How are the guardrail posts and blocks in the raising guardrail bid item being paid for? Also there doesn’t seem to be a bid item for removing and replacing bridge rail

Additional guardrail posts and blocks required in areas where guardrail is to be raised are included within Item 61710-0000, Raising Guardrail. See Subsection 617.10 of the SCRs.

Bridge rail removal is included under Item 57501-0000 (Scoggins Creek) and Item 57501-0000 (Sain Creek). See Subsection

575.01 of the SCRs.

#1The project specification doesn’t show how the extra length posts in bid item 61701-2000 are paid for. The problem here is your bid item quantity exceeds those shown in the plans. There should be a bid item for longer posts.

The bid price for Item 61701‐2000 is for the complete system, including posts. The Bid Schedule quantity includes an “allowance.”

Bid the quantity shown in the Bid Schedule.

#2 The project spec.section 617.10 raising guardrail indicate you are to add posts to achieve 6.25’ spacing. It doesn’t tell us how the added blocks and hardware are to be paid for.

6 x #4 There is no bid item for bridge railing, it really doesn’t fall under item 57501‐000.

All bridge work is paid for under the 57501 items. See SCR Subsection 575.01.

#5There is no bid item for nester guardrail.

There should be a bid item for G‐4 w‐beam guardrail long span system, tl‐2 as shown in the plans. Once again if this is lumped in with the standard w‐beam guardrail item, and the quantities are incorrect, the contractor takes a loss due to the 3% over run.

The bid price for G4 guardrail is for the complete system, including nested rail elements. Include those costs in the 61701 bid items. Measure the actual quantities of work performed according to Section 109.

This question is posed by the Contracting Officer: What is the "Project Plan" (file name:
