Construction of a new 24'×24' freestanding wood-framed patio cover (pergola) on the existing concrete patio at the south side of the Von Ebert Brewing taproom. Structure consists of 16 pressure-treated DF-L #2 posts in a 4×4 grid bearing on cast-in-place concrete pier footings, with 4×10 beams, 2×8 rafters at 24 in o.c., and corrugated translucent polycarbonate panels on a 1:12 slope. Project includes four overhead 6 kW electric infrared heaters served by a new dedicated 240 V circuit from the existing building subpanel, plus a gutter / downspout system at the low-side eave. No new impervious surface — entire footprint is existing concrete patio.

This sheet documents that the proposed pergola does not change the occupancy classification, occupant load, exit count, or travel distances of the existing facility.
| Existing occupancy classification | A-2 Assembly (restaurant / drinking establishment) |
|---|---|
| Existing occupant load | 50 (declared) |
| New seats added by this scope | 0 |
| Proposed occupant load | 50 (no change) |
| Occupancy threshold crossed? | No — already > 50 occupants under existing operation |
| Change-of-Occupancy permit? | Not required |
| Existing exit count | Per existing taproom plan (no change) |
|---|---|
| Maximum travel distance (A-2, sprinklered) | ≤ 250 ft per OSSC Table 1017.2 |
| Travel distance from farthest pergola seat to nearest exit | Within existing exit path; ≤ 100 ft estimated (verify on existing taproom plan) |
| Common path of egress travel | Unchanged from existing |
| New exits required by this scope | None |
The pergola is a roof + heater installation above an existing outdoor patio dining surface. It does not add seats, does not change the food/drink service area boundaries, does not modify any required exit path, and does not change the occupancy classification of the facility. The existing egress strategy of the commercial assembly occupancy remains in place unaltered. No exit signs, emergency lighting, or egress hardware modifications are required by this scope.
This sheet documents that the proposed pergola does not alter the existing accessible route, accessible seating count, or any other ADA / ICC A117.1 features of the facility.
| Public way access | From N Cook St + N Mississippi Ave (existing sidewalks) |
|---|---|
| Route to existing patio dining | Existing — no change by this scope |
| Route running slope | Existing concrete patio is level; verify ≤ 1:20 (5%) |
| Route cross slope | Verify ≤ 1:48 (2%) per ICC A117.1 §403 |
| Clear width | ≥ 36" maintained between pergola posts (8' bay spacing >> minimum) |
| Surface | Existing concrete: firm, stable, slip-resistant per ICC A117.1 §302 |
| Door/threshold transitions | None added; existing taproom doors unchanged |
| Total dining seats (existing) | per existing taproom seating plan |
|---|---|
| Required accessible seats | 5% of fixed dining seats, minimum 1 per OSSC 1108.2.9 |
| New seats added by pergola scope | 0 |
| Accessible seating provided | Existing — distributed within the dining area; no change required |
| Approach + maneuvering clearance | 30" × 48" min at each accessible space — verify against existing layout |
Project valuation is approximately $26,661. Per OSSC Ch. 11 priority order, 25% of accessibility-related project cost may be applied to barrier removal if existing facility is non-compliant. Existing facility is already operating as a licensed A-2 assembly and is presumed compliant with the prior occupancy of record; field-verify accessible route from public way before construction. If any segment is found non-compliant, allocate ~$6,650 budget priority to barrier removal (parking → entry → routes → other).
Typical structural connections (top row) and layered assembly cutaways (bottom row) — not to scale. Simpson Strong-Tie hardware specified throughout; approved equivalents acceptable subject to engineer-of-record review. Capacities to satisfy demands listed on S-301 Hardware Demands.

If you want to over-engineer this design (e.g. operator preference, anticipated future loads, gut-check belt-and-suspenders): each member bumped to the next standard nominal size, re-run through the same capacity checks. DCR is the governing demand/capacity ratio (lower = more headroom). Margin = 1 − DCR.

Each heater = 80 lb hung from underside of beam/rafter at a designated location. Use manufacturer-supplied mounting bracket lagged into solid blocking. Provide simple span point-load capacity in member design (covered below).
Each heater = 80 lb hung point load at a beam underside. With 2x8 rafters @ 24" o.c., confirm rafter at each location carries the point load on top of uniform demand, or mount the bracket to a beam. Solid blocking required between paired rafters at bracket locations.
