There are many ways to structure references. Even using the Harvard system it can differ.
Here are the 3 versions of the Harvard system that Word generates:
Thompson, NJ, Philp, D, Barker, C, Rebecca, H-J, DeCicco, R, Beaumont, W & Atkinson, 2014, ‘Built Environment 2050: A report on the digital future of our industry’, Construction Industry Council, Construction Industry Council UK, London.
THOMPSON, Neil J, David PHILP, Chris BARKER et al. 2014. Built Environment 2050: A report on the digital future of our industry. London: Construction Industry Council UK.
Thompson, N.J. et al., 2014. Built Environment 2050: A report on the digital future of our industry. London: Construction Industry Council UK Construction Industry Council.
The last one is one that I wouldn’t recommend using.
