The financial offers for tenders which were not eliminated during the technical evaluation (i.e., those found to be technically compliant) will be evaluated. The Evaluation Committee will check that the financial offers contain no arithmetical errors as outlined in Clause 31. The financial evaluation will have to identify the best financial offer.
31. Correction of Arithmetical Errors 31.1 Admissible tenders will be checked for arithmetical errors by the Evaluation Committee.
Errors will be corrected as follows: (a) where there is a discrepancy between amounts in figures and in words, the amount in
words will prevail; (b) where there is a discrepancy between a unit price and the total amount derived from
the multiplication of the unit price and the quantity, the unit price as quoted will prevail.
31.2 The amount stated in the tender will be adjusted by the Evaluation Committee in the event
of error, and the tenderer will be bound by that adjusted amount. In this regard, the
Page 14
Evaluation Committee shall seek the prior approval of the Departmental Contracts Committee to communicate the revised price to the tenderer. If the tenderer does not accept the adjustment, his tender will be rejected and his tender guarantee forfeited.
31.3 When analysing the tender, the evaluation committee will determine the final tender price
after adjusting it on the basis of Clause 31.1. F. CONTRACT AWARD 32. Criteria for Award 32.1 The sole award criterion will be the price. The contract will be awarded to the cheapest
priced tender satisfying the administrative and technical criteria. 33. Right Of The Contracting Authority To Accept Or Reject Any Tender 33.1 The Contracting Authority reserves the right to accept or reject any tender and/or to cancel
the whole tender procedure and reject all tenders. The Contracting Authority reserves the right to initiate a new invitation to tender.
33.2 The Contracting Authority reserves the right to conclude the contract with the successful
tenderer within the limits of the funds available. It can decide to reduce the scope of the works or to ask for a discount from the cheapest compliant tenderer.
33.3 In the event of a tender procedure's cancellation, tenderers will be notified by the
Contracting Authority. If the tender procedure is cancelled before the outer envelope of any tender has been opened, the sealed envelopes will be returned, unopened, to the tenderers.
33.4 Cancellation may occur where:
(a) the tender procedure has been unsuccessful, namely where no qualitatively or financially worthwhile tender has been received or there has been no response at all;
(b) the economic or technical parameters of the project have been fundamentally altered;
(c) exceptional circumstances or force majeure render normal performance of the project impossible;
(d) all technically compliant tenders exceed the financial resources available; (e) there have been irregularities in the procedure, in particular where these have
prevented fair competition. In no circumstances will the Contracting Authority be liable for damages, whatever their nature (in particular damages for loss of profits) or relationship to the cancellation of a tender, even if the Contracting Authority has been advised of the possibility of damages. The publication of a contract notice does not commit the Contracting Authority to implement the programme or project announced.
34. Notification of Award, Contract Clarifications 34.1 Prior to the expiration of the period of validity of tenders, the Contracting Authority will
notify the successful tenderer, in writing, that his tender has been recommended for award by the General Contracts Committee, pending any appeal being lodged in terms of Part XIII of the Public Procurement Regulations (being reproduced in Volume 1, Section 6).
34.2 Unsuccessful bidders shall be notified with the outcome of the evaluation process, and will be
provided the following information: (i) the criteria for award; (ii) the name of the successful tenderer; (iii) the recommended price of the successful bidder; (iv) the reasons why the tenderer did not meet the technical specifications/notification that
the offer was not the cheapest (if applicable); (v) the deadline for filing a notice of objection (appeal); (vi) the deposit required if lodging an appeal. 34.3 The recommendations of the Departmental Contracts Committee shall be published on the
Notice Board of the Department of Contracts, and published online on the Department’s website, mitc.gov.mt.
Page 15
35. Contract Signing and Performance Guarantee 35.1 After the lapse of the appeals period, and pending that no objections have been received
and/or upheld, the successful tenderer may be invited to clarify certain contractual questions raised therein. Such clarification will be confined to issues that had no direct bearing on the choice of the successful tender. The outcome of any such clarifications will be set out in a Memorandum of Understanding, to be signed by both parties and incorporated into the contract.
35.2 Within 15 calendar days of receiving the contract (against acknowledgment of receipt) from
the Contracting Authority, the successful tenderer will sign and date the contract and return it to the Contracting Authority with the performance guarantee and the Financial Identification Form (if applicable). On signing of the contract by the Contracting Authority, the successful tenderer will become the Contractor and the contract will enter into force.
35.3 Before the Contracting Authority signs the contract with the successful tenderer, the
successful tenderer may be requested to provide the documentary proof or statements required to show that it does not fall into any of the exclusion situations listed in Clause 7 of the Tender Form (Volume 1, Section 2). The above mentioned documents must be submitted by every member of a Joint Venture/Consortium (if applicable).
35.4 If the selected tenderer fails to sign and return the contract, other required documentation,
and any guarantees required within the prescribed 15 calendar days, the Contracting Authority may consider the acceptance of the tender to be cancelled without prejudice to the Contracting Authority's right to seize the guarantee, claim compensation or pursue any other remedy in respect of such failure, and the successful tenderer will have no claim whatsoever on the Contracting Authority. The tenderer whose tender has been evaluated as [second cheapest/second most economically advantageous] may be recommended for award, and so on and so forth.
35.5 Only the signed contract will constitute an official commitment on the part of the
Contracting Authority, and activities may not begin until the contract has been signed by the Contracting Authority and the successful tenderer.
35.6 Tender guarantees (bid bonds) provided by tenderers who have not been selected shall be
released within 30 calendar days from the signing of the contract. The tender guarantee of the successful tenderer shall be released on the signing of the contract, and on submission of a valid performance guarantee.
35.7 The performance guarantee referred to in the General Conditions is set at 10% of the amount
of the contract and must be presented in the form specified in Volume 2, Section 4, to the tender document the performance guarantee shall be released within 30 days of the signing of the Final Statement of Account (Final Bill), unless the Special Conditions provide otherwise.
36. Commencement of Works (Order To Start Works) 36.1 Following the signing of the contract by both parties, the Supervisor will issue a written
notice of commencement of the works in accordance with the General Conditions, as specified by the Special Conditions.
36.2 The Contractor must inform the Contracting Authority's representative by return that he has
received the notice. G. MISCELLANEOUS 37. Ethics Clauses 37.1 Any attempt by a candidate or tenderer to obtain confidential information, enter into
unlawful agreements with competitors or influence the committee or the Contracting Authority during the process of examining, clarifying, evaluating and comparing tenders will lead to the rejection of his candidacy or tender and may result in administrative penalties.
37.2 Without the Contracting Authority's prior written authorisation, the Contractor and his staff
or any other company with which the Contractor is associated or linked may not, even on an
Page 16
ancillary or sub-contracting basis, supply other services, carry out works or supply equipment for the project. This prohibition also applies to any other programmes or projects that could, owing to the nature of the contract, give rise to a conflict of interest on the part of the Contractor.
37.3 When putting forward a candidacy or tender, the candidate or tenderer must declare that he
is affected by no potential conflict of interest, and that he has no particular link with other tenderers or parties involved in the project.
37.4 The Contractor must at all times act impartially and as a faithful adviser in accordance with
the code of conduct of his profession. He must refrain from making public statements about the project or services without the Contracting Authority's prior approval. He may not commit the Contracting Authority in any way without its prior written consent.
37.5 For the duration of the contract, the Contractor and his staff must respect human rights and
undertake not to offend the political, cultural and religious morals of Malta. 37.6 The Contractor may accept no payment connected with the contract other than that provided
for therein. The Contractor and his staff must not exercise any activity or receive any advantage inconsistent with their obligations to the Contracting Authority.
37.7 The Contractor and his staff are obliged to maintain professional secrecy for the entire
duration of the contract and after its completion. All reports and documents drawn up or received by the Contractor are confidential.
37.8 The contract governs the Parties' use of all reports and documents drawn up, received or
presented by them during the execution of the contract. 37.9 The Contractor shall refrain from any relationship likely to compromise his independence or
that of his staff. If the Contractor ceases to be independent, the Contracting Authority may, regardless of injury, terminate the contract without further notice and without the Contractor having any claim to compensation.
37.10 The tender(s) concerned will be rejected or the contract terminated if it emerges that the
award or execution of a contract has given rise to unusual commercial expenses. Such unusual commercial expenses are commissions not mentioned in the main contract or not stemming from a properly concluded contract referring to the main contract, commissions not paid in return for any actual and legitimate service, commissions remitted to a tax haven, commissions paid to a recipient who is not clearly identified or commissions paid to a company which has every appearance of being a front company.
38. Data Protection and Freedom of Information 38.1 Any personal data submitted in the framework of the procurement procedure and/or
subsequently included in the contract shall be processed pursuant to the Data Protection Act (2001). It shall be processed solely for the purposes of the performance, management and follow-up of the procurement procedure and/or subsequent contract by the Contracting Authority without prejudice to possible transmission to the bodies charged with a monitoring or inspection task in conformity with National and/or Community law.
38.2 The provisions of this contract are without prejudice to the obligations of the Contracting
Authority in terms of the Freedom of Information Act (Cap. 496 of the Laws of Malta). The Contracting Authority, prior to disclosure of any information to a third party in relations to any provisions of this contract which have not yet been made public, shall consult the contractor in accordance with the provisions of the said Act, pertinent subsidiary legislation and the Code of Practice issued pursuant to the Act. Such consultation shall in no way prejudice the obligations of the Contracting Authority in terms of the Act.
39. Gender Equality 39.1 In carrying out his/her obligations in pursuance of this contract, the tenderer shall ensure the
application of the principle of gender equality and shall thus ’inter alia’ refrain from discriminating on the grounds of gender, marital status or family responsibilities. Tenderers are to ensure that these principles are manifest in the organigram of the company where the principles aforementioned, including the selection criteria for access to all jobs or posts, at all levels of the occupation hierarchy are amply proven. In this document words importing
Page 17
one gender shall also include the other gender.

A 3.11 Surplus Material
Page 84
The Contractor shall cart away all material extracted from the site, as a result of the
excavation, from the site, in securely loaded and covered vehicles, taking care to prevent the spreading of mud and debris on the adjoining highways; and shall be disposed of in accordance with local regulations at approved and authorised tips. The Contractor shall take all the necessary steps to ensure that the external areas and access roads are left clean and tidy during all stages of the work. Materials are to be disposed of in such manner as to maximise re-cycling and re-use.
A 3.12 Topfill
Before beginning general excavation, break up existing road and pavement surfaces from the
area of excavation down to the level of fill. Keep separate from excavated loose material. A 3.13 Topsoil Not applicable. A 3.14 Soft Areas Soft areas which, in the opinion of the Supervisor, are unsuitable for bearing the overlying
construction and applied loadings, shall be removed to such depths and widths as are directed by the Supervisor, and the material excavated shall be removed from the Site. The excavation shall be back-filled with suitable properly compacted fill material as directed by the Supervisor.
A 3.15 Excavation The measurements of all excavations and subsequent disposal are those before excavating and
to any depth required. The increase in bulk and any extra excavation required for planking and strutting and formwork for concrete, are to be allowed for by the Contractor.
The Contractor is to allow in his rates for all double handling of excavated material and
wheeling and depositing spoil heaps as may be necessary. Excavations for foundations and other substructures will be in accordance with the Drawings
and requirements of the estimated bearing pressure of the ground. Bottoms of excavations shall be levelled and thoroughly cleaned of all dust and loose material.

excavation free from water which involves continuous pumping so as to withdraw water from the foundations of adjoining Sites.
BACKFILLING A 3.17 Underwater fill material Use backfill materials as specified in clause A2.01 unless instructed otherwise by the
Supervisor. Protect existing hard stone structures at all times against any mechanical damages and if
required carry out works by hand. Care shall also be taken whilst working around existing and newly laid pipes. Prepare backfill material around pipes in such a manner that allows for sufficient space for the
required minimum thickness of concrete surround to the pipes as shown in the drawings. A 3.18 Granular Sub-base Material Type 1 Any fill for sub-grade to footings and ground slabs shall be inert Type 1 as specified in clause
A2.02 unless instructed otherwise by the Supervisor. The material shall be transported, laid in 150mm layers and compacted by means of a steel-
wheeled vibrating roller with a minimum roll load of 55kN per metre width without drying out or segregation. Each layer shall be given a minimum of eight passes. Plate bearing tests shall be carried out according to DIN 18134 to establish compliance with the required elastic modulus of subgrade reaction. Plate bearing tests shall be carried out at the locations and at the frequency stipulated by the Supervisor. Testing in the dock head recessed area can be carried out with a drop weight dynamic plate bearing test indicating the equivalent static plate bearing test.
The sub-base shall be finally blinded with sand or crushed fine material to form a smooth level
surface, with a tolerance of +0/-22mm. For the sub-base material under foundations and slabs, the sub-base shall be compacted to not
less than 98% of the maximum dry density of the material as per BS 1377. A minimum value of Ev2 of 120 MN/m
2 and a maximum Ev2/Ev1 ratio of 2.2 shall be achieved over the Type 1 layer.
TRENCH EXCAVATION AND FILLING A 3.19 General Trench excavation shall be carried out in any material to the lines, levels, falls, etc. as
required. Trenches are to be formed by a machine that produces a clean-sided trench of the required foundation width. Final trimming shall be made as necessary by hand, to achieve a trench bottom that is scraped level and clean.
Page 86
A 3.20 Notification A minimum of 3 working days’ notice of when trenching Works are to be undertaken shall be
given to the Supervisor in order that inspection can be made. A 3.21 Trench Width All trenches shall be excavated to the minimum width necessary to permit proper laying and
jointing of pipes, cables, etc. A cavity of adequate size shall be excavated in the sides and bottom of trenches at each pipe or cable joint and sling position to allow ample working space for making a sound joint and to allow free withdrawal of slings without damage to the pipes or the cables.
A 3.22 Excess Trenching
Should there be any trenching in excess of that required for the Works, the Contractor shall at
his own expense make good the ground with material, approved and specified by the Supervisor.
Note that the reinstatement with lean-mix concrete or concrete of a higher grade may be
ordered. A 3.23 Timbering Trenches shall be properly and adequately timbered or otherwise revetted and maintained to
ensure their stability and the safety of the workmen. Where directed by the Supervisor, the Contractor is to leave any or all timbering in the
trenches. Any timber so left is to be measured and paid for at agreed rates providing that, in the opinion of the Supervisor, the necessity for leaving it is not due to careless workmanship.
A 3.24 Control of Water Trenches shall be kept free of water at all times by pumping or other means. A 3.25 Soft Material Any soft ground or loose rock in the bottom of trenches shall be cut out and along with any
inequalities in excavation, filled up with a sand bed or concrete blinding as appropriate to the requirement of the trench bottoming.
A 3.26 Refilling Trenches After pipe laying and testing, pipes and the remainder of the trench shall be refilled with
grade C15 concrete unless instructed otherwise by the Supervisor or specified in the drawings. Concrete close or below water level shall be grade C25 concrete with anti-washout admixture as specified.
A 3.27 Planking and Strutting The Contractor is to allow in his rates for excavation, all necessary planking and strutting. The
Contractor is at all times responsible for the safety of the excavations. He is to provide all necessary planking to ensure this. Should any damage result to the excavations or Works, the Contractor will be held entirely responsible for any necessary extra works required or needed by virtue of this, and such works will be entirely at his own expense.
A 3.28 Reinstatement of Excavation Prior to backfilling, all formwork and support timber shall be removed from the bottom of the
excavation. Support timber shall only be removed to a height consistent with preventing collapse of the excavation and shall be progressively withdrawn as filling proceeds.
Page 87
No formwork or support timber shall be abandoned by the excavation without the specific approval of the Supervisor. Filling and ramming shall be added to make the rock soft and cohesive.
All reinstated excavated material to foundations must be solidly tamped at every 250 mm
backfill. No voids are to be left in the filling and every effort should be made to return the maximum
volume of backfill into the excavation. The Contractor is to select material for backfilling, which is to be the best of the excavated
material, free from:
a) top soil, roots and other vegetable matter b) soil with high moisture content c) combustible or perishable material d) any material not capable of being satisfactorily compacted
The Contractor shall plug any pipes cut off at the perimeter of excavations with foundation
grade concrete rammed in to refusal (but not less than 300mm). PROTECTION A 3.29 Generally Provide general protection as specified in the General Requirements of Part 1. A 3.30 Sides of excavation In addition to the safety precautions previously mentioned, protect the side of excavations
from deterioration and ensure that there is no risk of soil falling into concrete placed within them.

D3 WORKMANSHIP D3.01 General
Set up and maintain an accurately ascertained site datum level on an established benchmark. Agree route, depth and drain gradient with Supervisor. Clearly mark out trench route; (and widths when known) including inspection chamber positions.
Excavate trenches as follows: a. Clear the site along the route of the excavations. b. Break up and remove surface paving, etc. If such surfaces are to be reinstated,
cut back to a neat edge to facilitate reinstatement. c. Programme the excavations so that there is always the shortest time period
possible between trenching and pipe laying. If unavoidable delays occur, protect the trench bottoms or leave a final layer for hand removal.
d. Excavate the trenches to the minimum practicable width but not less than 450mm or 1.5 times pipe diameter plus 250mm, whichever is the greater. Excavate by open cut methods unless otherwise approved. Trench sides to be vertical up to 300mm above top of pipe. Normally acceptable alternatives are described in MSA EN 1610.
e. Remove obstructions. f. Report any voids or live services g. Plug any disused drains h. Form a firm evenly graded trench bottom. i. Remove any soft or hard spots and replace with compacted granular material to
produce a consistent bearing. j. Protect the bottom (e.g. with suitable blinding on pipe bedding) or lay pipes
immediately. k. Enlarge the trench excavations for manhole construction.
Page 113
l. Keep excavations free from water. m. Keep excavations safe. Remove any trench support progressively as compaction
proceeds.
When laying pipes undertake checks as follows: a. Ensure that pipes are clean, straight, not deformed or damaged in any way and
with factory-applied coating or seals in good condition. b. Check trench bottom for correct gradient with sight rails and boning rod (or
suitable equipment). Trim if necessary. c. Lay pipes to correct line and level by means of boning rods of other suitable
methods. Do not lay more than one pipe in the same trench without approval, including those at different levels.
