As City Council may recall, a roof assessment report was completed by the City Engineer on November 24, 2015.  The report identified several defective areas in the front roof due to the age of the roofing material.  Extensive granule loss, numerous patches, and areas of deteriorated sealant and membrane were the cause of the water intrusion.  Several of the areas had previously been repaired and failed.  The report concluded that repairing the front roof section would not be cost efficient.  The recommendation was for the north roof section to be replaced with a thermoplastic polyolefin (TPO) roofing membrane.  The report further recommended no action be taken with the south or rear roof section due to an estimated 10 to 12 years of service life left.            

On April 19, 2016 subsequent to staff request,  City Council approved the bid award and agreement for the incubator front roof replacement to Professional Roofing Systems, Incorporated. Construction began on July 12, 2016 and continued sporadically thru the summer.  On September 6, 2016 the City’s Construction Services Division sent the Contractor a listing of corrective work items to be completed prior to the project completion date of September 28, 2016.  The Contractor informed the City they felt as though the project was completed and invoiced the City.

On November 18, 2016 Engineer’s from BillerReinhard Engineering Group Inc. performed a visual survey of the newly constructed front roof and submitted a report to the City on December 2, 2016.  The report concluded substantial deficiencies in the as-built construction of the new front roofing system and concluded that the newly installed roof system will not function properly to protect the building for its intended use or withstand the life of its intended warranty.  Defective workmanship was attributed to these defects.  In conclusion, the report recommended the existing TPO roofing system be removed and replaced.

Subsequent to discussions between staff and the City Attorney, it was agreed that both the Contractor and the Contractors performance bond insurer should be notified of the City’s intent to replace the front roofing system and allow them the opportunity to perform corrective action under their current contract.  In addition, it was agreed that in order not to waste time, staff would proceed with the design specifications and bid process so that if a resolution could not be obtained between the City and the Contractor the City could still get the front roof replaced prior to this year’s rainy season.  As of this date no reply has been made to the City from the Contractor. As for the Contractor’s performance bond insurer, all information requested has been submitted by the City to the insurer with no response.

The Engineer of record has reviewed the submitted Invitation to Bid from SC Signature Construction, Inc. for omission and errors and has confirmed the ITB has met all of the requirements called out by the City.  Professional references have been verified and spoken with and the engineer has submitted a recommendation memo as part of this packet for City Council’s review.
