About Us

IntDesign Pty Ltd is establishing a fresh approach to CHPP design, construction, optimization, upgrade
and commissioning by working closely with clients, suppliers and constructors from very early in the
project cycle. It is our aim to integrate the specialty skills of each group involved with the engineering

To enable this early integration, it is essential to select the appropriate method of delivery for the specific project. IntDesign offers consulting services in this area to enable clients a structured approach to delivery method selection.

Following selection of the appropriate delivery method, IntDesign will work with the client to engage the appropriate suppliers and constructors early in the design process to enable the streamlined delivery of the project.

Early integration of all stakeholders in the project has shown benefits in delivery timeframe, costs,
rework requirements, safety in construction and commissioning, and continuity in the service
following project completion.

IntDesign Pty Ltd also offers services following any greenfield deliveries, or plant upgrade projects. We are able to offer advice in ongoing process optimization, planning of service and audit works,
recommendations on software implementation relevant to multiple tasks within process plants, onsite
inspections and advice, and short term secondments to sites for key personnel replacement.

IntDesign Pty Ltd focus on providing safe, professional services to our clients and aim to becoming part of our client’s team in all works undertaken.
