2. The DfS Professional shall propose a systematic review process for Authority (LTA)'s approval. For example, to assist the stakeholders in reviewing the design and construction, the GUIDE process developed by the Workplace Safety and Health Council in the DfS Guidelines can be implemented :

a) G - Group together a review team consisting of major stakeholders.

b) U - Understand the full design concept by looking at the drawings and calculations, or have the designers elaborate on the design.

c) I - Identify the risks that arise as a result of the design or construction method. The risks should be recorded and analysed to see if they can be eliminated by changing the design.

d) D - Design around the risks identified to eliminate or to mitigate the risks.

e) E - Enter all the information including vital design change information affecting safety and health or remaining risks to be mitigated into the DfS Register.

3. The DfS Professional shall adopt LTA Safe-to-Build Project Safety Review Process in preparing DfS Register via Civil Design Safety Submission (CDSS), Civil Construction Safety Submission (CNSS) and Civil Handing Over Safety Submission and make presentation to LTA at Project Safety Review Meeting chaired by LTA Representative for approval. Civil Construction Safety Submission (CNSS) shall cover risk associated with ERSS works, excavation works, piling works, reinforced concrete works, backfilling to station box / cut-and-cover tunnels, mined tunnels, sewer pipe jacking works, manhole construction, strut removal, architectural works (including architectural provisional items), etc. All residual risks that cannot not be closed at CNSS stage shall be transferred to Civil Handing Over Safety Submission and approval by the Project Safety Review Committee must be sought before handing over the residual risk to appointed Rail Operator.

4. The DfS Professional shall review all method statement and risk mitigation measures proposed by each sub-contractor before contractor project director approves the method statement / risk mitigation measures. Thereafter, DfS Professional shall carry out a monthly review meeting with the Designer, contractors / sub-contractors on DfS Register and carry out at least three site inspections at weekly interval to check that all mitigation measures proposed are implemented at site. The DfS professional shall monitor performance of ERSS via instrumentation readings obtained via the Authority appointed Instrumentation Contractor. Proper site record shall be submitted to the Contractor Project Director on his findings for each site inspection. The DfS Professional shall record all review meeting with proper minutes of meeting and seek approval of the review meeting minutes by the contractor Project Director.

5. The DfS Professional shall make presentation on DfS Register including all update on CDSS, CNSS at LTA Monthly Risk Register Meeting chaired by the Engineer's representative and LTA Director Quarterly Risk Register Meeting. The DfS Professional shall prepare minutes of meeting for these meetings. Upon completion of relevant activities or works, the DfS Professional shall seek approval from LTA to close the hazard identified and submit the Hazard Closure Form to LTA for approval.
