Evaluation is in three phases:

Phase I – Initial screening: administrative verification through the CSD (business registration, directors, bank account, state employment status, tender default status) and checking of returnable documents (SARS PIN, municipal account, MBD forms, teaming agreements for JVs).

Phase II – Technical/functionality evaluation: bids are scored against the criteria in the terms of reference; bidders must submit supporting documentation for all technical requirements. Bidders do not rate themselves; the Bid Evaluation Committee scores. Any bid failing the minimum functionality score is disqualified and its financial proposal is not considered.

Phase III – Price and specific goals: prices must be in South African Rand. Points are awarded for price and specific goals as per MBD 6.1. Evidence for specific goals includes CK document, CSD report, ID documents of owners, MV force number, municipal account/lease agreement, and proof of disability if claimed.

ERWAT reserves the right to verify all submitted evidence and to negotiate rates.

For joint ventures/consortia, specific goal points are calculated as the average of the parties' ownership percentages, limited to the maximum available points.

The contract may be awarded to one to four service providers, at ERWAT's discretion.

The Bid Evaluation Committee (BEC) shortlists and evaluates bids in phases: pre-compliance screening, then functionality evaluation (if applicable), then price and specific goals. Bidders are scored on points for price and specific goals as per MBD 6.1. Total bid evaluation points are calculated to two decimal places, bids are ranked from highest to lowest, and the highest-scoring bidder(s) are recommended for award unless there are compelling reasons not to. ERWAT may appoint one to four service providers.
