Comprehensive RE & RTO Services

Resident Engineers Services

A resident engineer is the primary on-site representative for major construction projects, regularly checking drawings, site work, and technical details while supervising construction in accordance with approved design specifications, building codes, and safety regulations. For business owners, property developers, project owners, and construction professionals in Singapore, understanding the RE job scope is essential when you need reliable site supervision, regulatory compliance, and quality control that keep complex works moving and help prevent delays, disputes, and penalties.

Our Resident Engineers act as the main on-site point of control and coordination. This guide outlines resident engineer and resident technical officer services, supervision duties, BCA-related compliance requirements, construction safety integration, and the codes and standards that apply in Singapore. We offer:

BCA Requirements for Qualified Person and RE/RTO Appointment

The Building and Construction Authority (BCA) of Singapore has established comprehensive requirements for the appointment of Resident Engineers and Resident Technical Officers. Under the Building Control Act, Singapore requires accredited supervision personnel, including approved companies involved in supervision appointments, and accreditation as a resident engineer has been mandatory since 2009. Understanding these requirements is crucial for project owners and developers to ensure compliance and avoid potential penalties. Applicants are typically expected to have relevant experience, possess a diploma or degree in Civil or Structural disciplines, produce original diploma or degree certificates for verification, obtain IES/ACES accreditation under standards supported by the relevant professional institution, and, where required, hold Professional Engineer registration so the qualified person overseeing the works meets regulatory standards. This original-certificate requirement applies from 2026, and applicants may also need to send supporting documents after the online submission process where applicable. To continue practicing, such personnel must maintain their status, which can also enhance their knowledge through training opportunities and seminars.

Project Categories Requiring RE Appointment

Code Compliance and Standards

RE/RTO supervision must ensure compliance with numerous codes and standards, and effective oversight starts with strong knowledge of applicable building codes and safety regulations, as RE/RTO personnel check applicable codes, drawings, and site procedures against current standards:

Primary Codes and Regulations:

• Building Control Act and Regulations

• Singapore Standards (SS) for Construction

• Code of Practice for Structural Design

• Fire Safety Code

• Accessibility Code

• Environmental and Sustainability Standards

Industry-Specific Standards:

• SS EN 1992 (Eurocode 2) for Concrete Structures

• SS EN 1993 (Eurocode 3) for Steel Structures

• SS EN 1997 (Eurocode 7) for Geotechnical Design

• CP 65 for Lighting of Roads and Public Spaces

• PUB Codes for Water and Sewerage Works

Safety Integration in RE/RTO Services

Safety Oversight Responsibilities

While primary safety responsibility lies with contractors under Singapore’s Workplace Safety and Health Act, REs and RTOs play a crucial supporting role in promoting and monitoring safety compliance. Our approach integrates safety considerations into all aspects of supervision without diluting the contractor’s accountability.

Safety Monitoring and Reporting

• Daily Safety Observations: Our site teams conduct regular safety walks, checking site conditions, documenting observations, and keeping detailed records of follow-up actions while bringing concerns to the contractor’s attention for immediate action

• Method Statement Review: All method statements and contractor instructions or submissions are reviewed for safety implications, ensuring risk assessments are comprehensive and control measures adequate

• Incident Reporting: Any safety incidents or near-misses observed are immediately reported to ensure proper investigation and corrective action

• Safety Performance Tracking: We maintain records of safety observations and contractor responses to identify trends and recurring issues

• Authority Liaison: Coordination with MOM inspectors during site visits and follow-up on any directives issued

High-Risk Activity Supervision

Certain construction activities require enhanced supervision due to their inherent risks:

Lifting Operations

• Verification of lifting plans and calculations

• Confirmation of crane certifications and operator licenses

• Monitoring of exclusion zones during lifts

• Weather condition assessments

Working at Height

• Inspection of edge protection systems

• Verification of scaffold certifications

• Monitoring of safety harness usage

• Oversight of opening covers and barriers

Excavation Works

• Inspection and quality control of excavation works, including check of shoring installations and excavation support conditions

• Verification of confined space procedures and related tests

• Checking of access and egress provisions

• Oversight of excavation support systems

Frequently Asked Questions

What is the difference between an RE and RTO?

A Resident Engineer (RE) is typically a Professional Engineer who provides overall supervision of construction projects and acts as the Qualified Person’s site representative. The role typically requires a Bachelor’s degree in Civil Engineering or a related Civil/Structural qualification, plus experience in supervising construction and inspecting workmanship. In Singapore, Resident Engineers commonly earn about $7,000 to $8,500 per month, and the market includes over 6,000 Resident Engineer job listings. They have broader responsibilities including coordination, quality oversight, liaison with authorities, and managing Resident Technical Officers on site. REs also need technical skills in quality assurance and contract management, along with strong communication, problem-solving, leadership, organizational, and other essential skills.

A Resident Technical Officer (RTO) provides specialized technical supervision in specific areas such as structural works, geotechnical works, or M&E installations. RTOs work under the direction of the RE and focus on detailed technical compliance.
