In accordance with our promise, we have made estimates of
cost of renewing your Ran Jacinto St. bridge on two bases; first, -by
using an ordinary swing span similar to the old one biit involving all
the latest improvements in bridge designing; and, second, by putting
in a new type of bascule over the river and a deck trestle over the
railroad tracks, in both designs using a similar deck trestle at the
other r,ide of the river.
We had anticipated that the bascule striioture would prove to
be a trifle cheaper than the other, but have been disappointed, for our
figures show that the contrary is the case, the total cost of complete
bridge with bascule being $37,000.oo, and that of the corresponding
bridge with a swing span $35,000.oo. These figures are based on
present prices of materials, and do not include any allowance for
engineering, royalty or inspection — they are simply our estimates of
the least amounts that would be bid today in competition for the new
superstructure, the operating electrical machinery and the necessary
modification of and repairs to the existing substructure.
In iut opinion, the bascule is by far the better bridge for
the location, notwithstanding its slightly greater price; for, under
all ordinary conditions, it can be opened and closed in less than half
the time that would be required by the horizontally rotating draw.
As we control the patents on the bascule, it was our intention
to ask you a royalty in addition to our regular fee for plans and
