Municipal engineering; Sanitary engineering
“Plans should be neatly and clearly drawn, the cross sectional
dimensions and the gradient being written on the _plan_ of sewers; there
should be a title and scale on each plan, as also on each sheet, and the
date with the name of the engineer or surveyor clearly written so as
easily to be read; this as a rule should be in the right-hand corner.
Many names are so written that experts cannot read them, and plans are
frequently sent out having no title, nor any scale, nor any name.”
“Plans of details, such as side entrances, man-holes, flushing chambers,
and sewer ventilating arrangements, should be at 4 feet to an inch,
larger works may be at 4, 10 to 20 feet to an inch. Clear understandable
and measurable details are desirable . . . I have much trouble in
looking over defectively prepared plans and crude ill-understood and
ill-digested schemes as they are submitted to the Local Government
Board, for approval and sanction to a proposed loan. One great fact
connected with the Board must not, however, be overlooked. It is not an
office of works, it does not undertake to devise neither does it make
itself responsible in any degree for the plans or for the estimates
which may have been sanctioned. Each engineer and each local authority
must both devise and execute the local works, and the district must
alone be responsible for the local expenditure. The Board neither
dictates as to works, nor superintends works, but reserves the power of
refusing sanction to a proposed loan, and of requiring full explanations
as to failures in the works, or as to expenses over estimates before
sanctioning a supplemental loan. The reason that the Board declines
responsibility ought to be clearly manifest; plans and details may be
the best possible, but the ultimate result depends on daily local
supervision, and this the Board does not give; neither local action nor
local responsibility is superseded.”
Speaking on this point at the first meeting of the Sanitary Institute of
Great Britain held at Croydon in 1879, Captain Douglas Galton, C.B.,
says:[251]
“Where a loan is applied for, the plan upon which the money is to be
spent is submitted for Government approval. The Government only lends
the money after the approval of the proposed scheme of expenditure by
one of their inspectors.”
“The Local Authorities of the towns to be drained cannot therefore be
responsible for the plan selected, for the Local Authorities must alter
their plans to suit the views of the inspector. The responsibility of
the engineer is diminished, because he may be compelled to modify his
plan in a manner in which he may not thoroughly approve, and the
inspector has no responsibility in the matter, because, after having
approved of the general scheme, he has no control over the details or
the execution of the work, nor can he be in any way held responsible, if
the result were a failure.”
