Q-1) Complete Ramp Closure Chart J1 shows a window of 10 hours. Plan page X-1 shows the placement of HMA (type A) with the thickness of .25' to be placed under the Jointed Plain Concrete with a thickness of 1.0'. To perform the roadway excavation, grading, placement of the HMA and then the Concrete in 10 hours is unfeasible. The HMA needs time to cool prior to placing the concrete. If the concrete is placed when the ac is too hot it will set the concrete off too fast and possibly crack.
Can Caltrans extend the closure hours like they have done on many other projects? Many projects have a 12am Sunday morning to 5AM Monday morning giving the contractor 29 hours and not inconveniencing the public drastically.
Q-2) Also, with an engineer's estimate of $266,000.00 Caltrans needs to consider the following-
Making the AC HMA (type A) requires a lot of QC and testing which adds a lot of cost to the project for such a small amount of AC and a minor B contract. Can Caltrans change the item to Minor Asphalt Concrete?
A-1) Attention is directed to Addendum No 1.
A-2) Please place your bid in accordance with the current contract documents.
