Get Valuable Insights on Pricing and Apportioning of Costs Associated with Design Defects

Preparing a successful design involves the application of scientific skills and technical expertise to achieve owner requirements while adhering to professional standards. Developing a completed design in a perfect manner is difficult, if not impossible. Accordingly, it is common for construction projects to experience, at some level, corrective changes to the work resulting from professional design deficiencies. These corrective changes can involve work which result in damages being incurred by various stakeholders, for which recovery is oftentimes sought from the design professional. The liability for such claims are generally aimed against the designer on the basis that it failed to satisfy its contractual obligation to provide a design meeting the necessary functional and operational expectations while complying with the requisite professional standards. A common question in this regard is how an appropriate assessment for the corrective actions or work gets calculated.

This presentation by  our expert speaker, Peter Vosbikian, who has over 20 years of experience in construction, civil engineering, and construction program management, will provide valuable insights on the pricing and apportioning of costs associated with design defects, contract provisions addressing the pricing of design defects, and demonstrate, by example, how to calculate an assessment against an A/E.

Whether you’ve experienced a damage resulting from a change, or involved in a claim due to design changes, this session will provide you needed knowledge on how to quantify damages associated with a design deficiency. It will also provide valuable insights on how contract language can manage risk associated with design deficiencies.
