Overview

The Board of Trustees of Baverstock Oaks School is looking for a main contractor to address works required to remediate its elevated walkways:
• Steel connections between blocks and suspended walkway are poorly connected and must be remediated per structural engineer’s design
• Seismic joints between Blocks A, B, C are poorly constructed and must be remediated per structural engineer’s design
• Structural steel framework is corroding at joints and needs to be waterproofed and treated with zinc rich primer
• Steel inclined posts near stairwell have been built with poor connection and must be remediated per structural engineer’s design
• Cable trays that support the services underneath the walkways have corroded and will need to be replaced in accordance with seismic restraint/detail requirements of NZS4219:20019
• Spalling of concrete on upper floor landing on exterior stairwell are breaking loose – this must be wire brushed to remove all surface rust, apply Sika Monotop to reinforcement and level the mortar to existing floor
