Inquiry #2: Ref Contract Items 50 and 51, Special Provision Section 10-1.45 and Detail for " MBGR Wood Post Mod" on plan sheet 23 (C-1).Please define by special provision, how the additional rail element shown on the detail is to be paid. Section 83-1 of standard specifications for method of measurement and payment, refrenced in 10-1.45 appears to be ambiguous for the work shown on C-1. Suggest you check for precedent on this subject in District 7, for similar issue(s).
Inquiry submitted 11/05/2012

Response #1:The cost of additional rail element is covered under bid items 50 and 51, therefore no separate payment will be made for additional rail element. The article 83-1.04 of the standard specs indicates full compensation for the types shown in the Engineers estimate is included in the prices paid per the linear foot for railing. You can bid each type separately since there are three different bid items for guard railing.
