Federal approach to contaminated sites: statements of work for historical review
Purpose
This Statement of Work (SOW) covers methods to be used and deliverables to be submitted by a consultant when conducting a Historical Review (also known as a Phase 1: Environmental Site Assessment, as per the Canadian Standards Association) of a suspected contaminated site for the [name of organization].
Site information
This SOW applies to a Historical Review to be conducted at [location]. [This section is to be filled out by the contaminated site manager and should include general information pertaining to the sites being examined. For example, it should include information on known suspected areas of contamination, the types of contaminants that the contractor can be expected to find, key problem areas, etc. This information should be general and will vary in content depending on the number of sites.]
General
The Historical Review includes compilation and review of sufficient information to identify and evaluate:
- the physical condition of the site and its geology, hydrogeology, facilities and surroundings;
- past and present site processes, operations, waste disposal practices, etc.;
- potential contaminant pathways and key ecological receptors;
- health and safety considerations;
- regulatory agency concerns;
- proposed future land use and adjacent land uses;
- potential problem areas and contaminants of concern; and
- the approximate scope of required site investigations.
References
The following references are listed as guidance documents. This is not an all-inclusive list; therefore, the contractor shall ensure that all applicable references are used. Should more current versions become available during the life of the contract, they shall take precedence and be referred to in subsequent work/reports. With the exception of [federal department and section] policy documents and previous assessments completed for the property listed herein, copies of other references will not be made available.
- [Federal department and section] policy documents;
- [Previous assessment reports such as environmental audits, environmental site assessments, environmental baseline studies, well drilling and geotechnical reports]; and

- Letter of Interest
Contractors wishing to bid on the work shall submit a Letter of Interest to the Project Manager at [location] on or before [date - a minimum of 2 weeks should be given to the contractors to review the pertinent information]. The letter is to provide a condensed version of the technical and management information requested in the full proposal (next section) and an overall cost estimate. The letter shall not be more than six (6) pages in length (3 leaves, double-sided) on 8½" x 11" paper, and the text shall be written in 12 point font. Only the first six pages will be reviewed and scored. The letter will be used to evaluate and select the contractor to carry out the work. If additional information is required prior to making a selection, the four (4) contractors with the highest score will be invited to submit full proposals.
It is recognized that industry spends a great deal of time, effort and money to develop proposals. By taking this approach, [Name of organization] assures technical credibility and cost effectiveness without asking every contractor to expend time, money and resources to produce full proposals.
- Full Proposal [if required]
[Time period - 3 weeks is suggested] following the bidders' conference, four (4) contractors will be notified of their eligibility to submit their full proposals to [specified address] on or before [date/time]. The proposal is to be submitted in [three] copies outlining the approach to the Historical Review, a proposed work schedule, a detailed cost estimate for the work and the contractor's relevant experience in carrying out similar work. The proposal should display a logical, structured approach and include the necessary information to address the evaluation criteria.
Evaluation criteria
- General
Both the Letter of Interest and full proposal will be evaluated and scored in accordance with the following criteria. Contractors must cover each criterion. Proposals should expand on the requirements stated in the SOW and describe how the contractor plans on meeting the work requirements.
Item | Criteria | Weight |
---|---|---|
1. | Understanding of Scope, Objectives and Possible Problems | 15 |
2. | Approach and Methodology | 35 |
3. | Level of Effort | 20 |
4. | Managerial Experience | 30 |
Total | Blank | 100 |
- Technical Proposal
- Understanding of Scope, Objectives and Possible Problems. The bidder should demonstrate a comprehensive understanding of the project's scope and objectives. As well, the contractor must demonstrate that direct and peripheral problems have been anticipated. Proposed solutions to anticipated problems must be presented.
- Approach and Methodology. The proposed approach and methodology should follow an efficient and logical sequence that will fulfil the requirements of the Statement of Work. The proposal should describe the general approach to the historical review and the reference documents that will be used. The contractor should demonstrate its ability to competently evaluate the results and provide meaningful recommendations. A work schedule should show that the project milestones and objectives, both technical and administrative, will be met.
- Level of Effort. The contractor should show that a sufficient level of effort will be applied to address the technical requirements of the project in an efficient and cost-effective manner. Proposals will be evaluated on their value-for-money, where value is interpreted as the quality and quantity of work to be done in direct support of the project. Full proposals shall include a breakdown of anticipated work by task and quantity, including:
- management and supervision;
- research; and
- disbursements.
- Management Proposal
Managerial Experience. The contractor should demonstrate that its organization, including partners and subcontractors, has the necessary technical and managerial background and experience. Include the background, experience, geographic proximity to the project site and level of involvement by task for each key individual. The contractor should also demonstrate technical background and experience by citing projects of comparable scope and nature that show successful and timely completion (include client references and their points of contact). Indicate other tasks the key individuals may have during the project. The backup for key personnel should be named.
- Contractor Selection
Selection. Selection of the contractor may take place based on the information provided in the Letter of Interest, or, depending on the complexity of the project, it may be necessary to ask contractors to submit their full proposals.
Letter of Interest (LOI). The bidder selected for contract award or invited to submit a full proposal will be the contractor that:
- addresses each evaluation criterion in sufficient depth to allow proper evaluation;
- obtains a proposal evaluation score of 75% or higher in each category;
- meets all the mandatory requirements set out in the Request for Proposal; and
- obtains the highest final score on 100, which includes both the technical proposal and cost. The technical proposal score obtained following the evaluation will be recalculated in relation to a maximum of 90. The lowest budgetary price will get a score of 10, with the next lowest getting 8, 6, 4, 2 and 0. Contractors should be prepared to commit to the budgetary price.
Full Proposal. If full proposals are requested, the four (4) highest scoring bidders will be asked to submit Full Proposals. Where more than four (4) LOIs score above 75% and where the scores are tightly grouped, up to six (6) bidders will be invited to submit full proposals. The successful contractor will be the one meeting the technical requirements specified in the previous paragraph and obtaining the highest score on 100, including both the technical proposal score and the cost score within the proper budget ceiling of $ [insert average budget price].
