CLARIFICATIONS / CORRECTIONSMESTIONS AND RESPONSES <br /> The following questions (with responses ) were received after the Mandatory Pre- Bid Meeting on <br /> November 7th, 2012 : <br /> QUESTION NO. 1 <br /> There is no existing grade center line on the profile view of the ditch at the 37th Street Bridge . This is <br /> necessary for channel excavation quantities . <br /> ANSWER NO. 1 <br /> The Bridge Plans do not show the center line grade of the canal . We are not anticipating any major <br /> excavation of the canal to place the rip-rap . Please refer to the Roadway Plans cross-sections sheets <br /> for the existing canal sections. <br /> QUESTION NO. 2 <br /> Is there anyway you can break out channel excavation from rip- rap, and or provide quantities for <br /> channel excavation . <br /> ANSWER NO. 2 <br /> It is our understanding that the above question is also referring to the Bridge Plans and specifically <br /> Pay Item 530-3-3 "( Rock Rubble) (Canal Excavation as required shall be included in the cost of the rock <br /> rubble )" . The canal excavation in this case will be an incidental item to placing Rip- Rap upstream and <br /> downstream of the bridge. Please refer to cross-sections within the Roadway Plans for the Lateral A <br /> canal and sub -lateral canal elevations. <br /> QUESTION NO. 3 <br /> There is a standard plan view for 33 `d, 37th, 45th, and 49th that gives a 96' x 24' runs of rip rap lined <br /> ditches . The section views of the rip rap are standard on all of the bridges. That being said, there are <br /> huge changes in rip- rap quantities between the bridges ( i . e. 33`d Bridge 750 TN , 37th Bridge 1250 TN ) . <br /> Could there be an error in the quantities ? <br /> ANSWER NO. 3 <br /> It does not appear that there is an error in the quantities for Rip- Rap Rubble. The quantities for Rip- <br /> Rap for the new bridges designed by Bridge Design are as follows : <br /> Sheet B14; 33`d Street Bridge 11383 TN <br /> Sheet 1324; 37th Street Bridge 11268 TN <br /> Sheet B34; 45th Street Bridge 11232 TN <br /> Sheet 644; 49th Street Bridge 11320 TN <br /> Page 2 of 6 <br /> F:\Public Works\ENGINEERING DIVISION PROJECTS\0545-66Th Ave SR60 to 57th St (Arcadis)\Admim\Bid Documents\Addendum # I \Addendum No. 1 <br /> 11 -9- 12.doc <br />
