Q2. Per contract specifications section 31 37 00-2.1A(4) it states “Riprap color shall match existing materials as approved by the CO. Provide sample of rock to CO for approval prior to installing or shipping of material.” Would NPS please provide a name and location of a local source where rip rap has been approved for past projects?
A2. Past projects at ROMO have sourced rip rap material from Martin Marietta quarry (previously Albert Frei and Sons) in Walstrum or Henderson. HOWEVER, this does not mean the Government is directing any business from either of these contractors. Color to be predominately grey with some white and minimal rustic brown and brown.

A3. Engineered Rip Rap is purposely a mix of rock sizes with specific instructions for placement.
Q4. Is there as-built drawings for Big Thompson River Bridge and Aspenglen Campground Bridge? They would help provide useful information on the joint repairs. If so would you please provide?
