Limits of Scoot of Work and Liability
We have based our structural capacity determination on applicable building codes,professional engineering inspection and design
experience,opinions and judgments.The calculations produced for this dwelling's assessment are only for the proposed solar panel
installation referenced in the stamped plan set and were made according to generally recognized structural anlaysis standards and
procedures.
