12. C. Sequences of bid evaluation
Preliminary examination
The purpose of preliminary examination is to eliminate any
bid from further and more complicated consideration if they
don't meet the minimum standard of acceptability – not
substantially responsive
12

13. C. Sequences of bid evaluation
Preliminary examination
Verification: Bids should be properly signed, sealed, valid,
Eligibility requirement;
Acceptable bid securities;
Bid should contain all required documents;
Changes should be initialed;
Bids should be complete;
The above are checks for substantial responsiveness. Bids
should not be rejected on trivial /minor deviations or
procedural ground.
13

14. C. Sequences of bid evaluation
Preliminary examination cont…
Examples of minor deviations
Failure to initial on few pages of supporting information;
Submitting less copies of BDs;
Not using the form supplied, but furnishing the required
information;
Missing of attaching existing documentations (without giving
any benefit to the bidder & without prejudice to the interest
of other bidders);
…etc
14

15. C. Sequences of bid evaluation
Preliminary examination cont…
Examples of Major deviations
Stipulating price adjustment in fixed price tenders
Proposing a different design or product that does not offer
equivalent performance/not meeting specifications
Programming of contract start-up, delivery, installation, or
construction that does not comply with required times
Subcontracting in a significantly different quantity or
method than that allowed
Declining to take vital responsibilities and liabilities, e.g.
performance guarantees and insurance coverage
Taking exception to critical provisions e.g. applicable law,
taxes and duties, and dispute resolution procedures; etc…
15

16. C. Sequences of bid evaluation
Determination of bid responsiveness
A substantially responsive Bid is one, which conforms to all the
terms, conditions, and specifications of the bidding
documents, without material deviation or reservation. A
material deviation or reservation is one ;
 (a) which affects in any substantial way the scope, quality, or
performance of the Works;
 (b) which limits in any substantial way, inconsistent with the
bidding documents, the Employer’s rights or the Bidder’s
obligations under the Contract; or
 (c) whose rectification would affect unfairly the competitive
position of other bidders presenting substantially responsive
bids

Application of qualification/evaluation criteria
Strictly apply only the evaluation and qualification criteria
specified in the BD;
In the case of Post qualification of bidders, the criteria for
post qualification should be clearly set out in the BD;
If the lowest evaluated bidder fails to meet minimum
qualification requirements, the bid is rejected and the next
lowest evaluated bidder is subject to post qualification. (in
case of one envelope system). Otherwise; will be rejected
before opening of the financial bid

30

31. 8. Questions for discussions
1. A bidder has arrived a minute after
the deadline for submission. Will the
bid be accepted?
2. The bidders bid validity period has
been found 2 days short of the
specified 120 days. Is it minor or
major deviation?
31

32. 9. Questions for discussions
3. In ICB bid, A bidder has not submitted
Renewed license. Will it be reason for
rejection? Why?
4. After bids were submitted, A bid
opening was postponed due to
unavailability of majority of the tender
committee. Is there any problem with
this? why
32

33. Questions for discussions
5. The bidder has forgotten to include his
renewed trade license in his bid:
1. Is it minor or major deviation?
2. The bidder was requested to submit the
missed document and submitted the
license which has been renewed after the
dead line for bid submission. Will you
reject the bidders bid?
33

34. Questions for discussions
6. List some of examples of major
deviations in bids;
7. A bidder has written in his bid the
following: “We would like an increase
in the amount of mobilization
advance”. Can this be considered as
deviation?
34

35. Questions for discussions
8. A bid document was found that the bidding
form was not signed, but the bidder’s
stamp is there. Is it material deviation?
9. The client has varied the quantity of items
to be purchase by more than 15% during
award. What technical & procedural
problems does this involve?
35

36. 10.Cases for discussions
Cases 1:
During the bid evaluation of an ICB major works contract ( in which
only 4 bidders were shortlisted through prequalification process and
only 2 submitted their bids), a major unbalanced rate to one work
item was discovered in the bid of the lowest bidder. The procuring
entity has requested the bidder for clarifications and breakdowns of
the very exaggerated rate. The bidder had submitted his breakdowns
and during reviewing the submitted breakdowns, the client learned
that the bidder has made mistakes in the unit of measurement of the
work item whose rate was exaggerated. Correcting the unit of
measurement from LM to CM , as it is in the BD, would reduce the
price offered by about USD 6 Million. The client has made no change
to the breakdown except the unit of measurement and considered
this as “correction of arithmetic errors discovered by the client during
the evaluation of the bids, in accordance with ITB clause 31”. And
recommended the award with the corrected Price.
 Is this arithmetic corrections?
 Is the process fair, transparent, and acceptable??
36

37. Cases 2
EXCEPTIONALLY LOW BID
The six low bids for a road civil works contract have produced the following results after
evaluation: €
Bid A (Foreign) 4,880,243
Bid B (Local) 6,547,576
Bid C (JV Foreign) 6,841,782
Bid D (Local) 7,449,621
Bid E (JV Foreign/Local) 7,810,934
Bid F (Foreign) 8,075,122
The Employer’s estimate was €6,650,000. All of the above firms were pre-qualified.
If the lending institution financing this project required the contract to be awarded to the
bidder who was the “lowest evaluated, and met the appropriate standards of capability and
financial responsibility” it would appear that Firm A should be awarded the contract.
Questions:
(a) On the basis of the information above, what possible objections would you raise to
an award to Firm A?
(b) If Firm A is awarded the contract, should the Performance Security be increased
above the stated 10%?
37

38. CASE NO. 3
38
QUALIFIED BID
The following conforming bids are received on a construction project:
A €m98 B €m100 C €m102
The bid validity period is 90 days.
B offers a price reduction of 5% (i.e. a bid of €95 million) if the bid evaluation can be
completed and the notification of award made within 60 days, because he is already
mobilized on a nearby site with construction nearing completion, and has his labor force
waiting.
Question 1:
Can the Employer consider B’s alternative offer?
Question 2:
What if (A) had made a similar offer?

39. CASE NO 4: QUANTIFIABLE QUALIFICATION
Bids were received on a works contract in a remote area. The bidding documents stated: “There is a
Class 3 public road providing access to the site.” [Road transport regulations in the country stated that
Class 3 roads were designed to carry 10 ton axle loading.]
The low bidder, in the amount of €100M, qualified his bid as follows: “My bid is based on the assumption
that the State or Employer, in order to provide access to the site, will strengthen any weak bridges as
necessary to carry my heavy equipment, which has maximum axle loading of 10 tons.”
One other bidder made a similar qualification; the remaining six bidders had no comment on access.
A quantification of the qualification, i.e. for the Employer to arrange for repair of the bridges, amounts to
€3 million, bringing the low bidder’s evaluated price to €103 million. The next low bidder (without
qualification) is €110 million.
Although originally designed for 10 ton axle loading, some bridges were now in poor condition. The
timing of the repair work might place the Employer at risk regarding claims from the Contractor for delay
in mobilization.
The Employer is faced with a number of alternatives:
1) ask the bidder to withdraw his qualification without any change in bid price;
2) reject the bid as non responsive (i.e. containing a material deviation) and award the contract to
the next low bidder at €110m;
3) accept the qualified bid in the amount of €100m (since it is the lowest evaluated at €103m), then
arrange for repair of the bridges himself, and risk claims from the Contractor subsequently for
delay;
4) accept the qualified bid in the amount of €100m, then issue an extra works order after award of
contract for the contractor to do the work, or
5)somehow, without infringing the Rules, or the bidding conditions, or being unfair to other bidders,
shift the responsibility for bridge repair to the Bidder/Contractor before award of contract, albeit at
increased cost.
Question:
How would you proceed as Employer?
39

40. Exercise
Subsequent to ERA invitation to participate for ICB project of Azezo-Metema road
project three bidders have submitted their bid. During bid opening, it has been
noted that the JV of Bidder A-K has offered ETB 101 million while Bidder B offered
ETB 102 Million and Bidder C offered ETB 94.5 Million. The tender document of the
subject project specifies that domestic preference of 7.5% is applicable. There is no
arithmetic error and all bidders fulfill the qualification requirement. Detail of the
bidders is as shown below.
The JV of Bidder A-k is joint venture partner of local firm (wholly owned by
locals and the firm is registered in Ethiopia) and foreign Firm (wholly owned by
foreigners and the firm is registered outside Ethiopia) with 70 % local to 30 %
foreign share, it has quoted in one foreign and local currency and the quoted
exchange rate is for 28 days prior to the bid submission.
Bidder B is a local firm wholly owned by locals, registered in Ethiopia and
quoted in ETB.
Bidder C is entirely owned by Chinese, it has quoted in two foreign and local
currencies and the quoted exchange rate is for 28 days prior to the bid
submission.
You are required to identify the least evaluated bidder? Why? Give short report on
the analysis.
