Inquiry #1: Regarding the recessed thermoplastic striping; is it Caltrans' intention to have the recessed thermoplastic yellow centerline installed in the rumble strip? This is not normal, and there will be issues in regard to the hot thermoplastic material flowing into the actual rumble strip. There may also be huge variations in the continuity of the 4" yellow thermo striping. Yellow Recessed thermo details 21 & 22 should be widened out and one (1) 4" Stripe placed on each side of the rumble strip. As for the passing details 6 & 19; there should be no rumble strip placed on the centerline where passing is allowed.
Also; the quantity for Item #28 4" Thermoplastic Stripe (Recessed) should be 750,000 lineal feet. The item pays as 4" Thermo Stripe and thus the yellow details 19, 21, 22, 29 and white details 37B, 38A should be doubled as per the Standard Specifications.

Inquiry #8: RE: 08-SBd-38-15.0/49.5 08-0G6204 Project ID 0800000218

Subject: RFI "Species protection requirements"

Dear Sir(s)

Section 14-6.02A states "no construction shall occur between February 15 and September 15 within the SPA 2 from post mile (PM) 30.5 and (to ) post mile 37.5 where suitable breeding habitat for Southwestern Willow Flycatcher is present."

Is it the intention of Caltrans to start the paving work leaving out the above stated area to be preformed after September 15,2014 which will be the start of the cold weather in the mountains for paving.
And if so, will Caltrans agree to suspend the working days for this period of time.

Thank you for your consideration in this matter.
