About this file
This is a construction drawing package for the Unit 4 Cell 5 Earthwork project at Twin Chimneys Landfill, a municipal solid waste facility operated by Greenville County, South Carolina. The project involves excavation of approximately 160,000 cubic yards of soil and rock material across 12.5 acres to create a new landfill cell. Key project components include removal and stockpiling of excavated materials in designated on-site locations (clay soils north of Cell 4, rock at the cell tower stockpile, and miscellaneous soils west of Cell 4), decommissioning of the temporary sediment basin by removing and grouting the existing barrel, installation of nine gabion baskets (six measuring 6 feet long by 4.5 feet wide by 3 feet high and three measuring 6 feet long by 4.5 feet wide by 3 feet high), placement of 2,000 square yards of erosion control matting, and seeding of 12 acres of disturbed areas. The contractor is responsible for providing pre-construction and as-built surveys signed by a licensed land surveyor to establish baseline and final earthwork quantities. A non-mandatory pre-proposal meeting is scheduled for January 14, 2026, at 10:30 AM, with questions due by January 19, 2026, at 5:00 PM, and proposals due electronically by February 9, 2026, at 3:00 PM. Contract award is anticipated on February 20, 2026, with a targeted Notice to Proceed on March 16, 2026, and a substantial completion timeline of 150 days.
The drawings indicate existing site conditions, proposed grading and excavation limits, stockpile locations, and stormwater management details. Access to the site shall be via the existing construction entrance on Augusta Road (Highway 25), with restricted access to Bridge Road requiring coordination with the landfill operator and traffic control during operating hours. Contractors must protect all existing wells, structures, and utilities and are responsible for maintaining erosion and stormwater control measures, including sediment basins A, 10, and 11, which require cleanout at least twice during the contract period. Special provisions address rock blasting, permitted only on weekdays between 5 PM and 6:30 PM, with rock larger than 3 cubic yards to be reduced before stockpiling and boulders removed to the cell tower stockpile. Rock encountered on 3:1 slope faces shall not be covered with soil or seeded, while all other excavation, fill, and stockpile areas require seeding prior to completion. The contractor must maintain security of all tools, materials, and equipment on site and manage stormwater runoff to prevent contamination of existing cells 1, 2, and 3.

● OUTSIDE THE LIMITS OF UNIT 1, 2, AND 4: FREELAND & ASSOCIATES AERIAL SURVEY DATED JULY 15, 2021.
3. THE DEBRIS (ROCK, VEGETATION, TREES) WITHIN THE WORK AREA MATERIAL SHALL BE STOCKPILED WITHIN THE UNIT 4
AREA AND OUTSIDE OF THE EXCAVATION AREA.
4. 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.
5. 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.
6. STOCKPILE ALL EXCAVATED SOIL MATERIALS, NOT USED IN THE WORK, IN THE DESIGNATED AREA INDICATED ON THE
SHEET 14C-03.

GENERAL CONSTRUCTION SEQUENCE:
1. ESTABLISH LIMITS OF CONSTRUCTION.
2. REMOVE AND STOCKPILE DEBRIS IN THE WORK AREA.
3. PERFORM INITIAL SURVEY.
4. REDIRECT STORMWATER FROM SEDIMENT BASIN A.
5. BEGIN EXCAVATION OF CELL 5. STOCKPILE EXCAVATED MATERIALS IN THE DESIGNATED STOCKPILES.
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.
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.

ROCK:
1. ROCK IS ANTICIPATED WITHIN THE UNIT 4 CELL 5 EXCAVATION. THE CONTRACTOR IS ALLOWED TO BLAST THE ROCK
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.
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.
8. ANY BOULDERS ENCOUNTERED DURING THE WORK SHALL BE REMOVED AND PLACED IN THE STOCKPILE NEAR THE
