1.4 General Introduction to the Procedures

For the purpose of determining if a Construction Noise Permit for

percussive piling should include restrictions on the hours during which

percussive piling may take place (referred to in this Technical

Memorandum as the permitted hours of operation) the Authority shall act

in accordance with the following general procedures which are detailed

in subsequent sections. The Authority shall :-

(a) identify the most affected Noise Sensitive Receiver and determine

the appropriate Acceptable Noise Level (in accordance with Sections 2.1

and 2.2);

(b) calculate the Corrected Noise Level which will be generated by the

percussive piling at the Noise Sensitive Receiver (in accordance with

Sections 2.3 to 2.8); and

(c) determine the appropriate permitted hours of operation for the

percussive piling by comparing the Corrected Noise Level with the

Acceptable Noise Level (in accordance with Sections 2.9 and 2.10).

The Construction Noise Permit issued by the Authority shall include the

permitted hours of operation as a condition, and may include such other

conditions as the Authority considers appropriate, such as the

permissible piling methods and pile types which may be used,

the area

within which percussive piling may take place (referred to in this

Technical Memorandum as the piling zone), the dates of commencement and

expiry of the Construction Noise Permit and any special noise control

measures that must be adopted.

A Construction Noise Permit may be issued for an initial period of such

duration as the Authority considers appropriate, and may be renewed

before or after the date of expiry for such further period or periods

and subject to

to such alterations or new conditions as the Authority

considers appropriate.
