  8. Parties to a contract • Employer • Engineer • Engineer is the person named in the contract data (or any other person appointed by the Employer and notified to the contractor) who is responsible for administering and supervising the execution of the work. Such person may be an engineer, architect, or any other technical person.

  17. Main functions of the Engineer -(continued …) • Determinations • Whenever the contract Conditions provide that the Engineer shall proceed in accordance with the Sub-Clause to agree or determine any matter, the Engineer shall consult with each Party in an endeavor to reach agreement. If agreement is not achieved, the Engineer shall make a fair determination in accordance with the Contract, taking due regard of all relevant circumstance.

  18. Main functions of the Engineer -(continued …) • Instructions of the Engineer • The Engineer may issue to the Contractor (at any time) instructions, which may be necessary for the execution of the Works and the remedying of any defects, all in accordance with the contract. The Contractor shall only take instructions from the Engineer, or from an assistant to whom the appropriate authority has been delegated. If an instruction constitutes a Variation, Clause related to Variations and Adjustments shall apply. • The Contractor shall comply with the instructions given by the Engineer or delegated assistant, on any matter related to the Contract.

  19. Main functions of the Engineer -(continued …) Engineer’s Impartiality • Wherever, under the Contract, the Engineer is required to exercise his discretion by : • giving his decision, opinion or consent, • expressing his satisfaction or approval, • determining value, or • otherwise taking action which may affect the rights and obligations of the Employer or the Contractor.

Any such decision,, opinion, consent, expression of satisfaction, or approval, determination of value or action may be opened up, reviewed or revised as provided in Clauses for Claims, Disputes and Arbitration

  20. Delegation by the Engineer • The Engineer may from time to time assign duties and delegate authority to assistant, and may also revoke such assignment or delegation. These assistant may include a resident engineer, and / or independent inspectors appointed to inspect and / or test items of Plant and /or Materials.

Any approval, check, certificate, consent examination, inspection, instruction, notice, proposal, request, test, or similar act by an assistant, in accordance with the delegation, shall have the same effect as though the act had been an act of the Engineer. However: • any failure to disapprove any work, Plant or Materials shall not constitute approval, and shall therefore not prejudice the right of the Engineer to reject the work, Plant or Materials • if the Contractor questions any determination or instruction of an assistant, the Contractor may refer the matter to the Engineer, who shall promptly confirm, reverse or vary the determination or instruction.

  22. Authorities not delegated by engineer (in NWSDB) • Approving variations • Granting time extensions • Certifying completion • Determinations • Taking over

  23. Summary • As you would realize now you / me have a significant role to play in the NWSDB contract management • In performing the delegated functions of the Engineer to you / me to achieve contract targets, one essential requirement is to: • Organize our selves / sites such that it ensures efficient coordination with all parties • Have an effective communication / record keeping system

  24. Site organisation • It is the duty of all involved in the contract management to work collectively towards the completion of the work within the programmed time, at scheduled cost while meeting the set quality standards. To meet these targets appropriate site organisation which ensures efficient coordination and effective communication with all parties in the contract and proper record keeping system is essential.

  25. Pre mobilization meeting – A useful tool in site organization • It is very much useful to have a pre-mobilization meeting with the contractor to determine the appropriate site organisation. Agreement with regard to procedures, methodologies, time frames for submittals, compulsory record keeping etc in the execution of work (in keeping to the requirements of the contract) should be reached at this meeting. To have a successful pre contract meeting it is essential to be well conversant with contents of all components of the contract.

  26. Site organisation structure Engineer’s staff • In determining the Organisation Structure there is no hard and fast rule to apply. However organization should essentially be structured such that each officer’s accountability is maintained. Consideration shall be given among others to: • Contractors organization structure • Locality of sites and nature of works to be performed Once the organization structure is decided it has to be formally informed to the contractor with; • Designations and names of individuals • Defined authority and responsibility levels • Channels of communications ; to avoid contractual disputes.

  27. Site organization structure contractor’s staff • The Contractor shall appoint the Contractor’s Representative and shall give him all authority necessary to act on the Contractor’s behalf under the Contract. • Unless the Contractor’s Representative is named in the Contract, the Contractor shall, prior to the Commencement Date, submit to the Engineer for consent the name and particulars of the person the Contractor proposes to appoint as Contractor’s Representative. • The Contractor shall not, without the prior consent of the Engineer, revoke the appointment of the Contractor’s Representative or appoint a replacement. • The Contractor’s Representative shall, on behalf of the Contractor, receive instructions under Sub-Clause Instruction of the Engineer.

  28. Site physical organisation • It is the duty of the Employer to duly provide the right of access and possession of all parts of the site to the contractor. Contractor is at liberty to physically arrange the site with plant and machinery as he wishes, to suit the construction in hand. However the site organization should comply to the requirements for Safety procedures, contractors operation on site and access roads. Our site offices shall be located considering the contractors site arrangement and any other factors as sensibly appropriate.

  37. Law and Language • The Contracts are governed by the laws of Democratic Socialist Republic of Sir Lanka and the language for all purposed for the Contracts are English (Normally).

  38. Recommended modes of communication • Log entries • Letters • Construction Programmes • Method statements • Meetings with minutes • Amendments / revised drawing

  39. Potential areas of contractual disputes • Time • Extension of time for completion • Suspension of work (These are almost always associated with cost implications, LD / OH, idle claims, PE) • Quality • Substandard work (This too is in most cases associated with cost implications) • Cost • Contractual claims (Over head claims, Idle claims, loss of profit, price escalation, change of legislation etc) • Valuation (SSR, substantial variation in BOQ quantities)

  40. Extension of time The Contractor shall be entitled to an extension of the Time for Completion if • a Variation (unless an adjustment to the Time for Completion has been agreed under Sub-Clause for variation Procedure) or other substantial change in the quantity of an item of work included in the Contract; • a cause of delay giving an entitlement to extension of time under a Sub-Clause of the Conditions of contract. (Ex. Unforeseen adverse physical conditions) • exceptionally adverse climatic conditions. • Unforeseeable shortages in the availability of personnel or Goods caused by epidemic or governmental actions; or • Any delay, impediment or prevention caused by or attributable to the Employer, the Employer’s Personnel, or the Employer’s other contractor on the site. If the Contractor considers himself to be entitled to an extension of the Time for Completion, the Contractor shall give notice to the Engineer in accordance with relevant Sub Clause. When determining each extension of time, the Engineer shall review previous determinations and may increase, but shall not decrease, the total extension of time.

  41. Suspension of Work • The Engineer may at any time instruct the Contractor to suspend progress of part or all of the Works. During such suspension, the Contractor shall protect, store and secure such part or the Works against any deterioration, loss or damage. • The Engineer may also inform the cause for the suspension. If and to the extent that the cause is notified and is the responsibility of the Contractor, the following Sub-Clauses shall not apply.

  42. Consequences of Suspension If the Contractor suffers delay and/or incurs Cost from complying with the Engineers instructions under Sub-Clause Suspension of Work and/or from resuming the Suspended work, the Contractor shall give notice to the Engineer and shall be entitled to : • an extension of time for any such delay, if completion is or will be delayed, • payment of any such Cost, which shall be included in the Contract Price. • After receiving this notice, the Engineer shall proceed in accordance with Sub-Clause for Determinations to agree or determine these matters. • The Contractor shall not be entitled to an extension of time for, or to payment of the Cost incurred in, making good the consequences for the Contractor’s faulty design, workmanship or materials, or of the Contractor’s failure to protect, store or secure in accordance with relevant Sub-Clauses.

  43. Quality and Cost disputes • Similar to the case of time related disputes (as we discussed in the previous two slides), terms of contract (Conditions) provide procedure for dealing in situations with quality and cost related disputes.

  44. Necessity of proper site record keeping • One essential requirement to manage the contract as a whole and specifically to manage the contractual disputes is appropriate site record keeping.
