However, if the insured obtains a lower-cost alternative repair recommendation from a professional engineer for stabilizing the land or the building and repairing the foundation, the insurer must pay the cost, not to exceed the policy limits, to complete the lower-cost alternative repair upon the insured's entering into a contract to repair the sinkhole loss in accordance with the lower-cost alternative repair recommendation by the insured's professional engineer. Such lower-cost alternative repair shall be subject to reasonable cost adjustment by the insurer; however, the insurer may not depart from the engineering requirements of the insured's professional engineer's lower-cost alternative repair recommendation. Except when payment for sinkhole loss is made under paragraph (a), the insured is responsible for the amount of the repair costs in excess of policy limits, if any.
