I am also including our signed encroachment application with requested exhibits. During my presentation to the planning and zoning commission, there were three requests made for additional information to present for City Council review: 1. Show the proposed location of valet parking spots and attendant station. Although this item is under separate permit, I have included the proposed location for valet parking that the owner has requested on the attached site plan (Exhibit A). 2. Show acoustical materials to be used on the soffit of the proposed canopy to help with noise attenuation. We will install an acoustical metal soffit and acoustical plaster finish on the underside of the patio. I am including cut sheets on there products for reference (Exhibit B). 3. Show a design option for the patio columns with masonry bases. Although the design as proposed is in compliance with the adopted Downtown District design guidelines, we are providing the attached rendering and plan of the patio with masonry pediments at the request of the planning commissioner (Exhibit C). Since the 1217 Main Street / Suite 500 / Dallas, Texas 75202 (w) 214 670 0050 (f) 214 670 0052 www.5Gstudio.com 5Gstudio _collaborative patio is not a large space, these pediments would limit the ability of the owner to property furnish and seat the patio. Also, we don’t feel these elements add to the character of the façade or help visually connect the façade with adjacent storefronts. 184 TechLine 877 276 7876 armstrongceilings.com/metalworks MetalWorks™ Linear Ceiling System in Effects™ Wood Looks Walnut Espresso KEY SELECTION ATTRIBUTES • New universal suspensions system will enable easy installation and a clean finished visual • Nominal 2", 4", 6", 8", 10", and 12" wide panels, including nominal 1" reveal • Discontinuous ceilings possible with Effects™ trim or Axiom® trim, using the new Adjustable Trim Clip • Mix and match widths for a striated visual • Install in the ceiling, on the wall • Create 90º angled or curved ceiling-to-wall transitions • Available for exterior applications, tested to meet wind uplift Classes 30, 60, and 90 • Acoustical options with microperforated panels • Fast and easy installation METALWORKS™ Linear METALWORKS Linear Exterior smooth texture Durable, metal panels in more widths for a variety of flexible and unique acoustical interior/exterior solutions.

For quiet elegance, turn to the sound-rated ceiling spray texture that dries to an elegant, natural white ﬁnish. USG Acoustical Plaster Finish is an exclusive, sound-rated interior spray-applied texture ﬁnish for ceilings and other noncontact surfaces over basecoat plaster, concrete, metal decks and gypsum panels. –D esigned for new construction, repair and remodeling –R ated for sound absorption and surface burning characteristics – Easy spray application – Dries to an attractive natural white ﬁnish Description USG Acoustical Plaster Finish is designated Class A for surface ﬂame spread per ASTM E1042-85. It offers the advantages of a dramatic texture ﬁnish with acoustical absorption. USG Acoustical Plaster Finish is ideal for new construction, as well as for repair and remodeling projects. It is easy to use, and mixes with water at the jobsite. USG Acoustical Plaster Finish is a setting-type plaster product that is designed to be applied by standard plaster spray application techniques. For successful, trouble-free application, all product directions must be followed, and the recommended equipment must be used. Advantages Powder product mixes quickly with water to the proper consistency. Provides a monolithic, sound-absorbing surface. Dries to a high-style, problem-free surface, saving both time and money. Limitations 1. For interior use over basecoat plaster, metal deck, concrete and gypsum panel ceilings, and on other noncontact surfaces. Do not use USG Acoustical Plaster Finish on surfaces previously painted with epoxy-type paints. If sur- face was previously painted with a “hard shell” ﬁnish such as on oil-based paint or semi-gloss or gloss latex paint, sand surface with 80-100-grit sandpaper, or sandblast the surface. Apply a prime coat of SHEETROCK® Brand First Coat and let dry. For concrete surfaces previously coated with a decorative texture ﬁnish, the texture ﬁnish should be removed and the surface cleaned and primed (per application directions) before applying USG Acoustical Plaster Finish. Previously painted metal decking must be stripped to bare metal prior to application of USG Plaster Bonder-Clear to ensure adequate bond. USG Acoustical Plaster Finish is not recommended for use with gypsum panels previously coated with a decorative texture ﬁnish because of increased sag potential. 2. Surface irregularities will “mirror” or “photograph” through the ﬁnish. Level offsets and irregularities prior to ﬁn- ish application with either SHEETROCK® Setting-Type (DURABOND®) or Lightweight Setting-Type (EASY SAND®) Joint Compound, or with USG Acoustical Plaster Finish. 3. Sound ratings can vary depending upon thickness and uniformity of coating, amount of dilution, mixing time, spray pressure and technique. 4. Application is limited to noncontact surfaces. 5. Finish is a setting-type product. At the end of the workday, all equipment must be purged with water until the system is clean. 6. Do not add paint or tinting pigments to product mix, because they will adversely affect the viscosity and spray application properties. 7. Minimum thickness application is 1/4 . Less than 1/4 application will not set properly, and will cause color vari- ation. Maximum thickness of application is 1/2 over drywall. More than 1/2 will cause gypsum board sag. For maximum sound rating, ﬁnish may be applied to a 1 thickness over basecoat plaster, metal decks and concrete surfaces. The 1 thickness must be applied in two 1/2 coats to ensure proper thickness, appearance and increased sound rating. 8. USG Acoustical Plaster Finish can result in sagging of gypsum drywall and veneer plaster ceilings under these conditions: high heat and humidity, improper ventilation and/or board application to framing, and insufﬁcient board thickness for span between supports. Avoid high heat/humidity conditions, and provide adequate ventila- tion after spraying is completed, and until USG Acoustical Plaster Finish has set and dried completely. When using USG Acoustical Plaster Finish, refer to the following table: Board Application Method Maximum Frame Thickness (Long edge relative to frame) Spacing o.c. inch mm inches mm 3/8 9.5 Not recommended — — 1/2 12.7 Perpendicular only 16 406 5/8 15.9 Perpendicular only 24 610 Note: Double layer laminated, 3/4 or greater total thickness—24 o.c. Data Sheet USG® A coustical Plaster Finish 9. Be sure substrate surface is clean, dry, sound, and free of oil, grease, efﬂorescence, contaminants and water soluble materials. Prime surface per surface preparation directions. On retroﬁt jobs, some substrates may con- tain or be coated with contaminants or migrating materials that will not respond to standard surface preparation methods, and surface staining of the ﬁnish may occur. In such situations, a light spray coat of SHEETROCK Brand First Coat over the dried USG Acoustical Plaster Finish will be required to improve the surface color. (There will be minimal loss in NRC value. Test a small area to determine effectiveness of spray coat of paint.) Accordingly, in retroﬁt jobs, a ﬁnish coat of paint should be included in the bid. If an encapsulant has been used, USG Acoustical Plaster Finish is recommended only over the following tested and approved coatings: Cable Coating 22P by American Coatings Corporation; CerTane 900, 1,000, and 2,000 by Certiﬁed Technologies Corporation; Chil-Lock CP 240 and CP-215 by Childers Products Company, Inc.; Encotec 10X-A Tie Coating by Encotec Insu- lation Company, Inc.; 32-60 and 32-22 by Foster Products Corporation; Control Series 2,000 by Grayling Indus- tries; SK-13-1C by International Cellulose Corporation; Seriﬂex; HD-200 by Valcraft; Fiberset FT, PM, and A-B-C by Fiberlock Technologies, Inc.; Hi-Bond by Highland Products; Guardian Bridging Encapsulant by Control Resource Systems, Inc.; Asbestite Color (White) and Asbestite Bond (Clear) by Arpin Products, Inc.; SEAL-KRETE Waterprooﬁng Sealer by Seal-Krete Inc. Directions Surface Preparation Gypsum plaster basecoats either conventional or veneer type—must be prepared in accordance with the appli- cation for the speciﬁc product, and the surface left uniform without voids but rough and open to ensure proper suction and bond of the ﬁnish plaster application. Best results are achieved when USG Acoustical Plaster Finish is applied to a basecoat which is properly set and practically dry. It is recommended that dry basecoats be dampened slightly to reduce exceessive suction and enhance bonding. Concrete surfaces Surfaces must be dry, clean, sound, and free of oil, grease, efﬂorescence, contaminants and water-soluble materials. Prime exposed metal with a good, ﬂat, rust-inhibitive primer. Age new concrete 60 days or more before covering. After the forms are removed from new monolithic concrete surfaces, grind down all ﬁns and other projections and remove grinding dust and sludge. Complete necessary patch work on surfaces prior to texturing. Use SHEETROCK Brand Setting-Type Joint Compound (DURABOND) or SHEETROCK Brand Lightweight Setting-Type Joint Compound (EASY SAND). If the entire surface requires leveling, apply a coat of USG™ Plaster Bonder, let dry, then apply either a conventional plaster basecoat of sanded RED TOP® Gypsum Plaster or a veneer plaster basecoat using IMPERIAL® Brand Basecoat or DIAMOND® Brand Veneer Basecoat. Leave basecoat surface level but rough and open to promote bond of the ﬁnish coat. Concrete slab offsets may also be ﬁlled with USG Acoustical Plaster Finish, then troweled smooth and followed with a ﬁnal spray application of USG Acoustical Plaster Finish. Metal decks Previously painted metal decking must be stripped to bare metal. Prior to application of USG Acoustical Plaster Finish apply a coat of USG Plaster Bonder to ensure adequate bond. Apply undiluted bonding agent to uniformly cover metal roof decking. Coverage of the bonding agent will be approximately 300 sq. ft./gal. Bonding agent may be spray applied with an airless sprayer using a 60-mesh ﬁlter and a 0.017 tip, or can be roller applied. Bonding agent must be allowed to dry before application of ﬁnish. Gypsum panels Surfaces must be dry, clean, sound, and free of oil, grease, efﬂorescence, contaminants and water-soluble materials. Finish gypsum panel surface with a conventional joint treatment system (see procedures in USG Gyp- sum Construction Handbook, H17), using SHEETROCK Brand Joint Treatment products. When prepared surfaces are dry, apply a prime coat of SHEETROCK Brand First Coat. Paint should be applied undiluted and allowed to dry before applying USG Acoustical Plaster Finish. Previously painted surface Apply prime coat of SHEETROCK Brand First Coat and let dry. If surface was previously painted with a “hard shell” ﬁnish such as an oil-based paint or a semi-gloss or gloss latex paint, sand surface with 80-100-grit sandpaper or sandblast the ﬁnish, and then apply prime coat. Previously textured surface Remove decorative texture ﬁnish and clean substrate. Prime surface by applying a coat of SHEETROCK Brand First Coat and let dry. Encapsulants Not all encapsulant materials are alike. USG Acoustical Plaster Finish is recommended for application over spe- ciﬁc substrate encapsulants. See item No. 9 in Limitations section for approved encapsulants. Spray Equipment Rotor/stator (Moyno pump), peristaltic pump and piston pump may be used. Use minimum length material hose with minimal number of couplings to reduce clogging. Mixed product will remain sprayable for 3 to 4 hours before set. Pump and hose must be cleaned with water followed by approximately one gallon of SHEETROCK Brand Ready-Mixed Joint Compound prior to spray application, or severe aggregate separation and plugged hoses will result. Clean equipment thoroughly between and after applications. Use plaster system scouring sponges to prevent buildup inside hoses. Rotor/stator (Moyno pump)—Use Robbins-Myers 2L4 pump or similar equipment as minimum pump size with pole gun with 1/4 -1/2 round oriﬁce. Use 3/4 -1 i.d. material hose. Peristaltic pump—Use pump with minimum 1 i.d. internal pumping and material hose. Use pole gun with 1/4 - 1/2 round oriﬁce. Use minimum 1 i.d. material hose. Piston pump—Use a Grover 8:1 or higher ratio, double-action pump or similar equipment with either a pole gun with 1/4 -1/2 round oriﬁce, or a Binks 7E-2 handgun with a 1/4 -1/2 round opening. Use minimum 3/4 i.d. material hoses. Graco pumps are not recommended. Mixing Recommended equipment Use a 7 cu. ft. or larger paddle-type plaster mixer with rubber-tipped blades (e.g., Anchor mixer) with horizontal shaft or texture rig-type mixer with paddles mounted on a horizontal shaft. Mixing method To ensure uniform product performance, a minimum mix quantity of two 30 lb. bags of USG Acoustical Plaster Finish is recommended. Use 3.5 gal. water per 30 lb.of ﬁnish. Add powder to water. Blend thoroughly (approxi- mately 5 minutes) with mechanical mixer, until material is lump-free and has a thick, foamy consistency. Initial mix will appear dry and heavy; continue to mix until material is thick and foamy. If material is overmixed, exces- sive foam will appear. Add powder to break down foam and remix until proper foam level is achieved. Additional mixing may be necessary during application to maintain foam consistency. Use wet-mixed material within 3-4 hours. Store bags in a dry place and protect from moisture. Application Spray Application Procedure for all pumping systems: Initially ﬁll mixing hopper with necessary water to ﬂush hoses. Pump all water from hopper, then place joint compound into material reservoir of pump. Pump until all the joint compound feeds into the hose, then stop the pump. Note: All pumps and hoses must be cleaned initially with water, followed by approximately 1 gal. of SHEETROCK Brand Ready-Mixed Joint Compound prior to spray application, or severe aggregate separation and plugged hoses will result. Add mixed ﬁnish to material hopper, pump out and discard clean-out water, joint compound and intermixed ﬁn- ish until clear material is obtained. Turn on atomizing air and adjust to obtain a 1-1/2 -3 diameter pattern. The spray gun typically should be held 2 -4 (depending upon material and atomization pressures) from the sur- face to be sprayed. Finish material may be applied to up to a 1/2 thickness in a single coat. Best results are achieved by the fol- lowing recommended procedure. Apply USG Acoustical Plaster Finish evenly, holding pole gun perpendicular to surface being sprayed and slowly waving spray gun from side to side until area is covered. Immediately double- back, crosshatching (diagonal pattern to the initial application) the prior coat. Repeat same procedure as neces- sary until desired thickness is reached. A 1 thickness must be applied in two separate 1/2 applications to ensure increased sound rating. Elimination of spray lines and section seams (overlaps) is essential in producing an acceptable ﬁnish. If the entire ceiling area cannot be sprayed to the ﬁnal thickness in one day, spray the entire surface with a material coat of a uniform, even thickness (minimum 1/4 ). Complete the buildup to the ﬁnal thickness the following day with a crosshatched application to provide a uniform appearance. Do not spray a portion of a ceiling one day and the ﬁnal portion on another day, as a noticeable seam line will result. Use nat- ural breaks and boundaries to “frame” pattern edges and conceal seams. For average thickness measurement, take a blunt-tipped object (head of pencil or ﬁnishing nail) and mark the object with the thickness to be sprayed. Insert measuring device into ﬁnish and determine whether depth sprayed is correct. For a different surface color, a good quality, ﬂat latex paint (white or pastel) may be spray-applied over the dried, ﬁnished USG Acoustical Plaster Finish. There will be minimal loss in NRC value. Cautions 1. Surface irregularities will “mirror” or “photograph” through the ﬁnish. Level offsets/irregularities in substrate sur- face prior to ﬁnish application. 2. The purpose of applying a prime coat is to equalize surface porosity and reduce transparency. Prime coats are not intended to reduce sag potential or to prevent migrating stains or contaminants from leaching to the ﬁnished surface. 3. All pumps and hoses must be initially ﬂushed with water, followed by approximately 1 gal. SHEETROCK Brand All- Purpose Ready-Mixed Joint Compound to prevent aggregate separation and clogging. 4. USG Acoustical Plaster Finish is a setting-type product. Use wet-mixed material within 3-4 hours. At the end of the workday, purge all equipment with water until system is clear. Hose connections must not signiﬁcantly reduce interior diameter of hoses. Improper connections can result in blocking. 5. If blockage occurs in hose, turn off air pressure and pump. If equipment has a reverse gear, pump slurry into mixing hopper. If blockage occurs at nozzle, disconnect nozzle from gun and direct material into large container to remove obstruction. 6. For temporary shut-downs (30 min.), it is not necessary to remove material from hose. For longer breaks, purge material to prevent hard pumping or setting of material in equipment. Finish will pack and separate in spray gun upon shut-down unless pump pressure is relieved. Always shut down spraying process in sequence: 1) Turn off pump, 2) Spray product until back pressure is relieved, 3) Turn off material valve, 4) Turn off atomizing air. Reverse the sequence for startup. 7. Maintain minimum air, water, product mix and substrate temperature of 55 °F (13 °C) during and after applica- tion, taking care to ensure adequate ventilation until building is occupied. Do not use unvented gas or oil heaters. 8. Wipe overspray off promptly, because ﬁnish resists clean removal after extended contact with substrate. After wipedown, any remaining dried residue can be removed by light sanding. 9. Minimum thickness application is 1/4 . Less than 1/4 application may not set completely, causing dry-out and color variation. 10. Maximum thickness of application is 1/2 over gypsum panel systems. More than 1/2 will cause gypsum board sag. For maximum sound rating, ﬁnish may be applied to a 1 thickness over concrete and basecoat plaster. The 1 thickness must be applied in two separate 1/2 applications to ensure increased sound rating. 11. Do not reuse or intermix ﬁnish from overspray with freshly mixed ﬁnish. Intermixing overspray will accelerate the setting time of ﬁnish, causing short working time, and will also result in reduced bond and hardness of ﬁnish. 12. Do not add paint or tinting pigments to USG Acoustical Plaster Finish, as they will adversely affect viscosity and spray application properties. 13. Sound ratings can vary depending on thickness and uniformity of coating, amount of dilution, mixing time, spray pressure and techniques used. 14. Actual coverage range may vary depending on such factors as amount of product dilution, spray techniques, uniformity of coating and condition of substrate surface (e.g., coverage may be less on rough, uneven and/or high-suction surfaces).

It is recommended that dry basecoats be dampened slightly to reduce exceessive suction and enhance bonding. Concrete surfaces: Surfaces must be dry, clean, sound, and free of oil, grease, efﬂorescence, contaminants and water-soluble materials. Prime exposed metal with a good, ﬂat, rust-inhibitive primer. Age new concrete 60 days or more before covering. After the forms are removed from new monolithic concrete surfaces, grind down all ﬁns and other projections and remove grinding dust and sludge. Complete necessary patch work on surfaces prior to texturing. Use SHEETROCK Brand Setting-Type Joint Com- pound (DURABOND) or SHEETROCK Brand Lightweight Setting-Type Joint Compound (EASY SAND). If the entire sur- face requires leveling, apply a coat of USG Plaster Bonder, let dry, then apply either a conventional plaster basecoat of sanded RED TOP Gypsum Plaster or a veneer plaster basecoat using IMPERIAL Brand Basecoat or DIAMOND Brand Veneer Basecoat. Leave basecoat surface level but rough and open to promote bond of the ﬁn- ish coat. Concrete slab offsets may also be ﬁlled with USG Acoustical Plaster Finish, then troweled smooth and followed with a ﬁnal spray application of USG Acoustical Plaster Finish. Metal decks: Previously painted metal decking must be stripped to bare metal. Prior to application of USG Acoustical Plaster Finish apply a coat of USG Plaster Bonder to ensure adequate bond. Apply undiluted bonding agent to uniformly cover metal roof decking. Coverage of the bonding agent will be approximately 300 sq. ft./ gal. Bonding agent may be spray applied with an airless sprayer using a 60-mesh ﬁlter and a 0.017 tip, or can be roller applied. Bonding agent must be allowed to dry before application of ﬁnish. Gypsum panels: Surfaces must be dry, clean, sound, and free of oil, grease, efﬂorescence, contaminants and water-soluble materials. Finish gypsum panel surface with a conventional joint treatment system (see proce- dures in USG Gypsum Construction Handbook), using SHEETROCK Brand Joint Treatment products. When pre- pared surfaces are dry, apply a prime coat of SHEETROCK Brand First Coat. Paint should be applied undiluted and allowed to dry before applying USG Acoustical Plaster Finish. Previously painted surface: Apply prime coat of SHEETROCK Brand First Coat and let dry. If surface was previously painted with a “hard shell” ﬁnish such as an oil-based paint or a semi-gloss or gloss latex paint, sand surface with 80-100-grit sandpaper or sandblast the ﬁnish, and then apply prime coat. Previously textured surface: Remove decorative texture ﬁnish and clean substrate. Prime surface by applying a coat of SHEETROCK Brand First Coat and let dry. Encapsulants: Not all encapsulant materials are alike. USG Acoustical Plaster Finish is recommended for applica- tion over speciﬁc substrate encapsulants. See Limitations for approved encapsulants. Note: The purpose of applying a prime coat is to equalize surface porosity and reduce transparency when USG Acoustical Plaster Finish is applied as a ﬁnished thickness of 1/4 over gypsum panel applications or previously textured painted surfaces. Primers are not intended to reduce sag potential or to prevent migratory stains or contaminants from leaching to the ﬁnished surface. On retroﬁt jobs, some substrates may contain or be coated with contaminants or migrating materials that will not respond to standard surface preparation methods, and surface staining of the ﬁnish may occur. In such situations, a light spray coat of SHEETROCK Brand First Coat over the dried USG Acoustical Plaster Finish will be required to improve the surface color. (There will be minimal loss in NRC value. Test a small area to determine effectiveness of spray coat of paint.) Accordingly, in retroﬁt jobs, a ﬁnish coat of paint should be included in the bid. 3.2 Apply ﬁnish according to product directions. Finish must be evenly spread and free from runs, sags and other Application blemishes. Use only mixing equipment and pump sizes (piston pump, rotor/stator and peristaltic pump) as spec- iﬁed in the directions. Product Data Color: White. Filler: Calcium sulfate. Dilution (Water): 3.5 gal./30 lb. Coverage: Dried Thickness sq. ft./lb. 1/4 Approx. 3 1/2 Approx. 1-1/2 1 Approx. 1/2 Coverage range shown here should be considered an estimate. Actual coverage can vary based on factors such as amount of dilution of product, spray techniques and procedures, uniformity of coating and condition of sub- strate surface (e.g., coverage may be less on rough, uneven and/or high-suction surfaces). Drying Time: At 1/2 thickness under 75%/50% R.H. condition, surface should dry in approx. 1-2 days; total dry- ing should occur in 3-5 days, depending upon ventilation. Application must be dry before painting. Weight of dried application: 1.2 to 1.5 lb./sq. ft. at 1/2 thickness.
