Attached to: Dalecarlia Backwash Water Tanks Improvements
Solicitation number: W912DR21B0008
Issued by: Department of the Army Corps of Engineers Engineering District Baltimore

About this file

Written by GovTribe AI · Dec 28, 2023

This federal solicitation seeks improvements to wash water storage tanks and related infrastructure at the Dalecarlia Water Treatment Plant. The Washington Aqueduct, a division of the Baltimore District US Army Corps of Engineers, treats and distributes drinking water to Washington D.C. and surrounding areas. Two storage tanks at the Dalecarlia plant store backwash water for filter cleaning - an underground tank and an elevated tank. Both supply lines and waste recycling systems require upgrades to address deficiencies, restore reliability, and comply with environmental permits. Modifications are needed to the altitude valve supplying the tanks, 24-inch and 30-inch cast iron mains, and the subsurface backwash recovery pumping station with its two centrifugal pumps. The solicitation aims to improve wash water storage and handling capabilities at the critical Dalecarlia Water Treatment Plant.

1. UNDERGROUND UTILITIES ARE SHOWN FOR THE CONVENIENCE OF THE

CONTRACTOR ONLY.

THE CONTRACTOR SHALL CONTACT ALL UTILITY OWNERS AND CONFIRM

LOCATIONS OF UTILITIES AT LEAST 48 HOURS BEFORE BEGINNING

CONSTRUCTION. THE CONTRACTOR SHALL ACCURATELY LOCATE AND

UNCOVER ALL EXISTING UTILITIES BEFORE BEGINNING CONSTRUCTION. ANY

DAMAGE RESULTING FROM THE CONTRACTOR'S OPERATIONS SHALL BE

REPAIRED AT THE CONTRACTOR'S EXPENSE. WHERE CROSSING OF

EXISTING UTILITIES OCCUR, PROVIDE 12" MINIMUM CLEARANCE EXCEPT

WATER MAINS SHALL BE 18". CROSS UNDER ALL WATER MAINS WHERE IT IS

NOT POSSIBLE TO PROVIDE 18" CLEARANCE.

2. SEWER AND WATER SERVICE SHALL BE MAINTAINED DURING ENTIRE

CONSTRUCTION PERIOD OR TEMPORARY FACILITIES PROVIDED.

3. MINIMUM COVER OVER PIPING SHALL BE 48", BELOW FINISHED GRADE

UNLESS OTHERWISE SHOWN OR SPECIFIED.

4. IF UNSATISFACTORY MATERIAL FOR ADEQUATE BEARING IS

ENCOUNTERED AT THE NORMAL SUBGRADE, THE UNSATISFACTORY

MATERIAL SHALL BE REMOVED AND REPLACED WITH SUITABLE

FOUNDATION STABILIZATION MATERIAL AS SPECIFIED.

5. THE CONTRACTOR SHALL NOT DISTURB AREAS OUTSIDE THE IDENTIFIED

LIMITS OF DISTURBANCE.

GENERAL NOTES:

CONSTRUCTION NOTES:

1. LAY PIPE TO UNIFORM GRADE BETWEEN INDICATED ELEVATION POINTS.

2. SIZE OF FITTINGS SHOWN ON PLANS SHALL CORRESPOND TO ADJACENT

STRAIGHT RUN OF PIPE, UNLESS OTHERWISE INDICATED. TYPE OF JOINT

AND FITTING MATERIAL SHALL BE THE SAME AS SHOWN FOR ADJACENT

STRAIGHT RUN OF PIPE.

3. LOCATION AND NUMBER OF PIPE HANGERS AND PIPE SUPPORTS SHOWN

IS ONLY APPROXIMATE. FINAL SUPPORT REQUIREMENTS SHALL BE

DETERMINED BY THE CONTRACTOR.

4. ALL JOINTS SHALL BE WATERTIGHT. WALL PIPES SHALL BE USED

WHEREVER PIPING PASSES FROM A STRUCTURE TO BACKFILL.

5. ALL FLEXIBLE CONNECTORS OR FLANGED COUPLING ADAPTERS SHALL BE

PROVIDED WITH THRUST TIES, OR ANCHORS, UNLESS OTHERWISE NOTED.

6. SYMBOLS, LEGENDS, AND PIPE USE IDENTIFICATIONS SHOWN SHALL BE

FOLLOWED THROUGHOUT THE PLANS, WHEREVER APPLICABLE.

NOT ALL OF THE VARIOUS PIPING COMPONENTS ARE NECESSARILY

USED IN THE PROJECT.

1. FACILITIES ARE SHOWN HEAVY LINED. SCREENING IS USED TO IN ORDER

TO CLARIFY DRAWINGS. FOR EXAMPLE, STRUCTURES ARE SCREENED ON

MECHANICAL DRAWINGS TO HIGH-LITE EXISTING.

2. DEMOLITION WORK IS SHOWN BY DEPICTING FACILITIES, EQUIPMENT,

PIPING, ETC. TO BE REMOVED AS CROSS HATCH.

3. ALL DIMENSIONS FOR EQUIPMENT PROVIDED IN THIS CONTRACT TO

BE VERIFIED BY CONTRACTOR.

4. REFER TO STRUCTURAL, MECHANICAL, ELECTRICAL AND OTHER DISCIPLINES

OF DRAWINGS FOR ADDITIONAL NOTES.

CONSTRUCTION SPECIFICATIONS

1. PLACE STABILIZED CONSTRUCTION ENTRANCE (SCE) IN ACCORDANCE WITH THE APPROVED PLAN. VEHICLES MUST

TRAVEL OVER THE ENTIRE LENGTH OF THE SCE. USE MINIMUM LENGTH OF 50 FEET (*30 FEET FOR SINGLE

RESIDENCE LOT). USE MINIMUM WIDTH OF 10 FEET. FLARE SCE 10 FEET MINIMUM AT THE EXISTING ROAD TO

PROVIDE A TURNING RADIUS.

2. PIPE ALL SURFACE WATER FLOWING TO OR DIVERTED TOWARD THE SCE UNDER THE ENTRANCE, MAINTAINING

POSITIVE DRAINAGE. PROTECT PIPE INSTALLED THROUGH THE SCE WITH A MOUNTABLE BERM WITH 5:1 SLOPES AND

A MINIMUM OF 12 INCHES OF STONE OVER THE PIPE. PROVIDE PIPE AS SPECIFIED ON APPROVED PLAN. WHEN THE

SCE IS LOCATED AT A HIGH SPOT AND HAS NO DRAINAGE TO CONVEY, A PIPE IS NOT NECESSARY. A MOUNTABLE

BERM IS REQUIRED WHEN SCE IS NOT LOCATED AT A HIGH SPOT.

3. PREPARE SUBGRADE AND PLACE NONWOVEN GEOTEXTILE, AS SPECIFIED IN SECTION H-1 MATERIALS.

4. PLACE CRUSHED AGGREGATE (2 TO 3 INCHES IN SIZE) OR EQUIVALENT RECYCLED CONCRETE (WITHOUT REBAR) AT

LEAST 6 INCHES DEEP OVER THE LENGTH AND WIDTH OF THE SCE.

5. MAINTAIN ENTRANCE IN A CONDITION THAT MINIMIZES TRACKING OF SEDIMENT. ADD STONE OR MAKE OTHER

REPAIRS AS CONDITIONS DEMAND TO MAINTAIN CLEAN SURFACE, MOUNTABLE BERM, AND SPECIFIED DIMENSIONS.

IMMEDIATELY REMOVE STONE AND/OR SEDIMENT SPILLED, DROPPED, OR TRACKED ONTO ADJACENT ROADWAY BY

VACUUMING, SCRAPING, AND/OR SWEEPING. WASHING ROADWAY TO REMOVE MUD TRACKED ONTO PAVEMENT IS

NOT ACCEPTABLE UNLESS WASH WATER IS DIRECTED TO AN APPROVED SEDIMENT CONTROL PRACTICE.
