About this file
This is a bid drawing set for the Perdido Class I Landfill 2026 Northeast Pond Improvements project prepared by HDR Engineering, Inc. for Escambia County, Florida, issued for bid on February 27, 2026. The project encompasses comprehensive stormwater management improvements to the northeast pond at the Perdido Class I Landfill facility located at 13009 Beulah Road in Cantonment, Florida, and includes site grading, underdrain system installation, erosion and sediment control measures, and landscaping. Key quantities include approximately 3,042 cubic yards of cut material and 142 cubic yards of fill; 1,141 linear feet of 4-inch HDPE perforated collection pipe; 767 linear feet of 4-inch HDPE solid wall riser cleanout pipe; 307 linear feet of 12-inch HDPE perforated header pipe; and 65 linear feet of 12-inch HDPE solid wall discharge pipe. The project requires a mandatory pre-bid meeting scheduled for March 16, 2026 at 12:30 p.m., with a question deadline of March 25, 2026 at 10:00 a.m. and bid submissions due April 6, 2026 at 1:00 p.m. Work must be substantially completed within 90 consecutive calendar days from Notice to Proceed, with an additional 30 days allowed for final completion, totaling 120 calendar days maximum.
Contractors must provide lump sum pricing for nine line items and submit a bid bond, cashier's check, or certified check equal to 5% of the total bid price. The contractor shall obtain performance and payment bonds covering up to 100% of the award value and maintain comprehensive insurance coverage including workers' compensation with statutory limits, general liability of $1,000,000 per occurrence and $2,000,000 annual aggregate, business auto liability of $1,000,000 per accident, and contractor's pollution liability of $1,000,000 per occurrence and $2,000,000 annual aggregate. All materials must comply with strict specifications including AASHTO gravel gradations, HDPE piping conforming to ASTM F 714, and infiltration sand classified as SW or SP with minimum permeability of 2×10⁻³ cm/sec. Prequalification testing results from an approved third-party laboratory are required before material delivery. The contractor must provide as-built survey documentation by a Florida-registered professional land surveyor and comply with OSHA requirements, E-Verify verification, and various compliance certifications. Liquidated damages are assessed at $1,685.00 per calendar day for work extending beyond the completion deadline, and a one-year warranty on all labor and materials is required following project completion.

NOTES:
1. THE DAM SHOULD NOT BE HIGHER THAN THE CHANNEL BANKS. THE CENTER OF THE ROCK DAM SHOULD BE AT LEAST SIX INCHES LOWER THAN THE OUTER EDGES OF THE DAM AT THE CHANNEL
BANKS.
2. SIDES SLOPES SHALL BE 2:1 OR FLATTER.
3. A GEOTEXTILE SHOULD BE USED AS A SEPARATOR BETWEEN THE GRADED STONE AND THE SOIL
BASE AND ABUTMENTS. THE GEOTEXTILE SHOULD BE PLACED IMMEDIATELY ADJACENT TO THE
SUBGRADE WITHOUT ANY VOIDS AND EXTEND FIVE FEET BEYOND THE DOWNSTREAM TOE OF THE
DAM TO PREVENT SCOUR.
4. MECHANICAL OR HAND PLACEMENT WILL BE REQUIRED TO INSURE THAT THE ROCK DAM EXTENDS
COMPLETELY ACROSS THE CHANNEL AND SECURELY TIES INTO BOTH CHANNEL BANKS. THE
CENTER OF THE DAM MUST BE NO LESS THAN SIX INCHES LOWER THAN THE LOWEST SIDE, TO
SERVE AS A TYPE OF WEIR. GABIONS CAN BE INSTALLED TO SERVE AS ROCK FILTER DAMS, BUT
SHOULD FOLLOW RECOMMENDED SIZING AND INSTALLATION.
5. PERIODIC INSPECTION AND REQUIRED MAINTENANCE MUST BE PROVIDED. SEDIMENT SHALL BE
REMOVED WHEN IT REACHES A DEPTH OF ONE-HALF OF THE ORIGINAL HEIGHT OF THE DAM.
6. ROCK DAMS SHOULD BE REMOVED ONCE DISTURBED AREAS HAVE BEEN STABILIZED.

C. THE EXISTING INFILTRATION LAYER, GRAVEL AND PIPING SHALL BE REMOVED AND DISPOSED AT THE ACTIVE CLASS I LANDFILL. THE PRINCIPAL OUTLET STRUCTURE AND EMERGENCY SPILLWAY SHALL REMAIN UNDISTURBED. THE SIDE SLOPE OF THE POND SHALL BE GRADED AND COMPACTED SMOOTH TO MEET THE GRADES SHOWN IN THE DRAWINGS. THE TOPSOIL WITHIN THE SIDESLOPES SHALL BE SCRAPED (6-INCH MINIMUM) AND STOCKPILED FOR REUSE.
THE RECOVERED TOPSOIL SHALL NOT BE CONTAMINATED WITH VEGETATION DEBRIS. IF ADDITIONAL STRUCTURAL FILL MATERIAL IS NEEDED, IT CAN BE OBTAINED FROM THE OWNER'S SOIL STOCKPILE LOCATED NORTH OF THE ADMINISTRATION BUILDING.
D. AGGREGATE SHALL CONSIST OF HARD, STRONG, DURABLE PARTICLES UNLESS OTHERWISE SPECIFIED THAT ARE FREE OF ANY METAL, ROOTS, CONCRETE, DEBRIS, ORGANICS, AND OTHER DELETERIOUS MATERIALS AND COATINGS.
E. OFFSITE GRAVEL MATERIAL SHALL MEET AASHTO NO. 57 AND AASHTO #8 GRADATION AT LOCATIONS SHOWN IN THE DRAWINGS. THE RIP-RAP FOR CHECK DAMS AND OUTLET PROTECTION STRUCTURES SHALL MEET THE DIMENSIONS INDICATED ON THE DRAWINGS.
F. INFILTRATION LAYER SAND SHALL BE OBTAINED FROM OFF-SITE SOURCES APPROVED BY THE ENGINEER AND SHALL BE CLEAN, EXCAVATED, NATURAL SAND, FREE FROM ROOTS, SHARP OBJECTS, OR ORGANIC MATERIAL, WITH A MAXIMUM SIZE OF 1/4 INCH AND 5% MAXIMUM BY WEIGHT PASSING THE NO.
200 SIEVE. THE SAND SHALL BE CLASSIFIED AS SW OR SP BY THE UNIFIED SOIL CLASSIFICATION SYSTEM. THE INFILTRATION LAYER SHALL HAVE A LABORATORY PERMEABILITY NOT LESS THAN 2 X 10-3 CM/SEC AT 90% RELATIVE COMPACTION (ASTM D 698).
G. THE CONTRACTOR SHALL PROVIDE PREQUALIFICATION TEST RESULTS FROM A THIRD-PARTY LABORATORY APPROVED BY THE ENGINEER OF THE INFILTRATION LAYER FOR THE PARAMETERS HEREIN SPECIFIED. THE TESTS SHALL BE PERFORMED AT A MINIMUM FREQUENCY OF ONE PER BORROW
SOURCE AND/OR CHANGE IN MATERIAL.
H. ENGINEER RETAINS THE RIGHT TO PERFORM ADDITIONAL TESTING OF INFILTRATION SAND IF DEEMED NECESSARY DURING CONSTRUCTION TO CONFIRM
THAT REQUIRED MINIMUM PHYSICAL PARAMETERS ARE MET.
I. ANY MATERIAL DELIVERED TO SITE THAT ARE NOT MEETING MINIMUM SPECIFICATIONS SHALL BE REJECTED AT NO COST TO THE OWNER.
J. HDPE PIPING AND FITTINGS SHALL BE PROVIDED IN THE SIZES AND SHALL HAVE A STANDARD DIMENSION RATIO (SDR) AS INDICATED ON THE DRAWINGS.
DIMENSIONS AND WORKMANSHIP SHALL CONFORM TO THE REQUIREMENTS OF ASTM F 714.
K. PERFORATIONS SHALL BE DRILLED INTO THE PIPE AT THE PIPE EXTRUSION PLANT OR FABRICATION SHOP. ANY BURRS REMAINING AFTER DRILLING SHALL
BE REMOVED. PERFORATIONS SHALL BE DRILLED AND DEBURRED PRIOR TO PIPE DELIVERY TO THE JOB SITE. JOB SITE PERFORATION OR PERFORATION
BY THE CONTRACTOR SHALL NOT BE PERMITTED.
L. THE SEPARATION GEOTEXTILE PHYSICAL PROPERTIES SHALL EQUAL OR EXCEED THE MINIMUM AVERAGE ROLL VALUES LISTED IN THE TABLE BELOW.
VALUES SHOWN ARE FOR THE WEAKER PRINCIPAL DIRECTION. ACCEPTANCE OF GEOTEXTILE SHALL BE IN ACCORDANCE WITH ASTM D4759.
M. OVERLAPPING GEOTEXTILE SHALL BE THERMALLY BONDED.
N. INSTALL SEPARATION GEOTEXTILE IN ACCORDANCE WITH MANUFACTURER'S WRITTEN RECOMMENDATIONS.
O. GEOTEXTILE LEFT UNCOVERED FOR MORE THAN 14 DAYS SHALL BE REMOVED AND REPLACED AT THE CONTRACTOR'S EXPENSE P. INTERIOR SLOPES OF THE POND SHALL BE SODDED. A MINIMUM 6-INCH LAYER OF TOPSOIL SHALL BE INSTALLED BEFORE INSTALLATION OF SOD. SOD
SHALL BE RECOGNIZED BAHIA GRASS ROLLS CONFORMING TO FDOT STANDARD SPECIFICATION'S SECTION 981-5 AND SHALL BE WELL MATTED WITH ROOTS AND SHALL BE OF FIRM TOUGH TEXTURE HAVING A COMPACT TOP GROWTH AND HEAVY ROOT DEVELOPMENT. IT SHALL NOT CONTAIN WEEDS OR ANY OTHER OBJECTIONABLE VEGETATION. OTHER SODDING SPECIES MAY BE UTILIZED PURSUANT TO OWNER APPROVAL.
Q. WATER FOR SODDING SHALL CONFORM TO SECTION 983 OF THE FDOT STANDARD SPECIFICATIONS. IN ADDITION, WATERING IS REQUIRED FOR SOD
INSTALLED UNTIL VEGETATION IS ESTABLISHED.
R. CONTRACTOR SHALL PROVIDE AS-BUILT SURVEY SIGNED AND SEALED BY A PROFESSIONAL LAND SURVEYOR REGISTERED IN THE STATE OF FLORIDA. THE SURVEY SHALL INCLUDE TOPOGRAPHIC SURVEY OF THE POND, POND BOTTOM ELEVATIONS, TOP OF INFILTRATION LAYER ELEVATIONS AT 25 FT GRID, TOP
OF PIPE LOCATIONS AND ELEVATIONS AT 25 FT INTERVAL.
