Article 23 -  Suspension  23.1. The contractor shall, on the order of the contracting authority, suspend the execution of  the contract or any part thereof for such time or times and in such manner as the  contracting authority may consider necessary. The suspension shall take effect on the day  the contractor receives the order or at a later date when the order so provides.  23.2. Suspension in the event of presumed breach of obligations or irregularities or fraud:  23.3. During the period of suspension, the contractor shall protect and secure the supplies  affected at the contractor's warehouse or elsewhere, against any deterioration, loss or  damage to the extent possible and as instructed by the project manager, even if supplies  have been delivered to the place of acceptance in accordance with the contract but their  installation has been suspended by the project manager.  23.4. Additional expenses incurred in connection with such protective measures may be added  to the total contract price, unless:  a) otherwise provided for in the contract; or  b) such suspension is necessary by reason of some breach or default of the contractor;  or  c) such suspension is necessary by reason of normal climatic conditions at the place of  acceptance; or  d) such suspension is necessary for the safety or the proper execution of the contract or  any part thereof insofar as such necessity does not arise from any act or default by  the project manager or the contracting authority or  e) the presumed breach of obligations or irregularities or fraud mentioned in article  23.2 are confirmed and attributable to the contractor.  23.5. The contractor shall only be entitled to such additions to the total contract price if it  notifies the project manager, within 30 days after receipt of the order to suspend the  contract, of its intention to claim them.  23.6. The contracting authority, after consulting the contractor, shall determine such additions  to the total contract price and/or extension of the period of performance to be granted to  the contractor in respect of such claim as shall, in the opinion of the contracting authority,  be fair and reasonable.  23.7. The contracting authority shall, as soon as possible, order the contractor to resume the  contract suspended or inform the contractor that it terminates the contract. If the period of  suspension exceeds 180 days and the suspension is not due to the contractor's breach or  default, the contractor may, by notice to the contracting authority, request to proceed with  the contract within 30 days, or terminate the contract.
