I haven't done Engineering Studies, but I was looking at a report on aeronautical engineering. From the looks of it, I assume it received a high mark (most likely a band 6).
Based on the abstract from that report, you could begin your abstract by saying something like:
"This report is compiled to meet the Syllabus Requirements for Preliminary Engineering Studies".
and then elaborate by stating what your report will cover through something like:
"
Following the (relevant chapter/module), the following areas of study will be addressed:"
and then go from there.
I hope this helps!
