NOTES

1. EXISTING CONDITIONS WITHIN THE CELL 3 DO NOT

REPRESENT THE JULY 15, 2021 SURVEY DUE TO

EXCAVATION. CONTRACTOR TO VERIFY CONDITIONS

PRIOR TO INITIATING CONSTRUCTION.

2. PROPOSED CONTOURS WITHIN

CONSTRUCTION BASELINE REPRESENT

SUBGRADE OF MSW CELL 3.

3. AN ACCEPTABLE PROOF ROLL (AS DEFINED

BY THE CQA CONSULTANT) MUST BE

OBSERVED TO DEMONSTRATE A STABLE

SUBGRADE PRIOR TO CONSTRUCTION OF

THE LINER SYSTEM. THE SUBGRADE MAY

BE ACCEPTED IN STAGES TO FACILITATE

CONSTRUCTION. REFER TO TECHNICAL

SPEC SECTION 31 38 10.

4. REFER TO SPECIFICATIONS AND CQA PLAN FOR

SURVEYING REQUIREMENTS TO PRODUCE AS-BUILT

DRAWINGS AND TO PROVIDE BASIS FOR VERIFYING

EXCAVATION QUANTITIES.

5. REMOVE ALL WET AND SOFT SOILS PRIOR TO

BEGINNING STRUCTURAL FILL PLACEMENT. COMPACT

PER SPECIFICATIONS. "BRIDGE LIFTS" REQUIRE

APPROVAL OF ENGINEER AND CQA CONSULTANT.

6. PROTECT EXISTING WELLS, DROP INLETS AND OTHER

STRUCTURES DURING THE WORK.

7. IF CONTRACTOR ENCOUNTERS GROUNDWATER

DURING EXCAVATION, IMMEDIATELY STOP WORKING IN

THAT AREA AND NOTIFY ENGINEER. EXISTENCE OF

WATER MAY REQUIRE REVISION TO GRADING. THE

CONTRACTOR SHALL IMPLEMENT ALL CHANGES BASED

ON EXISTENCE OF GROUNDWATER IN THE

EXCAVATION.
