6. Remove existing piping.

7. Pump out 3' of existing clearwell.

8. Cut holes into existing clearwell.

9. Clean area and Spot Disinfect.

10. Fill and Leak Test.

11. Put clearwell into service.

5. Coordinate with WTP to pump down existing clearwell.

6. Pump out 3' of existing clearwell.

7. Build Baffle Wall in existing clearwell.

8. Clean area and Spot Disinfect.

9. Fill and Leak Test.

10. Put clearwell into service.

11. Finish Grade Site.

12. Build Concrete Valley Gutter.

- The backwash pond will have water in it during construction. The contractor shall use every caution to not introduce this water into the work area. This would include scheduling the required pipe removals and installations that would breach the water when it will not harm the work area.

Another option could be draining the pond by pumping to remove the danger. No payment will be made for dewatering.

SCOPE:

THESE PLANS WERE PREPARED BY GEOMAT INC. OF FARMINGTON, NEW

MEXICO TO SHOW THE STRUCTURAL REQUIREMENTS FOR THE

CONSTRUCTION OF AN ADDITION TO THE CITY OF AZTEC CLEARWELL

LOCATED AT THE THE CITY OF AZTEC WATER TREATMENT PLANT IN AZTEC,

NEW MEXICO. ANY OTHER USE OF THESE PLANS IS PROHIBITED.

GEOMAT'S SCOPE OF SERVICES WAS LIMITED TO THE STRUCTURAL DESIGN

OF THE CLEARWELL ADDITION. ALL OTHER ASPECTS OF THE DESIGN SUCH

AS CONFIGURATION, OPENING LOCATIONS, PIPES, ELEVATIONS, ETC, ARE

ALL BY OTHERS.

THESE PLANS SHALL BE USED IN CONJUNCTION WITH THE CLEARWELL

DESIGN PLANS BY CHC ENGINEERS, LLC OF DURANGO, COLORADO. IF

THERE ARE DISCREPANCIES , THEY SHALL BE BROUGHT TO THE ATTENTION

OF THE DESIGN TEAM FOR RESOLUTION.

FOUNDATION:

A GEOTECHNICAL INVESTIGATION WAS PERFORMED BY GEOMAT

INC. OF FARMINGTON, NEW MEXICO. A REPORT IS AVAILABLE FROM

THE OWNER (GEOMAT PROJECT # 242-4907). THE CONTRACTOR

SHALL REVIEW THAT REPORT AND ABIDE BY THE

RECOMMENDATIONS MADE THEREIN.

SUBGRADE AND STRUCTURAL FILL PREPARATION

CONCRETE REINFORCED SLAB FOUNDATION AND RETAINING WALL

FOOTINGS SHOULD BEAR ON ENGINEERED FILL OR ON COMPACTED

NATIVE COBBLES AND GRAVELS, BUT NOT A COMBINATION OF THE

TWO MATERIALS.

IF THE STRUCTURAL SLAB IS TO BE SUPPORTED ON COMPACTED

NATIVE COBBLES AND GRAVEL, THE SURFACE OF THE NATIVE

GRAVELS AND COBBLES SHOULD BE PROOF COMPACTED UNDER

OBSERVATION BY A REPRESENTATIVE OF GEOMAT. DUE TO THE

ROCKY NATURE OF THE NATIVE GRAVELS AND COBBLES, PLACE A

THREE TO FOUR-INCH LEVELING COURSE OF OPEN-GRADED GRAVEL

OR COMPACTED BASE BETWEEN THE BOTTOM OF THE FOOTINGS

AND THE UNDERLYING COMPACTED COBBLES AND GRAVELS.

IF THE ANTICIPATED COBBLES AND GRAVEL ARE NOT

ENCOUNTERED, REPLACE THE LEVELING COURSE WITH

COMPACTED AGGREGATE BASE COURSE (ABC) FOR A DEPTH BELOW

THE FOOTING OF NOT LESS THAN ONE (1.0) FOOT FOR THE

CLEARWELL & 2'-0" MINIMUM FOR THE RETAINING WALL. THE ABC

SHOULD EXTEND BEYOND THE EDGES OF THE FOOTINGS AS

INDICATED IN THE GEOTECHNICAL REPORT.

IF ANY EXISTING FILL MATERIAL IS ENCOUNTERED DURING

EXCAVATIONS, THE FILL SHOULD BE COMPLETELY REMOVED FROM

BENEATH THE STRUCTURE AND REPLACED WITH ENGINEERED FILL.

STRUCTURAL FILL SHALL BE PLACED IN LIFTS NOT EXCEEDING 8

INCHES IN THICKNESS WHEN COMPACTED. PLACE FILL AT NEAR

OPTIMUM MOISTURE CONTENTS AND COMPACT TO A MINIMUM

OF 95% OF A MODIFIED PROCTOR (ASTM D1557).

IMPORTED OR EXISTING SOILS THAT CONFORM TO THE FOLLOWING

MAY BE USED FOR STRUCTURAL FILL:

GRADATION PERCENT FINER BY WEIGHT (ASTM C136)

3”

NO. 4 SIEVE.......................................................50-100

NO. 200 SIEVE...................................................50 MAX

STRUCTURAL FILL SHALL HAVE A MAXIMUM EXPANSIVE POTENTIAL

OF 1.5% MEASURED ON A SAMPLE COMPACTED TO

APPROXIMATELY 95 PERCENT OF THE ASTM D1557 MAXIMUM DRY

DENSITY AT ABOUT 3 PERCENT BELOW OPTIMUM WATER CONTENT

WHEN THE SAMPLE IS CONFINED UNDER A 144-PSF SURCHARGE

AND SUBMERGED.

AGGREGATE BASE COURSE SHALL CONFORM TO NMDOT TYPE I

SPECIFICATIONS.

ALL ASPECTS OF THE SUBGRADE PREPARATION, INCLUDING THE

EXCAVATION, COMPACTION, GRAVEL, BASE COURSE, BACKFILL,

AND ANY OTHER PREPARATION FOR PLACING THE CLEARWELL

SHALL BE CONSIDERED INCIDENTAL TO THE CONSTRUCTION OF THE

CONNECTION PIPE DETAIL KEYED NOTES:

THESE KEYED NOTES IN CONJUNCTION WITH DETAIL 8/S4 SUGGEST ONE

POSSIBLE WAY TO CONSTRUCT THE CONNECTION BETWEEN THE OLD AND

NEW CLEARWELLS. THE CONTRACTOR MAY ELECT TO USE A DIFFERENT

MEANS AND METHODS, BUT THE CONTRACTOR'S MEANS AND METHODS

MUST BE SUBMITTED IN DETAIL AND APPROVED BEFORE CONSTRUCTION

BEGINS.

1. REMOVE SOIL, LOOSE CONCRETE OR OTHER DEBRIS, FROM THE OUTSIDE OF

THE EXISTING CLEARWELL WALL. COAT WALL USED TO FORM NEW

CLEARWELL WALL WITH XYPEX SLURRY CONCENTRATE.

2. CONSTRUCT THE NEW CLEARWELL WALL.

2.1. INCLUDE XYPEX C500 SERIES IN THE MIX DESIGN IN ACCORDANCE WITH

THE MANUFACTURER'S RECOMMENDATIONS.

2.2. CAST A 3-FOOT HIGH x 3-FOOT WIDE OPENING CENTERED ON THE

LOCATION FOR THE PIPE.

2.3. CAST A 1" WIDE x 1 1/2" DEEP NOTCH AROUND THE PERIMETER OF THE 3x3 OPENING AS SHOWN.

2.4. PROVIDE ADDITIONAL REINFORCING AROUND THE OPENING SIMILAR TO

DETAIL 7/S4.

3. CUT THE HOLE IN THE OLD CLEARWELL WALL

3.1. CORE DRILL PILOT HOLES IN THE CORNERS OF PROPOSED OPENING.

3.2. SAWCUT THE OLD WALL TO OUTSIDE TANGENT OF CORE DRILLED HOLES

RESULTING IN A 3-FOOT HIGH x 3-FOOT WIDE OPENING IN THE OLD

CLEARWELL WALL.

3.3. REMOVE SAWCUT PORTION OF WALL, CLEAN DEBRIS

3.4. CUT A 1" WIDE x 1 1/2" DEEP NOTCH AROUND THE PERIMETER OF THE

OPENING.

3.5. ROUGHEN OPENING AND COAT W/ XYPEX SLURRY CONCENTRATE.

4. INSTALL 32" DIAMETER STUB PIPE THROUGH THE OPENING.

4.1. THOROUGHLY CLEAN & ROUGHEN THE OUTSIDE SURFACE OF PIPE AND

APPLY XYPEX CONCENTRATE SLURRY.

4.2. PLACE TWO CONSEAL CR-231 (OR EQUAL) WATERSTOPS AROUND THE

PIPE.

4.3. INSERT PIPE & WATERSTOPS THROUGH THE OPENING AND SUPPORT IN

PLACE WITH TEMPORARY SHORING.

5. SEAL THE OPENING

5.1. INSTALL XYPEX CONCENTRATE PATCH & PLUG AROUND THE PIPE IN

ACCORDANCE WITH MANUFACTURER'S RECOMMENDATIONS. (2" TO 3"

LIFTS FULL DEPTH)

* ELEVATIONS NOTES:

· THE TOP OF LID AND INVERT ELEVATIONS

SHOWN ARE BASED ON SURVEY INFORMATION

AVAILABLE AT THE TIME OF DESIGN.

· THE INTENT OF THE DESIGN IS TO MATCH THE

EXISTING TOP OF LID AND INVERT ELEVATIONS

WITH THE NEW CONSTRUCTION.

· IF THE ACTUAL ELEVATIONS DIFFER FROM

THOSE SHOWN, HOLD THE ACTUAL

ELEVATIONS.

· IF THE DIFFERENCE IS MORE THAN 2 INCHES,

NOTIFY THE DESIGN TEAM BEFORE

PROCEEDING.

CONNECTION PIPE NOTE:

THE CITY WILL REDUCE THE WATER LEVEL IN THE EXISTING

CLEARWELL TO FACILITATE THE MAKING OF THE CONNECTION

BETWEEN THE NEW AND THE OLD CLEARWELLS.

THE REDUCED WATER LEVEL CAN ONLY BE MAINTAINED FOR

48 HURS MAX.

THE CONTRACTOR SHALL PLAN TO WORK CONTINUOUSLY, 24

HOURS PER DAY, UNTIL THE CONNECTION IS COMPLETE AND

THE WATER LEVEL CAN BE RESTORED.
