1Under 18VAC50-22-30, the official abbreviation for Virginia glass and glazing contracting is:
A.GLZ
B.GLS
C.GGC
D.FEN
Explanation: 18VAC50-22-30 defines "Glass and glazing contracting" with the abbreviation GLZ. Virginia Board for Contractors specialty abbreviations are assigned in that section and appear on the license. GLS, GGC, and FEN are not the Board's GLZ designation.
2Per 18VAC50-22-30, which activity is inside the GLZ specialty?
A.Installation, assembly, repair, improvement, or removal of glass, mirrored glass, and glass substitutes for glazing
B.Installation of a new building electrical service for storefront lighting
C.Rough-in of sanitary waste piping at a storefront sill
D.Framing a new dwelling's structural roof trusses
Explanation: The GLZ definition covers installation, assembly, repair, improvement, or removal of all makes and kinds of glass, glass work, mirrored glass, and glass substitutes for glazing. It also covers fabricating and glazing frames, panels, sashes, and doors, or installing those items in any structure. Electrical service, plumbing rough-in, and structural roof framing are other classifications.
318VAC50-22-30 states that GLZ work may be installed in:
A.Any structure
B.Dwellings and townhouses only
C.Commercial buildings only
D.Interior tenant spaces only
Explanation: The GLZ definition says the specialty executes fabrication and glazing of frames, panels, sashes, and doors, or installs those items in any structure. It is not limited to dwellings, commercial shells, or interiors. Class and other specialties may further limit a firm's total license, but the GLZ function itself is not building-type limited.
4Which related materials does 18VAC50-22-30 expressly include in the GLZ specialty?
A.Standard methods of weatherproofing, caulking, glazing, sealants, and adhesives
B.Fire-sprinkler piping and heads
C.Primary electrical distribution ahead of the meter
D.On-site sewage drainfields
Explanation: After defining the glass and frame work, 18VAC50-22-30 states that the specialty includes installation of standard methods of weatherproofing, caulking, glazing, sealants, and adhesives. Those items belong with the glass installation. Sprinklers, utility electrical distribution, and drainfields are other specialties.
5Besides a GLZ specialty contractor, 18VAC50-22-30 says which licensees also provide the glass-and-glazing function?
A.CBC and RBC classifications and the HIC and CIC specialties
B.ELE and PLB classifications only
C.H/H and SPR classifications only
D.No other classification or specialty may perform GLZ work
Explanation: The last sentence of the GLZ definition states that the CBC and RBC classifications and the HIC and CIC specialties also provide for this function. Electrical, plumbing, highway/heavy, and fire-sprinkler licenses are not listed as providing GLZ work. A firm still must stay inside the rest of its class and specialty limits.
6A Richmond storefront bid includes removing failed insulating glass, fabricating new aluminum doors, and recaulking the perimeter. Is that package inside GLZ?
A.Yes. Removal, fabrication of glazed doors, and standard recaulking are all named in the GLZ definition
B.No. Removal of existing glass is demolition and requires a separate demolition specialty
C.No. Fabricating doors is finish carpentry (FIN) only
D.No. Perimeter caulk is painting and wallcovering (PTC) only
Explanation: GLZ expressly includes removal of glass, fabrication and glazing of frames, panels, sashes, and doors, and standard weatherproofing, caulking, glazing, sealants, and adhesives. The bid items are the core GLZ function. Other specialties may overlap some finishes, but they are not required for this glass package.
7Which product is a "glass substitute for glazing" that 18VAC50-22-30 places in the GLZ specialty?
A.Polycarbonate or acrylic sheet glazed into a framed opening
B.Structural steel wide-flange columns
C.Type L copper water tube
D.Asphalt shingle roofing
Explanation: The GLZ definition covers glass substitutes used for glazing. Transparent plastics such as polycarbonate and acrylic are the usual substitutes glazed into frames, sashes, and doors. Steel columns, copper water tube, and roof shingles are not glazing substitutes.
8A GLZ contractor is asked to install a complete aluminum storefront, glaze the lites, hang the entrance doors, and land the 120-volt feed for the automatic door operator. What is outside GLZ?
A.Landing the 120-volt power feed for the operator
B.Setting the aluminum storefront framing
C.Glazing the insulating lites
D.Hanging the glazed entrance doors
Explanation: Frames, glass, and glazed doors are inside the GLZ definition. Connecting building power to an automatic operator is electrical work under the USBC electrical provisions and the ELE classification. The glazier installs the door and operator hardware; a licensed electrician makes the circuit.
9Mirrored glass in a hotel corridor is bid as adhesive-set plates with J-mold and edge sealant. Under 18VAC50-22-30, this work is:
A.Inside GLZ, which names mirrored glass and the adhesives used to install it
B.Inside tile, marble, ceramic, and terrazzo (TMC) only
C.Inside painting and wallcovering (PTC) only
D.Unlicensed decorative work that needs no contractor specialty
Explanation: GLZ expressly includes mirrored glass and the adhesives, sealants, and standard installation methods used with it. TMC is tile and stone, and PTC is paint and wallcovering. Permanently annexed mirror work on a commercial corridor is contracting, not unlicensed decoration.
10A Class C firm holds only the GLZ specialty. The owner also wants the firm to build a new three-story wood-framed office shell and then glaze it. Which statement is correct?
A.GLZ covers the glass, frames, sashes, doors, and associated sealants, but not construction of the new commercial building shell
B.GLZ automatically includes the entire commercial building classification (CBC)
C.GLZ includes new dwellings but not commercial shells, so the office is allowed if called a townhouse
D.Any specialty contractor may construct a new building if glass will be installed later
Explanation: GLZ is a specialty service for glass, glass substitutes, mirrored glass, glazed frames/sashes/doors, and related weatherproofing. It does not confer CBC or RBC building classification rights. A new commercial shell needs the proper building classification. Relabeling the office a townhouse does not change the USBC occupancy or the license scope.
