Specification Sheet (PDF) | Photo GallerySHELTER SIZE
The size of the Dobson dugout cover is expressed by the depth and the length of the roof area. For example, the roof of a 8’ x 20’ Dobson shelter is 8’ deep and 20’ long, excluding the thickness of the 2” nominal size fascia boards. Custom sizes are also available.
THE DOBSON PACKAGE COMPONENTS
COLUMNS
Pressure treated, prior to gluing, laminated wood columns 10’ 9” long – to be embedded 2’ 9” in the concrete for stability. The lumber is treated prior to gluing which affords full penetration of the core of the columns. Special 4” annular nails to be “partially nailed” into the portion of the columns embedded in the concrete footings to provide improved anchorage against wind uplift.
BEAMS
Laminated wood beams that connect to the columns. Steel connections and bolts that connect the beams to the columns.
ROOF DECK
2x6 or 2x8 (nominal sizes) #1 grade, Southern Yellow Pine wood decking, tongue and groove, furnished in random or specified lengths at EnWood’s option. The decking is nailed to the top of the beams. Galvanized nails to attach the deck to the beams.
FASCIA
Pressure treated, 2x6, #1 grade Southern Yellow Pine, fascia board to be attached at the eaves. Galvanized nails to attach the fascia to the beam ends and the deck.
FELT & SHINGLES

DESIGN LOADS
- 12 pounds per square foot dead load
- 30 pounds per square foot live load
- 20 pounds per square foot wind load. (Equates to 100 MPH)
The typical design load allows for:
There are variables that affect the design sizes of the members, specifically the columns and the rafter beams, and those variables generally include live load conditions that are usually location specific. Building Codes normally dictate the applicable loads to be applied in the member size designs.
PRESSURE PRESERVATIVE TREATMENT
As noted in the component list above, the wood columns are fabricated with lumber pressure treated (prior to gluing) with CCA, at .6 pcf (6 tenths of a pound of preservative per cubic foot of wood) retention for “ground contact”. Fascia boards are treated with MCA or CCA,all the treatment per AITC 109. The treated glulam can be stained and painted.
