Project overview
The development at 107–109A Hendon Avenue comprises a 9-lot residential subdivision within an established urban area, delivering new housing supported by upgraded three waters infrastructure. Calthom provided civil engineering design, construction observation, and project completion services, supporting the delivery of the subdivision and associated works. During construction, discrepancies in existing wastewater infrastructure records—stemming from previous works associated with the Waterview Tunnel—introduced unforeseen challenges. Our involvement included managing these complexities on site and working through the necessary coordination and approvals to achieve a compliant and successful outcome.
