Project Team• UCI

– Matt Gudorf Project Manager– Don Gaw Manager Project Services– Jim Hay AVC Facilities

• Engineer– Goss Engineering

• Lucas Hymann• Hanming Xu

• Contractor– Alpha Mechanical

What Will Be Done •Replacement of

•Supply Fans•Coils•Hot and Chilled Water Piping•Condensate Pans and Drain Lines

•Repair of•The interior and exterior of the Air Handler

•Installation of● VFD drives● Automated Valves● Deep Pocket Filters

Why•Simply the units have deteriorated

•Extensive rust•Fan motors no longer mechanically serviceable •Leaking coils

•Risk Avoidance•Scheduled Replacement will be much shorter and a comprehensive plan can be developed.•Emergency Repairs will take longer, leave us open to further failures and provide no time to plan.

Rusted Exhaust Fans

Leaking Coils

It’s just old!

When

–Best time of year for temperature

–Fewest number of people on campus

–Better access for contractors crews means faster work

Help Us Help You

• Turn off– Computers, Printers, Copy Machines, Personal

Refrigerators• Combine

– If it has to remain in operation please make sure its 100% full

• Take advantage of other space– Ask for hood and storage space in other buildings BioSci

will work with you!• Work with EH&S

– Free chemical disposal to clear out those fume hoods• Let us know

– No one wants lost research or equipment so please work to let us know so we can help meet your needs.

Building Security

• If you see something out of the ordinary question it!

• Contractors will be working in the Mechanical rooms facing the new Bio Sci 3 building and ring mall these rooms are located in the basement.

• UCI staff carry ID and trades support wear blue shirts with their trade and name on their shirt

Adapting to your input!

In an effort to address the concerns raised by members of the Bio Sci community Facilities has met with EH&S, Goss Engineering, and Bio Sci Facilities to develop two plans to present today.

PLAN – A• The building would be completely shut

down during the construction • The work would be compressed into the

minimal amount of time required by writing contract requirements that the contractor work multiple shifts in multiple locations. This would impose the shortest disruption to the building occupants.

What to Expect (Plan A)

There will not be• Supply Air

– Stuffy, and stale air– Air changes will be

noticeably less frequent

• Exhaust Air– Minimal exhaust– No fume hoods

• Extensive noise, hammering, or vibration

There will be–Electricity–Water

–Domestic–Chilled

–Building Access

PLAN – B• The construction would be phased

working on one air handler and then the other.

• The work would no longer be compressed and we anticipate a schedule of 12 to 14 weeks to complete the required work.

What to Expect (Plan B)

There will not be• Constantan supply air

– One half of the building at a time.

– Air will move from high to low

• Exhaust Air– Minimal exhaust on half the

building at a time

• Extensive noise, hammering, or vibration

There will be–Electricity–Water

–Building Access–Fume Hoods

Plan B

Spot Cooling

• Prioritize because these do produce heat load we have to keep the spot cooling to a minimum

• Should an emergency arise we will have units for spot cooling in reserve.

• Move and Cools will be used in both plan A and B however in plan B they are less critical and more can be implemented if needed

Stocking up on provisions

Do you use dry ice or liquid nitrogen?

We encourage you to order extra for your department. We will work with the Bio Sci Facilities staff to cover the added expense.

Just in case!

An empty -80 freezer will be set up in the loading dock area. Should a crisis arise it will be ready for you.

The Dry RunPlan A

Wed. November 28th8am – 12pm Shut off both air handlers and most building exhaust and monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached.

Plan B

Wed. November 28th8am – 12pm Shutdown air handler 1 and lower the exhaust flow as shown in the phasing diagram. monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached. 12pm-4pm Shutdown air handler 3 and lower the exhaust flow as shown in the phasing diagram. monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached.
