It applies to periodic maintenance of surface repairs and other repairs too

Periodic maintenance will apply to other repairs also but the same should be related to surface dressing.

Applies to both Period maintenance and other repairs.

The clause specifically provides that it should apply to periodic maintenance with surface dressing AND other repairs

The use of words AND in the clause is significant

You cannot take the plea that it would apply only to other repairs.

you can have my contact details from the website kaanoon.com

It is clear that the clause includes the whole thing and not particularly about 'other repairs' alone.

1. Both the items have been joined with the word 'and'.

2. So, both the periodic maintenance with surface dressing and other repairs shall have to be done as required as per the terms of the contract.
