23.15.1 does not reply to Sub-hubco in writing within ten (10) Business Days of the date of Sub-hubco's notice with a programme for carrying out the relevant Authority Maintenance Obligations within a period of time that is reasonable having regard to the nature of the breach, the reasonably foreseeable consequences of non-performance of the relevant Authority Maintenance Obligations for the Services and Sub-hubco's obligations under this Agreement; or
23.15.2 having provided such a programme, does not comply with it,
Sub-hubco shall be entitled to perform the Authority's Maintenance Obligations so far as necessary to prevent any reasonably foreseeable adverse effect on the Services and/or Sub-hubco 's obligations under this Agreement consequent upon the non-performance of the relevant Authority Maintenance Obligations.
23.16 Sub-hubco shall not carry out any Sub-hubco's Remedial Services unless and until the Authority's Representative, pursuant to this Clause 23.16, has approved or is deemed to have approved or has specified the proposed commencement date, the proposed hours of work and the estimated duration of Sub-hubco's Remedial Services (together the "SRS Timetable"). Sub-hubco must give the Authority not less than [twenty (20)] Business Days notice of its proposed SRS Timetable.

23.20 The Authority must reimburse Sub-hubco all reasonable costs that it incurs in carrying out and performing Sub-hubco's Remedial Services in accordance with this Clause 23.

23.21.1 making good any defects in plaster and other interior wall and ceiling finishes and decoration [and floor coverings referred to in Clauses 23.13.2 and 23.13.3] provided by Sub-hubco as part of the Works or in implementing an Authority Change, caused by defective design or workmanship in the carrying out of the Works or in implementing the Authority Change; and
23.21.2 making good any defects in plaster and other interior wall and ceiling finishes and decoration [and floor coverings referred to in Clauses 23.13.2 and 23.13.3] provided by Sub-hubco as part of the Works or in implementing an Authority Change (whether or not these have subsequently been replaced or renewed by the Authority [and things referred to in Clause 23.13.4]) consequential on any Programmed Maintenance or Unprogrammed Maintenance or any act or omission of Sub-hubco.
