We received an updated survey dated for the 9'4" retaining wall. Please review and provide comments.
Below is the chain of emails between me and the builder for your reference.
Thank you.

M i ke,
Your site pian has changed. A retaining wall was constructed without approval. The new wall is in a different location
than the two previously approved retaining walls. We need an updated site plan to review.

Mike,
Thank you for the specs for the concrete retaining wall. Our building official has reviewed and approved it. You may
proceed with framing.
Due to the change in the retaining walls, please provided us with a revised grading plan by Monday,June 29, 2015.
Don't hesitate to contact me if you have any questions.

M i ke,
Thanks for the additional information. The newly poured retaining wall is 9'4" in height. Since this is a new wall and is
over 4 feet in height and was not shown on the approved pian, we must receive the specs/engineering plan for the
construction of the wall before you can being to frame.
Thank you.

Mike,
After speaking with you this morning and consulting with my coworkers, in addition to having the surveyor show the top
of foundation transition points, please also have them show top and bottom of wall elevations for the new retaining wall
shown. We will need the above to approve the foundation as-built; before you may begin to frame.
In the near future, please provide us with a revised grading plan due to the change in the number of retaining walls and
the location for our review and approval.
Thank you.

2013 Standarclized Concrete Foundation Dra�win�s
Scope of Work:
These drawings apply to the construction of cast-in-place concrete foundation walls for typical residential cases.
These drawings are not to scale and all conditions are to be verified by the contractor. Means and methods of
construction for shoring,water-proofing, insulation,flashing, control and construction joints, and all other non-
structural requirements are to be by others in accordance with the Code and standard industry practice. These
drawings are valid until the end of 2013.
The drawings are to only be used by the contractor noted betow or his authorized sub-contractorslclients. These

enera o es:
1. Wall thicknesses noted are nominal unless specifically stated otherwise. Maximum tolerance is 112".
2. Maximum wall to footing centerline offset is 2". A minimum of 2"of footing is to extend on each side of the wall.
3. Place matching hooks around all wall corners and intersections for each horizontal bar.
4. Horizontal bars may be placed anywhere within the wall thickness provided 2"minimum cover is provided.
5. Bar laps when required are to be at least 32 diameters for grade 40 bars and 48 diameters for grade 60 bars.
6. Allowable bar placement tolerance is 112". Tying is not required if tolerances are met and maintained.
7. Dowels may be drilled and installed after footing pour unless otherwise noted. Vertical bars may be embedded
into footing in place of dowels at the same embedment. Vertical bars and dowels do not need to align. Dowels
may be bent down for safety and covering then bent back before wall placement.
8. Sill plate sections require at least two anchors with one within 4"to 12"of each end and at all corners and
intersections. Walls less than 24" in length require only one anchor.
9. Anchor bolts 1/2"or larger in diameter do not require corrosion protection per IRC section R319.3 exception 1.
10. Anchor bolts may be substituted with 1l2"diameter threaded rod epoxy grouted at same spacing with 7"embed.
11. The presence of form oil on the reinforcing is acceptable for the conditions contained in these drawings.
12. Slope grade 6"minimum downward away from foundations within first 10 feet or provide Code adequate swale.
13. Do not backfill until the concrete has reached at least 70 percent of the 28 day concrete strength. Use of
adequate shoring is required when the final floor and slab systems are not in place.
Cold Weather Guidelines:
The following information is considered to be general guidelines for the placement of concrete in cold weather
conditions. It is the contractor's responsibility to ensure proper means and methods are followed and that the final
in place product is adequate.
1. The contractor is to work with the concrete supplier to obtain a mix design which accounts for the conditions
expected. Use of extra cement, early-strength concrete,and accelerators are recommended at temperatures
below 20 degrees F.
2. Concrete is to be delivered to the site in a timely manner.
3. Placement of concrete earlier in the day to take advantage of latent heat of sunlight is adviced.
4. Do not add additional water. Using water-reducing admixtures is recommended when required.
5. Forms are to be free of snow and ice. Do not place concrete in contact with frozen ground ,snow,or ice.
6. Preheating of rebar is not required, however it is to be free of frost, snow,and ice.
7. Use of form blankets or other approved protection is highly recommended for the top of the wall at temperatures
below 10 de rees F and for the whole wall when below zero degrees F.
