Before the construction began on the Erickson Pontiac project began, I asked that
we might get together and discuss special inspections on that project. I again requested
the meeting in the letter that I sent you regarding plan review. John Bagley recently
informed me that the concrete inspections were not completed and that he would have
concrete cores drilled for testing if needed. You are the Engineer of Record on this
project and should be comfortable with the level of special inspection on this project. I
told Mr. Bagley that if you were willing to accept the inspection "as is" then we would
not require the cores to be drilled.
While Mr. Bagley was here he dropped off a letter to verify the bolt connection
inspections for the Erickson Pontiac job. Please find a copy of that letter attached to the
back of this document. I have a couple of questions regarding the letter. First, was Mr.
Lunden the person who acted as inspector during the bolt tightening? Next, are you
willing to accept the framing subcontractor as the inspector? The Specification for
Structural Joints Using ASTM A325 or A490 Bolts Section 9.2.1. titled Turn -of -the -nut
Pretensioning, states the following:
"The inspector shall observe the pre -installation verification testing required in
Section 8.2.1. Subsequently, it shall be ensured by routine observation that the
bolting crew properly rotates the turned element relative to the unturned element
by the amount specified in Table 8.2."
I have attached Section 8.2.1 and Table 8.2 to the back of this document. The
code itself does not specify who will do the inspections. The 1997 Uniform Building
Code UBC Section 1701.1 states that "the owner or the engineer or architect of record
acting as the owner's agent shall employ one or more special inspectors who shall
provide inspection during construction on the types of work listed under Section 1701.5".
Special inspection is under your charge. I informed Mr. Bagley that the Building
Department would accept the results of the bolt inspection if you the Engineer of Record
were willing to do so. Once again, you are the Engineer of Record on this project and
should be comfortable with the level of special inspection on this project.
Please let me know if you are accepting the letter as evidence of bolt inspection
and if you will be requiring core drilling for concrete inspection. If you have any
questions, please give me a call at 359-3020 ext. 324.
Sincerely,
Val Christensen

of adjacent bolts. The resulting reduction in total clamping force will reduce the
slip resistance.
In the case of hot -dip galvanized coatings, especially if the joint consists of
many plies of thickly coated material, relaxation of bolt pretension may be
significant and re-pretensioning of the bolts may be required subsequent to the
initial pretensioning. Munse (1967) showed that a loss of pretension of
approximately 6.5 percent occurred for galvanized plates and bolts due to
relaxation as compared with 2.5 percent for uncoated joints. This loss of bolt
pretension occurred in five days; loss recorded thereafter was negligible. Either
this loss can be allowed for in design or pretension may be brought back to the
prescribed level by re-pretensioning the bolts after an initial period of "settling -in".
As stated in the Guide, Kulak et al (1987; p. 61), "...it seems reasonable to
expect an increase in bolt force relaxation as the grip length is decreased.
Similarly, increasing the number of plies for a constant grip length might also lead
to an increase in bolt relaxation."
8.2.1. Turn -of -Nut Pretensioning: All bolts shall be installed in accordance with the
requirements in Section 8.1, with washers positioned as required in Section 6.2.
Subsequently, the nut or head rotation specified in Table 8.2 shall be applied to all
fastener assemblies in the joint, progressing systematically from the most rigid
part of the joint in a manner that will minimize relaxation of previously
pretensioned bolts. The part not turned by the wrench shall be prevented from
rotating during this operation.

Dear Scott,
I have reviewed the Erickson Pontiac drawings that you have provided me and
have identified the following discrepancies:
1. Provide driveway approach details as per the City of Rexburg Standard
Specifications.
2. Show area of road construction on 1500 West to be included in this
project. Change typical street cross section to identify 3" of asphalt over
4" of 1/4" crushed gravel over 20" of Granular Borrow (Pit Run).
3. Procure State of Idaho Highway Department permission for connection
into the State storm drain system.
4. Procure State of Idaho Highway Department permission for driveway
access on State Highway 33 (Main Street).
5. Provide better details for handicap parking and egress from parking lot
into building. Identify signs, asphalt painting, degree of slope, etc..
6. Provide Engineer's letter or new foundation plans that will accommodate
the changes in seismic from 2B to 3 and wind exposure from B to C.
7. Provide handicap access from showroom to Northern portion of building.
Please include details.
8. Change locker room so that it will be accessible to the handicapped.
9. Change parts room from B occupancy to S occupancy. Provide list of
items to be stored. If items do not fall under "low hazard storage criteria"
then provide separate room with 1 -hr. separation or storage cabinets that
are constructed and certified for storage of the materials that will not meet
the low hazard criteria.
10. Where sales counters and windows are provided provisions must be made
for the handicapped as per 1997 UBC Section 1105.4.4.3. Please provide
details.
11. Showroom floor, Service Department, Body shop and Paint Shop floors
must be constructed as per 1997 UBC Section 307.2.2.
12. Provide notes or details for firewall penetration by utilities.
13. If insulation is not covered by fire -restive material, provide notes requiring
surface to be flame spread rated at 25 or less.
14. Provide 1 -hr. separation around boiler if over 400,000 btu.
15. Provide mechanical notes and details which identify air exchange for
bathrooms as per 1997 UBC Section 1202.2.
16. Provide mechanical notes and details which identify venting for H-4 areas
as per 1997 UBC Section 1202.2.4.
17. Show details of firewall connection at bottom of roof sheathing.
18. Comply with Fire Department Requests as per the attached documents.
UBC Section 302.1 provides an exception for separation from spray
booths "when an approved spray booth constructed in accordance with the
Fire Code is installed".
Please let me know if there will be any problems making the above changes. If
you can get some assurance back to me that all of the above requirements can be met, we
can proceed with your building permit. In the future if we can try to have all the design
information to us prior to requesting plan review it would make the review process much
more efficient and therefore much more timely.
On another note, please get with me concerning special inspections, we usually
meet with the engineer or architect of record and talk about these before construction
start. Did the concrete contractor have cylinders and slumps taken? Also, we will need
to make sure that bolt and weld inspections are performed as per UBC Section 1701.
Let me know if I can be of any further assistance. If you have any questions,
please give me a call at 359-3020 ext. 314.

Dear John,
I still need some changes to be implemented with the following items on the Little
Gracie's Carwash drawings.
1. The structure's location with regard to the North property line requires that the end
wall be built to one hour fire -resistive standards and that the roof and ceiling be built
to same standard for a distance of 10 feet. See 1997 UBC Section 709.4.1 exception
# 5.1. Please provide a detail.
You responded with a Class "A" roofing material to be used as a covering over the
gable end as well as for the roof cover. Class "A" roofing material does not in
itself make up a Mr. firewall. If there is an application where the roofing could be
substituted for 1 hr. construction, I would need the manufacture's literature or an
ICBO evaluation report that identifies the use as such. I still need a detail showing
1 hr. construction for the wall and a portion of the roof.
2. City ordinance requires 10% of property to be dedicated to landscaped area. My
calculations show that you are about 350 square feet short.
Lot coverage is defined on page 8 of the zoning ordinance as "The area of a site
covered by buildings or roofed areas and impervious surfaces". On page 21 of the
ordinance, the maximum lot coverage is identified as 90%. Please add the
necessary additional landscaping.
If you have any questions I can be reached during the day at 359-3020 Ext. 314.

Dear Justin
I have finished the review on the Nextel equipment shelter located on the corner of Barney
Dairy Road and 3rd East in Rexburg Idaho. Everything looks satisfactory. You will need to
widen Barney Dairy Road, as well as provide curb, gutter and sidewalk around the entire lot.
Please provide me with two copies of site improvement drawings that show details of all
curb/gutter and sidewalk. You will also need to provide a drawing showing street construction,
including section and material details. Page T-1 of your plans has a vicinity map that clearly calls
out the building location on a piece of property located on the other, side of town.
As soon as I receive the new drawings, I will finish your review. If you have any
questions please give me a call at 359-3020 ext. 324 (new extension#).

Dear Scott,
Before the construction began on the Erickson Pontiac project began, I asked that
we might get together and discuss special inspections on that project. I again requested
the meeting in the letter that I sent you regarding plan review. John Bagley recently
informed me that the concrete inspections were not completed and that he would have
concrete cores drilled for testing if needed. You are the Engineer of Record on this
project and should be comfortable with the level of special inspection on this project. I
told Mr. Bagley that if you were willing to accept the inspection "as is" then we would
not require the cores to be drilled.
While Mr. Bagley was here he dropped off a letter to verify the bolt connection
inspections for the Erickson Pontiac job. Please find a copy of that letter attached to the
back of this document. I have a couple of questions regarding the letter. First, was Mr.
Lunden the person who acted as inspector during the bolt tightening? Next, are you
willing to accept the framing subcontractor as the inspector? The Specification for
Structural Joints Using ASTM A325 or A490 Bolts Section 9.2.1. titled Turn -of -the -nut
Pretensioning, states the following: ,
"The inspector shall observe the pre -installation verification testing required in
Section 8.2.1. Subsequently, it shall be ensured by routine observation that the
bolting crew properly rotates the turned element relative to the unturned element
by the amount specified in Table 8.22'
I have attached Section 8.2.1 and Table 8.2 to the back of this document. The
code itself does not specify who will do the inspections. The 1997 Uniform Building
Code UBC Section 1701.1 states that "the owner or the engineer or architect of record
acting as the owner's agent shall employ one or more special inspectors who shall
provide inspection during construction on the types of work listed under Section 1701.5".
Special inspection is under your charge. I informed Mr. Bagley that the Building
Department would accept the results of the bolt inspection if you the Engineer of Record
were willing to do so. Once again, you are the Engineer of Record on this project and
should be comfortable with the level of special inspection on this project.
Please let me know if you are accepting the letter as evidence of bolt inspection
and if you will be requiring core drilling for concrete inspection. If you have any
questions, please give me a call at 359-3020 ext. 324.

Val Christensen

En
of adjacent bolts. The resulting reduction in total clamping force will reduce the
slip resistance.
In the case of hot -dip galvanized coatings, especially if the joint consists of
many plies of thickly coated material, relaxation of bolt pretension may be
significant and re-pretensioning of the bolts may be required subsequent to the
initial pretensioning. Manse (1967) showed that a loss of pretension of
approximately 6.5 percent occurred for galvanized plates and bolts due to
relaxation as compared with 2.5 percent for uncoated joints. This loss of bolt
pretension occurredin five days; loss recorded thereafter was negligible. Either
this loss can be allowed for in design or pretension may be brought back to the
prescribed level by re-pretensioning the bolts after an initial period of "settling -in".
As stated in the Guide, Kulak et al (1987; p. 61), "...it seems reasonable to,
expect an increase in bolt force relaxation as the grip length is decreased.
Similarly, increasing the number of plies for a constant grip length might also lead
to an increase in bolt relaxation."
8.2.1. Tum -of -Nut Pretensioning: All bolts shall be installed in accordance with the
requirements in Section 8.1, with washers positioned as required in Section 6.2.
Subsequently, the nut or head rotation specified in Table 8.2 shall be applied to all
fastener assemblies in the joint, progressing systematically from the most rigid
part of the joint in a manner that will minimize relaxation of previously
pretensioned bolts. The part not turned by the wrench shall be prevented from
rotating during this operation.

Subject: Special Inspections for Erickson Pontiac GMC New Facility
Dear John,
I'm sure that by now you have received your copy of the City's letter dated 9/5/01 regarding Special
Inspections. You may even be in the process of addressing the City's concerns.
After reading the letter on bolt tightening provided by Teton West to the City I share their concerns about
whether or not Mr. Lunden has the qualifications and physically inspected the building. This concern is
based primarily on Mr. Lunden's title - "Business Development Manager". The 1997 Uniform Building
Code says this about Special Inspectors: "Section 1701.2 Special Inspector. The special inspector shall
be a qualified person who shall demonstrate competence, to the satisfaction of the building official, for
inspection of the particular type of construction or operation requiring special inspection. " At this point
in time I will accept a valid inspection done by Varco Pruden though it is preferable, both by the code and
standard practice to have an independent company do the inspection.
The City will not give a Certificate of Occupancy without the approval of the Engineer of Record which I
am. 1 am unwilling- to accept the liability for either the steel building or the concrete since you were made
aware of both special inspection requirements in plenty of time to have the inspections done.
Please provide the following:
• A letter from your foundation engineer accepting responsibility and liability for the quality and
strength of the concrete in the foundations and floor slab.
• A letter from Mr. Gene Lunden stating that he is qualified to do the special inspection referred to
in his letter dated August 28, 2001 and that he personally performed the inspection in accordance
with the requirements of thel997 Uniform Building Code Section 1701.6 High Strength Bolting as
quoted below:
"The inspection of high-strength A 325 and A 490 bolts shall be in accordance with approved
nationally recognized standards and the requirements of this section:
While the work is in progress, the special inspector shall determine that the requirements for
bolts, nuts, washers and paint; bolted parts; and installation and tightening in such standards are
met. Such inspections may be performed on aperiodic basis in accordance with the requirements
of Section1701.6. The special inspector shall observe the calibration procedures when such
procedures are required by the plans or specifications and shall monitor the installation of bolts
to determine that all plies of connected materials have been drawn together and that the selected
procedure is properly used to tighten all bolts. "
If it turns out that some other individual from Varco Pruden did the physical inspection a letter
will be required from that person.
Please call me if you have any questions.

Dear Scott,
I have reviewed the Erickson Pontiac drawings that you have provided me and
have identified the following discrepancies:
I . Provide driveway approach details as per the City of Rexburg Standard
Specifications.
2. Show area of road construction on 1500 West to be included in this
project. Change typical street cross section to identify 3" of asphalt over
4" of V crushed gravel over 20" of Granular Borrow (Pit Run).
3. Procure State of Idaho Highway Department permission for connection
into the State storm drain system.
4. Procure State of Idaho Highway Department permission for driveway
access on State Highway 33 (Main Street).
5. Provide better details for handicap parking and egress from parking lot
into building. Identify signs, asphalt painting, degree of slope, etc..
6. Provide Engineer's letter or new foundation plans that will accommodate
the changes in seismic from 2B to 3 and wind exposure from B to C.
7. Provide handicap access from showroom to Northern portion of building.
Please include details.
8. Change locker room so that it will be accessible to the handicapped.
9. Change parts room from B occupancy to S occupancy. Provide list of
items to be stored. If items do not fall under "low hazard storage criteria"
then provide separate room with 1 -hr. separation or storage cabinets that
are constructed and certified for storage of the materials that will not meet
the low hazard criteria.
10. Where sales counters and windows are provided provisions must be made
for the handicapped as per 1997 UBC Section 1105.4.4.3. Please provide
details.
11. Showroom floor, Service Department, Body shop and Paint Shop floors
must be constructed as per 1997 UBC Section 307.2.2.
12. Provide notes or details for firewall penetration by utilities.
13. If insulation is not covered by fire -restive material, provide notes requiring
surface to be flame spread rated at 25 or less.
14. Provide 1 -hr. separation around boiler if over 400,000 btu.
15. Provide mechanical notes and details which identify air exchange for
bathrooms as per 1997 UBC Section 1202.2.
16. Provide mechanical notes and details which identify venting for H-4 areas
as per 1997 UBC Section 1202.2.4.
17. Show details of firewall connection at bottom of roof sheathing.
18. Comply with Fire Department Requests as per the attached documents.
UBC Section 302.1 provides an exception for separation from spray
booths `when anapproved spray booth constructed in accordance with the
Fire Code is installed".
Please let me know if there will be any problems making the above changes. If
you can get some assurance back to me that all of the above requirements can be met, we
can proceed with your building permit. In the future if we can try to have all the design
information to us prior to requesting plan review it would make the review process much
more efficient and therefore much more timely.
On another note, please get with me concerning special inspections, we usually
meet with the engineer or architect of record and talk about these before construction
start. Did the concrete contractor have cylinders and slumps taken? Also, we will need
to make sure that bolt and weld inspections are performed as per UBC Section 1701.
Let me know if I can be of any further assistance. If you have any questions,
please give me a call at 359-3020 ext. 314.
