WORKING IN THE AREA.

1.27 THESE CONTRACT DRAWINGS HAVE BEEN PREPARED BASED ON AN ABOVE-GROUND SURVEY. THE

EXISTING UNDERGROUND UTILITIES SHOWN ARE BASED ON AS-BUILT INFORMATION PROVIDED BY

THE USIBWC. THE BEST EFFORT HAS BEEN MADE TO DEPICT THESE UTILITIES, BUT THESE

LOCATIONS SHALL BE CONSIDERED APPROXIMATE. THERE MAY BE ADDITIONAL UNDERGROUND

UTILITIES NOT SHOWN ON THE CONTRACT DRAWINGS. IT SHALL BE THE RESPONSIBILITY OF THE

CONTRACTOR TO VERIFY EXISTENCE AND LOCATION OF ALL UTILITIES INCLUDING USE OF PRIVATE

UTILITY LOCATING SERVICE AND POTHOLING AS NECESSARY TO CONFIRM ALL UTILITIES PRIOR TO

CONSTRUCTION PER THE APPLICABLE SPECIFICATION REQUIREMENTS.

1.28 QUANTITIES SHOWN ON VARIOUS “QUANTITY SUMMARY TABLES” HEREIN SHALL BE CONSIDERED AS

INFORMATIONAL ONLY AND SHALL NOT SERVE AS THE BASIS OF THE CONTRACTORS BID. IT IS

EXPRESSLY UNDERSTOOD AND AGREED THAT THE QUANTITIES NOTED IN THESE TABLES ARE NOT

BY VIRTUE OF SUBMITTING A BID, A PART OF THE CONTRACT, AND REPRESENT ONLY AN OPINION BY

THE ENGINEER AS TO THE QUANTITIES SPECIFIC TO THAT TABLE. THE QUANTITY TABLES ARE

INCLUDED IN THE PLANS ONLY FOR THE CONVENIENCE OF BIDDERS AND THEIR USE IS SUBJECT TO

ALL THE CONDITIONS AND LIMITATIONS SET FORTH IN THE CONTRACT DOCUMENTS RELATING TO

THE EXAMINATION OF THE CONTRACT DOCUMENTS AND THE SUBMISSION OF A BID. SPECIFICALLY, SUBMISSION OF A BID SHALL BE CONCLUSIVE EVIDENCE THAT THE BIDDER HAS INVESTIGATED AND

IS SATISFIED AS TO THE CONDITIONS TO BE ENCOUNTERED, THE CHARACTER, QUALITY, AND SCOPE

OF WORK TO BE PERFORMED, THE QUANTITIES OF MATERIALS TO BE FURNISHED, AND THE

REQUIREMENTS OF THE CONTRACT DOCUMENTS. THE BIDDER IS CAUTIONED THAT IT IS HIS/HER

SOLE RESPONSIBILITY TO MAKE SUCH INDEPENDENT INVESTIGATION AND EXAMINATION AS THE

BIDDER DEEMS NECESSARY IN ORDER TO SATISFY HIS/HERSELF AS TO THE CONDITIONS TO BE

ENCOUNTERED IN THE PERFORMANCE OF WORK AND THE QUANTITIES REQUIRED TO COMPLETE

THE WORK IN ACCORDANCE WITH THE CONTRACT DOCUMENTS. THE BIDDER SHALL TAKE NO

ADVANTAGE OF ANY APPARENT ERROR OR OMISSION IN THE PLANS, BID SCHEDULE ITEMS,

ESTIMATED QUANTITIES NOTED IN THE SCHEDULE, SPECIFICATIONS OR OTHER CONTRACT

DOCUMENTS. IN THE EVENT THE BIDDER DISCOVERIES AN APPARENT ERROR OR OMISSION OR BE IN

DOUBT AS TO THEIR MEANING, THE BIDDER SHALL IMMEDIATELY NOTIFY THE USIBWC, IN WRITING, REQUESTING A CLARIFICATION OR INTERPRETATION. ANY CLARIFICATION AND OR INTERPRETATION

DEEMED APPROPRIATE BY THE USIBWC SHALL BE ISSUED TO ALL PROSPECTIVE BIDDERS IN THE

FORM OF AN ADDENDUM. ANY ADDENDUM SO ISSUED SHALL FORM A PART OF THE CONTRACT

DOCUMENTS.

1.28 NEITHER THE USIBWC NOR THE ENGINEER WARRANTS OR GUARANTEES THE RESULTS OF ANY

GEOTECHNICAL OR SUBSURFACE INVESTIGATIONS AS BEING REPRESENTATIVE OF THE SITE,

BEYOND THE ACTUAL LOCATION OF THE TEST SPECIMEN(S) AND ASSUMES NO RESPONSIBILITY FOR

THE MANNER IN WHICH THIS INFORMATION MAY BE USED OR THE CONCLUSIONS REACHED IN

UTILIZING THE INFORMATION AS PROVIDED IN THE CONTRACT DOCUMENTS. FURTHER, THE USIBWC

AND THE ENGINEER NEITHER WARRANTS OR GUARANTEES THE CONCLUSIONS REACHED,

RECOMMENDATIONS MADE OR TEST RESULTS PRESENTED AS PART OF THE GEOTECHNICAL OR

SUBSURFACE INVESTIGATION AS BEING REPRESENTATIVE OF THE ENTIRE SITE. IT SHALL BE THE

CONTRACTORS SOLE RESPONSIBILITY TO SUPPLEMENT ANY INFORMATION PROVIDED WITH

ADDITIONAL SUBSURFACE INVESTIGATIONS AND TESTING, AT THEIR SOLE EXPENSE IN ORDER TO

ASSURE THE INFORMATION PROVIDED IN THE CONTRACT DOCUMENTS IS REPRESENTATIVE OF THE

CONDITIONS TO BE ENCOUNTERED WITHIN THE LIMITS OF THE PROJECT AT THE TIME OF

KEYED DEMOLITION NOTES:

1. REMOVE, STORE AND REINSTALL WOODEN STAIRCASE.

2. REMOVE & REPLACE CHAIN LINK FENCE AND GATES AS

SHOWN.

3. REMOVE PORTION OF EXISTING BERM AS REQUIRED TO

CONSTRUCT ACCESS DRIVE.

4. EXCAVATE TO MINIMUM GRADES SHOWN TO CONSTRUCT

FLOODWALL STRUCTURE.

5. EXCAVATE TO THE MINIMUM GRADES SHOWN TO

CONSTRUCT PROPOSED C-B SLURRY WALL.

6. PERFORM BENCHING EXCAVATION AND EMBANKMENT

PLACEMENT TO ELEV. 120 FT ON RIVERSIDE SLOPES

PRIOR TO CONSTRUCTING C-B SLURRY WALL OR DRILLED

PIER FOUNDATIONS TO AVOID DISTURBING SOILS IN

CONTACT WITH SLURRY WALL OR DRILLED PIERS.

7. EXCAVATE FOR PROPOSED FLOODWALL DRAINAGE

BLANKET.

8. REFER TO TABLE ON SHEET G-005 ESTIMATE OF

QUANTITIES FOR DEMOLITION AND EXCAVATION.

GENERAL NOTES:

1. CONTRACTOR SHALL CONTACT "CALL BEFORE YOU DIG"

(1-800-245-4545) 48 HOURS PRIOR TO BEGINNING WORK AT ANY

LOCATION TO LOCATE UTILITIES WITHIN THE WORK ZONE.

2. TEMPORARY EXCAVATIONS ARE THE RESPONSIBILITY OF THE

CONTRACTOR, AND ARE SHOWN ONLY TO ILLUSTRATE MINIMUM

CRITERIA AND DESIGN INTENT. ACTUAL TEMPORARY EXCAVATION

DIMENSIONS ARE TO BE SUBMITTED BY CONTRACTOR FOR

ENGINEER'S APPROVAL. EXCAVATIONS SHALL MEET OSHA

CRITERIA, AND SLURRY TRENCH EXCAVATIONS MUST PROVIDE A

MINIMUM FACTOR OF SAFETY = 1.2.

3. DRILLED PIER INSTALLATION MAY NOT COMMENCE UNTIL

COMPLETION OF CEMENT-BENTONITE SLURRY WALL (SEE

SPECIFICATION SECTIONS 31 63 29 & 31 56 13).

4. CONTRACTOR SHALL REMOVE EXISTING CHAIN LINK FENCING

AND GATES (ALL WITH 3 STRAND BARBED WIRE) AND REPLACE

WITH NEW FENCING AND GATES TO MATCH EXISTING AND IN

ACCORDANCE WITH SPECIFICATION SECTION 32 31 13.

CONTRACTOR SHALL FIELD VERIFY LOCATIONS OF NEW FENCING

AND GATES WITH COR AND SUBMIT FOR COMPLIANCE
