance outlines items to be covered in the meeting, pitfalls and a recommended strategy. 2 pages
This is an instruction manual for managing a project and relies on knowledge, skill and expertise to operate it. The mechanisms have to be understood and complied with. Those intending to subcontract under this form should, as a minimum, obtain and read the form and its associated guidance notes. 8 pages
This guidance gives details of various methods available for satisfactorily securing scaffold boards to prevent movement. Users should satisfy themselves when/which boards require tying down and that any proprietary equipment or fixing method selected meets their requirements. This product is available in PDF format only. 4 pages
This guidance explains the differences between ‘supplementary’ and ‘check’ couplers and gives typical design applications where high coupler forces could be expected and where additional loadbearing capacity to connections may be required. It also contains guidance on coupler configurations and expected safe working loads (SWLs) where supplementary couplers are used. To ensure that SWL values are as accurate as possible, data provided within this document is based on practical testing rather than calculation. 2 pages
Many free-standing scaffolding structures, such as access towers, major signboards, fences and enclosures, need to be anchored to the ground, primarily to resist wind forces. Whilst all structures requiring restraint via anchoring to the ground should be subject to a bespoke design produced by a competent engineer, the guidance considers different types of anchors available and typical indicative holding capacities, the possibility of disturbing underground services, the use of guys and scaffold tube restraint. 6 pages
This guidance gives details of the stress corrosion cracking (SCC) that can occur in certain materials when subjected to tensile stress and specific corrosive environments. Although rare in our industry, it can lead to unexpected sudden failure of certain metals. Whilst chemical environments and alloys are highly specific, this guidance explains the process by which SCC can occur and advises that specialist advice may be needed where SCC is possible or has occurred in the past. This guidance is available for pdf download only.
