Dear Shiela,

 

Please see our revised method statement for Park Street as attached for your review.

 

Regarding your reinforcement details, we will follow the construction drawings. Please see the drawings as attached. However, we will be unable to backfill the portion under the constructed footpath for the pre-cast sections due to the construction method.

 

 

Additionally, we will also not be able to remove the formwork for the cast insitu method of construction.

 

Please see the endorsed drawings for the precast segments and the lifting details.

 

Please do let me know should you have any additional queries.

 

Thank you.

Dear Shiela,

 

As discussed, please see the method statement (powerpoint) for Park Street near Marina One in the link as shown below, for your comments if any. The PDF file is attached for your reference.

As communicated previously, we will use the cast in-situ construction method at the tapering locations.

 

With your no objections, we will proceed to send it to URA CST for approval to start works.

 

Thank you.

Hi Shiela,

 

Please see our amended TCP as shown in the link below:

Park Street TCP

 

As discussed, we would very much appreciate your assistance in helping to apply for the ERIMS permit so that we can close the lane to facilitate our works at Park Street.

[Shiela ANG (LTA)]

Hi Geyi,

Please see the notification number for the above-mentioned location for construction of cycling path.

Reminder to update the following inside the WhatsApp group :-

1. Before works start photos to ensure work area is safe to start
2. After works end – Housekeeping and timely reopening of lane etc
3. Your tapering distance to comply with the LTA COP in accordance with the Speed Limit of the road location as per your TCP.

Please also ensure to update LTA prompt prior to lane closure and update BusOps.

 

Thank you.

 

Best Regards,

Shiela
