The merger has brought together a team of engineering professionals with decades of combined experience in the construction and building science industry, who pride themselves on providing high quality services to clients with the utmost integrity, reliability, and efficiency.


“Over the past 2 years, we engaged JSD to conduct a Building Envelope Condition Assessment and a Depreciation Report/ Contingency Reserve Fund Study as well as to manage a major Building Envelope Remediation project. In all cases I found Sam and his team to be highly professional, knowledgeable and customer focused. They provided sound advice, their deliverables were of high quality and they were always available to answer questions and to provide opinions and advice as required. They always kept their commitments.

I would highly recommend JSD to any Strata in need of building envelope engineering and/or delivery of a Contingency Reserve Fund study.”
