RE: Re-Certification of Pad Grade for Lot 1-Hotel 2 - Basement Level, as shown on
Architectural Plan Sheet A3 Basement Plan per Nogle Onufer Associates Architects and the City
of Carlsbad Drawing No. 428-9B, Project No. CT 03-02, Grading Plans for Carlsbad Ranch,
Planning Area No. 5, Resort Site - Hotel 2 - Phase 1, said plan mylars are at the City of Carlsbad
for final signatures.
To whom it my concern,
Excel Engineering performed a field survey on January 10, 2007 to confirm the rough grade pad
for the reference site and a Rough Grade Pad Certification letter was issued on January 11, 2007.
The elevations were based on Architectural Plan Sheet A3 Basement Plan provided by Nogle
Onufer Associates Architects on November 7, 2006. The rough grade pad was found to be as
follows:
Pad Pad Elevations F.F. Design Elevation
Hotel 2 Basement Level varies: 222.97 - 224.34 varies: 223.20 - 225.00
Between January 10, 2007 and March 14, 2007 the reference site was disturbed, a re-certification
was completed. Representatives from Excel Engineering performed a field inspection on March
14, 2007. The pad failed and was re-staked at that time. Excel Engineering performed a second
field survey on March 16, 2007 to re-certify and confirm the grade pad for the referenced site. A
maximum of 16 shots was taken. The finished pad grade is as follows:
Pad Pad Elevations F.F. Design Elevation
Hotel 2 Basement Level varies: 222.99 - 224.42 varies: 223.20 - 225.00
The area being re-certified hereon is the building area of the pad at the basement floor elevation
as shown on said Architectural Plan Sheet A3; elevations vary and the foundation is a 7" section
as directed by the site superintendent.
The maximum deviation from the bottom of said 7" section to finish pad for the basement was
found to be 0.1'. Therefore the pad is in substantial conformance with the Basement Plan by
Nogle Onufer Associates Architects, a copy of which is attached.
If you have any further questions or need any additional information do not hesitate to call.
