structural strength to support the maximum crane load; and
80
(b) if the geotechnical report described in Subsection (1)(a) states that the soil and
81
subgrade conditions of the real property on which the improvement will be made
82
cannot support the maximum crane load, the owner shall design, develop, install, and
