Back to Table of Contents
This section contains material specifications. The material specifications
are from the NRCS’s National Engineering Handbook (NEH) Series Part 642
(formerly referred to as NEH Section 20) as well as several state interim
specifications. The interim specifications are numbered starting at 800. The
material specifications along with construction specifications (see
Section 5) make up the contract specifications and can be used as the
requirements in construction contracts. The materials selected will be shown on
the drawings and/or also in the construction specifications.
See the general discussion
in Section 5 for a description on specifications (construction and material)
and their use in construction contracts.
Current updates of material specifications from NRCS's National Engineering
Handbook Series Part 642 can be found at http://www.ftw.nrcs.usda.gov/nehms.html. The notice for the May 2001 release
of the construction specifications in Part 642 identified revisions to Material
Specification 523 - Rock for Riprap and Material Specification 581 - Metal.
These changes are reflected in this release of Chapter 6 of the Illinois Urban
Manual. The dates on the other material specifications have not been updated;
however, the technical content of all other material specifications has not
likely changed.
This section was updated in November 2002.
