1.1 This specification covers the manufacture and purchase requirements of products used for the assembly and construction of circular vertical precast reinforced concrete manholes and structures used in sewer, drainage, and water works. 1.2 Part I, Sections 1 – 11, of this specification presents general requirements and requirements that are common to each precast concrete product covered by this specification. 1.3 Part II of this specification presents specific requirements for each manhole product in the following sections:
Note 1: Future products will to be included in Part II in a
future revision of this specification.
1.4 This specification is the inch-pound companion to Specification C478M; therefore, no SI equivalents are presented in the specification. Note 2: This specification is a manufacturing and purchase
specification only and does not include requirements for backfill,
or the relationship between field load conditions and the strength
requirements of the manhole products and appurtenances. Experience
has shown, however, that the successful performance of this product
depends upon the proper selection of the product strength, type of
foundation and backfill, and care in the field installation of the
manhole products and connecting pipes. The owner of the project for
which these products are specified herein is cautioned to require
inspection at the construction site.
