Fibrelite Design And Engineer Retrofit Replacement For Heavy Cast Iron Recess Access Covers With Concrete Infill

Read the Case Study

Project Overview

Fibrelite were contacted in May 2021 about this upgrade project and shortly thereafter Fibrelite were invited to conduct a site survey. This client desired a simple replacement for their previously installed heavy cast iron recess (access) covers with concrete infill. The retrofittable design and engineering solutions offered by Fibrelite meant that they would be an ideal candidate for manufacture and supply.

Previous installed access covers required a crane to remove and replace

Problem

The previously installed cast iron and concrete access covers were very heavy. This caused frequent operational difficulties for the customer which they considered manageable for some time. After a certain point, the site managers decided that the cost and health and safety risks posed by these heavy cast iron recess covers were no longer tenable.

Key difficulties with previously installed access covers and requirements for replacement:

  • Removing and replacing the cast iron and concrete access covers necessitated specialist machinery (a crane) and training for operatives.
  • Existing key housings had corroded/deformed, adding to the difficulty incurred during removal.
  • The replacement covers needed to be stepped 84mm to 117mm deep to accommodate the existing frame as the customer did not wish to break out concrete if possible.
  • The replacement covers needed to comply with the D400 load rating.

Solution

Shortly after the site survey, the Fibrelite technical team were able to provide a proposal which would meet the requirements mandated from the outset by the customer. The site survey and proposal were completed quickly, which was pleasing to the customer who were keen to quickly implement this upgrade. Fibrelite’s replacement solution was engineered and delivered to the required specifications.
