CODE REQUIREMENTS: All design and construction shall conform to the requirements of the
Uniform Building Code, 1979 edition.
DESIGN LOADS: In addition to the dead loads, the following live loads were used for design:
AASHTO H-20 Truck Loads.
Concrete members were designed by ultimate strength methods.
SHOP DRAWINGS: If fabricator's shop drawings differ in design or add to the design of the
structural drawings, they shall bear the seal and signature of a Washington State Registered
Structural Engineer. Design drawings and calculations for fabrication shall bear the seal and
signature of a Washington State Registered Structural Engineer. Seal and signature are to be
affixed prior to submission of drawings and calculations to the Owner. All shop drawings shall be
submitted to the Owner for approval prior to any construction. The General Contractor shall
Y) review and approve shop drawings before submittal to Owner.

REINFORCING STEEL: Unless otherwise noted, all reinforcing steel shall be deformed bars in
accordance with ASTM specification A-615, of the sizes shown on the drawings and the grades
shown below.
Use Grade fs fy (psi)

Any bars to be field bent 40 20,000 40,000
Reinforcing steel shall be securely tied in place with # 16 double annealed iron wire. Bars in
beams and slabs shall be supported on well -cured concrete blocks or approved metal chairs as
specified by the CRSI Manual of Standard Practice, MSP-I-76. Reinforcing steel shall be
detailed in accordance with the "ACI Manual of Standard Practice for Detailing Reinforced
Concrete Structures", ACI 315-74. Detail drawings shall be prepared and submitted to the Owner
for approval prior to fabrication. Lap all reinforcing bars as shown on schedules. A minimum lap
for all bars shall be ('-6' Mill test reports for Grade 60 bars shall be submitted to the Owner
prior to placing concrete. Welding of reinforcing steel shall be performed using low hydrogen
electrodes, and in accordance with AWS D12.1-75 Reinforcing Steel Welding Code.
