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


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


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


26/83

26

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
