Title
Authority to increase Contract 11-054-3P Disinfection Facilities, Terrence J. O'Brien Water Reclamation Plant, to Walsh Construction Company II, LLC in an amount not to exceed $204,268.06, from an amount of $60,659,907.84 to an amount not to exceed $60,864,175.90, Account 401-50000-645650, Purchase Order 4000005
Body
Dear Sir:
On August 8, 2013, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 11-054-3P Disinfection Facilities, Terrence J. O'Brien Water Reclamation Plant, to Walsh Construction Company II, LLC, in an amount not to exceed $59,899,650.00 plus a five (5) percent allowance for change orders in an amount of $2,994,982.50, for a total amount not to exceed $62,894,632.50. The scheduled contract completion date is December 19, 2015.
As of May 8, 2015, the effect of change orders resulted in a net increase in the amount of $760,257.84 from the original amount awarded of $59,899,650.00. The current contract value is $60,659,907.84. The prior approved change orders reflect a 1.27% increase to the original contract value.
The engineer has determined that revisions to the contract to include the addition of aeration equipment to increase Dissolved Oxygen (DO) in the O'Brien Water Reclamation Plant (OWRP) effluent are required. The new NPDES permit for the OWRP requires that DO in the plant effluent be continuously monitored. To ensure that this requirement is maintained, installation of DO equipment is prudent. In order to expedite this work, two change orders will be required. The scope of work for this change order includes furnishing and installing 316 stainless steel coarse bubble air diffusers and piping in the UV facility effluent channel and furnishing and installing two additional DO probes and a multi-channel process analyzer. This equipment needs to be installed prior to initiating flow to the UV facility. The remaining scope of work to provide an air source to the equipment can be performed after the UV facility is in operation. The second change order will require Board authorization. Authorization will be requested as soon as the cost is substantiated. The contractor submitted a cost proposal (CCO-025) for an extra in the amount of $204,268.06. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 1090, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is due to circumstances not reasonably foreseeable at the time the contract was signed, and is in the best interest of the District.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute a change order to increase Contract 11-054-3P in an amount of $204,268.06, (0.34% of the current contract value) from an amount of $60,659,907.84, to an amount not to exceed $60,864,175.90.
Funds are available in Account 401-50000-645650.
Requested, Catherine A. O'Connor, Director of Engineering, MVL:ECB

Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
