Plan Sheet / Specification Reference=Item #3 TEMPORARY CONSTRUCTION ENTRANCE 

There is no construction detail sheet in the project plans. 

  • Bid it as you see using the TYPICAL ACCESS TO CONSTRUCTION AREA DETAIL including SECTION A-A as shown on Plan Sheet 95 TRAFFIC HANDLING PLAN TH-1.
Plan Sheet / Specification Reference=SPECIAL PROVISION SECTION 10-1.40, PLAN SHEET 47 (C-1), Item #31: SINGLE THRIE BEAM BARRIER 

Plan details on C-1 include unusual post size and spacing for single thrie beam barrier at K-RAIL to K-RAIL locations. Standard Plans A78F and A78G are different. Due to the multiple bridge rail connections, we request a similar construction detail for K-RAIL to BRIDGE RAILS.

  • For K-RAIL to BRIDGE RAIL connections use Standard Plan A78F or A78G for post size of 250 mm with a distance of 953 mm for the first and second post at the bridge rail side. Use CONSTRUCTION DETAIL C-1 (sheet 47 of the plans) for the post size of 250 mm with the first post at 667.5 and the second post at 953 mm. The remaining distance between the connections shall use Standard Plan A78A for a post size of 150 mm x 200 mm with post spacing at 1905 mm. All details apply accordingly. 
Plan Sheet / Specification Reference=Plan Sheet 48 (C-2), Section A-A

Section A-A calls for scuppers at 3.0 m while both the Plan and Elevation views show the scuppers at 3.76 m center to center. Please verify the intent to use the 3.76 m center to center spacing for the scuppers.

  • The correct distance is 3.76 m center to center.
Plan Sheet / Specification Reference=Section 10-1.01 ORDER OF WORK, Item 10: REMOVE CABLE BARRIER

Can cable barrier removal from Sta. 518+00 to 551+00 happen prior to temporary k-rail installation?

  • No, per Section 10-1.01 ORDER OF WORK the cable barrier must remain in place until the completion of the installation of the k-rail. 
Plan Sheet / Specification Reference=Section 10-1.38 CONCRETE BARRIER- paragraph 2 & 3 and Section 10-1.39 CONCRETE BARRIER (TYPE K)-paragraph 5 & 6

"The top and side surfaces of concrete barriers which face traffic shall be abrasive blasted to produce a generally uniform color and sandy texture with air and water bubbles in the concrete exposed.
The top and both side surfaces shall be prepared and painted in accordance with the provisions in Sections 59, "Painting," and 91, "Paint," of the Standard Specifications and these special provisions. "

Are both side surfaces and top to be prepped and painted or only the top and side toward traffic?

  • It is only necessary to blast the top and traffic side, but it is required to paint the top and both sides: traffic and non-traffic side. 
Plan Sheet / Specification Reference=Section 10-2.02 PRUNE EXISTING PLANTS and plan sheet HP-32 PRUNING CROSS SECTION
