GENERAL INFORMATION:
The submitted documents for the above-mentioned project, as outlined in the cover letter, have been reviewed. The following comments address areas of concern, non-compliance with the
governing code, potential errors, or omissions in the proposed design. The appropriate design professional must address each comment below and submit a written response in addition
to revised plans and calculations if necessary. Please cloud any revisions made to the construction drawings and provide the date of the latest revision on each revised sheet.
GENERAL COMMENTS:
Please confirm the location of piles. Sheet SH4.0 detail SU3 appears to show the soldier pile extending beyond the property line. This is either not permitted or will require an easement
related to the adjoining property owner.
Please specify how foundation drainage which is shown on the building plans will be located on the podium property. If the soldier piles will stay after the construction of the foundation
occurs, there appears to be no space provided for the drainage. This also may require an easement with the adjoining property owner.
Please provide detailing if soldier piles will remain after the completion of the foundation, showing how damp proofing or water proofing will be applied. STRUCTURAL COMMENTS:
