This Statement of Work (SOW) has been developed by [name of organization] to solicit consulting services for an Initial Testing Program (also known as a Phase II: Environmental Site Assessment as per the Canadian Standards Association).
This SOW applies to an Initial Testing Program 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.]
The Initial Testing Program involves an initial characterization of on-site contaminants and/or identification of off-site contaminant source(s) that may have affected the site. The objectives of the Initial Testing Program are to identify:
- types and concentrations of contaminants, general locations of contamination, and affected areas; and
- detailed soil, geological, hydrogeological and hydrological conditions on and adjacent to the site.
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 [contaminated site manager's organization] policy documents and previous assessments completed for the property listed herein, copies of other references will not be made available.

Scope of work
To meet the objectives of this mandate, contractors will carry out the following work, subject to site-specific environmental issues or other factors:
- Design a field sampling and analytical program to characterize potentially contaminated areas identified by the Historical Review (Phase I: Environmental Site Assessment). The proposed program should include (but may not be limited to) the following:
- a Health and Safety Plan encompassing expected site hazards, location(s) and directions to the nearest aid facility, personal safety equipment requirements, personnel and equipment decontamination procedures, exclusion zones and restrictions to public access, site health and safety rules, and preventive measures;
- identification of media to be sampled and appropriate sampling equipment and procedures;
- sample preservation and shipping requirements;
- proposed analytical procedures;
- field and laboratory QA/QC procedures and measures;
- proposed sampling locations, with an explicit rationale for those locations;
- description of test pitting, borehole and monitoring well installation and development procedures;
- screening methods (e.g. photo-ionization detector (PID), olfactory, visual) to be used;
- non-intrusive investigation methods (e.g. geomagnetic, ground-penetrating radar) to be used;
- georeferencing of sample locations (e.g. land survey);
- expected end-point for data (e.g. hydrogeological/contaminant loading model; preliminary volumetric estimate of contaminated material, preliminary ecological risk assessment, etc.);
- communications between the contractor, land owner/tenant (if applicable), and the Project Manager;
- compilation, assessment and integration of any additional data or information; and
- Initial Testing (Phase II) investigation team, with alternates identified for key personnel.
- After approval by the Project Manager, complete the sampling and analytical program. Prepare a report describing the program results, including a discussion of contaminated zones, the potential for contaminant migration, and effects of off-site contamination.
- The field work undertaken during the investigations in paragraph 1 of the present section shall be aimed at:
- determining whether surface contamination is present in excess of (CCME) applicable guidelines or any other guidelines identified by the Project Manager by taking surface water and sediment samples from bodies of water in the immediate vicinity of the site (e.g. ponds, rivers, creeks, lakes or other runoff areas);
- determining whether subsurface contamination is present in excess of (CCME, provincial) applicable guidelines by taking subsurface soil and groundwater samples from the areas of potential environmental concern previously identified;
- gathering general information about the site, such as:
- soil characteristics;
- subsurface geology;
- site hydrogeology;
- surficial drainage patterns;
- location of nearest structures and down gradient monitoring and drinking water wells;
- probable source(s) of contamination; and
- other relevant topographical information.
- establishing background levels of contamination at sites where on-site contaminant levels exceed (CCME) applicable guidelines or any other applicable guidelines identified by the Project Manager; and
- developing a preliminary conceptual model identifying potential contaminants, exposure pathways and potential receptors of concern.
- The report shall state whether (a) no further investigation is required, or (b) a Detailed Testing Program is warranted. Where the potential for site contamination is indicated by available site information, the report shall describe (a) the contaminant types, and the sources and extent of contamination, and (b) the areas, media and receptors of concern that must be addressed in a Detailed Testing Program or a Risk Assessment.
- Sample location, topographical, hydrogeological gradient, and existing site layout plans included in the report shall be provided in electronic data format (or format specified by the Project Manager). Final reports shall be submitted in hard copy ([number of copies to be specified by Project Manager]) and electronic form (WordPerfect and/or Microsoft Word formats), including electronic data copies of all tables and other data as specified by the Project Manager.
- Refer any queries about the project from the public, news media or others to the Project Manager.
- The Project Manager shall be notified immediately of conditions that pose an imminent threat to human health and the environment.
- Analysis of data will be in relation to agreed CCME guidelines or other guidelines identified by the Project Manager.
- If remediation is required, determine and evaluate remedial action alternatives, based on the following parameters:
- effectiveness in meeting CCME or other criteria as appropriate;
- cost (broken down by major activity and type/capacity of equipment required);
- safety procedures to be followed during remediation;
- monitoring requirements and costs;
- reduction of risk as appropriate to site location, site land use(s), and human health and/or ecological receptors;
- commercial utilization of proposed technologies, preferably in regard to the geographic area;
- compliance of the processes with applicable environmental standards;
- acceptability of processes to involved regulatory agencies;
- time frame for completion;
- the degree of commercialization of the technology and competition expected in remediation contract bids; and
- costs, including engineering overhead and all foreseeable uncertainties and contingencies.

A bidders' conference will be held at [location] on [date, time] to communicate the requirements of the contract and address any concerns of the interested contractors. At the conference, contractors will be given access to the following information:
- [Name of organization] policy documents;
- available site drawings; and
- previous environmental reports such as Environmental Baseline Studies (EBS) and environmental assessment or audit reports for the property.
[Where possible, the Project Manager will make hard copies of the relevant information or provide the contractors with the information on computer disc. For information that will not be copied (i.e. baseline studies), a schedule will be developed to permit contractors to view these documents].
- 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, where possible, 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].

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].
