Handbook for Bridge Inspections - TSP2

8.4 Measurements
Forms have been developed in BRUTUS for recording the follow·
ing measurements:
* Levelling
* Horizontal distances/di splacement
A form for general use is avai lable for other measurements.
The forms are based on Microsoft Excel spreadsheets linked to the
BRUTUS International inspection module. The identity of a bridge
is transferred directly from BRUTUS International when a new
measuremenl fonn is drawn up. An already existing Excel form
containing previous measurements should continue to be used
for recording new measurements of the same type.
Recording and Making
Reports
The foll owing data must be recorded and reported:
* Date when measurements were taken
* Which type of ins peel ions the measurements relate to
* The intervals at which the measurements were taken, especially
if this deviates from the inspection intervals
* Those taking the measurements and, possibly, the person ulti
mately responsible for them
* Time/temperature/weather conditions. Additionally, for levelling
the following factors should be included:
measuring horizontal distances/displacement
height of sag
vertical distances
headroom
* Type of measuring equipment used
* Other comments such as special weather conditions, deviations,
and other infonnation which could be important for interpreting
the results
* Location on tbe bridge wbere the measurements were taken - see
Chapter 2.4 " Location of Measurements".
* Results of the measurements
It may be worthwhile presenting the results of, fo r example, a
Special Inspection in an extended report incorporating tables and
visual di splays. After levelling has been carried out, profiles could
be portrayed both lengthways and transversely; the results can be
shown together with previolls measurements and even theoretical
values.
The results of measurements taken should be di scussed and
assessed and will then fonn part of the process of establishing the
degree of any damage, its consequences and cause(s).
