Pidgeon Manure/Infestation

[Guest guest]

I've just been asked to bid on a remediation project in a 6-story

building. The job has 5 floors containing a lot of pigeon manure,

and carcasses in varying degrees of decay. The top floor, the " hot-

spot " has pigeon manure about 8-12 inches deep in an area

approximately 2000 SF. Each floor thereafter is 2000 SF but not as

contaminated as the hot spot...but still has a lot of manure.

Additionally, large rat droppings were observed during the

inspection.

There is an open elevator shaft with pigeon manure on all sides. The

elevator is inoperable; the car is in the basement. It appears the

pigeons came in through the eaves of the roof then used the elevator

shaft to go to various floors.

Some of my concerns are that this building is 150 years old--

gorgeous n building. Has not been occupied for 20 years, and

the new owner has owned the building for approximately 3 years. The

owner is in litigation with the prior owner on faulty new roofing

and new windows that leak.

The walls are plaster and lath, which may contain asbestos. The

peeling paint on the walls probably contains lead...and there is 9 "

tile on the floor, which may contain asbestos. There is manure on

bare wooden floors, concrete floors and tiled over floors.

The client was specific with the scope of work:

1. Remove the pigeons. 2. Keep them out. 3. Clean up the premises to

make it safe for a demolition crew to gut the structure. The cost of

this job is to be separate from addressing the lead paint and

asbestos abatement.

It's really a catch 22.

In order to remove the manure starting at the hot spot, I must wet

the manure, then shovel up the manure into bags. I believe this

would be classified as bio waste material. Then I would have to

scrub the walls and the floors. When scrubbing the walls I'm going

to be faced with disturbing lead based paint.

Should I recommend to the client that a CIH should be involved to

write a protocol?

What can I expect from an inspection/assesment from a CIH?

In order to clean the elevator shaft I am wondering if I could use a

pressure washer to wash the walls after applying a disinfectant?

Could I then wash the elevator shaft all the way down with final

cleanup on the shaft floor?

I know I need air scrubbers and because there is no working elevator

this would be considered a heavy-duty work area.

Any suggestions on how to proceed?

How clean is clean for an unoccupied building where eventually most

of the non-load-bearing walls will be removed?
