Coal Canyon Falsework submittal

Hi Craig, Vaskin tells me you might be able to help me out.

I have some questions regarding the Coal Canyon Falsework Submittal...
Thanks for your help!

How long will abutments be cured before attaching falsework?

Need letter of certification saying all components of manufactured
assemblies are used in conformance with the manufacturer's recommendations
(51-1.06B)

I am assuming the falsework will be adjusted to final grade using the nuts
on the deck support brackets, please confirm.

Need a superstructure placing diagram showing proposed concrete placing
sequence and direction of pour, the location of construction joints.

Dimensionwise, it looks complete to me. How much do you intend to notch at
the ends of the stringer attached to the brackets?

During construction, do you intend to to do anything over live traffic? If
so, what? You probably need a toe board on the handrail.

Will you use a bidwell to finish the deck? What pieces will they use?

Have you submitted the PC/PS Girder placement plan, with details on bracing
and how they intend to protect the girder.

Question

How much do they intend to reduce the stringers to fit under the girder?

Completed Vaskin's filing, Started work on Coal Canyon Falsework, Met with Karim Varshochi, Ben Nanjappa re record review for 55 Widening through Costa Mesa.

more questions

Is the lumber S4S or actual dimensions? should they have a toe board? They need to wait 15 days between widening pour and closure pour.

Dimensionwise, it looks complete to me. In terms of construction, do they intend to install the falsework, work on deck forming, or place concrete over live traffic? Will they use a bidwell to finish the deck? What pieces will they use? Have they submitted the PC/PS Girder placement plan, with details on bracing and how they intend to protect the girder.
