Re: Horizons Parkway Development - Kiosk
Dear Mr. Hoover;
HDR staff has reviewed the construction drawings, Sheets Al and A2, prepared by Nearing
Staats Prelogar & Jones (NSPJ) Architects dated September 28, 2012 for the referenced
project. This review was completed at the City's request to determine if the reinforced
concrete pedestal and foundation conform to structural engineering requirements in the City
Building Code (IBC 2012) and ACI standards referenced by the Building Code. The structure
has been reviewed as a non - building structure classified as a Group U (Utility and
Miscellaneous) structure (IBC 312).
General Comments
1. Calculations showing conformance of the structural design to IBC Chapter 16 should
be submitted.
2. Both drawings request a "bid alternate" to construct the kiosk as a "precast structure
on foundation as shown ". If a precast structure is to be used then loads, performance
requirements, and strength and serviceability requirements must be given for the
precast connections at the foundation and top slab. The design drawings for the
precast concrete should then be submitted to the City for review or identified as a
deferred design submittal that will be made later.
3. The structure does not have any access to the interior of the kiosk for inspection in
the future. Access similar to the requirement of IBC Section 1209 should be provided,
or other means of inspecting the interior should be identified.
Sheets Al and A2
1. Identify classification and type of construction.
2. The Basic Wind Speed listed in General Requirements Note B is not consistent
with IBC 2012. Confirm that provisions of IBC Section 1609 have been met, and
that the higher localized wind pressure for components and cladding has been
considered.

Suite 1000 Fax (8161360 -2777
Kansas City. M064111.1856 wwwhdrinc com
3. Show the soil bearing and lateral resistance values used in design.
4. The quantity of horizontal and vertical reinforcement in the pedestal walls is
insufficient to meet the requirements of ACI 318 Chapter 14, as referenced by IBC
Chapter 19.
5. The quantity of dowel reinforcement in the footings is insufficient to meet the
requirements of ACI 318 Chapter 15, as referenced by IBC Chapter 19.
6. Cold- Formed Note D is not consistent with the girt material gauge shown in the
details. The "weld strength" values shown are actually yield strength values for
cold- formed members. The attachment of the cold formed girts to the steel
frame has not been detailed in Detail 2/A2. Show the fasteners to be used to
attach the girts.
7. The connections of the hot - rolled steel frame angles have not been detailed or
described. Show connection details conforming to IBC Section 2204 and IBC
Section 1909, particularly at the anchorage of the steel frame to the concrete
base.
8. Confirm that the 7/16" sheathing has adequate load capacity for the correct
design pressures in accordance with IBC Chapter 23.
9. Show details or performance requirements for attachment of the "cast stone"
finished foam trim to the concrete.
Please contact us if you have any questions about these comments or if we can be of further
assistance.

Riverside, MO ‘
Comments: The following are written responses to the HDR Engineering's comments as
representative for the City of Riverside, dated 4/29/2013
General Comments
1) Structural engineering calculations are attached.
2) No response..
3) No response.
Sheets Al and A2
1) No response.
2) 90 mph wind speed is consistent with Codes in effect at the time of the original
design (2006 IBC and 2005 ASCE /SEI 7). A lateral wind load of 20 psf (for "other
structures" #6.5.15) was applied over the projected area of the obelisk using a
uniform 6 ft width for the top section and a uniform width of 8' -6" for the bottom.
Component and cladding loads are not considered applicable to the structural
design of a non - building structure.
3) The presumptive soil bearing of 1,500 psf is used for foundation design.
Passive /lateral soil resistance of 300 pcf (equivalent fluid) is assumed.
4) I disagree, ACI 318 -05 #14.2.7 allows waiver of thickness and reinforcement
requirements where adequate strength and stability are provided. By empirical
analysis, the stress ratio for axial load is less than 10%.
5) I disagree, see response for item 4 above. The detailing is consistent with
continuation of vertical wall reinforcement into the footing.
6) The gins used are 20 ga cold- formed material. Welding is not recommended.
My preference is for the installing contractor to submit proposed connections for
review by architect /engineer.
•
7) Connections for the steel frame will be reviewed and accepted with the shop
drawing submittal. My expectation is that all steel frame connections will be
welded.
8) As roof sheathing, 7/16" span -rated 24/16 sheathing can withstand 50 psf total
load or 40 psf live load for the 24 inch span. The sheathing is screw- attached at 6"
oc at all panel edges and 12" oc at all other supports.
9) No response.

O A. The following list constitutes a comprehensive list of Tuscan Stoneworx tested and approved substrates or
mediums for which Tuscan Cast Stone may be applied.
1. Properly prepared EIFS
2. Properly prepared Natural Stucco
3. Concrete
4. Properly prepared Masonry Brick, Block & Stone
O 5. Property prepared Cement Board
6. Properly prepared Sealed Gypsum Board(drywall/ DensGlass)
B. If substrate is other than one listed on Tuscan Cast Stone manufacturers List of Approved Substrates,
consult with the Tuscan Cast Stone manufacturer for installation procedures and adhesives.
C. Check dimensions of substrate surfaces (length, width, height, radiuses, angles, etc.) and openings to insure
that supporting wall surface, as built, will accept the Tuscan Cast Stone pieces as manufactured.
D. Inspect Tuscan Cast Stone pieces as delivered to insure that all the profiles, length, colors and finishes that
are needed to install all the Tuscan Cast Stone are on hand.
E. Insped surfaces for.
1. Contamination — algae, chalkiness, dirt, dust, efflorescence, form oil, fungus, grease, laitance, mildew or
other foreign substances.
Cip 2. Surface absorption and chalkiness.
3. Cracks — measure crack width and record location of cracks.
E—' Instructions
4. Damage and deterioration.
5. Moisture content and moisture damage — use a moisture meter to determine if the surface is dry enough
to receive the Tuscan Cast Stone and record any areas of moisture damage.
6. Compliance with specification tolerances — record areas that are out of tolerance (greater than' inch in
8-0 feet [6mm in 2438 mm] deviation in plane).
F. Inspect sheathing application for compliance with applicable requirement:
1. [Exterior gypsum sheathing —GA -253]'
2. [Exterior Grade and Exposure I wood based sheathing - -APA Engineered Wood Association E 301*
3. [Glass mat faced gypsum sheathing — Georgia Pacific Publication 101514]
4. [Proprietary cementitious sheathing - Consult manufacturers published recommendations]
G. Report deviations from the requirements of project specifications or other conditions that might adversely
affect the Tuscan Cast Stone installation to the General Contractor. Do not start work until deviations are
corrected.
2. SUBSTRATE PREPARATION
A. [Remove surface contaminants on concrete and concrete masonry surfaces, such a form release oils, dust,
paint, waterproofing, etc.]
B. [Apply conditioner to substrate by sprayer or roller to chalking or excessively absorptive surfaces.]
C. [Replace weather - damaged sheathing and /or framing.]
D. Repair damaged or cracked surfaces.
E. Level surfaces to comply with required tolerances in this specification.
3. INSTALLATION
(Note: the coordination of work with other trades is important for the performance of the wall assembly, in particular the
installation of flashing above window and door heads, beneath window and door sills, atroof/wall intersections, decks,
intersections of lower walls with higher walls, projecting features, and at the base of the wall to ensure that where water
is likely to penetrate the wall assembly, it will be drained to the exterior at the source of the leak).
Weather conditions affect application and drying time. Hot or dry conditions limit working time and accelerate drying.
Adjustments in the scheduling of work may be required to achieve desired results; cool or damp conditions extend
working time and retard drying and may require added measures of protection against wind, dust, dirt, rain and
freezing. Adjust work schedule and provide protection.
4. INSTALLING TUSCAN CAST STONE PIECES
2 A. General
1. Install one Tuscan Cast Stone piece at a time, next to the most recently installed piece.
2. If multiple courses of Tuscan Cast Stone are to be installed, work from the bottom up.
3. Follow architects drawings and Tuscan Cast Stone manufacturer's drawings for location of pieces and
joints.
4. Do not add any other materials to the adhesive mixture. Prohibited additional materials include rapid
0 binders, anti- freeze, resins, pigments, sand, lime, aggregates, minerals, extenders, more than 1 cup
E total of water, etc.
5. Compare the dimensions of each Tuscan Cast Stone piece to be installed in a specific location to see if
t 2) it will fit, prior to applying the adhesive and attaching the piece to the substrate.
6. If the piece is too long, or if a precision fit is required (no Tuscan Grout joints) trim the Tuscan Cast
Stone piece using a masonry or diamond saw, or by diamond grinding.
B. Preparation of Attachment Adhesive
1. Use an acrylic polymer base mixed with Portland Cement such as Dryvit Systems Inc. Primus adhesive
or equivalent. Make only enough attachment adhesive at one lime that can be used for the size of the
wall area being built, and before the adhesive starts to set.
2. Follow approved adhesive manufacturer's preparation instructions on the packaging and the
manufacturer's written paper instructions.
E
C. Application of Adhesive
1. Using a trowel, apply prepared adhesive only to area on the back side (that will be adhered to the
substrate) of the Tuscan Stone piece.
2. Apply the adhesive in a %4" thick layer to cover approximately the middle 2/3 of the back side.
3. Do not apply adhesive all the way to the edge of the back side.
4. Do not apply adhesive to the end (grouting) areas of the Tuscan Cast Stone piece.
D. Attaching Tuscan Cast Stone to Substrate
1. Take prepared Tuscan Cast Stone piece (with adhesive applied) to the substrate.
2. Press the Tuscan Cast Stone piece against the substrate, press firm to achieve full contact of adhesive
with substrate.
3. Align Tuscan Cast Stone pieces in the same plane as the visible outside surfaces of adjacent pieces.
4. Use positive means, such as spacers, to maintain consistent grouting joint width spacing.
E. Temporary Support for Tuscan Cast Stone pieces
1. Using positive means such as screws, nails, wires, straps, tapes, ties or props, support the Tuscan Cast
Stone piece so as to maintain adhesion and correct position while the adhesive is curing. Do not run
fasteners through the Tuscan Cast Stone pieces.
2. In some cases the foam core can be notched out on the backside of the Tuscan Cast part and placed
over an anchored support such as a 2x4 or 4x4 as a means to maintain adhesion and correct position
while the adhesive is curing. Larger parts may need wire or brick ties attached to top of the part to keep
it from pulling away from the wall.
F. Curing of Attachment Adhesive
1. Maintain temperature above 40 for at least 24 hours as the adhesive sets.
2. Protect the Tuscan Cast Stone pieces from physical damage and precipitation during curing period.
G. Grouting Between Tuscan Cast Stone pieces
1. Place strippable painters masking tape continuously on either side of joint at the edge of the Tuscan
Cast Stone piece.
2. Using specified Tuscan Grout color and caulking gun, apply the Tuscan Grout material Into the joint.
Use of backer rod may be required to avoid shrinking and unnecessary high - volume use of Tuscan
Grout. Total recommended thickness of Tuscan Grout is 1/8", do not exceedY4' .
3. Using standard caulking tools or thumb tip, force the Tuscan Grout into the joint and against the edge of
the Tuscan Cast Stone pieces, and make the grouting slightly convex and flush with the outside face of
the Tuscan Cast Stone piece (this process is called °tooling the joint).
4. Remove masking tape immediately after the Tuscan Grout has been tooled.
v � H. Applying Sealer (for all uses of Tuscan Cast Stone)
. 1. General
a. Avoid application in direct sunlight.
1. Apply Tuscan Exterior Flat Sealer after parts have had time to cure. Minimum 7 days.
0 2. Apply (2) two coats of Tuscan Exterior Flat Sealer in a continuous application.
3. Apply by brush, roller, sprayer, or sponge.
CJ I. Protection
1. Protect installed materials from water impinging on the visible surface, grout, sealants joints, and from
behind.
2. Protect installed materials from dust, dirt, precipitation, freezing, damaged, spilled materials, and
continuous high humidity until they are fully dry.
J. Cleanup and Job Close -Out
1. Remove temporary supports, if employed, once adhesive and Tuscan Grout has set.
COD 2. Remove left over materials from work area and dispose of properly.
3. Refurbish any adjacent areas adversely affected by this work.
