About this file
This is a contract drawings addendum document prepared by HDR Engineering, Inc. for Greenville County, South Carolina, detailing the Unit 4 Cell 5 Earthwork Construction project at Twin Chimneys Landfill. The project requires the excavation of approximately 185,000 cubic yards of cut material and 7,500 cubic yards of fill across 12.5 acres to develop a new municipal solid waste landfill cell. Excavated materials must be strategically stockpiled in designated areas: clay soils with hydraulic conductivity of 1E-5 cm/sec or less in the existing clay stockpile north of Cell 4, rock materials in the cell tower stockpile, and miscellaneous soils in Unit 7 west of Cell 4. The project includes removal and stockpiling of tree debris and rock piles, decommissioning of a temporary sediment basin by removing the riser, barrel, and skimmer, installation of gabion baskets, placement of 2,000 square yards of erosion control blankets, and seeding of 12 acres of disturbed areas. Contractors must provide a pre-construction survey and as-built survey signed and sealed by a licensed land surveyor to establish baseline and final payment quantities. The non-mandatory pre-proposal meeting was scheduled for January 14, 2026, with a question submission deadline of January 19, 2026, at 5:00 PM and proposal submissions due by February 9, 2026, at 3:00 PM. The county anticipated contract award on February 20, 2026, with a Notice to Proceed targeted for March 16, 2026, and a substantial completion timeline of 150 days.
Contractors must demonstrate experience by completing at least two similar projects within the last five years and must submit a Bid Bond equal to 5 percent of the bid price along with Performance and Payment Bonds equal to the total bid price within 15 working days of award. Insurance requirements include $1,000,000 General Liability per occurrence, $1,000,000 Automobile Liability, Statutory Worker's Compensation, $1,000,000 Umbrella/Excess Liability, and $1,000,000 Professional Errors and Omissions, with Greenville County named as an additional insured. Liquidated damages are assessed at approximately $1,000 per day for substantial completion and $500 per day for final completion. The evaluation criteria are equally weighted at 20 percent each, assessing responsiveness to the RFP, proposed project schedule, similar project experience, cost, and equipment specifications. No specific budget range is disclosed in the contract documents, and no set-aside designations for disadvantaged enterprises are identified. Rock blasting is permitted weekdays between 5:00 PM and 6:30 PM, with the contractor responsible for protecting all personnel and equipment and for immediately notifying the engineer if springs or other non-perched water sources are encountered.

● OUTSIDE THE LIMITS OF UNIT 1, 2, AND 4: FREELAND & ASSOCIATES AERIAL SURVEY DATED JULY 15, 2021.
2. THE DEBRIS (ROCK, VEGETATION, TREES) WITHIN THE WORK AREA MATERIAL SHALL BE STOCKPILED WITHIN THE UNIT 4
AREA AND OUTSIDE OF THE EXCAVATION AREA.
3. CONTRACTOR SHALL PROVIDE A PRE-CONSTRUCTION SURVEY (ELECTRONIC AND SIGNED AND SEALED BY A LAND SURVEYOR) OF THE WORK AREAS (AFTER THE DEBRIS IS STOCKPILED). THIS SURVEY SHALL ESTABLISH THE BASELINE
FOR FOR EARTHWORK QUANTITIES.
4. FOLLOWING COMPLETION OF THE WORK, CONTRACTOR SHALL PROVIDE AN AS BUILT SURVEY (ELECTRONIC AND SIGNED AND SEALED BY A LAND SURVEYOR) TO SERVE AS THE BASIS FOR FINAL PAYMENT OF EARTHWORK QUANTITIES.
5. STOCKPILE ALL EXCAVATED SOIL MATERIALS, NOT USED IN THE WORK, IN THE DESIGNATED AREAS. INDICATED ON THE
SHEET 14C-03.
· CLAY SOILS WITH HYDRAULIC CONDUCTIVITY OF 1E-5CM/SEC OR LESS (CLAYEY SOIL): EXISTING CLAY

GENERAL CONSTRUCTION SEQUENCE:
1. ESTABLISH LIMITS OF CONSTRUCTION.
2. REMOVE AND STOCKPILE TREE DEBRIS IN THE WORK AREA. ROCK PILES WITHIN THE WORK AREA SHALL BE HAULED
TO THE STOCKPILE NEAR THE CELL TOWER. ROCKS WITHIN THE WORK AREA MAY NEED TO BE REDUCED TO A
MANAGEABLE SIZE TO LOAD AND HAUL.
3. PERFORM INITIAL SURVEY OF THE CELL 5 AREA AND THE AREA IN UNIT 7 OF THE PROPOSED GRADES.
4. REDIRECT STORMWATER FROM SEDIMENT BASIN A.
5. BEGIN EXCAVATION OF CELL 5. STOCKPILE EXCAVATED MATERIALS IN THE DESIGNATED STOCKPILES. USE EXCAVATED
MATERIAL FOR STRUCTURAL FILL.
6. REMOVE THE RISER/BARREL/SKIMMER IN THE TEMPORARY SEDIMENT BASIN A AND GROUT THE BARREL
7. UPON COMPLETION OF CELL 5 EXCAVATION, PERFORM ASBUILT SURVEY OF CELL 5 AND THE AREA IN UNIT 7 OF
EXCAVATED SOIL FROM CELL 5.
8. INSTALL THE GABION BASKETS.
9. CLEANOUT SEDIMENT BASINS #10 AND #11.
OVERALL PROJECT SCOPE:
THE COUNTY IS CURRENTLY GRADING THE AREA SOUTH OF CELL 5. THIS PROJECT IS TO EXCAVATE THE CELL 5 AREA TO THE GRADES SHOWN IN THESE DRAWINGS. THE TEMPORARY SEDIMENT BASIN A COLLECTS STORMWATER FROM CELLS 2, 3, AND 4 AS WELL AS FLOW FROM THE AREA WEST OF CELL 5. CONTRACTOR TO MAKE PROVISIONS TO REDIRECT FLOW OUT OF THE WORK
AREA. IT IS ANTICIPATED THERE WILL BE 3 TYPES OF MATERIAL EXCAVATED.

FOR REMOVAL. BLASTING MAY OCCUR WEEKDAYS BETWEEN 5 PM AND 6:30 PM. CONTRACTOR IS RESPONSIBLE FOR PROTECTING ALL PERSONNEL AND EQUIPMENT FROM DAMAGE RESULTING FROM BLASTING. CONTRACTOR TO BACKFILL WITH SOIL FROM THE SURROUNDING EXCAVATION. THE BACKFILL SHALL BE COMPACTED AS STRUCTURAL
FILL.
2. WHERE BLASTING IS PERFORMED, BLASTING SHALL BE DESIGNED TO FRACTURE ROCK TO ELEVATION AT LEAST 5
FEET BELOW DESIGN GRADES.
3. ENGINEER OR CQA SHALL BE ON SITE TO VERIFY & CONFIRM AREA AND DEPTH PRIOR TO BLASTING.
4. ROCK LARGER THAN 3 CY, SHALL BE REDUCED TO LESS THAN 3 CY BEFORE STOCKPILING. ROCK SMALLER THAN 3CY
SHALL BE STOCKPILED IN THE DESIGNATED LOCATIONS.
5. NOTIFY THE ENGINEER IMMEDIATELY AND STOP WORK IN THE VICINITY, IF THE CONTRACTOR ENCOUNTERS A SPRING
OR OTHER NON PERCH SOURCE OF WATER.
6. CONTROL STORMWATER RUNOFF AT ALL TIMES DURING THE WORK. PREVENT STORMWATER FROM RUNNING OFF THE
WORK AND INTO AREAS THAT DON'T DIRECTLY LEAD TO SEDIMENT BASINS. CONTRACTOR SHALL TAKE IMMEDIATE
ACTION TO PREVENT STORMWATER FROM ENTERING CELLS 1, 2 AND 3.
7. ROCK ENCOUNTERED ON THE 3:1 SLOPE FACE SHALL NOT BE COVERED WITH SOILS NOR SEEDED. ALL OTHER EXCAVATION, FILL AND STOCKPILE AREAS ARE REQUIRED TO BE SEEDED PRIOR TO COMPLETION OF THE WORK.
