Quality checking / Testing
Except in the case of special, further laboratory examinations or the extraction of larger cores e.g. from floor constructions, the creation of countless thousands of square meter large levelling surfaces or the like, the preparation for the site visit, the management as well as the execution of all other inspection measures on the spot and in the laboratory up to the finalized report will be accomplished solely by the expert witness graduate engineer F. Schüppenhauer.
The comparison of actual conditions and necessary conditions is the heart of the expert witness examination.
Such examinations should always take place when they seem necessary from the technical point of view and are found to be financially adequate.
To approach a task with the motto: "I have seen that a thousand times, I know at first sight what the problem is." could not only be dangerous for the expert witness – even so, if he is right with his technical evaluation.
In the particular case only the actual existing and verified specific values of the material will permanently last for the overcoming problems and disputes.
Naturally at the same time we have to consider that for example for any client costly examinations to find out why the screed doesn’t have the required consistency, usually are from secondary interest, if this client has a prime contractor to build the object.
In this case the underlying cause for the insufficient consistency of the screed would be unnecessarily.
In the following I will show you a very few selected problems and complaints as they have occurred during my long-term work as expert witness
(about 1.800 reports).
Examples:
2.
Hollow layers (often with netcracks)
3.
Surface strength of concrete and screeds
5.
Parquet, floorboards and offers: Different and/or extra-wide joints width; bowing of parquet rods
6.
Puddles, flatness, descent
8.
Blistering and seperations
9.
Creaking dry screed (chipboard)
11.
Blistering (filled with fluid)
14.
Deformation and impacts
15.
Cross slope and length flatness in high rack warehouses
17.
Cement screed with ceramic tiles
18.
Assess the electrical resistance, dangerous electrical charge, sparking
