    Why Us and How Are We Different?

    Firstly, we provide a fully integrated service which combines the two key elements of construction claims – time and money!

    Our in-house quantum and commercial expertise, coupled with the planning and delay analysis expertise of our partner firm, ensures that we embrace all aspects of construction claims and disputes and provide Expert Witness services across the whole construction spectrum.

    We fully understand the issues that our law firm partners experience with construction disputes and claims, as despite their expert legal and contractual knowledge, their understanding of the practical and financial aspects of the construction process may not be at that same level – this is where we come in!

    With our extensive and detailed knowledge of construction, gained from many years of working on and delivering construction projects, we are ideally placed to add construction and commercial expertise into the legal process.

    Whilst theoretical knowledge of construction is inherent within surveying practices generally, we are completely different, because all our senior commercial staff are from contracting backgrounds.

    As a result, we have:

    Held numerous and varying roles within construction companies over many years, including quantity surveying, estimating, design management, bid management, planning, site and project management – this variety of experience and skills enables us to confidently address all practical and financial aspects of construction claims.

    ‘Been there and done that’, as we have all played active senior level roles during live construction projects, and have delivered numerous major construction schemes on site, so our knowledge is also practical, not just theoretical.

    Many of the problems which arise during construction projects emanate from commonly repeated issues, which in turn result in poorly prepared claims documents.

    We help resolve this by undertaking a detailed review of all the documents provided at the outset. This invariably informs a request for further or outstanding information, which, when received, we then interrogate intensively and forensically as part of our assessment and our Expert Witness report.

    Ultimately, we know construction and construction contractors, as we were once part of them. So, there is little that we have not seen or experienced – this has significant appeal to our clients and sets us apart from many of our competitors!
