Complete and Safe Demolition Site It is the intent of this specification to require demolition work that brings the site clear of buildings, structures, equipment, and utility services, but to retain impervious surfaces in order to prevent ground erosion to occur. Also the intent is to leave the site safe from tripping hazards, protrusions that could cause harm, and depressions that would be walking hazards. Once the demolition work is complete the surface of the site shall be safe and non- erodable. All spoils from the demolition work shall be removed from the site by the Contractor. Bid pricing shall reflect these requirement. It is not possible to specify or describe every detail of work required to complete a project of this nature or to predict problems that might be encountered. The successful Contractor will be required to provide all labor, equipment, tools, specified material, and incidental items necessary to undertake the demolition work and complete the project, as described herein, resulting in fully prepared and functional sites that perform to their intended purposes. Minor omissions from the specification or drawings shall not relieve the Contractor from the obligation to provide the completed project that is fully functional as intended by the Owner. Failure of this specification to describe each detail or incidental item necessary to a complete and functional project shall not entitle the Contractor to additional charges. Examples of items that will not be considered as basis for claims for additional cost are, but shall not be limited to, minor relocations, minor changes in the demolition plan, differences in the actual surface of the site from that shown on the demolition plan, reasonable weather delays, site cleanup, etc. Further, all work shall be performed and completed in a thorough, safe, and workmanlike manner and shall follow the best modern recognized practices, notwithstanding any omissions from this specification.
