Read the spec first
Read 08 41 13 Aluminum-Framed Entrances and Storefronts and 08 80 00 Glazing. Curtain wall is in 08 44 13. Note the framing system, the finish and the performance rules. In the glazing section, read each glass type. A glass type is a full makeup: thickness, coating, air space and tint.
Sheets and schedules that carry the count
- The storefront and window type elevations. They show each frame with its sizes and glass types.
- The exterior elevations. They show where each frame type goes.
- The floor plans. They carry the frame tags and show interior glazing.
- The door schedule. It lists the aluminum entrance doors.
- The head, jamb and sill details.
- The glass type legend.
Steps in order
- List each frame type from the type elevations.
- Count how many of each type appear on the plans and elevations.
- Measure each frame for its vertical and horizontal members.
- List each glass lite with its size and glass type.
- Mark the lites that need safety glass.
- Count the entrance doors and their hardware.
- Measure perimeter sealant, sill flashing and any sunshades by length.
- Add interior glazing, mirrors and fire-rated glazing if they are in your sections.
Count, length, area or volume
- Count: frames by type, lites, doors, hardware sets and anchors.
- Length: framing members, sealant, sill flashing and trim.
- Area: glass by type, spandrel panels and mirrors.
- Volume: none.
Conflicts to find, and what to exclude
- The glass legend on the drawings differs from the glass types in the spec.
- The type elevation sizes do not match the wall openings on the plans.
- Entrance door hardware appears in the storefront section and in 08 71 00.
- A lite sits next to a door or near the floor with no safety glass mark.
- The spec requires engineering or testing that the drawings do not mention.
State who supplies steel supports, wood blocking and automatic door operators. Qualify engineered shop drawings and field water testing. Exclude final cleaning and glass protection unless your section includes them. State if glass in wood and hollow metal doors is yours.
