APPENDIX 1
WARRANTY AND GUARANTEE SLIPPING
1. WARRANTY
The Contractor, or his appointed agent, is required to have (i.e. the Contractors own
shipyard or that an arrangement has been made by the Contractor with a local shipyard or
repair yard in the HKSAR) substantial and established ship repairing/servicing shipyard
facilities in the HKSAR capable of servicing all aspects of the Pontoon during the currency
of the warranty period under Clause 16 of the General Conditions of Contract, including
guarantee slipping as stipulated in this specification. Full details of the repairing/ servicing
shipyard facilities including establishment, repair equipment/Pontoons, etc. shall be
submitted with the tender.
Purposes of requiring a repairing/servicing shipyard is to facilitate rectification of the
warranty defects without delay to the Pontoon's operation. As such, the Contractor should
give full authorization to the repairing/servicing shipyard or agent in the HKSAR for
making decision on validity of the warranty claims. If such authorization is not given, the
Contractor should specify in the tender the means by which the repairing/servicing shipyard
could receive immediate agreement from the Contractor, so that rectification of the
warranty defects could be carried out in the most fast and efficient manner.
For those equipment to which the manufacturer/supplier does not offer one-year warranty
on each equipment, in this case the shipbuilder should arrange repairs for the remaining
warranty period at his own cost, i.e. the tenderer must at its sole cost and expense either (i)
provide the warranty for a continuous period of 12 months commencing on the delivery of
the Pontoon; or (ii) procure the manufacturer/supplier to provide the warranty for a
continuous period of 12 months commencing on the delivery of the Pontoon. No
counterproposal by the tenderer will be considered by the Government. For other loose
equipment and installation, such as life saving and fire fighting equipment, etc., which are
required to be serviced, inspected or renewed annually, shall have a validity period of not
less than 10 months from the delivery date of the Pontoon. These items shall not include
machinery, electrical and electronic equipment.
The Contractor should also follow the details / procedures stipulated in this section to
implement his warranty obligations. During the warranty period, when the Pontoon is
handed over to the Contractor, or his representative/agent for rectification of Contract
outstanding items, warranty repair and/or guarantee slipping, the Contractor shall beresponsible for the due return of the Pontoon in good order. Should there be any loss or
damage caused by any reason while the Pontoon is in the possession or control of the
-
7/29/2019 Procurement for Pontoon Bridges
24/83
24
Contractor or his representative/agent, the Contractor shall pay for the cost for the loss or
damage plus 20%. During such period, and until the Pontoon is returned to MD, the
Pontoon is deemed to be at the Contractors risks, and the Contractor shall insure and keep
insured, at his own expense, for an amount of not less than the purchase price of the
Pontoon plus 20% to protect the Government property against any risks of damages.Certificate of Insurance and evidence showing premium being paid shall be available for
inspection in advance.The Contractor should provide this insurance policybefore the
signing of Contract.
1.1 Total Pontoon Warranty
It is required that the Pontoon is covered by the Contractors warranty for one year after the
date of acceptance of the Pontoon. It is intended that this warranty cover the entire Pontoon
and all its associated equipment, fittings and outfit (including spare parts, documentation
and repair by replacement items) against defects of design, construction and failure of
materials. This warranty may be backed up by the Contractor using individual equipment
suppliers/manufacturers warranties but the Contractor shall remain solely liable to MD for
such warranty. Notwithstanding and without prejudice to the Contract on warranty
obligations for the total Pontoon, any individual equipment supplier/manufacturers warranty
extending beyond the one year total Pontoon warranty must be passed on to MD as
appropriate.
1.2 Procedures for Warranty Claim
A detailed procedure for dealing with warranty claims must be proposed by the Contractor
and agreed by MD before acceptance of the Pontoon. This should be based on the following
principles:
(a) Warranty for total Pontoon between MD and the Contractor.
(b) Notification of claimed defect to be sent from MD to the Contractor by a defined route.
(c) Joint inspection to agree defect and remedial action to the satisfaction of MD.
(d) The Contractor should undertake as far as practicable and reasonable on-site warranty
services/repairs (including parts, labour and transportation cost).
The Contractor will be expected to undertake all defect rectifications at his expense and
using his own facilities, resources, etc. As such any Contractor must have suitable facilitiesin the HKSAR to undertake his obligation under the warranty. This is considered by MD to
mean a minimum of established repairing/servicing/yard facilities capable of servicing all
-
7/29/2019 Procurement for Pontoon Bridges
25/83
25
aspects of the Pontoon.
The Contractor shall be responsible for rectification including repair and replacement as
necessary for warranty claims. This shall, at no cost to MD, include services described in
the following sub paragraphs:
(e) To attend to any requirement for inspection and repair within 24 hours (excluding
Hong Kong public holidays) of receiving the report of a fault and to take immediate
action of rectifying the fault after inspection. MD should be informed of what the
rectification action has been taking within 48 hours of receiving the above-mentioned
report.
(f) To provide all necessary transport, labour and material, tools and testing instruments
required for the warranty repair service.
(g) The Contractor shall bear all costs, insurance, risk of labour and transportation for
agreed warranty claims.
If the Contractor fails to response against any reported warranty claims within 48 hours
at no reason, MD may arrange defect rectification as deemed appropriate with a view to
minimizing any downtime incurred. In such case MD should reimburse the cost of
such repairs from the Contractor afterwards.
1.3 Extension of Warranty
The warranty period for all goods requiring service under warranty shall be frozen
whilst the Contractor fails to repair and correct satisfactorily all defects within an
agreed and reasonable period.
1.4 Recurrent Defects
During the warranty periods specified above, should a second and similar defect arise,
this shall be construed as conclusive evidence of the equipment's unsuitability for the
purpose intended, and the Contractor shall take immediate steps to conduct a thorough
investigation jointly with MD at the Contractor's expense, to ascertain the reasons for any
such defect and shall forthwith at MD's option and the Contractor's expense, manufacture
and effect delivery of equipment with a new design suitable for the purpose intended to
replace those defective.
2. ITEM S TO BE PROVIDED DURING THE WARRANTY PERIOD

2.1 Updated/Upgraded Information
It is expected that during the warranty period certain equipment may be modified or
changed. All documentation affected by this change must be updated to reflect the new
situation. A system for configuration control must be set up and rigorously applied to ensurethis work.
2.2 Support Information
The above principal applies particularly to support documentation. At the expiry of the
warranty period it is required that the Contractor should provide a means of reproducing
these items to allow future modifications to the Pontoon to be input into the system.
3 GUARANTEE SLIPPING
As stated in the section "Warranty" above, guarantee slipping shall be carried out at the end
of the 12-month warranty period.
At the guarantee slipping, the Contractor shall carry out the following work with all the
necessary cost, labour, materials and paint, etc., provided by the Contractor.
