RE: CHANGE ORDER SCOPE-OF-WORK NARRATIVE (PERMIT #0253.2018.ARBK)
New-Build PRIVATE RESIDENCE • FOUNDATION REVISION
813 W. SMUGGLER STREET
ASPEN, CO 81611
TO WHOM IT MAY CONCERN:
The General Contractor, MM-Eight Construction, has asked us to value
engineering the foundation to reduce complexity, excavation & the amount of
concrete required. To that end, Albright Associates, our Structural consultant,
and Sin-BAD are herewith submitting this Change Order application regarding our
“RL3” project at 813 W. Smuggler.
In response to new input from Kumar & Associates, Albright has re-engineered the
foundation walls to reduce the footing size. Along considerable lengths of the
wall (primarily at the north & west), we are eliminating the large toes and heels,
leaving the walls with more typical spread footers, restrained by the floor
diaphragm, versus the unrestrained retainer wall design previously. In other
instances, where exterior grade is higher (primarily at the east), the retaining
wall design has been kept. A requirement to change our engineering parameters
is to raise the basement slab, and reduce foundation wall height, by 6 1/2” from
87’-5 1/2” to 88’-0”.
Albright is also revising the T/Wall elevations along the east side of the home to
correspond with the finish grade elevations shown in the Architectural set,
which were previously noted as "TW See Arch".
To illustrate these changes, Albright is submitting a revised Structural set, with
revisions clouded as Delta #1, and a supporting letter from Kumar & Associates.
On the Architectural side, we herewith submit:
1. A revised Sheet A3.1 Lower Level Plan showing a higher slab elevation &
one less tread/riser on the stairway;
2. Revised elevation drawings & building sections to show the 6 1/2” raised
basement slab; &
3. Revised sheets Z1 Zoning Summary & Z2 Sub-Grade Wall Area Calculations
to reflect a 6 1/2” higher basement slab, and corresponding higher grades
at window wells (with these changes, our exposed area ratio is reduced
from 14.2% to 13.9%, making the home approximately 122 SF under our
Allowable Floor Area, versus 114 SF before).
