You need a good technical work with a structure similar to that of a standard technical paper. I will use all my experience (I have published over 70 technical papers for international journals and conferences) to do this work.. For you to earn maximum marks, it is important to strictly fulfil the criteria given in the "Guidelines" (such as specified number of words, Tables, Figures, References etc.) and in the "Marking Criteria". I will strictly adhere to these and will make sure that all the ingredients of the Marking Criteria are there in a way that will give you maximum marking.
Please see my profile. I am a Ph.D. in Civil Engineering and the assignment that you have is something that I do regularly for real-life projects as part of my work. I assure to produce a work of highest quality.
I have a question for you. It is not clear from the attachment what field of civil engineering this abstract will be based on. Do you have any preferences?
