President’s Message “Out of the nine vacancies in the council, seven existing council members were re-elected together with two new elected members.”

Er. Koh Boon Liang President

ACES 41st AGM & Election This year AGM was held on the 22nd June 2012 at the Furama Riverfront Hotel. We were indeed glad to have a very large turnout and support from members for this annual event. Out of the nine vacancies in the council, seven existing council members were re-elected together with two new elected members.

The new council will continue to address major issues that are close to our hearts, such as matters in relation to the ever competitive nature of the business, the route towards greater productivity, the change to Eurocode and the investment into BIM technology.

Many more activities to support the industry on the above will be conducted for our members during the coming year.

The proposed amendments in the constitution was deferred and the new council will discuss further on another time to table the amendments.

BIM Moving forward, the mandatory BIM format e-submission for regulatory approval will be introduced by

Building and Construction Authority (BCA) in the phases: • From 1 July 2013, all architectural plans, starting with DC submissions, for new building projects more than 20,000 sqm • From 1 July 2014, all engineering plans for new building projects more than 20,000 sqm • From 1 July 2015, all plans for new building projects more than 5000 sqm To assist members in getting ready for BIM implementation by July 2014, ACES has in the pipeline, seminars on BIM awareness, BCA funding and hand-on workshops in the coming months.

Eurocode The Eurocodes signal a new beginning in the design of buildings and civil engineering structures. The Building and Construction Standards Committee (BCSC), with the support of the Building and Construction Authority (BCA) and other key partners started the development of SS based on the Eurocodes and UK National Annexes. This followed the announcement by BCA on 20

October 2006 to adopt Eurocodes in Singapore. A series of SS Eurocodes and National Annexes were subsequently published from 2008 onwards to facilitate the adoption of Eurocodes in Singapore. In line with this, ACES will be organising seminars on Eurocode – C&S and Geotechnical in coming months.

The recent Bugis Downtown Line (DTL) accident on 18 July 2012, where two workers were killed in a scaffolding collapse, again reminded us of the heavy responsibilities put on the shoulders of all stakeholders, we must constantly be vigilant in performing our role and duties together with stakeholders.

ACES will continue to support all our members so that collectively we are able to communicate with the various authorities and other stakeholders in the built environment to help make our business a sustainable and rewarding one.

and approved. There were interesting discussions on the proposed amendments to the Constitution, where opposing views were discussed at lengths. As no eminent resolution could be reached, the meeting agreed to delay this amendments to a later date.

This year saw 9 council members retiring from the Council, and new elections would have to be done to fill the vacancies. This year also saw the highest number of nominations, and many new faces stepping forward to serve. It was indeed encouraging and demonstrated that the consulting practice saw the need to engage

the industry with their participation and to elevate the status of the engineering profession.

There were a total of 14 nominations vying for 9 positions and each nominee is as strong as the other. The final 9 who were nominated are, and not in any order: 1. Koh Boon Liang 2. Loh Wah Kay 3.

LTA Academy - ACES Seminar

By Er. Ling Shiang Yun

F

ire in rail and road tunnels can be devastating and catastrophic. Because they are enclosed spaces, smoke and toxic gases can quickly spread along the tunnels making condition untenable for people trapped inside. Temperature in the tunnels can also rise very quickly due to rapid development of the fire and can cause extensive damage to the tunnel structures and installations resulting in prolonged closure of the tunnels for repairs and restoration.

On 10 July 2012, the LTAA-ACES seminar held at LTA auditorium drew the response of about 170 participants. This seminar has provided the participants with an overview of the fire protection system, and rail & road tunnels ventilation system.

1st speaker, Er. Yeo Swee Khiank (Sereca Fire Consulting Ltd) on the topic ‘Overview of Fire and Life Safety provisions in Road and Rail tunnel’. Er. Yeo presented his experiences on the fire protection system and the fire and life safety provision for rail and road tunnels to mitigate the risks and consequences of fire. The topics included road & tunnel exit provisions, fire incident detection system, fire suppression system, monitor and evacuations signage in tunnels and communication system.

2nd speaker, Er. Lim Lean Wan (LTA) on the topic ‘Ventilation of Road and Tunnel’. Er Lim gave an insight on the rail and road tunnels ventilation, fire incident management, smoke management system, and emergency exercise activities undertaken by LTA. The objectives are to provide safe and acceptable environment for road and tunnel users, and control smoke movement during emergency fire condition. The topic also covered Integrated Traffic and Plant Management System (ITPMS), road tunnel operation and response and recovery.

Participants found the topic interesting and very informative as the presentation were filled with practical illustrations.

3rd Dialogue session with

City Gas 28 March 2012

By Er. Callan Lam & Er. Yeow Mei Leng

T

he 3rd dialogue session with City Gas was held on 28 March 2012. Issues raised by ACES and City Gas/Power Gas/EMA responses were as follows:

A. Designated Representative’s consent ACES asked whether the Building’s Designated Representative (DR) or the building owner should issue the written consent if the building tenant was not the owner of the gas installation.

Power Gas pointed out that the responsible person for the gas installation to issue written consent could mean any person such as the building owner, the DR, the MCST or the main contractor of the project depending on whether the person had been empowered to be the responsible person or not.

EMA further confirmed that under the Gas (Supply) Regulations, the applicant has to obtain the consent from the responsible person so long as he or she has been empowered to be the responsible person to act for the gas installation owner.

City Gas reiterated that the applicant must obtain the consent from the responsible person prior to the commencement of gas service work if the applicant was not the owner of the gas installation to be connected to.

B. b. Procedures for Gas Turn On ACES put forward the current procedures to City Gas and Power Gas and suggested to streamline the whole process to enable easy submission of applications for gas supply and gas connection. ACES suggested to

combine the application forms for gas connection and gas supply in the handbook into one single form.

EMA stated that the procedures for admittance of gas and turn-on of gas supply were two different processes.

It was not advisable to combine both forms into a one common form. In addition, there are more than one gas retailers in the gas industry. Each gas retailer is required by the Gas Supply Code to establish and publish a Handbook on Gas Supply to provide a comprehensive guide to developers, consultants, professional engineers and licensed gas service workers in the application of gas supply.

City Gas added that the application for gas connection shall be made to gas transporter and application for gas supply to be submitted to gas retailer. Gas transporter and gas retailer were two different licensees. City Gas reiterated that the current forms were appropriate. It was not recommended to reduce the form for safety reasons.

C. c. Relocation of gas meters for HDB flats EMA replied that SCDF is the approving authority for the fire safety requirements, based on the circular issued by SCDF on 7 Jun 2011. The PE(Mechanical) would have to submit to SCDF a declaration form that the proposed meter location was in compliance with SCDF fire safety requirements and would notify City Gas before commencement of work. After completion of work, QP would request City Gas to turn on the gas supply to the premises.

Dialogue session with

Green Mark Task Force 11 June 2012

By Er. Callan Lam & Er. Yeow Mei Leng

A. ACES feedback Arising from the implementation of Green Mark version 4, the industry had been experiencing some compliance issues. These issues were collated and raised with the Green Mark Task Force Team in a meeting with BCA on 11 June 2012. The dialogue session was a fruitful one and through it all, BCA has replied and confirmed on certain requirements and practices that is helpful to our ACES’ members, please refer to the table below.

B. Baseline for small fan systems According to BCA, there will be no energy savings claims for small fan systems less than 4 kW under version 4. Excluding the small fans, projects like hotels with many small FCUs, the difference in the overall energy savings can be quite significant. After much deliberation, the taskforce agreed to adopt the baseline of 0.17kW/CMH for fan power less than 4kW; ducted fans with fan power less than 4kW will be studied further. The taskforce also confirmed that the total fan

system power only refers to the supply fan motor and does not include fresh air and exhaust fan power.

C. Nameplate power ACES’s feedback on the use of absorbed power instead of nameplate power for fan in the energy modelling.

There are many energy modelling software do not allow direct input of nameplate power for computation. BCA suggested two options for task force consideration: ASHRAE 90.1 Table: 6.5.3.1.1A Fan Power Limitation Option Constant Volume Option 1: kW ≤ L/Ss . 0.0017 Fan System Motor Nameplate kW Option 2: Input kWi ≤ L/Ss .

Fan System input KW 0.0015 + A

Variable Volume kW ≤ L/Ss . 0.0024 Input kWi ≤ L/Ss .

0.0021 + A

The taskforce agreed that Option 2 is acceptable as it will have a more stringent baseline and provide more flexibility with the use of absorbed power.

Green Mark Advisory Committee - Taskforce Meeting on Review of Gm Version 4.0 - Energy Efficiency Requirement Item ACES’ Descriptions ACES’ Feedbacks & Recommendations 1 BCA is not accepting the energy BCA to allow savings but basing on 0.17 w/cmh. savings for motors < 4kW, which they claim that there is no benchmark set in clause 14.2.1 SS553.

Fan power less than 4kW

1b

Fan power : Request clarification as to which systems 0.667 W/CMH as benchmark (variable flow) can be applied to for MV systems

BCA to review the energy savings % for developments served by district cooling plants. Currently for Platinum rating, developments on DCS plants have to prove energy savings of 33%. If the receptacle load for this development is high, which it usually is (as such buildings usually have data centres/banks/ IT companies as their tenants) the absence of the chiller plant in this equation is a penalty on the energy savings.

Taskforce’s Conclusion Use the baseline of 0.17W/CMH for all fan systems for fan power less than 4kW. In particular, if the fan efficiency is worse than 0.17W/CMH for the case of ducted FCU and AHUs, ‘negative’ saving will not be accounted for.

As above.

Why should the benchmark be 0.17 W/CMH – what is the basis for this? This sub 4kW fan issue is one of the biggest problems in the GM process at present but it is not appropriate to propose that the basis shall be 0.17 W/CMH for all. It may be possible for FCU systems (requires better definition) less than 4kW to adopt 0.17 W/CMH. There are many MV systems and AHU systems which fall into a category less than 0.4kW for which the real pressure requirements mean that a higher benchmark is required. Can BCA consider a higher benchmark like 0.22 W/CMH? There seems no basis why a variable flow MV To adopt only one baseline for constant system has a higher benchmark (for AC systems flow and variable flow/speed for MV fan, there is at least rational for this difference) i.e. 0.47 W/CMH. Any saving via CO sensor will be calculated and reflected under the criterion of Energy Efficient Features.

For buildings without chiller plant, the energy Saving of 33% exclude the consumption savings should be 30% or lower. At the moment, of chiller. If the receptacle load is high, for chilled water tapping from DCS plant, BCA the receptacle load will be capped at 25% requires 33% based on audit requirements. of the total building consumption with baseline chiller. BCA will include a clearer FAQ on website to explain this.

Currently regenerative lifts energy savings is capped at 18%, and no savings to be claimed for gearless lifts.

Currently for areas where the lighting power budgets are not defined in SS530, no savings could be claimed.

Hence not much “push” factor for the development to concentrate on the lighting power budget for such areas.

Currently the verification stage process is not too clear yet. The developer does not know when to call the auditors in to conduct the verification stage, what information to provide, how many months of data logging is required, when should the data logging commence, etc.

In the current practice, only the base building’s Mechanical and Electrical PEs are required to endorse on GM application although the documentation is prepared the GM consultant.

Taskforce’s Conclusion The saving cap of regenerative lift of 18% is on top of VVVF system and sleep mode. VVVF system and sleep mode will be able to claim 10% energy saving. If the regenerative have VVVF system and sleep mode as well, they will be able to claim a maximum of 18% + 10% = 28% energy saving. Assessors will also review on other innovative lift systems and saving on caseby-case basis.

For items not in the SS530, BCA assessors BCA should consider to come up with a list of lighting power budget for such typical areas that are willingly to accept other reasonable are not covered under SS530 (toilets, M&E plant baseline for reliable sources, such as rooms, kitchens, etc).

ASHRAE. BCA should clearly document and inform all projects on the requirements as part of the BCA Green Mark Certification Standard document.

BCA to insist that a qualified GMP to endorse on the GM application and submission in addition to the Base Building’s PE Endorsement. The base building’s PE should only be responsible for the M&E equipment and systems. The GMP is responsible for the computation, analysis , modelling , EEI and all other requirements for achieving the GM. BCA has been requested the The PE’s should have a responsibility to confirm Mechanical & Electrical PE’s to endorse the basis of the GM submission and calculation that building operational energy is consistent with the building design. The PE’s (specifically kW/RT for cooling systems) do not operate the building and have control of will meet specific targets. the usage and decisions made by the building operator, so such an endorsement is not appropriate to the PE’s responsibility.

Nameplate power in respect of energy modelling. In assessments, BCA is adopting nameplate power as the basis for fan and pump systems in energy models. Appendix B of the GM Certification Standard (V4) has contradictions in applying nameplate power to worked examples. BCA expresses that the use of nameplate power, rather than absorbed power, is a means to prevent overdesign. For a large fan or for a chilled water pump, the difference between the absorbed power and the next step in available motor size can be considerable, up to 40% and this is unreasonable in predicting energy usage.

The basis for the EEI Calculation described in Appendix E of the BCA GM Certification Standard for New Buildings includes a factor for vacancy rate (VCR) General changes to GM requirements and implementation. BCA has imposed requirements on developers which are not stated within the GM Certification Standard or other referred codes. For example energy savings associated with small fans. A number of features of the V4 requirements were also required to be adopted by V3 projects

BCA will draft up a clear guideline and make it available on website. It will also be reflected under FAQ.

To remain status quo due to 1. GMP may not have the capability to undertake the design.

2. PE will have take responsibility on the changes in design and proposal recommended by GMP.

BCA will publish verification guideline on website to help building owners to understand what is required during verification. Concerns will also be addressed under FAQ. Building owners need not engage the same PE that design for the building system to endorse on the building operational energy efficiency.

Propose that the methodology be revised to: Project team is allowed to use option 2 Use nameplate power for compliance with SS553 under ASHRAE 90.1 2007 Clause 6.5.3.1 and Table G3.1.2.9 which uses input power in terms of maximum power/flow for air side with better baseline for energy simulation. and water side systems (ie, cap the over design situation) -Use absorbed power for equipment (air side and water side) for energy simulations for the proposed building (which are compared against a reference benchmark which does not get penalised by ‘nameplate rating’)

This factor should be zero for new building modelling. It comes about historically where EEI figures are used as a benchmark for measuring the actual energy consumption of a building in use (where the EEI will be higher if a vacancy rate is applied).

Suggest that changes to the administration of GM projects need to be advised publically and then a stand down period (likely one year) be applied prior to the implementation of changes.

VCR to keep.

BCA will issue circulars in advance to reflect important decisions and critical changes.

BIM E-Submission in Singapore

By BCA,coordinated by Er. Lim Peng Hong

G

lobally, a common strategy adopted by governments to encourage BIM adoption in the industry is to set a deadline for mandatory use of BIM for projects of a certain size or complexity. For example, by 2016 it will be mandatory for the use of BIM in all UK government projects over £5 million.

Besides leveraging on the use of public procurement policy to drive BIM adoption, Singapore will capitalize on the use of the CORENET system, which is already embraced by the industry, to speed up the use of BIM. In January 2011, BIM e-Submissions were officially accepted for the architectural discipline; and also for the engineering disciplines in April 2011. Under BCA leadership, 12 regulatory agencies work together to allow BIM-ready Qualified Persons (QP) to submit their BIM for various aspects of regulatory approvals via the CORENET system. Singapore became the first country in the world to accept full BIM electronic submissions for regulatory approval, and starting from July 2013, BIM e-submissions will be mandatory for certain projects and disciplines.

To help industry professionals with BIM e-submission, a set of BIM e-submission guidelines and templates have been developed by CORENET participating agencies in 2010. They play an important role in standardizing the way BIM models are being prepared across the industry. This is similar to how

2D CAD standards (CP 83) had resulted when CORENET was first introduced in 2001. Such a standard helps to improve data sharing and collaboration among the project team members.

Leading to the mandatory dates, a series of monthly free workshops on BIM esubmissions have been arranged by the BCA’s Centre of Construction IT (CCIT) to train Qualified Persons (QPs) on the BIM e-submission

requirements. Hand-holding will also be provided to firms that are doing BIM e-submissions for the first time.

Besides getting QP firms ready to prepare BIM e-submissions, CCIT will also solicit feedback from the firms to refine the e-submission guidelines and templates. Together with the QP firms, CCIT also hopes to identify a set of BIM based software utilities that are useful to the QP in automating computations (e.g. Concrete Usage September 2012 • 9

T

his site visit held on 5 April 2012 was supported by National Parks with a total 32 participants. The three invited speakers were Er. Johnny Lim, Er. Russell Cole and Er. Thomas Cheang.

Er. Russell Cole’s presentation focused on the design of the biomes' shell structure. The two biomes were designed stimulating coolmoist or cool-dry environment housing a variety of plants from different climate regions. Er. Russell highlighted the role of Arup’s facade engineering in these enclosures, touching on forms, modulation studies, geometry resolution and typical glass and glazing systems. He also shared with the participants on how the shading devices contribute to the indoor climate control of the biomes for plants to strive and how the maintenance access was developed for this state of the art structure.

Er. Johnny Lim and Er. Thomas Cheang further shared with participants on the mechanical & electrical aspects of sustainable engineering technologies and design principles deployed in Gardens by the Bay Marina South such as the type of façade, slab cooling, shade control, liquid desiccant system, PV system, biomass and bio-diesel co-generation system.
