1.  PERMIT STATUS

reviewed. Comments issued.

2.  Advisory Comment: This review is based on
the requirements of the 2012 Anchorage Administrative Code (AMC 23.10), 2012
Grading, Excavation and Fill Code (AMC 23.105), 2012 International Building
Code (IBC), and all adopted references thereto as amended by MOA. The following
comments must be addressed before a permit can be issued. The approval of plans
and specifications does not permit the violation of the codes, or any federal,
state or local regulations.

Please submit a
written explanation for how each comment has been addressed.

3.  Advisory Comment: 

FILL OVER PEAT

Most of this project appears to be upgrades to the Dimond
Center parking lots.  I assume that the
traffic lanes are also part of the parking lot. 
All of the parking lot work appears to be placing fill over organics.  This is specifically allowed by AMC
23.105.108.2.1.

4.  Advisory Comment: 

GEOTECHNICAL REPORT
RECOMMENDATIONS

It is not clear on the drawings that the geotechnical
engineer’s recommendations have been followed. 
It appeared to me that the structural sections recommended in the report
need to be placed 100% under new traffic lanes with transition and keying into
existing fill sections beyond the footprint of the new traffic lane.  This does not seem to be the case in details
1 and 3 on Sheet 10 and detail 1 on Sheet 11. 
For example in detail 3 the 1:1 transition seems to be entirely within
the lane footprint.  There is very little
of the full section under the traffic lane.

You may want to have the geotechnical engineer review the
drawings to verify his intent was followed.

5.  SPECIAL INSPECTION
REQUIRED?

Soils special inspection is
required when the combined quantities of excavation and fill exceed 5,000 cubic
yards.  Please provide the quantities of
excavation and fill.  If the combined
quantities exceed 5,000 yards then please respond to comments 6-8.

6.  STATEMENT OF SPECIAL INSPECTION

If this work has combined quantities of excavation and fill
greater than 5,000 cubic yards, it is classified as Engineered Grading which
requires Special Inspection.  See AMC
23.105.105 and 23.105.106.2.

Please provide a Statement of Special Inspection detailing
the special inspector’s responsibilities as per IBC Table 1705.6.  Please show IBC Table 1705.6 on the
drawings.  Attach a copy of this
table to the Special Inspection and Testing Agreement before it is
signed.  See comment below.

7.  LETTER INDICATING WHO IS HIRING THE SPECIAL
INPECTOR

Provide a letter from the owner stating who he is
hiring to do the special inspection.  See
IBC, 1704.2, paragraph 1.  Only the owner
or a design professional acting for the owner can hire the special inspector.

8.  SPECIAL INSPECTION AND TESTING AGREEMENT

Please fill out and submit a signed copy of the Special
Inspection and Testing Agreement.  The
Statement of Special Inspection (with IBC Table 1705.6) needs to be attached to
this agreement before it is signed.  The purpose of this agreement is so that all
who are involved in the project know the extent of the special inspection.  This agreement can be found beginning on page
7 of the Special Inspection Program Requirements http://www.muni.org/Departments/OCPD/development/BSD/BSDDocuments/SpecialInspectionGuidelines.pdf
