1.Dimensions:
Written dimensions take precedence over scaled dimensions.All dimensions noted within the Structural Drawings shall be verified with the
Architectural Drawings. Refer to Mechanical,Electrical,Plumbing,and Architectural Drawings for openings not noted within the Structural
Drawings.Any dimensional discrepancies shall be noted in writing for review by the Architect and Structural Engineer.
2.Shop Drawings:
Shop drawings shall be prepared by the fabricator.Copying of these Construction Documents for use as shop drawings will not be permitted.
3.Field Verification:
The Contractor shall verify existing conditions prior to commencement of work,and shall notify the Architect and Structural Engineer for any
interpretation or clarification. These construction documents were prepared with information about the existing building provided
by others. Limited investigation of the existing structure was undertaken. If the Contractor discovers existing conditions
which vary from those shown on these documents he shall notify the Architect and Structural Engineer immediately for further
clarification.
4. Field Modifications to Structural Members:
The Contractor is responsible for securing the Architect's and Structural Engineer's approval prior to any cutting,notching,drilling or other
modifications which may affect the integrity of the structure.When such modifications have been approved,they are to be completed in accordance
with applicable building codes and manufacturer's instructions.
5. Duty of Cooperation:
Issuance of these documents presupposes further cooperation among the Owner,Contractor,Architect and Structural Engineer. Building design
and construction are complex,and every contingency cannot be anticipated.Although the Structural Engineer(s)have performed their services with
due care and diligence,they cannot guarantee perfection.Any ambiguity or discrepancy discovered through the use of these documents shall be
promptly reported to the Architect and Structural Engineer for further clarification.Failure to do so may compound misinterpretation and increase
construction costs,and such failure shall relieve the Structural Engineer of responsibility from consequences which may arise.
6.Changes to the Work:
Substitution of noted structural products or"approved equivalent"products will be acceptable only with the written approval of the Structural
Engineer. Changes to the Contract Documents made without approval are unauthorized and shall relieve the Structural Engineer of responsibility
from consequences which may arise.
7.Jobsite Safety:
These drawings do not include the necessary components for construction safety.The General Contractor shall provide for the jobsite safety of all
personnel,work,materials,utilities,equipment and adjacent properties in accordance with accepted codes,regulations and industry practices.
STRUCTURAL TIMBER:
1.Structural Timber has been designed and shall be constructed in conformance with provisions of the NDS Specification for Stress Grade Lumber
and its Fastenings.The Contractor shall not cut,notch,or otherwise modify timber members without the written consent of the Structural engineer.
Provide cross-bridging at 8'-o"o.c.maximum,and provide solid blocking between joists at all bearing supports.
2.Framing Lumber(minimum requirements)shall be as follows:
A. Wall Studs Hem-Fir(HF)Construction Grade
B. Roof Rafters(2x members) Hem-Fir(HF)#2 Grade or Better
D. Roof Beams Douglas-Fir(DF)#1 Grade Beam&Stringer
3.Wall,roof,and floor sheathing shall meet the minimum requirements of the APA and AITC. Provide thicknesses and fasten to framing members
as noted in the Structural Drawings. Panels are to be oriented to span along their strong axis,and all panel joints are to be staggered.
4. Pre-fabricated structural connectors shall be as manufactured by Simpson Strong-Tie Company;Pleasanton,California or approved equivalent.
5. Laminated Veneer Lumber(LVL)shall be as manufactured by Boise Cascade Corporation or approved equivalent. Provide member size as noted
in the Structural Drawings(Fb=2,800 psi minimum).Refer to the Manufacturer Installation Guide for further construction requirements.
SPECIAL INSPECTIONS:
1.It is the responsibility of the Contractor to coordinate all structural inspections as required by governing building codes and the Construction
Documents.A qualified independent testing company is to provide Special Inspections for portions of the Work,as indicated in the Construction
Documents and as required by local jurisdictions.
2.The Special Inspector shall be responsible for completing,maintaining,and resubmitting all special inspection logs and forms required by Local
Building Officials.
