4.0        Noise Monitoring

4.1         Monitoring Parameters and Methodology

The construction noise level shall be measured in terms of A-weighted equivalent continuous sound pressure level (L_Aeq). L_{Aeq(30 mins.)} shall be used as the monitoring parameter for the time period between 0700-1900 hours on normal weekdays for each Noise Sensitive Receiver (NSR) weekly. As supplementary information for data auditing, statistical results such as L_A10(30mins)  and L_A90(30mins) shall also be obtained for reference at the same time during the monitoring measurement. For all other periods (including restricted hours), L_Aeq(5mins) shall be employed for comparison with the Noise Control Ordinance (NCO) criteria.

 

Noise measurements should not be made in the presence of fog, rain, wind with a steady speed exceeding 5m/s or wind with gusts exceeding 10m/s. The wind speed shall be checked with portable wind speed meter capable of measuring the wind speed in m/s.

 

The monitoring station shall normally be at a point 1m from the exterior of the sensitive receivers building façade and be at a position 1.2m above ground. If there is a problem with accessing to the normal monitoring position and without 1m from the exterior of the sensitive receivers building façade, a correction of +3dB(A) for the measurement shall be made to the measurement data and the description of the monitoring location will be classified as free field measurement data.

The following summaries good site practices and measures that should be followed:

 

w        Well-maintained plant should be operated on-site and plant should be checked regularly;

w        Plants (such as trucks, cranes) that may be in intermittent use should be shut down between work periods or should be throttled down to a minimum;

w        Plant known to emit noise strongly in one direction, where possible, be orientated so that the noise is directed away from nearby NSRs;

w        Silencers on construction equipment should be properly fitted and maintained during the construction works;

w        Mobile plant should be sited as far away from NSRs as possible and practicable;

w        Quiet plants as listed in Project Profile should be used;

w        2m high temporary noise barriers, as stipulated in EP condition 2.9, shall be installed;

w        Movable barrier or acoustic mat should be adopted for the PMEs as listed in Project Profile (refer to Table 4.5).

5.0 Vibration Monitoring

5.1 Monitoring Parameters

The targeted monitoring buildings are Fan Sin Temple and Wun Yiu Liln Site of Sheung Wun Yiu as specified in the Project Profile. They might be affected by the piling process for building a retaining wall along the lower stream of Tai Po River closed to the said premises. The vibration monitoring measures would record the vibration levels at entrance ground level and external wall of Temple building that might be affected by the ground-borne vibration radiated from piling activities in the vicinity.

 

The ground conditions are soil/rocks base; some surface covered by a cement layer, drilling and piling activities involved dropping a heavy weight on the drill and pile heads. Such activities inevitably produced transient vibrations that would propagate from the ground affecting the nearby structures. The effects of vibration on the nearby structures depended its magnitude and frequency, and also on the type of structures themselves. The measured values will be evaluated as to the possibility of cosmetic, minor or major structural damage to the targeted buildings.

 

5.2         Monitoring Methodology

Vibrations samples will be taken using a SVAN 949 analyzer. This analyzer will be equipped with a connecting cable MIL-C-17/28 RG 058 and a DYTRAN 3185D accelerometer. The frequency range shall be set to 200Hz and the number of sampling points shall be set to 1024 resulting in a frequency resolution of around 0.2Hz. Hanning window functions shall be selected and maximum hold functions shall be applied over the event to pick up the peak to peak amplitude.

 

Measurements shall be recorded by attaching the accelerometer to the structural foundation, such as structural steel beam(s) of the building. The accelerometer shall be orientated, either x-, y-or z-directional in order to pick to the maximum amplitude.

 

If measurements have to be taken on a floor or hard surface next to a structure accelerometer shall be attached firmly on the surface3(or to a triangular metal bracket glued tk a spiked plate).

 

 

 

 

  5.3 Monitoring Locations

 Two sites of cultural heritage were identified within 300m of the proposed work area described below in Table 5.1 and Shown in Appendix E.

Table 5.1: Vibration Monitoring Locations

Vibration Monitoring Location	Location
VM1	Remains of a Pottery Kiln at Wun Yiu Village
VM2	Fan Sin Kung Temple at Sheung Wun Yiu

 

5.4 Monitoring Frequency and Duration

Vibration monitoring works will be conducted upon commencement of piling/ drilling process. Monitoring will be carried out weekly in the first month and bi-weekly in the subsequent months of piling/ drilling process during the construction period if no exceedance of limit were recorded. No disturbance will be made to the fabrics of Fan Sin Temple during the vibration monitoring process

 

5.5 Monitoring Results

There was no piling works in September 2008 construction activities. Therefore, vibration monitoring was not required for this reporting period.

 

5.6 Reference Standards

Guidance regarding vibration limits is provided by the following British Standards (or their equivalent ISO standards):

 

▓BS 7385 - Measurement and evaluation of vibration in buildings. Part 2: Guide to damage levels from ground borne vibration.

 

BS 7385 suggests vibration levels, below which damage is unlikely to occur in 95% of buildings.  For cosmetic damage, the level is 15 mm/s at 4 Hz, increasing to 20 mm/s at 15 Hz, increasing to 50 mm/s at 40 Hz and above.  Minor structural damage is possible at vibration levels twice those given above, major damage at four times the levels given in Table 5.2.

 

 

 

 

 

Table 5.2: Transient vibration guide values for cosmetic building damage (BS7385:Part 2 1993)

The vibration magnitudes and frequencies refer to Peak Particle Velocities (PPV) occurring in any single direction, measured on the ground level of the building concerned.

 

5.7 Contingency Plan

Should there be any exceed of limits, i.e. the levels indicated in Table 5.2, ET will notify IEC, ER and Contractor at once. A joint investigation will be carried out in order to identify the possible source and remedial actions required and agreed between ER, IEC, ET and the Contractor. During such investigation, piling and drilling works should be suspended.

 

6.0 Ecological Monitoring

There are four criteria for ecological monitoring at Upper Tai Po River. They include Ecological baseline monitoring, Impact monitoring, Capture survey and Post Construction monitoring.

13.0 Future key issues

Key construction activity in the coming month will be the construction of access road formation and site preparation work. The construction activities may generate some environmental impacts. They include air, and waste

 

The construction site and the site entrance may generate dust. Therefore, proper water spraying, tarpaulin covering and wheel washing at the site entrance are recommended.

.

The site access road formation and site clearance works may generate open stockpile on site. Tarpaulin covering and proper de-silting facilities should be used to avoid muddy water being discharged into the stream.

 

It is expected that construction waste would be generated on site for the boulder trap formation and the gabion wall formation. Contractor shall assign proper designated storage areas for waste and construction materials.

 

 

14.0 Conclusion

The major construction activities carried out by the contractor during this reporting period from September 15^th to 30^th 2008 include access road formation and site preparation works.
