Explanation
BACKGROUND: This legislation authorizes the Finance and Management Director to modify a contract with Messer Construction Company in the amount of $3 million for construction of the 111 North Front Street building and the parking garage at 141 N. Front Street. A modification of this construction contract is necessary due to unforeseen items related to the location and removal of an underground gasometer tank that is associated with the parking garage property. The underground gasometer tank held petroleum product that was used to supply fuel for the previous building on this site that was torn down years ago by previous owners. During excavation work, the underground tank was uncovered at the foundation for the current parking garage construction location. Although extensive soil borings were conducted, the original preliminary studies and site borings did not uncover the underground tank during the project design phase.
Due to the size of the gasometer tank, further testing, engineering and construction services were needed. Since this structure was an unknown factor in the original design and associated cost estimate, a contract modification is necessary to expand the scope of services. The contract scope will now include the removal of the gasometer tank, which required additional soil excavation, an increase in the number and size of piles to support construction of the garage, as well as additional construction tie backs, soil remediation, soil testing, soil backfill and compaction.
The original contract with Messer Construction Company was formally bid and was established pursuant to Ordinance 1792-2015.
Original Contract Amount (1792-2015): $73,750,000.00
Modification No. 1 (2281-2015): $354,000.00
Modification No. 2 (current): $3,000,000.00
Total (Original and Modifications 1&2): $77,104,000.00
Emergency action is requested so that this construction project is adequately funded and construction can continue without delay. ...
