Tender Preparation and Herbicide Specification

Tender Preparation and Herbicide Specification
An employer or organisation (client) considering contract application of pesticides has a duty to comply with relevant legislation. They must also have an awareness of the potential impact such activity may have on the environment and be suitably trained to undertake the tasks they are called upon to perform. It is therefore essential that the employer or organisation (client) carefully consider the tender preparation and management of the contract to cover the following areas. This may require additional staff training or obtaining relevant expertise.

1.1 Policy on the Use of Pesticides
The client should have in place a Policy document which sets out their attitude towards the use of pesticides on areas under their jurisdiction. This should show that alternative methods of control have been examined and that environmental and public considerations have been taken into
account. The minimum pesticide for the job should be used.

1.2 Objective
There should be a clear understanding of the cause and effect of the problem to be treated, and the objectives to be achieved by the contract. The conditions of the approval of the product should also be met.

1.3 Legislation
The client must have a knowledge and understanding of all current relevant legislation and codes of practice relating to the supply, storage and use of pesticides, as there is a responsibility and duty on the client to ensure that such legislation is complied with by both their own and a contractor's employees.

1.4 Employees
The client should have sufficient trained and appropriately qualified (preferably BASIS certificated) staff and / or advisors to undertake the preparation of tender documents and the monitoring of the contract. Details of specific items like the type of pesticide to be used, timing, dose rate etc. should only be incorporated into the specification by those clients with access to staff who have the relevant expertise and competence.

1.5 Performance Standard
The client must be clear as to the standard of control required (this will not necessarily be 100% control) and that it is possible to achieve, taking into account any limitations on the selection and use of technique or pesticide brought about by legislation and / or environmental requirements. In particular, the performance standard should recognise the performance criteria described by the product label. In all circumstances the performance standard required must be realistic.

1.6 Areas for Treatment
There should be available for the purposes of the contract a clear definition of the areas to be treated including any relevant measurements, maps and plans. Maps should clearly show areas of risk such as water bodies, SSSIs, Nature Reserves, schools, hospitals, old peoples homes etc.

1.7 Contractors
The client should prepare a contractor profile covering quality, capability and skills requirements, and undertake an assessment of possible contractors to determine if they are potentially able to meet the conditions of the tender. This assessment must include information on the contractor's experience and competence in carrying out similar work, and the number of qualified employees that the contractor can make available to carry out the specified work, at the dates / times requested.

1.8 Monitoring
The client must have in place a programme for monitoring the contract to ensure that the tender conditions, specifications, performance and standards of control are met, and that appropriate records are maintained and submitted. Persons undertaking the monitoring should be suitably trained and competent.

1.9 Communication and Incident Control
There should be in place a 'Communication / Incident Plan' to ensure that any incident arising from the execution of the contract, which may be a possible cause for concern, is efficiently and speedily dealt with.

1.10 Review
An annual review of all aspects of the contract should be undertaken to ensure compliance with any changes in policy, legislation, controls or any other factor likely to affect its performance. The contract should feature a break clause to allow any such changes to be reflected in the contract if the policy or legislation changes.
Contract Specification
To derive maximum benefit from the contract it is essential that the initial specification is well defined in terms of scope, methods of working etc. However, there is a need for caution when dealing with pesticides because of the complex legislative requirements. A high degree of expertise and competence is required by staff drawing up the specification. The model below is based on the assumption that such expertise is available. In all other cases the client will need to adapt the model according to the level of expertise.

2.1 Introduction
Initial clauses in the tender should cover the client's standing orders, conditions of contract, Insurance requirements etc.

2.2 Work to be Undertaken
Statement on the type and scope of work to be undertaken providing schedules or appendices giving specific detail relating to areas for treatment including appropriate measurements, information on any unusual hazards, anticipated work/building works and any restrictions on working hours or machinery that may be used. Any specific instructions for working in or near areas of risk as defined in paragraph 1.6 should be included.

2.3 Standard of Control
The standard(s) of control the client requires for each aspect of the contract must be clearly stated and realistic, taking into account performance limitations of the chosen pesticide e.g. the efficacy/persistence of the pesticide chosen, plus environmental considerations and the start date of the contract.

2.4 Pesticide Specification
a) The pesticides (written as active ingredients) and rates of application to be used on this contract are as follows/as per schedule x

The contractor must provide with his tender a list of the proprietory products, including MAPP/HSE Nos., he proposes to use, (including equivalent alternatives) together with rates of application for each section of the contract.

OR should the client wish to place the onus on the contractor to specify the pesticides he would propose to use to achieve the performance or standard of control required in this case the contractor should have a BASIS Certificate in Crop Protection.

b) The contractor will provide a schedule of the pesticide(s), including MAPP/HSE Nos., he proposes to use for each section of the contract covered by clause 2.2, giving rate(s) of application and number of treatments he considers necessary to achieve the standard of control as per clause 2.3.

b) Ensure that the pesticide specification is sufficient and suitable to achieve the performance standards set. Ideally this should be set by a BASIS Certificate holder;

c) Decide on frequency of site inspections;

d) Prepare a check list of the areas to be assessed during site inspections.
2 Tender Submissions
Examine tender submissions to determine if all the requirements called for in the tender documents are met including the provision of appropriate documentation. If any documentation is missing, the tenderer should be given an opportunity to forward the missing documentation.
