Managing Defects Liability of defects Notification Correction and acceptance of defects Commercial Management Different payment mechanisms under different options The Schedule of Cost Components The Shorter Schedule of Cost Components

3 Defect

4 Defect 11.2 (5) A Defect is A part of the works which is not in accordance with the Works Information A part of the works designed by the Contractor which is not in accordance with the applicable law or the Contractor’s design which the Project Manager has accepted.

5 Searching for and notifying defects
42.1 Until the defects date, the Supervisor may instruct the Contractor to search for a Defect. He gives his reason for the search with his instruction. Searching may include uncovering, dismantling, re-covering and re-erecting work, providing facilities, materials and samples for tests and inspections done by the Supervisor and doing tests and inspections which the Works Information does not require. 42.2 Until the defects date, the Supervisor notifies the Contractor of each Defect as soon as he finds it and the Contractor notifies the Supervisor of each Defect as soon as he finds it.

6 Correcting defects 43.1 The Contractor corrects a Defect whether or not the Supervisor notifies him of it. 43.2 The Contractor corrects a notified Defect before the end of the defect correction period. The defect correction period begins at Completion for Defects notified before Completion and when the Defect is notified for other Defects. 43.3 The Supervisor issues the Defects Certificate at the later of the defects date and the end of the last defect correction period. The Employer's rights in respect of a Defect which the Supervisor has not found or notified are not affected by the issue of the Defects Certificate. 43.4 The Project Manager arranges for the Employer to allow the Contractor access to and use of a part of the works which he has taken over if they are needed for correcting a Defect. In this case the defect correction period begins when the necessary access and use have been provided.

7 Accepting defects 44.1 The Contractor and the Project Manager may each propose to the other that the Works Information should be changed so that a Defect does not have to be corrected. 44.2 If the Contractor and the Project Manager are prepared to consider the change, the Contractor submits a quotation for reduced Prices or an earlier Completion Date or both to the Project Manager for acceptance. If the Project Manager accepts the quotation, he gives an instruction to change the Works Information, the Prices and the Completion Date accordingly.

8 Uncorrected defects 45.1 If the Contractor is given access in order to correct a notified Defect but he has not corrected it within its defect correction period, the Project Manager assesses the cost to the Employer of having the Defect corrected by other people and the Contractor pays this amount. The Works Information is treated as having been changed to accept the Defect. 45.2 If the Contractor is not given access in order to correct a notified Defect before the defects date, the Project Manager assesses the cost to the Contrac­tor of correcting the Defect and the Contractor pays this amount. The Works Information is treated as having been changed to accept the Defect.

9 Payment

10 Payment – Core Clauses Cl. 50.2 The amount due is
The Price for Work Done to Date, Plus other amounts to be paid to the Contractor less amounts to be paid by or retained from the Contractor

11 Payment – Core Clauses Cl If no programme is identified in the Contract Data, one quarter of the PWDD is retained in assessments of the amount due until the Contractor has submitted a first programme to the Project Manager for acceptance…

12 Option A – Lump sum with Activity Schedule
Clause 11.2 (27) The Price for Work Done to Date is the total of the Prices for Each group of completed activities and Each completed activity which is not in a group A completed activity is one which is without Defects which would either delay or be covered by immediately following work.

13 Example of activity schedule
Activity / Sub-Activity No. Activity / Sub-Activity Prices (HK$) 9.4 Temporary Flow Diversion for Drains and Sewers 9.4.1 Temporary drainage management plan $ 9.4.2 Completion of temporary flow diversion for the works 9.4.3 Removal of temporary of diversion for the works 9.5 Drainage Works 9.5.1 Construction of 225 mm diameter uPVC pipe, with concrete surround near On Tin Street by open trench method Trench excavation for pipelaying Construction of bedding and laying of pipe Reinstatement Connection to existing manhole

14 Example of Payment schedule
9.4 Temporary Flow Diversion for Drains and Sewers  9.4.1 Temporary drainage management plan 100.00% Acceptance of temporary drainage management plan for the works by DSD and the Project Manager 9.4.2 Completion of temporary flow diversion for the works  Completion of temporary flow diversion for the works 9.4.3 Removal of temporary of diversion for the works  Completion of removal of temporary of diversion for the works 9.5 Drainage Works 9.5.1 Construction of 225 mm diameter uPVC pipe, with concrete surround near Gloucester Road by open trench method  Trench excavation for pipelaying  (1) 25.00% Completion of trench excavation to the proposed founding level for the first 20m (2) Completion of trench excavation to the proposed founding level for the second 20m (3) Completion of trench excavation to the proposed founding level for the third 20m (4) Completion of trench excavation to the proposed founding level for the remaining length in accordance with the Drawings

15 When do you get paid? 5m 20m but not yet reach founding level
No Payment on trench excavation 1st month 5m 2nd month No Payment on trench excavation 20m but not yet reach founding level 25% Payment of the Price entered for the pipe laying work 3rd month 22m and to founding level

16 Example of activity schedule (items to be inserted by contractor)
Black & Veatch 10 January 2013 Example of activity schedule (items to be inserted by contractor) Activity / Sub-Activity No. Activity / Sub-Activity Prices (HK$) 9.6 Testing and Commissioning 9.6.1 Closed Circuit Television (CCTV) Inspection of Pipelines $ Sub-total Price of Activity / Sub-Activity Nos. 9.1 to 9.6.1 9.7 Additional items required by the Contractor (to be inserted by the Contractor) e.g. Mobilization, Materials delivered to site, etc… Limit of Prices of Contractor inserted items is 10% of the total Prices of the Schedule

17 54 – The Activity Schedule
54.1 Information in the Activity Schedule is not Works Information or Site Information. 54.2 If the Contractor changes a planned method of working at his discretion so that the activities on the Activity Schedule do not relate to the operations on the Accepted Programme, he submits a revision of the Activity Schedule to the Project Manager for acceptance. A reason for not accepting a revision of the Activity Schedule is that it does not comply with the Accepted Programme, any changed Prices are not reasonably distributed between the activities or the total of the Prices is changed.

18 Option B – Lump sum with Remeasurement
Clause 11.2 (28) The Price for Work Done to Date is the total of The quantity of the work which the Contractor has completed for each item in the Bill of Quantities multiplied by the rate and A proportion of each lump sum which is the proportion of the work covered by the item which the Contractor has completed. Completed work is work without Defects which would either delay or be covered by immediately following work Clause 11.2 (31) The Prices are the lump sums and the amounts obtained by multiplying the rates by the quantities for the items in the Bill of Quantities.

19 55 – The Bill of Quantities
55.1 Information in the Bill of Quantities is not Works Information or Site Information.

20 How to be more advantageous in Option B Contract?

21 Payment in Options C & D

22 Option C & D : PWDD – Clause 11.2 (23), (25), (29)
Page - 22 April 12, 2010 PWDD Defined Cost +Payment to S/C + Cost Components in SoCC - Disallowed Cost Not justified by the accounts & records Should not have been paid to S/C Incur b/c C did not follow WI Incur b/c C did not give an E/W Correct Defects after Completion Correct Defects b/c C does not comply with a constraint Resources/ Plants/ Equip. not used to Provide the Works Preparation for and conduct of an adjudication Fee Cautious areas: - Scope and limit of Fee % - Status of MPF contribution - Pay after paid Etc…

23 Understanding Target Cost
Employer’s Share % 0% 50%

24 Clause 11.2 (29) - PWDD Original NEC3: HKSAR Amended NEC3
The Price for Work Done to Date is the total Defined Cost which the Project Manager forecasts will have been paid by the Contractor before the next assessment date plus the Fee. HKSAR Amended NEC3 The Price for Work Done to Date is the total Defined Cost which the Project Manager assesses the Contractor has paid before the assessment date plus the Fee.

25 Payment – Core Clauses Cl All the Contractor’s costs which are not included in the Defined Cost are treated as included in the Fee. Defined Cost includes only amounts calculated using rates and percentages stated in the Contract Data and other amount at open market or competitively tendered prices with deductions for a discounts, rebates and taxes which can be recovered.

26 Definition of Fee The Fee is the sum of the amounts calculated by applying the subcon­tracted fee percentage to the Defined Cost of subcontracted work and the direct fee percentage to the Defined Cost of other work. In HKSAR NEC form and NEC4, these 2 fee percentage have combined to be 1 fee percentage only.

27 Schedules of Cost Components
SoCC is like filing cabinet, or preamble for payment by cost Costs incurred in Working Areas Organizes different Defined Cost components into different categories so that QS can check if those are Defined Cost and payment can be assessed quickly All the expenses incurred in the Working Areas could be Defined Cost if that fits the description of SoCC All other expenses are covered by the Fee percentage

28 Page - 28 April 12, 2010 Open book accounting The Contractor shall open the account book for PM’s inspections to check expenditure incurred Subcontracting has to be carried out by prescribed procedures

29 RECORDS TO BE KEPT BY CONTRACTOR
