Current estimates of NRMM emissions on construction sites indicate that they are responsible for 7% of NOx emissions, 14% for PM2.5 and 8% of PM10 emissions across the Capital.
In 2014, the GLA released the Supplementary Planning Guidance document ‘The Control of Dust and Emissions from Construction and Demolition’. This document outlines the NRMM standards for new engine emissions in London (chapter 7; Cleaner Construction Machinery for London: A Low Emission Zone for Non-Road Mobile Machinery). Developments are required to comply with the NRMM LEZ policy and maintain an inventory for all NRMM used on site. The inventory must be kept on site and to show regular servicing and the emission limits for all plant.
Poorly trained or unlicensed operators, badly maintained equipment, financial constraints, pressure of tight timescales or a lack of capable manpower can result in insufficient care in managing the construction site environment. This can lead to plant inefficiency and negative outcomes. TfL and Croydon Council have requested that case studies be supplied on alternative methods that can help manage this problem.
One case study included use of a ‘simple to use’ system that identifies the plant usage and user through a card reader and smart card system. By issuing each potential operator with a personalised smart card that stored data regarding their own licence and experience with equipment it was possible to understand the capabilities of the workforce, highlight training requirements, reduce unnecessary training and ensure that only competent individuals were granted access to machinery. If the user is not allowed to manage certain plant the system can set up and record instances of “denied access.”
