The Pennington County Commission authorized a 5 year construction warranty on the downtown parking ramp.
Heavy Constructors, the contracting company, offered the warranty after discovering the wrong kind of fasteners were used.
The warranty allows for a panel to be removed once per year to see if there is any corrosion on the fasteners.
Mike Kuhl the Project Manager says the issue came into light during the wind storm last year.
"Last October there were some panels that were blown off and that was when the issue was identified that the correct type of fasteners were not used with the type of plywood used in the structure," explains Kuhl.
Kuhl says the contractors told him as long as they stay dry they will be fine and so far there is no corrosion.
