Re: Load Analysis of Existing Mezzanine - Temporary Eagan Library at Eagan Civic Center
3850 Pilot Knob Road, Eagan, MN 55122
KOMA No. 008230
Dear Mr. Burrows:
At your request, this office has structurally reviewed the above noted mezzanine. The purpose of the
review was to determine if the mezzanine would be capable of supporting a temporazy library layout.
No other areas of the building were reviewed at this time. Documents available for review included:
• Drawings prepared by RKK Structural Engineering numbered S 1 through SS and dated 12/19/94.
• Mezzanine build-out drawings prepared by Leo A Daly numbered T1.00, A1.01, A1.02 and
dated 5/12/08.
• Fabcon precast concrete shop drawings numbered 1 through 5 and dated 3/17/95.
• Library floor plan supplied by Dakota County. See attached.
The existing mezzanine structure will be capable of supporting the temporary library layout per your
attached floor plan. Deviations from the referenced plan should be reviewed by this office. Also, the
allowable live load for the mezzanine is 100 ps£ For reference, 125 psf is defined as light storage. The
100 psf loading criteria should be posted according to Section 16033 of the state building code. See
attached.
The information and opinions contained herein are based upon the limited investigation described at the
beginning of this report. No warranties are expressed or implied regarding the existence of other
unknown conditions not specifically addressed. Our work is in accordance with generally accepted
engineering standards and is not intended to be relied upon or transferred to individuals other than the
addressee. Should information or conditions become known which differ from the discussion herein,
they may alter the opinions or conclusions of the undersigned.
If you should have any questions or require further information, please call.

The Building Codes do not cover all simations. Ofcen the Firm's interpretation of the code is different than the local building official's interpretaqon. The
building official is required to issue interpretations of the code. The interpretation process can be subjective and tends to be dynamic as the Fim and the
building official diswss [he public health, safety and wetfare issues involved. Often the Stace is asked to provide an in[e[pretation which the local building
officiat oonsidus the `o%cial ruling°. It is nol possible m predict ihe amount oftime requiceA to rasolve code issues requiring interpretefioq artd as such,
