841.01 Description.
The work includes all labor, equipment, and materials necessary to conduct pre- and post - construction condition surveys of all structures and/or properties identified in the Contract. In addition, the work includes conducting structure condition surveys of all structures within 200 ft for all vibration-inducing activities resulting from the Contractor’s construction. The following identifies the structures that require condition surveys or any other structures identified in the Contract: • Existing bridge foundations, abutments and piers, and superstructures • Private commercial and residential buildings and other structures • Retaining walls • Culverts Submit a comprehensive list of all affected properties and structures as part of the P roject schedule development process. Conduct p reconstruction surveys before the commencement of construction operations and vibration-inducing activities. This includes driving and removal of piles and sheeting, drilling, boring, blasting, structural demolition, and any other vibration-inducing activity resulting from the operations. Do not initiate any work that may result in damage to properties or structures until all preconstruction survey reports have been submitted and approved by the Engineer. Perform post-construction surveys upon substantial completion of the C ontract with the consent of the Engineer, and follow the same procedures and protocols used for preconstruction surveys.
841.02 Qualifications and Submittals.

Conduct p re-construction surveys before initiating construction operations and all vibration - inducing activities. Ensure that the d ocumentation includes photographs, video, sketches, and a written report of findings. Provide v isual imaging for pre- and post -construction surveys that includes high resolution color image acquisition in a format compatible with subsequent image enhancement analysis and feature extraction. Provide adequate lighting equivalent to a minimum of 55- watt bulb illumination during still and video photography. Emphasize the following: • Locations and sizes of cracks in interior and exterior walls, floors and ceilings, and missing mortar, plaster, or other surface materials • Damaged masonry, chimney liners and flues, and roofing, including evidence of leakage or poor roof/gutter drainage such as staining • Damaged or out-of-square doorways and windows including tightness of fit and ease of operation • Walls that are not plumb, floors or ceilings that are not level, and walls, floors, or ceilings that are uneven and the extent to which they are not planar • Condition of the foundation walls and basement floors, especially cracking, differential movements, and signs of dampness or moisture • Condition and grading of the ground surface around the exterior of the structure including evidence of drainage towards walls, low spots that pond water, and cracks and irregularities in asphalt, concrete, brick or stone pavements, sidewalks, and steps • Evidence of previous repairs to the structures • For post-construction surveys, all changes from the pre-construction survey Perform a post-construction survey upon substantial completion of the Contract. If the Contractor and/or survey engineer are unable to gain access, encounter difficulty , or are refused entry to a property, document the refusal in the report and inform the Contractor and Engineer of the incident in writing. Absent a resolution, the survey engineer shall limit the structural condition survey to information that may be gained from observations outside the structure or property boundary, and document the findings in the final report. Repair all damage sustained by the properties or structures surveyed due to construction operations to the satisfaction of the Engineer at no additional cost to the Department or property owner.
