46 BUILDING FABRIC
As factory manufacturing can be scheduled to start as the site is being prepared, processes can run in parallel, helping to reduce waste and the movement of vehicles. This can also create less disruption to residents or businesses close to the construction site.
WORKING AT HEIGHT
Health and safety issues are signifi cantly reduced by constructing away from the hazards of a building site. For example, roof truss and oor joist systems can be manufactured and supplied to carefully coordinate with planned delivery sequences to complement the build programme. This can result in fewer deliveries, minimising the requirement for onsite manual handling and unloading.
As we have learnt, falls account for 50% of all construction injuries, so reducing the frequency and duration of working at height is accepted as one of the best ways to limit accidents. In addition, the ongoing skills shortage in the industry may compound the problem, where there may be a reliance on temporary labour. Manufacturing engineered trussed rafters and oor solutions in a controlled environment – and prioritising offsite work can help signifi cantly reduce the need for working at height. These effi ciencies carry through to the construction site – with many component parts pre-installed, so there is no need to work off scaffolding or ladders. Alongside the clear productivity improvements, the quality-controlled environment relies on a skilled, permanent workforce. Numerous measures will be in place to ensure that the production process is effi cient and systematic, most likely including a target
of zero lost-time incidents. Checking a supplier’s credentials for externally recognised certifi cation, including the ISO45001:2018 Occupational Health & Safety Standard, is a good starting point.
MATERIAL SPECIFICATION Respondents to the Housebuilder and Developer survey also commented on the importance of the correct material specifi cation, and the requirement to ensure site deliveries meet the latest safety regulations. 25% of respondents agreed that keeping up to date with fi re regulations was the most important to their organisation – the second most common requirement below health and safety.
This is another area where using offsite manufacturing techniques can pay dividends. Contractors have the assurance that materials have been stored correctly, processed and then fi nished to strict quality standards and a defi ned audit trail. These standards will dictate everything from the material’s regulatory compliance to its sustainable credentials andor FC certifi cation to its suitability within the fi nished building.

Glidevale Protect provides complete roofi ng ventilation solution for new build housing development
L
eading building materials manufacturer, Glidevale Protect, has supplied its Protect Viking Air pitched roofi ng underlay across a new build development for housebuilder Pennyfarthing Homes in Verwood, Dorset. Glidevale Protect’s high-performance air and
vapour permeable roofi ng underlay has been installed by appointed roofi ng contractor Ford Roofi ng of Hampshire at Pennyfarthing Homes’ Potters Wood housing scheme, a bespoke development featuring a mix of new build two, three and four bedroom semi-detached and detached homes. The Protect Viking Air roofi ng membrane
was fi tted across all the pitched roofs, including on apartments at the development. The class-leading underlay helps avoid the risk of harmful condensation and achieves superior air permeability, tested at 50 Pascals to BS EN 12114, meaning it can be used in cold roof construction without additional roof space ventilation as accepted by the NHBC. Glidevale Protect’s premium underlay boasts the best air and vapour permeability on the market. It is independently certifi ed by BM TRADA as well as having the strongest wind uplift resistance of its product type, making it able to be used in wind zones 1-4 at 345mm batten gauge, in accordance with BS 5534, without the need for additional counter battens or integral tape. This ensures Viking Air
can be used across a large area of the UK and throughout Ireland. Used in both cold and warm roof
construction without the need for additional ventilation, thereby saving labour costs by avoiding the need for additional accessory products, Viking Air can also be wrapped over the ridge rather than needing to cut it short on
