Written by GovTribe AI · Dec 21, 2023

This solicitation is for improvements to three beach access locations on Grand Island in Michigan's Hiawatha National Forest. Work includes removing existing deteriorating wood stair structures and constructing new gabion shoreline stabilization, rock-filled drainage swales, and wood-framed stair structures with aluminum stairs for beach access. An aluminum stair section will be raised and lowered using a cable winch system. Disturbed soil areas will be graded and seeded. The Forest Service is the contracting agency. The response due date is not provided, and award information is absent.

PROJECT ACCESS NOTES

1. ACCESS BY FERRY / BARGE: THE ISLAND CAN BE ACCESSED BY THE USING GRAND ISLAND LANDING ON THE MAINLAND TO THE WILLIAMS LANDING ON THE

SOUTH END OF THE ISLAND. THERE IS A FERRY / BARGE SERVICE THAT IS RUN OUT OF THE GRAND ISLAND LANDING. THE CONTRACTOR MUST COORDINATE THE

DETAILS OF USING THIS FERRY / BARGE SERVICE DIRECTLY WITH THE GRAND ISLAND WATER TRANSPORTATION CONCESSIONAIRE IF PLANNING TO USE THIS

METHOD TO ACCESS TO THE ISLAND. HTTP://WWW.GRANDISLANDUP.COM

2. ACCESS BY OTHER WATERCRAFT: IT MAY ALSO BE POSSIBLE TO ACCESS THE PROJECT LOCATIONS BY OTHER WATERCRAFT. THE DETERMINATION OF THE

SUITABILITY OF DIRECT WATER ACCESS TO THE PROJECT LOCATIONS IS THE RESPONSIBILITY OF THE CONTRACTOR. THE CONTRACTOR SHALL COORDINATE

ANY PROPOSED USE OF THE FERRY/BARGE LANDINGS DIRECTLY WITH THE GRAND ISLAND WATER TRANSPORTATION CONCESSIONAIRE.

3. ISLAND ROADS: THE PROJECT LOCATIONS CAN BE ACCESSED BY USING THE ISLAND ROADS THAT ARE DESIGNATED ON THE PROJECT ACCESS MAP. THE

CONTRACTOR MUST EVALUATE THE CONDITION AND GEOMETRY OF THE EXISTING ISLAND ROADS BEFORE ATTEMPTING TO DRIVE OR HAUL EQUIPMENT AND

MATERIALS ON THE ROADS. IF IMPROVEMENTS TO THE ISLAND ROADS ARE REQUIRED TO ALLOW ACCESS BY LARGE VEHICLES, EQUIPMENT, OR MATERIALS

(SUCH AS ROAD WIDENING OR VEG CLEARING), SUCH IMPROVEMENTS MUST BE APPROVED IN ADVANCE BY THE COR. SUBMIT REQUESTS FOR SUCH

IMPROVEMENTS WITH SUFFICIENT DETAIL TO ALLOW EVALUATION BY FS STAFF. ALLOW AT LEAST 7 DAYS FOR EVALUATION AND APPROVAL OR REJECTION OF

THE REQUESTS BY THE COR. SUCH IMPROVEMENTS WILL BE CONSIDERED INCIDENTAL TO OTHER WORK ON THIS CONTRACT, AND WILL NOT BE PAID FOR

SEPARATELY. (IT IS SUGGESTED THAT THE CONTRACTOR INCLUDE ANY COSTS FOR SUCH ACCESS IMPROVEMENTS IN THE MOBILIZATION WORK ITEM.)

2. DESIGN INTENT IS THAT STRUCTURE IS DISASSEMBLED STARTING FROM THE BOTTOM, WITH THE DEMO DEBRIS BROUGHT

UP THE REMAINING STRUCTURE FOR REMOVAL AND PROPER DISPOSAL. THIS METHOD IS SUGGESTED TO REDUCE THE

AMOUNT OF DISTURBANCE TO THE EXISTING GROUND AND VEGETATION TO REMAIN. REGARDLESS OF METHOD USED BY

CONTRACTOR, DISTURBANCE OF EXISTING GROUND AND VEGETATION SHALL BE KEPT TO THE MINIMUM PRACTICAL.

3. THE EXISTING STAIR STRUCTURE IS TO BE REMOVED COMPLETELY. WOOD POSTS SHALL BE CUT OFF AT CONCRETE

HEMLOCK STAIR - OVERALL SCOPE OF WORK

THE PRIMARY INTENT OF THE WORK AT THE HEMLOCK STAIR LOCATION IS TO REMOVED THE

EXISTING FAILING STAIR STRUCTURE AND PROVIDE A REPLACEMENT METHOD OF ACCESS TO

THE BEACH. IN ADDITION, THE WORK WILL INCLUDE MEASURES TO PROTECT THE NEW

ACCESS STRUCTURE AND REDUCE/PREVENT SLOPE AND SHORELINE EROSION IN THIS AREA.

WORK AT THE HEMLOCK SITE INCLUDES (BUT IS NOT LIMITED TO) THE FOLLOWING MAJOR

ACTIVITIES:

1. REMOVAL OF EXISTING STAIRS

2. LAYOUT STAKING OF ALL COMPONENTS FOR REVIEW AND APPROVAL BY COR.

3. CONSTRUCTION OF GABION SHORELINE STABILIZATON AND DRAINAGE SWALES WITH

REVENTMENT MATS

4. CONSTRUCTION OF NEW STICK-FRAMED STAIRS AND LANDING STUCTURE

5. MOUNTING OF PRE-MANUFACTURED ALUMINUM STAIRS FROM STAIR LANDING TO BEACH

6. CONSTRUCTION OF LIFT SYSTEM FOR THE ALUMINUM STAIR SECTION

7. REPAIR OF DISTURBED AND/OR FAILING SOIL BANK AREAS, INCLUDING FILL WHERE

INDICATED

8. FINAL GRADING AND PREPARATION FOR SEEDING

9. HYDRO SEEDING AND MULCHING

HEMLOCK STAIR - GENERAL NOTES

1. CONTRACTOR SHALL VERIFY ALL EXISTING DIMENSIONS AND CONDITIONS AGAINST WHAT

IS SHOWN ON THIS PLAN. IF ANY DISCREPANCIES WHICH WILL AFFECT THE WORK ARE

DISCOVERED, THE CONTRACTOR SHALL REPORT THE DISCREPANCY TO THE COR

IMMEDIATELY UPON DISCOVERY.

2. EXISTING STAIR STRUCTURE IS TO BE REMOVED COMPLETELY. WOOD POSTS SHALL BE

CUT OFF AT CONCRETE EMBEDMENT. CONCRETE THAT IS LOOSE AND EASILY

EXTRACTABLE FROM THE SOIL SHALL BE REMOVED. CONCRETE THAT IS SECURELY

EMBEDDED IN SOIL SHALL REMAIN IN ORDER TO PREVENT FURTHER DESTABILIZATION OF

THE EXISTING BANK.

3. EXISTING RETAINING WALL IS TO REMAIN AND BE INCORPORATED INTO THE NEW WORK.

PROTECT AS REQD DURING ALL PHASES, AND MAKE IMPROVEMENTS AND MODIFICATIONS
