Equal to Best Concrete.
The city council Monday night. fol-
lowing 4 somewhat stormy caucus late
in the afternoon, amended the specifi-
cations for concrete paving. The words
'granitoid blocking are eliminated
from the specifications, and wearing
surface specified one part cement to one
part sand and one part crushed granite
pebbles or trap rock screenings. In
stead of combined curb and gutter
the specifications now call for curbing
without a gutter, and the pavement
a few alleys were eliminated, and a
new resolution of necessity adopted.
City Solicitor Northup said today
that he could see no reason why any
contractor could not bid on the amend
ed specifications We have specified
no patented formula" said Mr.. Nor
thup and we do not specify any pat
ent filler for the expansion joint. AS
far as the so per cent of a certain size
of granite or other material in the top
course is concerned, 1 think that con-
tractors will be able to furnish the
same thing in any material"
In the caucus in the afternoon Mr.
Northup was asked for an opinion as to
whether the amended specifications
would permit contractors to lay con-
crete pavement in Marshalltown with
out Infringing on the Blone & Sinek
patents, and it was on his assurance
that the new specifications would open
the bidding to all contractors, without
infringement upon patents that it was
agreed TO make the vote unanimous.
Mr. McCarten, councilman Large,
presented the resolution to reconsider
the resolution of specifica tons for
granitoid concrete. and calling for them
to be set aside and vacated. This was
adopted unanim ously, with all members
present.
