Lowest is not automatically best

A lower adjusted total may still omit performance, durability, accessibility or compliance features.

Professional review

Major proposals should be reviewed by qualified local professionals.

Important: Requirements, permits, accessibility duties, environmental rules, workplace-safety obligations, product standards and inspection practices vary by country, province or state, municipality, building use, existing conditions and adopted code edition. Qualified local professionals and the authority having jurisdiction must determine what applies.
