DWG./SPEC. REFERENCE:

QUESTION:The plumbing fixture schedule specifically calls for three (3) types of lavatories. (LAV1 – HC, LAV2 – HC & LAV3 – HC) If you review the plumbing drawings all lavs are marked as LAV – HC and they do not coincide with the plumbing fixture schedule. The single lavatory sinks appear to be LAV1 – HC (and the make & model would be fine, however as per the plumbing schedule LAV2 – HC & LAV3 – HC call for the same make & model. These would appear to be Bradley MG3 series – a three (3) sink molded assembly. However the drawings show only two (2) banks of three (3) sinks and four (4) banks of four (4) sinks. Please advise upon how to proceed?

ANSWER:On Plumbing Fixture schedule, revise as follows:

LAV1-HC revise to LAV-HCLAV2-HC – deleteLAV3-HC – delete

DWG./SPEC. REFERENCE:

QUESTION:

Please clarify intent for the tops of the full-height wardrobe cabinets. Detail A-

551/7 shows what looks like a shop-made plastic laminate countertop on top of the

wardrobe instead of a standard finished cabinet top. There is also a note for PLAM

on moisture-resistant core (which is what we’d use for a shop-made laminate

countertop that had a sink in it). This is very unusual & also unnecessary for the

top of a 7-foot-tall cabinet. Is this correct or is it an error? Note that specs in 06 40

00 do not include plastic laminate countertops.

ANSWER:

Provide plastic laminate on standard substrate as indicated in specification section

06 40 23.

is correct? Note that melamine would be more cost effective than high pressure

laminate and would meet AWS standards for casework.

D. Install sheet metal flashing and trim true to line and levels indicated. Provide uniform, neat seams with minimum exposure of solder, welds, and elastomeric butyl sealant.

E. Install sheet metal flashing and trim to fit substrates and to result in watertight performance. Verify shapes and dimensions of surfaces to be covered before fabricating sheet metal. 1. Space cleats not more than 12 inches (305 mm) apart. Anchor each cleat with

two fasteners. Bend tabs over fasteners.

F. Expansion Provisions: Provide for thermal expansion of exposed flashing and trim. Space movement joints at a maximum of 10 feet (3 m) with no joints allowed within 24 inches (610 mm) of corner or intersection. Where lapped or bayonet-type expansion provisions cannot be used or would not be sufficiently watertight, form expansion joints of intermeshing hooked flanges, not less than 1 inch (25.4 mm) deep, filled with elastomeric butyl sealant concealed within joints.

G. Fasteners: Use fasteners of sizes that will penetrate substrate not less than 1-1/4 inches (32 mm) for nails and not less than 3/4 inch (19 mm) for wood screws. 1. Galvanized or Prepainted, Metallic-Coated Steel: Use stainless-steel fasteners. 2. Aluminum: Use aluminum or stainless-steel fasteners. 3. Copper: Use copper, hardware bronze, or stainless-steel fasteners. 4. Stainless Steel: Use stainless-steel fasteners.

H. Seal joints with elastomeric butyl sealant as required for watertight construction. 1. Where sealant-filled joints are used, embed hooked flanges of joint members not

less than 1 inch (25.4 mm) into sealant. Form joints to completely conceal sealant. When ambient temperature at time of installation is moderate, between 40 and 70 deg F (4 and 21 deg C), set joint members for 50 percent movement either way. Adjust setting proportionately for installation at higher ambient

Do not solder prepainted, metallic-coated steel and aluminum sheet. 2. Pretinning is not required for lead. 3. Stainless-Steel Soldering: Pretin edges of uncoated sheets to be soldered using

solder recommended for stainless steel and phosphoric acid flux. Promptly wash off acid flux residue from metal after soldering.

4. Do not use open-flame torches for soldering. Heat surfaces to receive solder and flow solder into joints. Fill joints completely. Completely remove flux and spatter from exposed surfaces.

J. Aluminum Flashing: Rivet or weld joints in uncoated aluminum where necessary for strength.

3.03 ROOF DRAINAGE SYSTEM INSTALLATION

A. General: Install sheet metal roof drainage items to produce complete roof drainage system according to SMACNA recommendations and as indicated. Coordinate installation of roof perimeter flashing with installation of roof drainage system.

B. Hanging Gutters: Join sections with riveted and soldered joints or with lapped joints sealed with elastomeric butyl sealant. Provide for thermal expansion. Attach gutters at eave or fascia to firmly anchored gutter brackets and straps spaced not more than 36 inches (914 mm) apart. Provide end closures and seal watertight with sealant. Slope to downspouts. 1. Fasten gutter spacers to front and back of gutter. 2. Loosely lock straps to front gutter bead and anchor to roof deck. 3. Anchor back of gutter that extends onto roof deck with cleats spaced not more

than 24 inches (610 mm) apart. 4. Install gutter with expansion joints at locations indicated but not exceeding 50

feet (15.25 m) apart. Install expansion joint caps.

C. Downspouts: Join sections with 1-1/2-inch (38-mm) telescoping joints. Provide fasteners designed to hold downspouts securely 1 inch (25.4 mm) away from walls; locate fasteners at top and bottom and at approximately 60 inches (1524 mm) o.c. in between. 1. Provide elbows at base of downspout to direct water away from building. 2. Connect downspouts to underground drainage system indicated.

3.04 ROOF FLASHING INSTALLATION

A. General: Install sheet metal roof flashing and trim to comply with performance requirements, sheet metal manufacturer's written installation instructions, and SMACNA's "Architectural Sheet Metal Manual". Provide concealed fasteners where possible, set units true to line, and level as indicated. Install work with laps, joints, and seams that will be permanently watertight.
