5. EVALUATION OF PROPOSALS
5.1. Completeness
IUCN will firstly check your Proposal for completeness. Incomplete Proposals will not be considered further.
5.2. Pre-Qualification Criteria
Only Proposals that meet all of the pre-qualification criteria will be evaluated.
5.3. Technical Evaluation
5.3.1. Scoring Method
Your Proposal will be assigned a score from 0 to 10 for each of the technical evaluation criteria, such that ‘0’ is low and ‘10’ is high.
5.3.2. Minimum Quality Thresholds
Proposals that receive a score of ‘0’ for any of the criteria will not be considered further.
5.3.3. Technical Score
Your score for each technical evaluation criterion will be multiplied with the respective relative weight (see Section 4.4) and these weighted scores added together to give your Proposal’s overall technical score.
5.4. Financial Evaluation and Financial Scores
The financial evaluation will be based upon the full total price you submit. Your Financial Proposal will receive a score calculated by dividing the lowest Financial Proposal that has passed the minimum quality thresholds (see Section 5.3.2) by the total price of your Financial Proposal.
Thus, for example, if your Financial Proposal is for a total of CHF 100 and the lowest Financial Proposal is CHF 80, you will receive a financial score of 80/100 = 80%
5.5. Total Score
Your Proposal’s total score will be calculated as the weighted sum of your technical score and your financial score.
The relative weights will be:
Technical: 70%
Financial: 30%
Thus, for example, if your technical score is 83% and your financial score is 77%, you will receive a total score of 83 * 70% + 77 * 30% = 58.1% + 23.1% = 81.2%.
Subject to the requirements in Sections 4 and 7, IUCN will award the contract to the bidder whose Proposal achieves the highest total score.

Proposals for Components of the Operational Water Allocation Model
Model Interface
The interface of the Revue sub-basin water allocation model should be visually
appealing, predominantly blue to symbolise ARA-Centro, IP and water, with a clearly
visible map of the Revue sub-basin, which may be depicted within the Buzi basin,
where the georeferenced locations of water users’ facilities within the sub-basin are
shown on the map using clearly defined symbols and their respective names, in
accordance with the functionalities of geographic information systems (GIS). In this
case, the system must be georeferenced.
The map should have features that can be manipulated in accordance with the
aforementioned programmes and others, allowing for visualisation at the level of sub
basins, water bodies, abstraction sources, and administrative divisions such as
villages, hamlets, towns and cities, with an indication of the number of users and the
number of beneficiaries where applicable. These names must be represented
graphically and descriptively (name and graphic) on the map, and may be represented
either by name and graphic, or by graphic alone, according to the user’s preference.
The interface should also include a legend for the points, symbols and other
designations appearing on the map, to provide clear guidance on what they represent.
Data on Water Demand
At a minimum, the model must contain the following features or information regarding
water demands:
• User data: full name of the individual or collective user; name of the
representative’s identification document (ID card, DIRE, passport or other);
identification document number;
• Type of Resource: It must contain three types of resources to be
abstracted, namely Surface Water from a River, Surface Water from a Lake
or Reservoir, and Groundwater;
• Location of the Abstraction: this section must include the georeferenced
location data of the abstraction source, for representation using a symbol
based on the type of activity. The abstraction location data should be
presented in a flexible format, in separate windows that allow for
modification and quick viewing, and which enable the selection of some or
all location items. Accordingly, the following designation is proposed for the
location information: Province, District, Administrative Centre, Town,
Neighbourhood, Avenue/Street;
• Water Uses: this component should be flexible to update and automatically
convert the Volume Captured into m³/month, m³/year, Mm³/month and
Mm³/year, etc.
Model Features
The model should allow for a statistical analysis of demand data, namely:
• Processing annual, monthly, quarterly and half-yearly average water
demand for the entire sub-basin for a single user or group of users, water
availability in the sub-basin over the same analysis period, and the
respective ecological flow, taking into account the time period analysed;
• Graphical representation of water demand data for the sub-basin as a
Terms of Reference for Consultancy v1 August 2025
whole, for a group of users, and for an individual user in relation to
availability and the ecological flow for a given period;
• Graphically represent the percentages or absolute and relative values of
the key indicators to be proposed by the consultant, which will enable
decision-making regarding water allocation, always cross-referencing
these with water availability in the sub-basin and the ecological flow.
• Simulate the impacts of water demand scenarios for a user or group of
users over short, medium and long-term periods in situations of water
surplus (floods) and water scarcity (droughts);
• Simulate and project water allocations for future projects in the basin and
water availability, as well as the ecological flow; and
• Allow the import and export of data and information in various formats
(vector, raster).
Applications of the Model
Scenario Development
Based on physiographic characteristics, hydrology, the occurrence of groundwater in
the sub-basin, and other assumptions, the model should develop short-, medium- and
long-term scenarios regarding the implications of water demand in the event of
occurrences such as droughts and floods. The scenarios should provide effective
results and corresponding indicators to enable water resource managers to make
decisions regarding water allocation processes. The quantitative results of the water
availability indicators in the scenarios to be presented should balance demand with
ecological flow and availability.
Types of Demand and Activities
The model must be capable of distinguishing between different types of water resources,
namely surface water and groundwater. Furthermore, it must also distinguish between the
types of water and demands, including water supply, hydroelectricity, mining, agriculture,
aquaculture, other industrial activities and tourism. In this regard, in order to ensure that the
classification of water users within the model and other key elements are accurate, the
supplier should consult all applicable legislation on this matter, with particular reference to
the Water Act, the Licensing and Concessions Regulations, the Regulations on the
Exploration and Exploitation of Groundwater, and the Regulations establishing the new
surface water charges, and may propose a more appropriate classification for this purpose.
Projects in the Pipeline
The Revue sub-basin is characterised by the existence of several projects in the
pipeline that will require water for their implementation. In this context, the tool must
be capable of producing simulations for the short, medium and long term.
In principle, ARA-Centro, IP will provide a list of known future projects, including their
location, purpose, and monthly and annual water demands, to be integrated into the model.
In addition to the current projects in the pipeline, the model should be designed to
accommodate future projects as they arise over time.
Updating Information
The model must be flexible, allowing for the updating of demand data, ordinarily every
three months and whenever necessary. The process of updating water demand data
will need to take the following factors into account:
• Users’ water demands change due to variations in production;
• Raw water users sometimes cease their activities and request the
cancellation of water uses and allocations; and
• The emergence of new requests for water use.
Terms of Reference for Consultancy v1 August 2025
At the start and during the preparation of the consultancy, the consultant should plan
to carry out campaigns for the inspection, registration and updating of water demands
throughout the Revúe sub-basin.
Model Users
The allocation model should incorporate access authorisation profiles for specific
activities within the model, namely:
• Registration – entry and analysis of information on water demands to
support water allocation recommendations;
• Groundwater Resources – entry and analysis of information on
groundwater;
• Surface Water Resources – entry and analysis of hydrological information
in the sub-basin;
• Head of the Water Resources Department – viewing of information for
analysis and to support the water allocation opinions received;
• Director General and Division Director – viewing of information
(indicators) for decision-making.
Thus, the registration unit will be responsible for the entry, processing and analysis of
information regarding requested water demands, availability in relation to the
ecological flow, possible usage scenarios and their respective impacts, and proposals
for authorisation to issue licences for water use and exploitation. The main indicators
proposed by the consultant will be analysed to determine whether to issue a favourable
or unfavourable opinion regarding the requested water demand. For each
authorisation, the flow rate to be pumped to the boreholes will be proposed in the case
of groundwater.
In the areas of land registration and groundwater resources, they will regularly carry
out simulations for water allocation. In the event of changes to water demand within
the sub-basin, they must report to the Head of Department, and where necessary to
the Director-General or Division Director, regarding the water situation and availability,
to facilitate strategic decision-making on water resource management.
The consultant shall also propose the best water allocation model, based on their
experience and the specific characteristics of the sub-basin.
Knowledge Transfer
In this context, the consultant shall ensure the training of seven (7) technicians from
ARA-Centro, IP throughout the data collection process, model design and calibration
at interim stages, as a means of knowledge transfer.
The knowledge transfer referred to here has nothing to do with training; therefore,
training must be provided in addition to the involvement of ARA-Centro, IP technicians
in the development of the models.
Data Analysis and Processing
A thorough analysis of the information collected and organised in the database will be
carried out and provided to the consultant for subsequent work on model development.
Whenever it is deemed necessary to collect information in the field, the technical team
from ARA-Centro, IP will be immediately available to support the process.
Model Licences and Warranties
The model must be covered by a warranty of at least one (1) year following calibration
and delivery to ARA-Centro, IP. During this period, should any issues arise relating to
functionality, the consultant must provide the necessary technical support at no
additional cost to the contracting entity.
The licence must be valid for installation on at least 5 user workstations and renewable
every 3 years, during which time the model will be maintained to keep pace with likely
Terms of Reference for Consultancy v1 August 2025
Terms of Reference for Consultancy v1 August 2025
technological developments through updates and to ensure compatibility with other
requirements.
Selection of the Model
The consultant must develop the model on a platform that does not require licence
maintenance costs.
Ownership Rights
All products generated as a result of the services provided by the contractor are the
property of ARA-Centro, IP, and any disclosure or commercialisation by the contractor
is prohibited.
Required Materials and Equipment
During the presentation phase of the Selected Model Prototype, based on the survey
conducted, the consultant must submit a proposal listing the equipment and materials
required to use the model, taking into account the anticipated capacity and users. This
equipment refers to computers and their peripherals, operating systems and
capabilities, as well as suitable equipment for the ongoing collection of data and
information (e.g. cameras, GPS, etc.) which will feed into the model during its
implementation.
