1Accredited Checkerfor Temporary EarthRetaining Structures

(TERS)

6

Current Practice

Design PE performsdesign

QP reviews and evaluatesadequacy of design

Construction PE supervisesconstruction

QP reviewsinstrumentation readingsand conducts siteinspection for safeexcavation

7

TERS

Need for additional measures for TERS

• Uncertainties in ground conditions

• Excavation can impact surroundingproperties

• High risk - requires close monitoring

• Requires specialist knowledge andexperience

8

Proposed Requirements

< 4m depth PE performs design AC performs independentcheck

4m depth ormore

PE (Geotechnical)performs design

AC(TERS) performsindependent check

9

Proposed Requirements

PE (GEOTECHNICAL)

Registered by Professional Engineers Board

AC (TERS)

Registered by BCA Criteria

- PE (Geotechnical) with post-graduate degree and 5 years design/construction experience, OR - PE (Geotechnical) with 10 years design/construction experience

10

Proposed Requirements

• Owner/developer (not builder) shall appointAC for TERS

• Issuance of permit to commence TERSconstruction will be granted based on

the strength of the certification of theAC(TERS)

11

2Review of Accredited

Checker System

12

CURRENT AC SYSTEM

• AC plays a important role in final check tominimize risk of design errors

• BCA approves plan based on strength ofAC’s certification

• Crucial that AC’s independent checkis competently done with adequateresources

13

AC ORGANIZATIONS (ACO)

• ACOs required to have more staff/resources.ACOs are in better position to carry outAC checks

• Critical that complex and medium-sizedprojects should be checked by ACOsas they have highly experienced andsenior professionals

14

PROPOSALS ON ACOs

BCA intends to enhance AC System as follows:

a) Reduce prescribed limit of value of building worksfor individual ACs from $10 million to $3 million

b) Enhance prerequisite for ACO registration:

Current required: 1 AC, 2PEs & 2 engrs

Proposed required: 2 ACs, 2PEs & 2 engrs

15

AC SYSTEM REVIEW

Feedback sought from industry on other ways to enhance the current AC System to improve competence and quality in AC checks for structural safety

16

3Supervision of

Structural Works

17

Current Provisions

• Resident Engineer - No work experience required under current legislation

PROJECT COST (MILLION) MINIMUMQSS

Non-Landed Landed

$3 - $15 $6 - $30 1 COW

> $15 >$30 1 RE

18

Issues with QSS

• IES/ACES feedback - developments tend to provide only 1 QSS. This is inadequate and QP unable to fulfil supervision duty effectively

• Structural safety can be compromised due to inadequate resources for supervision

• Problems cited with 1 QSS

– No backup when QSS go on leave, NS, falls sick

– No backup for supervision of critical works for long periods e.g. 24 hours concreting, night beam launching or supervision of off-site works

Breakdown: 2004 Projects

Overall: 70% of all projects has minimum 1RE/COW

20

Supervision Team

• Inadequate QSS will compromise quality of supervision and undermine safety

• Study Visit: HK Supervision System. Elaborate requirements for QSS.

• Proposal: QP to appoint supervision team in order to have adequate resources for supervision

21

QP Supervision Team• Feedback sought from ACES / IES on adequate

numbers of QSS required for projects in the following categories.

Project Cost Minimum QSS forSupervision Team

< $30 million

$30 - $60 million

$60 - $90 million

> $90 million

22

RE’s Work Experience

• ACES/IES Feedback: Experience of RE important, especially in larger, more complex works with safety impact

• Work experience will therefore be required for RE

• Feedback sought from ACES / IES on number of years of experience an RE should have to perform effective supervision

23

Projects < $15 million

Development Project Cost

18 storeys high-rise $6.3 million

18 storeys high-rise $9.95 million

20 storeys high-rise $10 million

20 storeys high-rise $14 million

Yu Neng Primary School $13.8 million

Bendemeer Road School $11 million

24

Projects < $15 million

• Currently only 1 COW provided for projects under $15 million

• Proposal amend current provisions to as follows:

Project Cost Minimum QSS

$3 - $6 million 1 COW (no change)

$6 - $15 million 1 RE

25

Supervision by Builder

• Duty is implicit. Builder has to provide all resources required to build according to approved plans, including resources for supervision

• Proposal: Builder to submit supervision team to support permit application, and some details on how supervision will be performed at site

• Builder will be required to review his supervision team if his proposal appears grossly inadequate

26

Review of Procurement System

Lim Jue MengSenior Manager

Procurement Policies

27

Areas of Review

• Licensing of contractors

• Review of CRS– Raising financial requirements

– Raising safety requirements

• Price quality method (PQM)

28

Objectives

• Ensure safety – Builders are competent and able to fulfill

statutory duties under the BC Act and related legislation

• Enhance capability & enable longer term sustainability– need to nurture better performing firms that

can deliver quality and ensure safety

29

Framework of Licensing of Contractors

• Registration of Licensed Contractors comprises:– Licensed Building Contractors (LBC) – Licensed Specialist Contractors (LSC)

• Registration renewable on a periodic basis

30

Framework of Licensing of Contractors

• Designated specialist works:– Piling– Earth-Retaining and Ground Stabilisation– Soil Investigation and Instrumentation– Structural Steelworks– Pre-stressed Concrete– Precast Concrete Works– Structural Strengthening

31

Framework of Licensing of Contractors

• Criteria for Registration:– Experience and qualifications of personnel– Safety record– Pass examination (if needed)

32

Framework of Licensing of Contractors

• Application for Registration to identify:– Approved Person (AP)

• the key decision-maker who has full financial control of firm

– Technical Controller (TC)• the key decision-maker who controls

construction work on site• responsible for supervision and execution of

works

33

Framework of Licensing of Contractors

• For new construction firms – based on qualifications and experience of

AP and TC

• For existing construction firms– exemption clause being considered

34

Review of CRS

• Licensing as minimum eligibility

• Raising financial requirements

• Raising safety requirements

35

Licensing as Eligibility

For licensing of both building and specialist contractors :

• The higher grade firms will mostly not be affected (e.g. A & B grades in CW and L5 & L6 in CR workheads). The lowest grades will be affected unless they raise their personnel levels.

36

Raising Financial Requirements

• Currently CRS uses paid up capital or net-worth

• BCA will consider other financial indicators (current liquidity ratio, net profit margin, loans to subsidiaries, cashflow balance, debt to equity ratio) and/or credit rating by third party to rank firms

37

Raising Safety Requirements

• Currently only the A1 & A2 grades contractors must be certified under the OHSAS 18000.

• To extend OHSAS18000 requirement to B1 and B2 grades.

• C1 and C2 firms to have simplified safety management system with some key requirements of OHSAS 18000

38

Raising Safety Requirements

• Firms with warning letter from MOM (24 demerit points within a 12-month period) will be downgraded for a year

39

Price-Quality Method (PQM)

• Quality attributes are already allowed in public sector tenders

• PQM enhances the current system by formalizing quality assessment through a systematic methodology – Optimise value by awarding to the most

competent tenderer with the most economically attractive proposal

– Differentiate the better contractors from average ones

40

Price-Quality Method (PQM)

• Price and quality tender evaluation models are practised in UK, Australia, Hong Kong, New Zealand, Japan, France, EU

• Studied the HK and NZ models

41

Proposed PQM

• Score tenders according to pre-defined weightings for both price and quality attributes

• Uphold transparency and objectivity

• Price still higher weightage (60-80%)

42

Proposed PQM

• Quality attributes include: – Past and / or ongoing projects’ performance

(timeliness, quality (CONQUAS), safety, awards etc)

– Relevant track records & past experience with agency

– Project specific proposal (resources, method statement, programme, innovations, etc)

43

Proposed PQM

• Formula approach to combine price scores and quality scores– lowest price tender max price score, highest

quality tender max quality score – Tenderer with highest overall score would be

awarded the project

44

Feedback from Industry

• BCA seeks feedback from the industry on the above review by 28 Feb 2005
