Plan Sheet / Specification Reference=Item 28, Roadway Excavation, Special Provision Section 10-1.30

The referenced section includes "foundation treatment of 0.9M" wherein 0.6M is to be removed and 0.3M is to be treated and compacted in place.  What depth of is to measured for payment, 0.6M or 0.9M?

  • See Addendum No. 1.

Q:05/24/01
R:06/22/01
Plan Sheet / Specification Reference=Item 28, Roadway Excavation, Special Provision Section 10-1.30

There is no item nor Spec Section for "Ditch Excavation".  The plans and sections depict a ditch alongside the roadway that is 2.4M wide at the bottom.  The Standards provide that the excavation required to construct a ditch with a bottom width of less than 4 meters will be classed as ditch excavation.  Why isn't this work classed as "Ditch Excavation"?

  • Paragraph 3 of Section 19-4.03 PAYMENT within Section 19-4 DITCH EXCAVATION in the Standard Specifications states:
    The excavation of gutters within the median area of a divided highway,
    and gutters between the roadbed shoulder and an adjacent excavation 
    slope, and gutters in excavation benches, and side gutters contiguous
    to embankment slopes, all as shown on the plans, will be paid for as
    roadway excavation and payment will not be made as ditch excavation
    for that work. 
 
  • Standard Plan A62A EXCAVATION AND BACKFILL MISCELLANEOUS DETAILS; detail ROADWAY EXCAVATION - DITCH EXCAVATION shows that any ditch regardless of shape within the roadway prism shall be paid for as Roadway Excavation. Addendum No. 1 states that  the ditch excavation from Station 294+85 "G" to 297+45 "G" Line will be measured and paid as roadway excavation.

R:06/22/01
Plan Sheet / Specification Reference=Item 28, ROADWAY EXCAVATION, FOUNDATION TREATMENT

The job cross-sections indicate that the 0.9M depth of foundation treatment can be "superseded" by the structural section if the fill from o.g. to f.g. is something less than the thickness of the structural section.  In such cases, the "foundation treatment" could be only or few millimeters or even nil. Is this true?  Is this what is required/desired/intended?

  • See Addendum No.1.
