2. ASSESSMENT OF NOISE FROM THE CONSTRUCTION WORKS

2.1

Step 1

(NSR)

Location of the Most Affected Noise Sensitive Receiver

The NSR which will be most affected by noise from work on the

construction site shall be identified.

For the

purpose of this Technical Memorandum any domestic

premises, hotel, hostel, temporary housing accommodation, hospital,

medical clinic, educational institution, place of public worship,

library, court of law,

of law, performing arts centre or passive recreational

area shall be considered to be a NSR. Any other premises or place, not

being in the nature of either industrial or commercial premises, which is

considered by the Authority to have a similar sensitivity to noise as the

premises and places above shall also be considered to be a NSR. Any

premises or place shall, however, be considered to be a NSR only when it

is in use for its intended purpose.

The term "passive recreational area" includes district and

local open spaces and childrens playgrounds, where such places are used

for passive recreation, but does not include small sitting out areas.

Where a premises or place is used for a mix of passive and active

recreational uses the major use should be considered when determining if

the premises or place is a NSR. Where a large area of mixed recreational

use is concerned it may be appropriate to subdivide it into active and

passive areas to be considered separately.

2.2.1

Step 2 - Determination of the Area Sensitivity Rating (ASR)

General

The ASR is a function of the type of area within which the NSR

is located and the degree of the effect on the NSR of particular

Influencing Factors (IFs) as defined in Section 2.2.3. After a careful

examination of the area under consideration and the effect of any IFs,

the ASR may be determined from Table 1.
