Inquiry #4: Re: Wet Night striping item #84. First there is not spec's for wet night stating the 90 mil or 100 mil thickness , beads etc. But the main problem is all wet night in the state have always had separate line items for 6" solid , 6" broken, 8". Not lumped together like paint or sprayable because payment through measurement will become impossible later and break all the rules of the standard plans and spec's. Please try to fix this problem.

Inquiry #6: Can Plastic Pipe be used for the 8" underdrain outlets and risers? Or, will Perforated Plastic Pipe actually be allowed for the 8" Alternate Pipe Underdrain?

Standard Specification Section 68-2.02A, say "For alternative pipe underdrain, do not mix types of pipe in the same installation."
In addition, Standard Specification Section 68-2.02E say "Underdrain outlets and risers must be fabricated from the same material as the underdrain pipe or from corrugated metal pipe."

Bid item 42, 8" Corrugated Steel Pipe, is the bid item and quantity for payment of the underdrain risers and outlets.

Plan Sheet 65 list Perforated Plastic Pipe as an allowable material for underdrains. However, Bid Item 42 only allows for one type of material forcing the use of Perforated Steel Pipe for the underdrains.
