Amendment 1 - Questions and Answers and Site Visit Reminder 140R4024R0026 SJC Azotea Portal and Drop Structures

Question 1: Please clarify what concrete mix is required for the structures? There is a 5,000 psi Portland cement and 10,000 psi Silica Fume stated in the specs. It states on page 95 pg of the word document, “The contractor shall construct the drop structures walls using 5,000 psi portland cement for the drop walls and using 10,000 psi silica fume concrete for the invert foundations and drop structures baffles.“ I can’t find a concrete design for the silica fume concrete. The only mix design is for 03 30 00A for a 5,500 psi concrete and doesn’t call out the amount of Silica fume. Also, on the plans and on the bid schedule it states 5,500 psi for all of the concrete on one line item for each structure. There is also mention of “Concrete repairs of Azotea Tunnel invert from station 1418+49.60 to 1423+00,” using the silica fume mix. The plans do not show any repair details or the stationing and there is no line item for repairs.

Answer 1: The Azotea concrete requirement is 5,500 psi structural concrete as shown in the drawings. See attached updated specifications

Question 2: Bilco said that they don’t make a 42”x42” HLC door, but they do carry a 3’6”x3’0” double leaf unit. Would this work??

Answer 2: Per this size chart from Bilco they do make a 42"x42" in H20 loading. If this have discontinued this size, then 42"x36" would be acceptable and they should note this in their proposal. See attached Bilco Floor Door Size Chart.
