COST ESTIMATES

The cost estimates contained in this presentation and in the executive summary report are based upon the following factors:

Cost estimates are construction costs only No general condition fees, A/E fees, or other fees

are included Costs are based on 2009 costs with no yearly

escalation

CHILLED AND CONDENSER WATER SYSTEMLOAD & CAPACITY

• 730 Tons – Original Load

• 800 Tons – Original Capacity

• Original chilled water system

consisted of two 400 ton Trane units with condenser water provided by

groundwater wells.

• 1346 Tons – Present Load

844 – Main Building

77 – CRC

224 – Welcome Center

• 1200 Tons – Present Capacity

89% diversity factor

ORIGINAL PRESENT

However, the piping configuration with two chillers in series and one in parallel does not appear to allow the total capacity to be utilized.

Current Drawings do not reflect the field installation of this system.

Estimated Cost ~ $2,000,000 2014 - 2019

HEATING HOT WATER SYSTEMS LOAD & CAPACITY

• Original heating hot water load for the main building was approx. 5,245 MBH.

• The presently installed and original heat exchanger is sized to deliver 5,500 MBH.

• The current heating load is approx. 8,112 MBH: Main building plus the

CRC,

Welcome Center, and

Grand Ballroom additions

68% diversity factor

very low system is undersized.

ORIGINAL PRESENT

Estimated Cost ~ $300,000 2010

STEAM - CONDENSATE SYSTEMS LOAD & CAPACITY

EMC has the steam load on this branch as 8,112 MBH for the heat exchanger, 1,550 MBH for both domestic water heaters, 608 MBH for AHU-B-4 and 1,115MBH for AHU-B-5.

This gives a total steam load for this branch of 11,385 MBH or approx. 11,385 lbs per hour.

The pressure reducing valve associated with this branch is indicated per the 1967 documents as 8,000 lbs per hour.

a diversity of 70%. This is a very low diversity factor and indicates the system is undersized.

The present steam pressure reducing valve configuration is a single pressure reducing valve with a manual bypass. For a building of this size, typically a 1/3 pressure reducing valve, a 2/3 pressure reducing valve and a manual bypass are installed. Thus, under part-load conditions, the 1/3 valve would handle the steam load and under full-load conditions the 2/3 valve would open to increase steam flow.

This configuration provides a finer degree of control.
