sample gantt chart

Hi anyone out there that can help me with a sample gantt chart, I’m starting project management and would like a sample of building project starting from the design stages then approval and implementation to construction phase..possibly listing resources and costs

I’m preparing a cost assesment task and your help would be appreciated , if not perhap direct me to some weblink

If there’s someone from australia that could help that also would be much appreciated

thank you
