Openreach Approved Chamber System

Description

The BT openreach approved systems provide contractors with a means of constructing access chambers quickly and inexpensively, whilst offering improved build quality, reduced defects and enhanced site safety performance.

Using these systems, complete chambers can be constructed from excavation to reinstatement in little more than one hour.

Features & Benefits:

Fast and easy to install
The chambers are significantly faster to install than conventional alternatives, with complete installations typically taking up to one hour. This results in reduced costs for the installer. No specialist equipment or plant is required in order to install the chamber and there is no need for specialist box builders.

Sectional & twin wall design.
Chambers are built to required depth by adding 150mm sections. Due to the twinwall design, individual sections are light meaning they can be manually lifted. Each access chamber possesses vertical and horizontal ribs, resulting in a product that is strong vertically and on the sidewall. They do not require specialist backfills, reducing installation costs.

All weather construction.
Unlike with brick-built chambers where freezing temperatures can stop work, chambers can be installed in all types of weather.

Smooth outer walls with lip to ‘key in’.
Gaps in the outer wall will negatively impact the effectiveness of compaction around the chamber. The approved chamber sections have smooth outer walls and an outer lip which keys into the backfill.

Flexible during installation.
Chambers can be adapted to suit on-site conditions with standard tools.

Overbuild over existing networks.
Introduce duct entries for cable entry. Recommended spacing, in line with BT Quality checks, is indicated on the chamber.

Drop-in furniture and steps.
Cable management and steps are fitted by dropping the accessories into pre-formed pockets. These allow accessories to be retrofitted after installation without mechanical fixing.

Meets requirements for BT Openreach quality checklist.
BT Openreach checks all chambers against 13 step Quality Checklist for its brick, concrete and joint boxes. When using openreach approved sections, this checklist is reduced to 8 checks.
