As part of the Pipe Bridge Maintenance Painting Scheme, MLM was commissioned by the National Grid East Coalition to carry load assessments of existing pipe bridge structures and to act as the independent checking engineer for the temporary works at four sites within the National Grid’s East Midlands region. As no record drawings existed MLM undertook structural surveys of all the structures to determine member sizes and connection details to enable load assessments to be carried out. This included the use of rope access techniques and ultra-sound thickness measurement to determine wall thicknesses of tubular members.

Working in conjunction with the scaffolding contractor, load assessments of the structures enabled the limits of the temporary scaffolding platforms to be determined. An independent design check was carried out by MLM on the scaffold designs produced by the contractor prior to its erection. Site visits were undertaken to ensure the scaffold was being erected in accordance with the certified drawings.

Additional works included the reporting and advising on localised corrosion repairs, and the removal and replacement of gas main supports.
