Item 1 - Response to RFI received subsequent to the issuance of ADDENDUM #4 : <br /> 1 . SHEET U -7 REVISED LIFT STATION : PLEASE PROVIDE A COPY OF THE SFWMD WATER <br /> WITHDRAWL / DEWATERING PERMIT . ALSO PROVIDE A COPY OF THE DEWATERING <br /> PLAN SHOWING WATER DISTRIBUTION , HOLDING , AND REMOVAL . <br /> The means and methods of any required dewatering are up to the CONTRACTOR. CONTRACTOR <br /> needs to be advised he is subject to SJRWMD dewatering criteria, not SFWMD. Also, caisson <br /> installation method should dramatically change dewatering requirements. <br /> 2 . GEOTECHNICAL : THE PILE INSTALLATION IS UNCLEAR WHETHER DRIVING IS <br /> REQUIRED . ALSO , IF DRIVING IS A REQUIREMENT , DOES IT HAVE ANY IMPACT ON THE <br /> TURTLE NESTING SEASON ? <br /> Piling for the boardwalk, ADA ramp, and stairs are not required to be driven; per the DRAWINGS by <br /> Coastal Tech : "Piles shall have a minimum embedment of 8 ' feet below existing grade or to <br /> elevation 0. 0 NGVD whichever is lower. " The AM Engineering geotechnical report indicates the <br /> piles are to be driven to final bearing. Pavilion piles may be jetted to within 2 feet of the minimum <br /> tip elevation and driven the last 2 feet. 4 <br /> 3 . ITEM # 14 - EXISTING IRRIGATION WELL AND IRRIGATION SYSTEM : PLEASE PROVIDE <br /> THE CHARACTERISTICS OF THE EXISTING WELL . PLEASE PROVIDE THE EXTENT OF <br /> WORK FOR IRRIGATION SYSTEM REPLACEMENT . <br /> Existing piping and wells have been cleared and exposed. A site visit with the plans in hand will <br /> greatly clarify the "assumptions ". Yes, we are aware the existing well data is not known, however, <br /> our assumption is that it is not irrigating the sod with salt water and is therefore less than 20 feet <br /> deep. <br /> 4 . A . PLEASE CLARIFY THE LENGTH OF 16 PILES @ 10" DIAMETER FOR THE PAVILION <br /> AREAS . <br /> B . PLEASE CLARIFY THE LENGTH OF ALL 6X6 WOOD PILES FOR BOARDWALKS . <br /> C . PLEASE CLARIFY THE LENGTH OF 6X6 WOOD PILES FOR THE COVERED BENCH <br /> AREA LOCATED AT BOTH SIDES OF 8 ' WIDE BOARDWALK . <br /> A. . For the piles at the pavilion, i. e. 10 " Timber piles the minimum tip elevation should be +9. 0 ' <br /> NGVD. Section 2/S-4 shows the top of the pile at +28. 0 'NGVD and the top of slab at + 18. 0 'NGVD. In <br /> addition to the minimum tip elevation of +9. 0 the minimum embedment should be 9 feet. So, if the <br /> final grades are as indicated on the section the minimum final pile length is 19 '-0 ". Driving <br /> parameters and cut off may require a longer pile, the pile Contractor should be consulted. <br /> B. 6X6 piles for the main boardwalk shall have a minimum length of 21 . 5 ' ((+ 18 'NGVD - O. ONGVD) <br /> +3. 5 ']. Any splices shall occur at the pile cap - as approved by the ENGINEER. <br /> C. 6X6 piles for the covered bench area located a both sides of 8 ' wide boardwalk shall have a <br /> minimum length of 27' [(+18 'NGVD - O. ONGVD) +9 ']. Any splices shall occur at the pile cap - as <br /> approved by the ENGINEER. <br /> The cost to furnish and install all piling as shown shall be included in the LUMP SUM BID ITEM 2. 01 . <br /> 5 , IN SECTION 03000 , ARTICLE 2 . 1 , ITEM B , YOUR ENGINEER HAS SPECIFIED THE PILES TO <br /> BE TREATED WITH . 40PCF MCQ WITH THE PILES BEING KILN DRIED AFTER TREATMENT . <br /> IT IS MY STRONG RECOMMENDATION THAT YOU SUGGEST THE USE OF . 80 CCA <br /> PILINGS . <br /> The following wood treatments will be acceptable alternatives for the construction of the boardwalk: <br /> FAPublic Works\Cliff Suthard\Wabasso Beach Park\A Construction Bid Documents\Bid Documents as of 2-6-2008\Addendum #1 #2, #3 , #4 , & <br /> #5\Addendum #5.doc <br /> Page 2 of 3 <br />
