Change Request Definition
Change
Recommended by: Indian River County Solid Waste Disposal District
Description of Change/SOW Description:
Indian River County Solid Waste Disposal District (client) wants to be able to analyze the landfill gas (LFG) for its components and percent of
the components present in the LFG. Therefore, a Gas Chromatograph (GC) device is needed to analyze the LFG. To meet the operating
conditions for the GC, the GC needs to be furnished with a chiller and a pump. The chiller will reduce the LFG temperature and moisture and
the pump will increase the pressure. Included in this change order is equipment that has been requested by the IRC SWDD's controls
specialist so that the PLC at the blower skid will be used as the balance of plant for the evaporator and the main SWDD main system. This
requirement will add secure router, optic fiber switch, optic fiber rack and optic fiber cable in the blower skid panel.
Reason for Change:
Client wants to monitor LFG quality at the blower skid area. Cobtrols equipment is required to enable the PLC panel on the skid to act as the
balance of plant between the evaporator and IRC SWDD control center, as requested by IRC controls lead.

Cost increase is Lump Sum of $112,980 and is additional to the original approved amount for the PO and CO#1 as of $1,063,570. The revised
total will be $1,194,550 (including $18k estimate for shipping). Upon approval, BGE will invoice for 45% of the change order amount. The
remaining payments will be included in the payment schedule that was provided for the high pressure blower skid. The above breakdown
