In some loading dock areas floor space is at a premium, in an application like this it is common to install the dock leveler just outside the overhead door in a free standing frame. If there is an existing facility that requires an additional loading dock it is common to research what services (gas, electricity, water, drain etc.) are below the existing poured concrete floor. If there are no services under the slab a pit is constructed, if there is services below the poured concrete floor it is common to use a dock leveler free standing frame as opposed to excavating and re-routing the services.
