Example of a diary and measuring schedule of a floor layer with two measuring samples used for reconstruction of a whole shift (task module: laying carpet; M1 and M2 = measurement samples)

Time	Task (derived from the diary)	Measurement	Kneeling/squatting	Reconstruction
07.00–07.30	Approach (driving)		–	Non relevant
07.30–08.00	Preparation of worksite		–	Non relevant
08.00–08.30	Application of glue	M1	×	M1
08.30–10.30	Laying carpet	M2	×	M2
10.30–11.00	Application of glue		×	M1 copy
11.00–12.30	Laying carpet		×	M2 copy
12.30–13.00	Break		–	Break
13.00–13.30	Preparation work		–	Non relevant
13.30–14.00	Application of glue		×	M1 copy
14.00–15.30	Laying carpet		×	M2 copy
15.30–16.00	Clearing of worksite		–	Non relevant

Non relevant = none of the defined knee-straining postures occurred
