EXPERT TESTIMONY

A-D Engineering Group Ltd. possesses expert knowledge and experience in many fields of structural analysis, design and construction. As a result, A-D Engineering is frequently called upon to investigate and provide opinions on failures or behavioural problems which have occurred due to design or construction errors and deterioration of existing structures. Some examples include alleged damage caused by vibrations of nearby road or other construction work and disputes regarding the quality of work by contractors.


A-D Engineering will provide full detailed reports that summarize our investigation, observations, and opinions regarding these matters. In addition, members of the firm will often make appearances as an expert witness for arbitrations or litigations. A-D Engineering will also provide recommendations and outline procedures for remedial work.
