Question=With regard to paving and slurry items 17-20, is it Caltrans
intention to perform CONTRACT NO. 11-241184 during the Winter months?

The average daytime temperature for Lakeside, California during the Winter
is 56.7 degrees, and the average nightime temperature is 39.7 degrees.  With
this in mind, it is doubtfull that your working shift charts are applicable
(with regard to allowable paving temperatures) until sometime in the late
Spring.

The per shift Rubber Asphalt Plant and Slurry Plant fees are much to
expensive for the Contractor to play a guessing game with temperature during
the Winter and early Spring months!  With Liquidated Damages being at
$6,200.00 per day, this also lends credence to performing this project
during the warmer months.
 

• Please bid per the contract documents.

Question=With approximately 2.5 million square feet of existing AC surfacing, currently under traffic, that will be subject to Warranty coverage; how does Caltrans anticipate the Contractor to identify areas for exclusion and how will Caltrans review these areas?  Will the Contractor be required to establish traffic control?  If so, how much time per lane mile will Caltrans need for review? 

             Question, How does Caltrans anticipate the Contractor to identify areas or exclusion and how will Caltrans review these areas?

• Please refer to Section 10-1.22, "Warranty," of the Special Provisions,                                                                                                                                                                                                                               Paragraph 6:                                                                                                                                                                                                                                        The warranty shall not apply to excluded areas designated on the plans and to other identified areas where the existing surfacing prior to application of surfacing, contains defective areas as determined by the Engineer.  At least 7 days prior to beginning placement of the rubberized asphalt concrete (Type O), the Contractor shall submit to the Engineer a written list of existing defective areas, identifying the lane direction, lane number, starting and ending highway post locations and defect type.  Within 4 working days of receiving the list of existing defective areas, the Engineer will review the list and provide the Contractor written approval or revisions of the areas, as being excluded from the warranty.  Defects in the existing surfacing which may qualify areas for exclusion from the warranty include: rutting greater than 9 mm, patches of cold mixed asphalt concrete placed within the last 12 months, and 30-m lengths of lane or shoulder in which the cracking exceeds 10 percent as determined by the length of interconnecting cracks in the wheel paths divided by 60 m and expressed as a percentage.  Rutting that shall be excluded from the warranty is defined as a longitudinal depression in the wheel path that, when measured by placing a straightedge 3.6± 0.06-m long on the finished surface and perpendicular with the center line, varies more than 9 mm from the lower edge of the straightedge or a 160-m length that shows an average rut measurement, when measured from the California Profilgraph, greater than 9 mm.  Segments of the project excluded from warranty for rutting or cracking shall be warrantied for the other criteria.  Segments repaired by the Contractor shall be warrantied for all criteria.  Placement of the rubberized asphalt concrete (Type O) shall not begin until the Engineer has approved the list of existing defective areas, and repairs included in the contract have been made.  The rubberized asphalt concrete (Type O) placed over areas, shown on the plans or designated by the Engineer, to be repaired shall be warrantied.

 
Question:  Will the Contractor be required to establish traffic control?  If so, how much time per lane mile will Caltrans need for review?
