PLAN NOTES:

1. CONTRACTOR TO VERIFY EXISTING CONDTIONS ON SITE PRIOR TO CONSTRUCTION.

EXISTING RTU FRAME SHOWN IS BASED ON THE STRUCTURAL DRAWINGS BY TOLAND &

MIZELL ARCHITECTS AND APPLIED ENGINEERING SOLUTIONS, INC. DATED JUNE 17, 2010.

2. THE PROPOSED NEW UNIT SHALL WEIGH NO MORE THAN 2500 lbs AND IT IS THE

RESPONSIBILITY OF THE CONTRACTOR TO VERIFY THE BEARING LOCATIONS OF THE NEW

UNIT PRIOR TO INSTALLATION.

3. ALL NEW STEEL SHALL BE HOT DIPPED GALAVANIZED AND THEN TOUCHED UP AS NEEDED

IN THE FIELD AFTER INSTALLATION.

4. THE BAR GRATING SHALL MATCH THE EXISTING, 1” x 3/16” ATTACHED TO THE FRAMING WITH

¼” SADDLE CLIPS.

5. NO EXISTING BRACING SHALL BE REMOVED WITHOUT THE WRITTEN CONSENT OF THE

STRUCTURAL ENGINEER UNLESS SHOWN ON THE DRAWINGS.

6. ALL FIELD WELDS SHALL BE TOUCHED WITH GALVANIZING PER GENERAL NOTES.

7. REMOVE EXISTING GRATING AS NEEDED TO INSTALL NEW UNIT.

SUBSTITUTIONS, SUBMITTALS, AND RFI'S

1. CONTRACTOR SHALL SUBMIT ALL SUBSTITUTIONS FOR APPROVAL PRIOR TO

CONSTRUCTION WITH THE FOLLOWING INFORMATION:

2. SHOP DRAWING SUBMITTALS SHALL BE SUBMITTED BY THE GENERAL CONTRACTOR IN A

TIMELY MANNER TO PROVIDE AN ADEQUATE AMOUNT OF TIME FOR REVIEW.

A. REVIEW BY STRUCTURAL ENGINEER OF RECORD WILL BE FOR GENERAL COMPLIANCE

WITH THE CONTRACT DOCUMENTS AND CONFORMANCE WITH THE DESIGN CONCEPT.

THIS REVIEW DOES NOT IN ANYWAY RELIEVE THE CONTRACTOR AND/OR THE

CONTRACTOR'S SUBCONTRACTORS FROM RESPONSIBILITY FOR ERRORS OR DEVIATIONS

FROM THE CONTRACT REQUIREMENTS. THE CONTRACTOR IS RESPONSIBLE FOR ALL

DIMENSIONS, PROPER FIT, QUALITIES OF THE MATERIALS, AND COORDINATION WITH

OTHER TRADES AND SUPPLIERS.

3. REQUESTS FOR INFORMATION (RFI'S) SHALL BE SUBMITTED IN A TIMELY MANNER WHEN

INFORMATION IS MISSING FROM THE CONSTRUCTION DOCUMENTS, INFORMATION IS

CONFLICTING WITHIN THE CONSTRUCTION DOCUMENTS, OR IS AMBIGUOUS.

A. THE CONTRACTOR MUST USE DUE DILIGENCE IN ATTEMPING TO FIND ANY ANSWER

PRIOR TO SUBMITTING AN RFI.

B. IF THE INFORMATION REQUESTED IN AN RFI IS APPARENT FROM FIELD OBSERVATION, IS

CONTAINED IN THE CONSTRUCTION DOCUMENTS, OR IS REASONABLY INFERABLE FROM THE

CONSTRUCTION DOCUMENTS, THE CONTRACTOR SHALL BE RESPONSIBLE TO THE OWNER

FOR ALL REASONABLE COSTS CHARGED RELATED TO ADDITIONAL SERVICES INCURRED

DUE TO ANSWERING THE RFI.

CONSTRUCTION AND SAFETY

1. CONTRACTOR SHALL BRACE ENTIRE STRUCTURE AS REQUIRED TO MAINTAIN STABILITY

UNTIL COMPLETE AND FUNCTIONING AS THE DESIGNED UNIT.

2. ENGINEER SHALL NOT BE RESPONSIBLE FOR THE MEANS, METHODS, TECHNIQUES,

SEQUENCES OR PROCEDURES OF CONSTRUCTION SELECTED BY CONTRACTOR.

3. THE CONTRACTOR WILL BE SOLELY AND COMPLETELY RESPONSIBLE FOR CONDITIONS OF

THE JOB SITE INCLUDING SAFETY OF ALL PERSONS AND PROPERTY DURING PERFORMANCE OF

THE WORK. THIS REQUIREMENT WILL APPLY CONTINUOUSLY AND NOT BE LIMITED TO NORMAL

WORKING HOURS. WHEN ON SITE, THE ENGINEER IS RESPONSIBLE FOR HIS OWN SAFETY BUT

HAS NO RESPONSIBILITY FOR THE SAFETY OF OTHER PERSONNEL OR SAFETY CONDITIONS AT

THE SITE.

STRUCTURAL STEEL

1. ALL DETAILING, FABRICATION, AND ERECTION SHALL CONFORM TO AISC SPECIFICATIONS

FOR "DESIGN, FABRICATION, AND ERECTION OF STRUCTURAL STEEL FOR BUILDINGS", AND

THE AISC "CODE OF STANDARD PRACTICE FOR STEEL BUILDINGS AND BRIDGES", LATEST

EDITION.

2. NO OPENING OR HOLE SHALL BE PLACED IN ANY STRUCTURAL MEMBER (OTHER THAT WHAT

IS INDICATED ON THE DRAWINGS) UNLESS THE LOCATION HAS BEEN APPROVED IN WRITING BY

THE STRUCTURAL ENGINEER.

3. ALL FLOOR OR ROOF BEAMS SHALL BE FABRICATED WITH THE NATURAL CAMBER UP.

4. FIELD CONNECTIONS SHALL BE BOLTED EXCEPT WHERE WELDED CONNECTIONS ARE

INDICATED ON THE STRUCTURAL DRAWINGS.

5. WELDING SHALL BE IN ACCORDANCE WITH THE AMERICAN WELDING SOCIETY (AWS D1.1).
