TPOM-12 (0714)

3. Requirements on Third Parties working near the Gas Transmission Pipeline

3.1 Pre-work Consultation with SPPG a) The works owner and contractor shall inform SPPG in advance of their intention to work in

the vicinity of the GTP and submit NCE accordingly. Such works include excavation, piling, earthwork leveling, bore logging, trial holes, blasting, tunneling or any earth works. The proposed work with construction drawings and method of statements shall be given to SPPG to evaluate the impact of the works on the pipeline. This enables SPPG to advise on appropriate precautionary measures to be taken.

b) The works owner and contractor shall obtain the as-built drawings of GTP from SPPG.

They are required to incorporate the pipeline alignment co-ordinates into their construction drawings. Please note that the information in the as-built drawings should be treated as confidential. Do not disclose or forward them to others.

c) No works in the vicinity of GTP shall be carried out without prior consultation and written clearance from SPPG.

d) SPPG shall be kept informed of any changes to the proposed works. e) No permanent structures shall be designed and constructed above the GTP. However,

surface road over the pipeline without reducing the pipeline cover may be acceptable, subject to SPPG's concurrence.

3.2 Precautionary Measures during Works a) The works owner and contractor shall take all necessary precautions to prevent any

damages to the GTP during the construction stage. They shall inform SPPG before carrying out any excavation works near the pipeline and report all damages to the pipeline and its coating to SPPG. Repair shall be done immediately to prevent corrosion aggravation to the pipeline at the damage location and thus becoming a potential hazard.

b) If any earthwork is within 5m of the pipeline (or more when required), a competent

surveyor shall be engaged to peg the pipeline alignment and interpret the pipeline depth from the pipeline drawings. Pegging and marking shall be clear and prominent and remain as such for the duration of works. Trial holes to prove the location of the GTP shall be carried out and all trial holes shall only be done in the presence of SPPG officer. The contractor's competent personnel shall supervise the earthwork, monitoring closely the pipeline depth based on the surveyor's interpretation.

c) Only manual excavation is allowed within 1m of the pipeline and only hand excavation is allowed within 0.5m of the pipeline.

d) Under no circumstance shall the GTP be exposed without written consent of SPPG. GTP

shall only be exposed in the presence of SPPG Officer. If a GTP is exposed, the owner/contractor shall take the necessary measures to protect the pipe from any physical impact that may cause damage to the pipe and/or its coatings to the satisfaction of SPPG.

e) Do not shift or remove warning markers indicating the existence of the GTP at site without

SPPG’s approval. The contractor shall protect them from being damaged or tempered. In the event the warning markers are damaged, they shall be reported to SPPG and replaced immediately. Where necessary, additional temporary warning markers shall be installed to warn others of the presence of gas pipeline.

TPOM-12 (0714)

f) For blasting works, piling or any works that cause ground vibration, the peak particle

velocity (PPV) of ground shock generated by the blast shall be limited to 15mm/s measured at the pipeline. The PPV shall be monitored in real time. SPPG shall be notified once the PPV reaches 10mm/s.

g) For tunneling, shaft excavation and piling works, ground consolidation could occur due

to ground water losses resulting in surface settlement. This settlement can potentially induce excessive stress on the pipeline. The contractor shall conduct a risk assessment to assess the impact of tunneling on the surrounding area. To monitor the surface settlement, surface monitoring points shall be installed along the pipeline alignment at every 10m intervals for at least 100m pipe length from the tunnel or shaft. The settlement shall be regularly monitored while excavation or tunneling works are being carried out. A differential settlement of 20mm will require all parties involved to assess the ground consolidation and evaluate the need to implement measure to arrest the consolidation. A thorough stress analysis of the pipeline shall be done by competent persons recognised by SPPG if the differential settlement reaches 60mm. Depending on the findings of the analysis, measures shall be taken to relieve the pipeline from the stress.

h) For crossing and parallel laying of services to GTP, Table 1 shows the required

separation distance between the GTP and other services or structures. It should be noted that other authorities may have stricter or additional requirements on minimum separation distance between proposed building / structure and the pipeline than what is stated here. Services crossing the pipeline shall not be at the previous boring pit locations of the pipeline, the locations are to be advised by SPPG.

i) For major works that span over a long period of time, the owner and contractor shall hold

monthly meetings to update SPPG on the progress and any changes to their works. j) For any new development surrounding the GTP, the developer shall inform the property

owner on the location of the pipeline within their premises and draw up measures to prevent any possible damage to it. Pipeline within a fenced compound shall be accessible to SPPG for patrolling and any maintenance works as and when required.

PREVENTION OF DAMAGE TO PUB WATERMAIN

General

1. We would like to draw your attention to Section 57 of the Public Utilities Act whichstipulates a duty to enquire on water mains if any person wishes to carry out any work inthe vicinity of watermains. We wish to highlight that under Section 47A of the PublicUtilities Act, any person who, whether wilfully or otherwise, removes, destroys or damagesor causes or permits to be removed, destroyed or damaged, any watermains belonging toor under the management or control of the Board, shall be guilty of an offence and shall beliable on conviction to a fine not exceeding $40,000 or to imprisonment for a term notexceeding 3 months or to both; or if the watermains is 300mm or more in diameter, to afine not exceeding $200,000 or to imprisonment for a term not exceeding 3 years or toboth. For more information of the Public Utilities Act, please refer tohttp://statutes.agc.gov.sg/.

2. Before commencing any works in the vicinity of PUB watermains, the QP shallobtain Water Service Plan (WSP) which indicates the approximate position of thewatermains (i.e.potable water, NEWater, industrial water and raw water mains) in thevicinity of the development. Smaller submains and connection pipes (<100 mm diameter)to customers' premises/properties may not be included in the WSP. The QP is to determineand indicate the exact alignments and depths of the watermains, submains and connections,on site by means of trial holes using manual excavation especially near watermains beforecommencement of any work. The position and alignment of the watermains shall beindicated on the survey plan, and shown at site to allow easy identification of thewatermains in future after completion.

3. The QP shall design both the temporary and permanent works in such a way to ensurethat ground movements are kept to an absolute minimum. The employment of proven

techniques and good workmanship are important to minimize ground loss and in turnground movements.

4. The QP shall select and ensure the operation of construction equipment shall be in amanner such that vibration induced damage to the watermains is prevented.

5. The QP shall establish and inform PUB of the procedures and methods for allexcavation and other construction works within 10 meters radius of watermains to preventdamage to the watermains during the work.

6. Before commencement of works, the QP shall submit the detailed method statementand drawings for the construction works, details of the machinery/equipment used withanalyses / assessment to demonstrate that the construction method proposed is non-invasiveand will not cause any impact or damage to the watermains.

proposed to be used at the development site and in similar ground conditions to show that this vibration limit would not be exceeded on the existing watermains. 8. Ground Displacements - Ground displacements caused by construction or other activities shall be “zero”. If the QP's analysis shows that the ground displacement due to the construction or other activities exceeds “zero”, a further design check shall be undertaken to ensure that the construction or other activities will not induce any damage to the watermains. 9. Groundwater Drawdown - The groundwater drawdown shall not exceed 10 kPa in the vicinity of the watermains. 10. No heavy machinery or vehicles shall be located or driven over watermains. 11. Construction Impact Assessment Report (CIAR) - The QP shall carry out a construction impact assessment of the construction effects of the works on the watermains in the vicinity of the works and submit the report to PUB for records. The report shall include the following details:

(i) The ground conditions, geotechnical profiles and relevant borehole logs.

(ii) The proposed construction equipment and methods, and sequencing of construction.

(iii) Assessments on the use of the proposed construction equipment /methodology on

the existing watermains, vibrations, ground displacements and groundwater draw downs and how the impacts would be mitigated to meet requirements.

(iv) Vibration characteristics and attenuation for major construction

No heavy machinery or vehicles shall be located or driven over watermains.


Instrumentation and Monitoring Programme

14. The QP shall carry out an instrumentation and monitoring programme to monitor the surface and subsurface ground movements, vibrations, the variation of ground water table and pore pressures, and the displacement and distortion of watermains. 15. The QP shall include in the monitoring plan all watermains that in his/her view are likely to be affected by the works. 16. The QP shall submit full details of the proposed monitoring procedures and instrumentation to PUB for concurrence before commencing the works. 17. The QP’s method statement shall include the proposed monitoring intervals and all requirements imposed by PUB. 18. The QP shall review the safe limits of ground movements, vibration levels or other changes for ensuring the structural integrity and proper functioning of all watermains. The QP is to provide PUB with the new alert level and stop work level for each of the monitoring instrumentations that will be deployed at site. He/she shall provide comprehensive basis for the proposed safe limits. 19. The QP shall provide a recharge well at site to maintain existing ground water table so as to prevent ground subsidence. The QP is to provide the proposal for the recharge well, with the technical drawing and calculation, to PUB for approval. 20. The QP shall verify and certify by monitoring that construction works have not resulted in displacements or vibration levels that have or will cause damage to any watermains. As a minimum, the following are required to be carried out and the relevant details are to be submitted to PUB:

(i) Monitoring of the displacements or vibration levels of watermains or the adjacent ground from the construction works. (ii) Preparation of action plans for remedial action in the event that displacements or vibration levels exceed the design limitations or cause damage.

21. It shall be clearly understood that the submissions of the instrumentation monitoring results and reports to PUB are only for PUB’s information. The QP shall be fully responsible for the analysis and interpretation of all the readings and measurements and for taking all remedial measures where necessary. When abnormal readings or measurements are obtained, QP shall immediately investigate the causes of the abnormalities and take all necessary remedial measures. QP shall promptly inform PUB should such abnormalities be likely to affect the structural integrity of the watermains 22. Instrumentation monitoring regime consists of inclinometers, ground settlement markers, vibration meters, piezometers, strain gauges, rod extensometers, etc. shall be carried out by QP to check whether ground movements & vibration impacts are within allowable limits during the construction works. Records of the instrumentation monitoring regime shall be endorsed by the QP and properly maintained at the site, submitted to PUB or made available for inspection by PUB upon request.


23. QP shall monitor and review the instrumentation monitoring results twice daily during the construction work on each day. QP shall look out particularly for excessive ground movements that may cause damage to the watermains. The QP shall submit the instrumentation monitoring records to PUB at a frequency stipulated by PUB. QP shall highlight in his submission if there are any excessive ground movements monitored or any other abnormalities. 24. QP shall stop the works immediately if the instrumentation monitoring results exceed the allowable limits and inform PUB immediately before investigating whether the works have any impacts on the watermains. The QP shall submit his/her assessment of the impacts of the works on the watermains, including his proposed mitigating measures to address the excessive ground movement or any other abnormalities, to PUB for approval, before resuming the works. 25. It shall be clearly understood that the submissions of the instrumentation monitoring results and reports to PUB are only for PUB’s information. The QP shall be fully responsible for the analysis and interpretation of all the readings and measurements and for taking all remedial measures where necessary. When abnormal readings or measurements are obtained, QP shall immediately investigate the causes of the abnormalities and take all necessary remedial measures. QP shall promptly inform PUB should such abnormalities be likely to affect the structural integrity of the watermains Surveillance Cameras above Large Diameter Watermains (≥ 300mm Diameter)

26. Contractor shall provide web-based IP surveillance cameras to continuously monitor construction activities in the vicinity of the large diameter (≥ 300mm) watermains. The number of cameras to be provided shall be approved by PUB and shall be sufficient to cover at least 6 meters from the watermains. 27. The surveillance cameras must be able to capture still pictures and perform continuous video recording. 28. The contractor shall provide PUB with the Internet website address for centralized viewing of the still pictures and video recordings of the construction activities above PUB watermains captured by the surveillance cameras. 29.
