Letter of No Objection (LNO)

Our Fire Safety Engineers can issue Letter of No Objection (LNO)

With no prejudice, it is not mandatory but usually a common and cost-effective practice for building owners to engage the base Fire Safety Engineer to assess the impact of alterations and additions to the existing performance-based designs for the issuance of the Letter of No Objection (LNO) to SCDF (AHJ).

However, for unforeseen circumstances, the owners may also engage an independent Fire Safety Engineer for the issuance of the LNO.

We will review the impact of alterations and additions to the building’s existing Performance-based Fire Safety Designs for compliance with the life safety, fire protection and acceptance criteria against the performance objectives of the prevailing fire code.


When necessary, we will assist Owners to purchase the performance-based documents (FEDB, FER, O&M) from the SCDF (AHJ).
