Each team of 20 to 25 people
Each crew of 2 to 3 people
When designing an integrated building system, it is essential to combine the HVAC, water supply, ELV electric, electrical, and fire fighting systems to ensure that installations do not overlap Proper cable pulling and laying techniques are crucial for maintaining efficiency and safety within these interconnected systems.
* Pulling cable on ladder & trunking
- Before putting up wide cable conduct discharge each cable wires in rulo cable, using specialized cable discharge arm with large cross section
- Conduct scattered each cable wire by circulating method, prohibits use drag-end scratch and stretch cables
- When all of the cable in a process have finished, conduct rearrange and positioning them in ladder by nylon cable ties, ensure that the parallel cables and no cross,confusion
To install the cable across the floor, an electric winch is mounted on the roof of the technical box to facilitate vertical hooking This process begins with securing the cable into the cable ladder that has already been installed.
To ensure labor safety, the technical box application will be utilized to clean the working platform on all floors To facilitate synchronized operations between the upper and lower levels, as well as with the electric winch operator, contractors will provide radios for effective communication during this process.
To ensure a smooth inspection process, the team leader must oversee the organization of all scattered cable wires along designated lines Each cable line should be clearly marked according to the specifications outlined in the drawings, and these markings must receive approval from the main contractor and consultant.
- All other exceptions and problems encountered during the construction must be reported to suppervidor try to correct, not arbitrarily constructed to avoid serious consequences later
To ensure proper identification of cable phases, mark the two exposed ends of the cable with colored glue, adhering to the approved construction drawings It is essential to maintain the colored tape markings from the moment the cable is pulled until the electrical panel connection is completed.
* Pulling cable method in PVC conduit
- Before pulling the wire, must used bait thread through all the PVC conceal conduit to fix the broken pipes or stuffy concrete during concreting
- PVC conduit conceal are filled befor pulling cable
- Follow shopdrawing approved, prepared raw wire coil and node rope Threaded bait thread in section PVC conduit for pulling wire
To ensure proper identification, mark the two exposed ends of the cable with colored glue, adhering to the approved construction drawings It's essential to maintain the colored tape markings from the moment the cable is pulled until the connection to the electrical cabinet is completed.
When connecting equipment to electrical cabinets, ensure that the wiring length is reasonable for easy connections For ceiling-mounted lights, use a wire length of 20 cm, and for recessed ceiling lights, extend the wire over the gypsum ceiling by 20 cm Additionally, maintain a rectangular length at the electrical cabinets and a wire length of 15 cm for switches.

Evaluate the risk and decide on precautions
Table 1 outlines consequence levels by assigning numerical values that define their impacts on environmental, health and safety, production loss, and property damage In cases of uncertainty regarding which outcome presents a greater risk, it is advisable to evaluate both scenarios and choose the one with the higher risk level.
Where there is doubt as to which outcome would have the highest risk level, both should be considered with the highest one being selected
Negligible impact on strategic objectives Nil/negligible:
Injury, loss, service interruption, environmental/estate impact, impact on reputation impact on quality litigation or complaint
Small variance from overall strategic objective First aid treatment with full recovery
Complaint possible Local low key external interest
Minor: financial loss (up to 5K),service interruption
,environmental/estate impact, impact on reputation, impact on quality
Notable variance from overall strategic objective Medical treatment required up to 3 months to recover
Reportable under RIDDOR(Reporting of Injuries, Diseases and
A moderate financial loss ranging from $5,000 to $200,000 may occur, accompanied by service interruptions lasting over one week This situation can lead to environmental and estate impacts, as well as damage to the organization's reputation Local press and stakeholders are likely to express concern, highlighting the implications on quality Additionally, there is a moderate risk of losing recoverable information, which could result in low-value claims.
Significant variance from overall strategic objective Long term illness or injury (up to one year)
Reportable under RIDDOR Complaint expected/received
A major incident can lead to financial losses ranging from $200,000 to $3 million, along with service interruptions exceeding one month The environmental and estate impacts may further exacerbate service disruptions, resulting in significant reputational damage Such events often attract extensive media attention for over a week, raising serious concerns among stakeholders Additionally, the overall quality of service may decline, increasing the risk of failing to meet established performance standards.
‘excellent’ in annual health check in one or more standards, major loss of information (recoverable) , high value claim or action by HSE anticipated, moderate risk of low value claim
Failure to meet strategic objective threatens independent functioning or stability
The potential consequences of a significant data breach include severe financial losses exceeding $3 million, reputational damage highlighted by national press coverage lasting over three days, and the risk of long-term or permanent loss of critical information affecting service delivery quality External controls may be enforced, and the threat of judicial review looms, with anticipated litigation costs surpassing $1 million Additionally, high-profile breaches involving confidential information, such as patient identities, can lead to the condemnation of buildings or properties, resulting in substantial service disruptions.
Likelihood can be examined with regard to the chance that a particular outcome will happen to any of the following:
• A single person or member of the general public
• The project (more persons potentially exposed)
Table 2 outlines the Likelihood Levels, assigning numerical values to varying degrees of likelihood This variability highlights the importance of using the designated Likelihood Level for a "Project" to ensure the safety and protection of individuals involved.
Scor e Descriptor LIKELIHOOD OF REPEAT EVENT
1 Very unlikely to occur Will only occur in exceptional circumstances
2 Unlikely to occur Unlikely to occur but the potential exists
3 Could occur Reasonable chance of occurring – has happened before on occasions
4 Likely to occur Likely to occur – strong possibility
5 Almost certain to occur The event is expected to occur in most circumstances
• Use the Risk Matrix Tool and guidance in the Risk Assessment pro forma to grade the risk
Negligib le Minor Moderate Major Catastroph ic / Fatal Consequence
A combination of Tables 1 and 2 can be used to evaluate the risk by determining the overall risk level of a particular outcome eventuating
The matrix (Table 3 - Risk Level Matrix) below is shown in the conventional format of
Consequence on the horizontal axis increasing to the right and Likelihood on the vertical axis increasing with height
Escalation of Risk is determined by risk score
Risk level Risk score Escalation level
Extreme Red 15- 25 Board of Directors
High Orange 9-12 Management committee (reporting to Board) Moderate Yellow 6-8 Directorate/Department
Department but monitored at Directorate level
• For an initial risk assessment, the Risk Level is known as the Risk Factor Number
• For a residual risk assessment, the Risk Level is known as the Residual Risk
• In both cases, the risk level dictates the response and timing of risk controls required
The management of risks identified through the risk assessment process will be determined by the risk rating
The amount of effort/resources that are to be committed to an identified risk is determined by the risk score The Contractor has a scheme of escalation
• Risks scored 1-5: are considered low risk (L) and therefore risks are accepted
(tolerated) by the Contractor No more countermeasures are required.
