About this file

Written by GovTribe AI · Apr 13, 2025

The provided file is a comprehensive set of bid drawings and technical specifications for the North Landfill Cell 1 Construction project by Larimer County, Colorado. The project involves constructing a new 20-acre municipal solid waste landfill cell with an engineered liner system, located at 15669 N County Road 9 in Wellington, CO. The bid is being accepted electronically through the Rocky Mountain E-Purchasing System, with key components including site clearing, grubbing, cell construction, grading, and revegetation of disturbed areas. The project drawings are dated July 2024, with bid documents issued for client review in March 2024, for Colorado Department of Public Health and Environment (CDPHE) review in June and July 2024, and formally issued for bidding on July 24, 2024.

The technical drawings provide extensive details about the landfill cell's construction, including bottom liner system specifications, leachate collection system, stormwater management, access roads, and perimeter berms. The project involves significant earthwork, with approximately 791,958 cubic yards of cut and 800,793 cubic yards of fill, including excavation for the bottom of liner, roadways, and cell 2 berm. The design includes a complex liner system with geosynthetic clay liner, HDPE geomembrane, drainage geocomposite, and protective cover layers. Additional infrastructure includes a leachate pump station, dual-contained forcemain, 26,000-gallon leachate storage frac tank, and multiple stormwater detention and control features. The project also incorporates environmental considerations such as monitoring well protection, seeding plans, and erosion control measures.

NOTES:

1. THE CONTRACTOR IS RESPONSIBLE FOR PERFORMING SURVEY PRIOR TO INITIATION OF

WORK. THE OWNER MAY ALSO PERFORM A SURVEY, THE OWNERS SURVEY IF

PERFORMED, WILL TAKE PRECEDENCE IN DETERMINING QUANTITIES. THE FINAL

DETERMINATION OF THE QUANTITIES WILL BE MADE BY THE ENGINEER BASED ON THE

SURVEYS.

2. THE CONTRACTOR IS RESPONSIBLE FOR CONSTRUCTING THE CELL, PERIMETER BERM,

ROAD, AND CHANNELS TO THE GRADES SHOWN ON THESE DRAWINGS. THE CONTRATOR

SHALL UTILIZE LASER EQUIPMENT FOR FINE GRADING BOTTOM OF LINER SYSTEM AND

SOIL LAYERS.

3. CONTOURS WITHIN THE CELL 1 EDGE OF LINER LIMITS REPRESENT BOTTOM OF LINER

SYSTEM.

4. THE ELEVATIONS SHOWN FOR THE PERIMETER ACCESS ROAD REPRESENT TOP OF ROAD

GRADE. PROVIDE CONSTANT SLOPE BETWEEN PERIMETER ROAD CONTROL POINTS.

5. EACH PANEL (PLANE) DEPICTS AN AREA OF CONSTANT GRADE. REFER TO THE DETAIL

DRAWINGS FOR BOTTOM OF LINER SYSTEM GEOMETRY AROUND THE PIPING AND

LEACHATE COLLECTION SYSTEM.

6. CONTROL POINTS 1-11 DEFINE THE TOE SLOPE, 13-23 DEFINE THE LOCATION OF THE EDGE

OF LINER, 24-32 DEFINE THE SUMP, AND 33-37 DEFINE THE BOTTOM OF THE PERIMETER

CHANNEL.

7. THE WORK SHALL BE CONSTRUCTED TO THE EDGE OF LINER LIMITS AND CONTROL GIVEN

ON THIS SHEET. IF THERE ARE ANY CONFLICTS BETWEEN INFORMATION ON THIS SHEET

AND OTHER REPRESENTATIONS AT THE WORK SITE, THE ENGINEER SHALL BE NOTIFIED.

THE ENGINEER WILL DETERMINE RESOLUTION OF CONFLICTS.

8. THICKNESS VERIFICATION SURVEY POINTS TO VERIFY THAT THE REQUIRED 12" OF

PREPARED SUBGRADE (SHEET 402) IS PLACED AT A FREQUENCY OF A MINIMUM OF 8

LOCATIONS PER ACRE. THESE THICKNESS VERIFICATION POINTS SHALL BE EXCLUSIVE OF

THE CONTROL POINTS SHOWN ON THIS SHEET.

WILL BE INSTALLED (GEOSYNTHETIC CLAY LINER, HDPE GEOMEMBRANE, AND DRAINAGE

GEOCOMPOSITE). AFTER THESE COMPONENTS ARE INSTALLED, THEN THE PROTECTIVE COVER

PLACEMENT CAN COMMENCE (SHEET C404).

2. CELL 1 CONTOURS WITHIN THE EDGE OF LINER LIMITS REPRESENT TOP OF BASEGRADE.

3. ANCHOR TRENCHES SHALL BE BACKFILLED WITH THE SAME MATERIAL AS USED FOR THE

PREPARED SUBGRADE.

4. THE EDGE OF LINER LIMITS GENERALLY REPRESENTS THE HORIZONTAL EXTENT OF THE LINER

SYSTEM. SEE LINER DETAILS.

5. CONTRACTOR TO CERTIFY IN WRITING TO THE ENGINEER THAT THE PREPARED SUBGRADE

MEETS SPECIFICATIONS INCLUDING THICKNESS VERIFICATION PRIOR TO INSTALLING

GEOSYNTHETICS.

6. GCL, HDPE LINER, AND GEOCOMPOSITE PANEL LAYOUTS SHALL BE SUBMITTED TO THE

ENGINEER FOR APPROVAL PRIOR TO INSTALLATION. THE PANELS SHALL BE SEAMED PARRALEL

TO LINE OF MAXIMUM SLOPE. FLOOR PANELS SHALL GENERALLY BE LAPPED ON THE DOWNHILL

SIDE. REFER TO THE SPECIFICATIONS AND CQA PLAN.

7. ALL LEACHATE PIPES ON THE FLOOR SHALL BE PERFORATED. CLEANOUT PIPES SHALL BE

SOLID.

8. INTERSECTING PIPES SHALL BE JOINED TO APPROPRIATELY SIZED FITTINGS BY BUTT FUSION

WELDS, UNLESS OTHERWISE NOTED.

9. PIPES NOT SHOWN IN VALLEYS SHOULD BE LAID STRAIGHT BETWEEN CONTROL POINTS AT

INDICATED SLOPES. ALL CLEANOUTS SHALL RUN PERPENDICULAR TO SLOPE.
