About this file

Written by GovTribe AI · Dec 28, 2023

This solicitation is for a construction contract to perform salmon habitat enhancement work at Muir Woods National Monument in Marin County, California. The work includes installing three separate water diversion systems with channel work zones extending 400 to 450 linear feet each, totaling 3,100 linear feet of channel. Other efforts involve removing rock slope protection from banks, grading banks and the channel bed, and placing large woody debris structures. The contract also requires demolishing 460 linear feet of asphalt trail and a sewer line segment. The contractor must provide all labor, equipment, testing and supplies to complete the specified work following resource protection restrictions. The work must finish before late fall rains begin the salmon spawning season. The solicitation estimates the project value between $1,000,000 to $5,000,000. Interested offerors should access the full solicitation on SAM.gov and attend an optional site visit on March 10, 2023. Questions are due to the National Park Service contracting officer.

TABLE 2. RSP VOLUMESTABLE 1. RSP DIMENSIONS

NOTES ON ASPHALT AND BASE ROCK VOLUME ESTIMATES:

· AREA 2: VOLUME OF ASPHALT AND BASE ROCK WAS ESTIMATED BASED ON STRATIGRAPHY

OBSERVED IN PITS THAT WERE DUG ADJACENT TO THE TRAIL. EXTENT OF BASE ROCK MAY BE WIDER

THAN ASPHALT. ACTUAL DIMENSIONS ALONG THE LENGTH OF THE TRAIL MAY VARY.

TABLE 3. ASPHALT AND TRAIL BASE ROCK VOLUMES

NOTE: NA = NOT APPLICABLE

NOTES ON METHODS FOR RSP VOLUME ESTIMATES (SEE ALSO: RSP DIMENSIONS TABLE, THIS SHEET):

· RSP L1 (SECTION TO BE REMOVED): LAYER 1 ROCK WAS DIVIDED INTO TWO SECTIONS: 1) A DOWNSTREAM ~65 FT LONG SECTION OF EMBEDDED ~1 FT DIA ROCK AND 2) AN UPSTREAM ~45 FT LONG SECTION ~2 FT DIA ROCK. A SECOND LAYER WAS OBSERVED BY PROBING.

THE TOE OF THE UPSTREAM SECTION (TO BE REMOVED) WAS EXPOSED; THEREFORE, NONE OF THE RSP IN L1 IS ASSUMED TO BE EMBEDDED BELOW THE CHANNEL BED.

· RSP R1 (SECTION TO BE REMOVED): LAYER 1 ROCK IS A SINGLE ~70 FT LONG SECTION CONSISTING OF WELL-EMBEDDED ~2 FT DIA ROCK. THE TOE OF THE RSP WAS COVERED IN A GRAVEL BAR DURING OBSERVATION, WHICH WAS NOT EXCAVATED OR EXPLORED TO

COFIRM DEPTH OF RSP. TWO LOCATIONS WERE PROBED BEHIND LAYER 1 AND NO SECOND LAYER WAS OBSERVED.

· R2 (SECTION TO BE REMOVED): LAYER 1 ROCK IS A SINGLE ~70 FT LONG SECTION CONSISTING OF ~2 FT DIA ROCK. A SECOND LAYER WAS OBSERVED BY PROBING. THE TOE OF THE R2 SECTION (TO BE REMOVED) WAS EXPOSED; THEREFORE, NONE OF THE RSP IN R2 IS

ASSUMED TO BE EMBEDDED BELOW THE CHANNEL.

· RSP R2B: LAYER 1 ROCK IS ESTIMATED TO BE A SINGLE ~40 FT LONG SECTION CONSISTING OF A SINGLE LAYER OF ~1.5 FT DIA ROCK, ORIGINATING FROM THE NORTH END OF BRIDGE 1.5 AND EXTENDING INTO THE UPSTREAM CHANNEL BANK.

· RSP L2: LAYER 1 ROCK WAS DIVIDED INTO FOUR SECTIONS: 1) AN UPSTREAM ~40 FT LONG SECTION OF WELL-EMBEDDED ~1 FT DIA ROCK, 2) A ~55 FT LONG SECTION OF ~2 FT DIA ROCK, INCLUDING A ~10 FT LENGTH OF LAUNCHED BOULDERS, 3) A FAILED ~15 FT LONG

SECTION OF ~1 FT DIA (REMAINING) ROCK THAT LAUNCHED BOULDERS INTO THE CHANNEL, AND 4) A DOWNSTREAM ~20 FT LONG SECTION OF EMBEDDED ~2 FT DIA ROCK. A SECOND LAYER WAS OBSERVED BY PROBING.

· RSP R3 (SECTION TO BE REMOVED): LAYER 1 ROCK WAS DIVIDED INTO THREE SECTIONS: 1) AN UPSTREAM ~70 FT LONG SECTION OF ~2 FT DIA ROCK, WITH A ~10 FT LONG FAILURE, 2) A ~40 FT LONG SECTION OF ~1.5 FT DIA ROCK, WITH LAUNCHED ROCK ALONG THE TOE

OF THE BANK 3) ~70 FT LONG SECTION OF ~2 FT DIA ROCK, WITH BOULDERS LAUNCHED IN THE CHANNEL. A SECOND LAYER WAS OBSERVED BY PROBING.

· RSP R6: LAYER 1 ROCK WAS DIVIDED INTO THREE SECTIONS: 1) AN UPSTREAM ~60 FT LONG SECTION OF WELL-EMBEDDED ~2 FT DIA ROCK, 2) A FAILED 20 FT LONG SECTION AND 3) A DOWNSTREAM ~50 FT LONG SECTION OF LOOSE ~2.5 FT DIA ROCK. LAYER 2 VOLUME

ASSUMES A SOLID 0.5 FT LAYER BEHIND THE DOWNSTREAM 75 FT OF LAYER 1. LAYER 2 ASSUMPTION IS BASED ON OBSERVATIONS OF 0.5 FT ROCK EMBEDDED IN THE BANK AT FAILURE LOCATIONS, THOUGH A SOLID LAYER WAS NOT OBSERVED AND 0.5 FT ROCK COULD BE CHINK MATERIAL, NOT A SECOND LAYER. PROBING 6 LOCATIONS (TO 1.5' DEPTH) BEHIND THE ROCK WAS NON-CONCLUSIVE. SUBSURFACE ROCK ESTIMATE ASSUMES SUBSURFACE ROCK ALONG THE DOWNSTREAM ~50 FT SECTION OF RSP ONLY (WHERE EMBEDDED

ROCK WAS OBSERVED IN CHANNEL BED).

GENERAL NOTES ON RSP VOLUMES:

· VOLUMES ARE PROVIDED FOR INFORMATIONAL PURPOSES ONLY; CONTRACTOR IS RESPONSIBLE FOR VERIFYING ALL VOLUMES.

· ESTIMATED VOLUMES REPRESENT CURRENT RSP PLACEMENT ON THE BANKS, WHICH IS TIGHTLY INTERLOCKED WITH MINIMAL VOID SPACE. RSP VOLUME ESTIMATES WERE COMPUTED BY MULTIPLYING THE LENGTH, THICKNESS, AND SLOPE LENGTH (SEE RSP

DIMENSIONS TABLE, THIS SHEET).

· RSP SECTION LENGTH AND SLOPE LENGTH WERE SURVEYED AND SECTION THICKNESS WAS ESTIMATED BY PROBING 1.5 FT BELOW GROUND SURFACE ALONG THE TOP OF BANK BEHIND RSP SECTIONS.

· IT IS NOT KNOWN HOW FAR RSP SECTIONS EXTEND BELOW THE CHANNEL BED OR BANK. EXPLORATORY EXCAVATION SHALL BE CONDUCTED AT THE TOES OF ALL RSP SEGMENTS TO IDENTIFY POSSIBLE PRESENCE OF BURIED RSP. ALL SUBSURFACE ROCK SHALL BE

REMOVED AS PART OF THIS WORK, UNLESS THE TOP OF THE SUBSURFACE ROCK IS BELOW THE ELEVATIONS SPECIFIED IN THESE DRAWINGS. HISTORICAL PHOTOS DO NOT SHOW TRENCHING THAT WOULD INDICATE SUBSURFACE ROCK OR THAT RSP WAS CONSTRUCTED

WITH MORE LAYERS ON THE BANK THAN CURRENTLY VISIBLE.

1. REMOVAL OF RSP INCLUDES REMOVAL OF ALL ROCK ASSOCIATED WITH RSP

SECTION, INCLUDING ROCK BURIED IN THE CHANNEL BED AND/OR

ADDITIONAL LAYERS OF ROCK IN THE BANK.

2. CONTRACTOR SHALL USE METHODS TO REMOVE RSP FROM THE BANK T0

MINIMIZE BANK DISTURBANCE, CUTTING OF TREE ROOTS, SOIL LOSS, AND

VEGETATION DISTURBANCE. HERBACEOUS VEGETATION THAT WOULD

INTERFERE WITH RSP REMOVAL MAY BE REMOVED WITH CO APPROVAL, AN

NPS BIOMONITOR PRESENT AND USING METHODS THAT AVOID GROUND

DISTURBANCE.

3. ALL BANKS SHALL BE INSPECTED BY COR AFTER RSP LAYER 1 REMOVAL AND

AGAIN AFTER EACH SUBSEQUENT LAYER OF RSP IS REMOVED. ROCK

REMOVAL METHODS OR GRADING OF BANKS MAY BE MODIFIED TO AVOID

IMPACTS TO TREE ROOTS.

GENERAL RSP REMOVAL NOTES

1. CUTTING WOOD FOR ACCESS SHOULD BE AVOIDED WHERE POSSIBLE.

2. IF CUTTING WOOD IS NECESSARY, CUT WOOD TO THE LARGEST MOVEABLE SIZE AND

MINIMIZE REMOVAL OF BRANCHES. CUT WOOD AT LOCATION SPECIFIED ON DRAWINGS.

3. DO NOT CLEAR ANY VEGETATION EXCEPT THE TREE OR WOOD THAT IS IDENTIFIED FOR

REMOVAL.

4. PRIOR TO MOVING WOOD, LOCATE AND CLEARLY IDENTIFY THE WOOD TO BE MOVED AND

PATH THAT WOOD SHALL BE MOVED. IDENTIFY ANY INTERMEDIATE TEMPORARY PLACEMENT

LOCATIONS AND COORDINATE INSPECTIONS PRIOR TO MOVEMENT AND PLACEMENT WOOD

WITH BIOLOGICAL MONITOR.

5. RETAIN ANY CUT BRANCHES FOR USE AS SWD BELOW PLACED WOOD AS SHOWN ON

DRAWINGS.
