(a) relies on a certificate under section 238 of the Act by a fire safety engineer, who did not design the building work, that states that the performance solution complies with that performance requirement; or
(b) relies on a determination of the Building Appeals Board under section 160A of the Act that the performance solution complies with that performance requirement; or
(c) relies on a certificate of accreditation issued by the Building Regulations Advisory Committee that states that the performance solution complies with that performance requirement; or
