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.
