Values to be adopted unless otherwise advised by the Authority at Development Plan Stage. The interpretation of track twist, vertical and horizontal alignments is given in Drawing no. LTA/DBC/CPRP/011. Track values above refer to the allowable deformations to the track in comparison with the conditions prior to construction activities. This is dependent on the design capacity of the bearings and the structure system of the different rapid transit structure. Other structural constraints such as tie beams and cross beams that form an integral part of the rapid transit systems viaducts in the particular rapid transit systems station must be considered in detail when applying these guidelines. Load that the rapid transit systems structure, except for sub-aqueous structures, are designed for. For structures influenced by load imposed from an existing building, the self weight of the existing building with appropriate allowance for live load in accordance with BS 6399 shall be applied as imposed load at the foundations level of the building.

GUIDELINES FOR INSTRUMENTATION PROPOSAL 1 1.1 General This set of guidelines serves to stipulate the minimum requirements on instrumentation proposal to enable close monitoring of the effects of any development or building works on the rapid transit systems structure, tracks and the ground. The Authority reserves the right to impose any additional requirements deemed necessary to safeguard the rapid transit systems. Provision of Instrumentation The types and quantities of instruments to be provided will largely depend on major factors such as the configurations of construction works, the closeness of these works to the rapid transit systems structure, the method of construction, the soil conditions on site, etc. The types of instruments and frequency of monitoring shall, however, comply with the minimum requirements given in Table E-1. Automatic Trainway Monitoring System and Manual Survey Extent of Monitoring The extent of monitoring shall extend at least 20m beyond the predicted influence zone of the works. The spacing of the targets in this area shall not be more than 5m. Within the predicted influence zone of works, the spacing of targets in the rapid transit systems tunnels and stations shall not be more than 3m and 5m apart respectively. Each monitored section consists of 4 units of targets mounted at the crown, track slab and side walls. Automatic System Trainway Monitoring (b) Appropriate features should be incorporated into the system to take readings only when a train is not passing by to reduce these effects; (c) Readings shall be obtained at time interval that is practically continuous; (d) Capable of measuring the absolute displacement and distortion of the rapid transit systems structure; (e) The instrument shall be able to automatically start each measurement cycle at the pre-set time and stored the produced record for later retrieval; (f) The system accuracy shall be better than ±1mm; in 50m taking into consideration the effects of train operation and changes in ambient conditions such as vibration, changes in air pressure and temperature (g) The monitoring readings obtained for two consecutive readings at the same monitoring point when not disturbed by construction activities or train operation, etc (for example, at night) shall not deviate from each other by more than 0.5mm; and (h) The software used for operating the automatic monitoring shall be reliable with proven performance in other projects of similar capacity and conditions. The track record of the application software used in other projects shall be submitted for approval. 3.2.2 All control points or datum for measurements shall be located outside the influence zone of the proposed works. The automatic monitoring should be supplemented with manual physical survey monitoring of movement of the rapid transit systems structure conducted by registered land surveyor at regular intervals as a check on the performance and results of the automatic system. Manual survey shall satisfy the requirements Clause 3.3.

(d) Manual survey as a check for the automatic monitoring system shall be based on the same co-ordinate system and absolute co-ordinate shall be correlated. 3.4 Calibration of Instrumentation Equipment The total station used for monitoring shall be calibrated once at every 6 months interval by an accredited testing laboratory. Certification of the monitoring equipment shall be submitted to the Authority for verification. 3.5 Left-in Anchor and Bolt The type of anchor and bolt to be used for supporting installation in the train way is standardised to HKD-SKR or equivalent.
