Block 88 HDB Dawson 

Dawson HDB is a high profile, centrally located residential development with heavy daily lift usage and strong expectations around durability, reliability, and aesthetics. 

The key challenge on this project was the external-facing lift components, particularly pushbuttons, which were exposed to: 

  • Water ingress from rain and humidity 
  • Dust ingress due to environmental exposure 

Previous installations using lower IP-rated components from competitor suppliers had experienced repeated failures, with pushbuttons becoming stuck or unresponsive. This created: 

  • Increased maintenance interventions 
  • Reduced reliability for residents 
  • Higher long-term lifecycle costs 

The project also required: 

  • Accurate on-site measurement and assessment to ensure correct replacement and fit 

This presented an opportunity to demonstrate the value of higher-specification, fit-for-environment solutions over standard components.

Solutions

Dewhurst supplied IP54-rated pushbuttons, specifically selected to withstand the environmental conditions affecting the external-facing lift installations at Dawson HDB. 

Key elements of the solution included: 

  • Designed to protect against dust ingress and water splashes, significantly improving reliability compared to previously installed competitor products. 
  • Higher IP-rated pushbuttons (IP54) 

Direct replacement of existing indicators: 

  • Standard indicators were replaced as part of a planned cyclical replacement programme, ensuring consistency, reliability, and minimal disruption

On-site measurement and analysis: 

  • Dewhurst conducted detailed on-site measurements and assessments to ensure accurate specification, correct fitment, and smooth installation. 

Proven performance advantage: 

  • While competitor products had failed under the same environmental conditions, Dewhurst’s higher IP-rated solution remained fully operational, reinforcing the value of correct specification over lowest-cost alternatives.
