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
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
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
A 32-page, full-colour pocket guide in A6 format. This document summarises clearly the requirements for TG20:21 compliant scaffolding and offers indispensable guidance to the scaffolding operative on-site. Price is £9.50 per copy for non-NASC members and £4.75 per copy for NASC members. Members wishing to place an order for 100+ copies must email sales@nasc.org.uk as further discounts apply.
The TG20 Operational Guide contains detailed practical guidance for most common types of scaffolding, supported by structural research and calculation. Guidance is provided for a range of standard structures which includes independent scaffolding, interior birdcages, chimney stack scaffolds, loading bays, ladder-access towers, free-standing towers, lift shaft towers, putlog scaffolding, exterior birdcages, tube and fitting mobile towers, tube and fitting loading bays without beams, and tied independent scaffolds with three inside boards. NASC members can purchase 10 or more copies of the TG20:21 Operational Guide book at the discounted rate of £25 per unit. To do so, please email sales@nasc.org.uk
Aluminium tubes, prefabricated beams and other components are widely used throughout the scaffolding industry. Whilst aluminium is not as stiff as steel and will deflect more when subjected to equivalent loads, it is much lighter and provides great advantages with regard to manual handling or the reduction weight. As aluminium couplers are not readily available, aluminium tube and beams are invariably connected with steel couplers and joint pins. Unfortunately, when two dissimilar metals such as aluminium and steel are in contact, a phenomenon known as ‘galvanic corrosion’ can occur where the corrosion of one of the metals, in this case aluminium, can be greatly accelerated. In severe cases this could seriously affect the integrity of the scaffold structure.
In order to be able to visually identify EN74 certified couplers, this guidance document identifies the specification and minimum markings to be found on all EN74-1:2005 and EN74-1:2022 scaffold couplers, together with brief details regarding the differences between the two standards. This product is available in PDF format only.
