_____________________________________________________________________________________________
_____________________________________________________________________________________________
SHOP DRAWINGS:
The Structural Drawings are copyrighted and shall not be copied for use as erection plans
or shop details. Use of JVA's electronic files as the basis for shop drawings requires
prior approval by JVA, a signed release of liability by the General Contractor and/or
his subcontractors, and deletion of JVA's name and logo from all sheets so used.
The General Contractor shall submit in writing any requests to modify the
Structural Drawings or Project Specifications.
All shop and erection drawings shall be checked and stamped (after having been checked)
by the General Contractor prior to submission for Structural Engineer's review;
shop drawing submittals not checked by the General Contractor prior to submission to
the Structural Engineer will be returned without review.

prior to fabrication for plant fabricated wood joists, pre-engineered wood trusses.
Submit in a timely manner to permit 10 working days for review by the
Structural Engineer.
Shop drawings submitted for review do not constitute request for change in writing"
unless specific suggested changes are clearly marked. In any event, changes made by
means of the shop drawing submittal process become the responsibility of the one
initiating the change.
_____________________________________________________________________________________________
FIELD VERIFICATION OF EXISTING CONDITIONS:
The General Contractor shall thoroughly inspect and survey the existing structure to
verify conditions that affect the work shown on the drawings.
The General Contractor shall report any variations or discrepancies to the Architect and
Structural Engineer before proceeding.
_____________________________________________________________________________________________
STRUCTURAL ERECTION AND BRACING REQUIREMENTS:
The Structural Drawings illustrate and describe the completed structure with elements in
their final positions, properly supported, connected, and/or braced.
The Structural Drawings illustrate typical and representative details to assist the
General Contractor. Details shown apply at all similar conditions unless otherwise
indicated. Although due diligence has been applied to make the drawings as complete as
possible, not every detail is illustrated and not every exceptional
condition is addressed.
All proprietary connections and elements shall be installed in accordance with the
manufacturers' recommendations.
All work shall be accomplished in a workmanlike manner and in accordance with the
applicable codes and local ordinances.
The General Contractor is responsible for coordination of all work, including layout
and dimension verification, materials coordination, shop drawing review, and the work
of subcontractors. Any discrepancies or omissions discovered in the course of the work
shall be immediately reported to the Architect and Structural Engineer for resolution.
Continuation of work without notification of discrepancies relieves the Architect and
Structural Engineer from all consequences.
Unless otherwise specifically indicated, the Structural Drawings do not describe methods
of construction.
The General Contractor, in the proper sequence, shall perform or supervise all work
necessary to achieve the final completed structure, and to protect the structure,
workmen, and others during construction. Such work shall include, but not be limited to
temporary bracing, shoring for construction equipment, shoring for excavation, formwork,
scaffolding, safety devices and programs of all kinds, support and bracing for cranes
and other erection equipment.
Do not backfill against basement or retaining walls until supporting slabs and floor
framing are in place and securely anchored, unless adequate temporary bracing
is provided.
Temporary bracing shall remain in place until all floors, walls, roofs and any other
supporting elements are in place.
The Architect and Structural Engineer bear no responsibility for the above items, and
observation visits to the site do not in any way include inspections of these items.
These plans have been engineered for construction at one specific building site.
Builder assumes ALL responsibility for use of these plans at ANY OTHER building site.
Plans shall not be used for construction at any other building site without specific
review by the engineer.
_____________________________________________________________________________________________
PRECAUTIONARY NOTES ON STRUCTURAL BEHAVIOR:
Interior architectural finish detailing must accommodate the relative differential
movements of supporting structural elements.
Where the roof framing element spans are long, applied loading will naturally cause
substantial deflection. Interior elements hung from the roof structure will deflect
with the roof.
The floor is a floating concrete slab-on-grade and may experience movements independent
of the structural foundations. Interior elements supported on the slab-on-grade floor
will move with the floor. Interior elements supported on foundations and columns will
not experience similar or measurable movements.
Exterior/perimeter wall assemblies hung from the edge of the building structure will be
directly affected (to some degree) by changes in external temperature and
floor deflection.
Exterior/perimeter and interior architectural finish details should allow for relative
movements between elements with different support conditions.
