About Us

Qalchek Pty Ltd was established in December 1993 when Sydney Water first announced it was implementing private industry providing a Quality Checking role for Developer works to commence in April 1994. Qalchek started with two permanent staff and one part time employee.

Due to Qalchek’s rapidly growing work load and request from clients to provide design services Qalchek expanded its capabilities into design area. The Company has now grown to a staff of 28.

We are a fully quality assured Company with regular external audits carried out by SAI Global. Qalchek has obtained full capabilities accreditation with Sydney Water for the following roles:
