GENERAL NOTES:

1. SCOPE OF WORK - THIS PROJECT WILL CONSIST OF THE CONTRACTOR PROVIDING ALL LABOR, EQUIPMENT AND MATERIALS REQUIRED TO PROPERLY CONSTRUCT AND INSTALL MULTIPLE REPLACEMENT FLOATING BOAT DOCKS AT VARIOUS LOCATIONS WITHIN THE WASHINGTON COUNTY STATE RECREATION AREA (SRA). A SUMMARY OF

THE PROPOSED PRIMARY WORK ITEMS INCLUDES BUT IS NOT LIMITED TO:

1.1. REMOVAL OF EXISTING FLOATING BOAT DOCKS, AND ALL ASSOCIATED ITEMS INCLUDING GANGWAY, ABUTMENT, AND SPUD POLES.

1.2. INSTALLATION OF NEW FLOATING BOAT DOCKS, GANGWAYS, SPUD POLES, AND CONCRETE ABUTMENTS.

1.3. ALL NEW DOCKS AND GANGWAYS ARE TO BE GALVANIZED STEEL FRAME CONSTRUCTION WITH ENCAPSULATED FLOATATION AND COMPOSITE DECKING.

1.4. ALL DOCKS WILL INCLUDE A NEW CONCRETE ABUTMENT/APPROACH PAD, RIPRAP PROTECTION, AND STEEL SPUD POLE ANCHORAGE.

1.5. DOCK LOCATIONS 1, 2 AND 3 ARE TO BE INCLUDED IN THE BASE BID.

1.6. DOCK LOCATIONS 4, 5, 6 AND 7 ARE TO BE INCLUDED AS INDIVIDUAL ADDITIVE ALTERNATE BIDS.

2. PROJECT AREA - THE OVERALL PROJECT CONSISTS OF MULTIPLE INDIVIDUAL SITES SPREAD ACROSS VARIOUS LOCATIONS OF THE WASHINGTON COUNTY SRA, WHICH WILL CONTINUE TO BE OPEN TO AND USED BY THE GENERAL PUBLIC THROUGHOUT CONSTRUCTION. ALL WORK SHALL BE COORDINATED WITH THE SITE SUPERINTENDENT AND CONDUCTED IN AN ORDERLY AND EFFECTIVE MANNER TO MINIMIZE IMPACTS TO THE OWNER AND GENERAL PUBLIC.

3. ORDER OF OPERATIONS - CONCURRENT WORK AT MULTIPLE SITES WILL BE LIMITED TO THOSE ONLY WITHIN CLOSE PROXIMITY OF EACH OTHER AND WITHIN THE CAPABILITIES OF THE CONTRACTOR TO MAKE CONTINUAL PROGRESS AT EACH LOCATION. PARTIAL ACCEPTANCE MAY BE REQUESTED OF SUBSTANTIALLY COMPLETED INDIVIDUAL SITES IN ORDER TO MAINTAIN A REASONABLE LEVEL OF SERVICE TO THE GENERAL PUBLIC UNTIL ALL CONSTRUCTION IS COMPLETED.

4. SAFETY - CONTRACTOR SHALL PROVIDE APPROPRIATE VEHICULAR AND PEDESTRIAN TRAFFIC CONTROL VIA TRAFFIC CONES, BARRICADES, SIGNAGE, CAUTION TAPE, AND/OR PHASING AS NECESSARY AND AS REQUESTED BY THE SITE SUPERINTENDENT TO MAINTAIN PUBLIC SAFETY DURING CONSTRUCTION. ALL PRIMARY PARK AND CAMPGROUND ROADS SHALL REMAIN OPEN UNLESS CLOSURE IS AUTHORIZED BY THE SITE SUPERINTENDENT. ALL ACTIVE WORK AREAS SHALL BE CLOSED OFF TO PUBLIC ACCESS, AND ANY OPEN EXCAVATIONS SHALL BE FENCED OFF OVERNIGHT. THE CONTRACTOR IS RESPONSIBLE FOR SECURING THEIR EQUIPMENT AND

MATERIALS.

5. PRECONSTRUCTION MEETING - PRIOR TO INITIATING ANY CONSTRUCTION THE CONTRACTOR SHALL COORDINATE A PRECONSTRUCTION MEETING WITH THE IDNR PROJECT MANAGER, SITE SUPERINTENDENT, AND OTHER STAKEHOLDERS AS APPROPRIATE. A PROPOSED CONSTRUCTION SCHEDULE AND DRAFT CONTRACTOR'S SCHEDULE OF

VALUES (CSV) SHALL BE SUBMITTED FOR IDNR REVIEW.

6. SITE LAYOUT

6.1. SOME ITEMS, DIMENSIONS, AND QUANTITIES DEPICTED ON THE PROPOSED SITE PLAN LAYOUTS MAY BE SHOWN SCHEMATICALLY OR PROVIDED FOR THE

CONTRACTOR'S GENERAL REFERENCE . THE CONTRACTOR IS RESPONSIBLE FOR VERIFYING ALL SITE CONDITIONS AND QUANTITIES PRIOR TO BIDDING, AND ULTIMATELY ENSURING EACH COMPLETED SITE HAS POSITIVE SITE DRAINAGE, CLEANLY TIES IN TO EXISTING FEATURES, IS COORDINATED WITH EXISTING UTILITIES, IS IN COMPLIANCE WITH ADA GRADE REQUIREMENTS, AND MEETS THE OVERALL DESIGN INTENT. MINOR FIELD ADJUSTMENTS MAY BE REQUIRED TO ACHIEVE THESE CONDITIONS OR TO ACCOMMODATE VARIATIONS ACROSS DIFFERENT MANUFACTURERS. NO ADDITIONAL COMPENSATION WILL BE ALLOWED FOR SUCH MODIFICATIONS.

6.2. PRIOR TO CONSTRUCTION AND INSTALLATION, FINAL LOCATIONS AND ELEVATIONS OF DOCKS AND ABUTMENTS SHALL BE STAKED BY THE CONTRACTOR AND APPROVED

BY THE DNR REGIONAL ENGINEER.

7. PRIOR TO COMMENCING SITEWORK, CONTRACTOR SHALL IDENTIFY, INVESTIGATE, AND LOCATE ANY EXISTING UTILITIES THAT MAY BE IN CONFLICT WITH THE PROPOSED WORK. ANY POTENTIAL CONFLICTS SHALL BE BROUGHT TO THE ATTENTION OF THE IDNR PROJECT MANAGER TO DETERMINE IF FURTHER ACTION IS NEEDED. DAMAGE TO

ANY EXISTING UTILITIES SHALL BE REPAIRED AT THE CONTRACTOR'S EXPENSE.

8. THE CONTRACTOR SHALL TAKE CARE NOT TO CAUSE DAMAGE TO ANY TURF AREAS, TREES, PAVEMENTS, UTILITIES, OR OTHER FEATURES ADJACENT TO THE WORK AREA LIMITS SHOWN. ANY DAMAGE SHALL BE REPAIRED AT THEIR EXPENSE WITH LIKE OR NEWER MATERIALS. ALL DISTURBED TURF AREAS SHALL BE GRADED, SEEDED, FERTILIZED AND MULCHED.

9. ALL EXCESS EXCAVATION AND REMOVED MATERIALS, EXCEPT AS NOTED, SHALL BE HAULED OFFSITE AND DISPOSED OF IN A LEGAL MANNER.
