Osprey Assessments Proposal No: 15.01.0006.01

Dear Mr. Harney,

On behalf of Osprey Assessments LLC (Osprey), we are pleased to present this proposal to

perform an UAV Aerial Visual Façade Survey on the façades of the subject building referenced

above. The purpose of the UAV Aerial Visual Façade Survey is to provide images of sufficient

resolution and clarity of the façade that your organization can include in your assessments of

the existing façade, window, flashings and other building envelope components for the purpose

of developing a business plan for the maintenance, management and capital planning of the

façade building envelope assets. This proposal includes a brief description of the project, our

proposed scope of work, fee, schedule, and authorization procedures. We appreciate this

opportunity to propose our services.

PROJECT BACKGROUND

The project information about this proposal was obtained during a meeting with Messrs. Richard

Monocchio, James Harney, John Duncan and Asif Rahman of the Housing Authority of Cook

County (HACC), and Messrs. Gordon Dowrey and Josh Kneifel of Osprey Assessments LLC in the

Authority’s main office at 175 W. Jackson Blvd., Chicago, IL on July 23, 2015. Additional asbuilt drawings were provided via email at a later date. Turlington West Apartments consists of

a 14-story, 150 unit, mid-rise apartment tower with an approximately 6,883 S.F. connected

single story community building situated on an approximately 1.43 acre site in Harvey, Illinois. 

It is bounded on the north by the Harvey Fire Department Station 3, the east by Robey Avenue,

the south by a single family residential area and the west by a brownfield site formerly known

as Dixie Square Mall. The tower appears to be concrete framed. The building façade consists

of a brick veneer and concrete block curtain wall system supported at each floor by steel angles

attached to the building structure. In the apartment tower aluminum framed windows are

installed in set-backs in the facade system. Additional façade penetrations are provided for

thru wall A/C sleeves and units.
