Pedestrian Parapets

Pedestrian parapets are generally installed on bridges, retaining walls and other structures where vehicular traffic is excluded but where pedestrian, equestrians or cyclists may be carried.

The design requirement for pedestrian parapets to design load classes 3 and 4 are set out in BS 7818 and include criteria for post, rail and infill loading, deflection and minimum heights.

All welders involved in the production welding of steel pedestrian parapets are required to hold approval to BS EN 287-1 and work to weld procedures approved to BS EN 288-1, BS EN 288-2, and BS EN 288-3.

Height requirements for the parapets vary according to their location and their usage.

With the exception of locations with equestrian access, parapets over railways require higher parapets than those over non railway locations.

Table 1 of BS EN 7818 details parapet height requirements for various usages and these are summarised as follows :-

Parapets not over railways

Parapets for locations with pedestrians access are typically 1150 high above the adjacent paved surface.

  • For locations where there is cycle access the height above the adjacent paved surface is 1400.
  • For equestrian access the required height is 1800 above the adjacent paved surface.

Parapets over railways

  • For locations where both pedestrians and cyclists have access, the height above the adjacent paved surface is defined as 1500.
  • Locations with the equestrian access require a height of 1800 above the adjacent paved surface.

Other considerations

Structures requiring pedestrian parapets are frequently complex and involve raked or spiral ramps, cranks, and turns, access stairs and landings.

Because the fixing of pedestrian parapets to the structure is generally by means of cast in cradle anchorages and with due regard to the frequently complex layout, close co-operation between the main contractor and parapet fabricator is essential.

Where necessary, post drilled anchors can be used to fix the pedestrian parapets but consideration should be given to the positioning of the reinforcement to avoid conflict during the drilling process.

A mutual understanding of the tolerances available in the parapet construction is also necessary to ensure a satisfactory outcome to the installation process.

The incorporation of handrails on ramps and stairs to assist the elderly and disabled is not unusual.

Cole Ironcraft have many years experience in the fabrication and installation of pedestrian parapets to both standard and special designs, and to most structure configurations. An instalment service is available if required.
