Advisory Notes for Tenderers for Government Contracts

As part of the current procurement reform process, new documents have been developed for regular use for Government procurement. These new tendering documents are radically different from earlier ones and have been completely re-designed. Tenderers should study the documents carefully before preparing their offers to ensure compliance with the key requirements of the document. The following are a number of pointers that Tenderers should take into account when preparing their Tenders. 1. Pricing form and Tender form

The Pricing form must be completed including any emergency services if required by the Technical specifications. The total figure of the Price Schedule must be taken to the Tender form but not including any required emergency services. The Tender form is the offer you are making. One Tender form must accompany each Pricing form and must be signed and completed. You must also provide the emergency call-out costing if required. If it is not completed and signed, your tender will be rejected at the preliminary stage of evaluation.

2. Documents required

You must provide the documents stated in the Instructions to

Tenderers and the Tender Data Sheet including the certificate of site

visit if a site visit is indicated as compulsory. Failure to provide any of

the documents specified may result in rejection of your tender.

3. Qualifications form

The Qualification Forms provided at Annexes A and B must be

completed for each type of equipment that the tenderer is offering to

service.

4. The Contract form

INVITATION TO TENDER FOR THE SUPPLY 5

The Contract Form contained in the Tender Document is an example

for information and will only be signed by the successful Tenderer

following an award of contract.

This advisory is given as assistance only and Tenderers must examine

all forms, instructions, terms and specifications when preparing their

offer.
