Why Authority Submissions Get Rejected in Singapore (And How to Avoid Delays)

In Singapore, authority submissions are a critical part of any building project.

However, many projects experience delays not because construction failed —but because submissions were rejected earlier in the process.

Whether it involves:

Building and Construction Authority (BCA)
Singapore Civil Defence Force (SCDF)
Public Utilities Board (PUB)
Urban Redevelopment Authority (URA)

submission issues can lead to:

redesign work
project delays
additional costs
coordination problems

In many cases, the root cause is not the submission itself — but the lack of proper planning and coordination behind it.

What causes authority submissions to get rejected?

The most common reasons include:

incomplete coordination between systems
non-compliance with regulations
insufficient technical documentation
late-stage design changes

Most submission problems begin during the planning and design stage.

1. Incomplete Coordination Between Disciplines

One of the most common reasons for rejection is poor coordination between:

architectural
structural
M&E systems

For example:

insufficient ceiling space for services
clashes between ducts, pipes, and beams
inaccessible maintenance routes

When systems are not coordinated properly, submissions often require revision before approval.

2. Non-Compliance with Authority Requirements

Singapore has strict regulatory requirements across different agencies.

Common issues include:

inadequate fire safety provisions
insufficient ventilation requirements
non-compliant sanitary layouts
incorrect system sizing or calculations

Each authority has specific expectations, and missing even small details can result in rejection.

3. Late Design Changes During Submission Stage

Many projects attempt to modify layouts or systems after submissions have already started.

This often creates:

inconsistencies between drawings
outdated documentation
coordination gaps

Late changes increase the likelihood of rejection and delay.

4. Insufficient Technical Documentation

A submission is not just about drawings.

Authorities often review:

calculations
equipment schedules
technical specifications
compliance forms

Missing or unclear documentation can slow down the approval process significantly.

5. Treating Submission as an Administrative Process

One of the biggest misconceptions is assuming authority submission is simply “paperwork.”

In reality, submission approval depends heavily on:

engineering coordination
system performance
code compliance
constructability

Successful submissions begin with proper technical planning.

Why Early Coordination Matters

Many submission problems can be avoided when:

coordination starts early
systems are planned together
constraints are identified upfront

This helps reduce:

redesign work
approval delays
site conflicts during construction

FAQ

Why do BCA or SCDF submissions get rejected?

Common reasons include non-compliance, incomplete coordination, and missing technical documentation.

How can submission delays be reduced?

Early planning, proper coordination, and accurate technical documentation help improve approval success.

Are authority submissions only about drawings?

No. Authorities also review calculations, specifications, compliance requirements, and system coordination.

Summary

Authority submissions in Singapore are often rejected due to:

poor coordination
regulatory non-compliance
late-stage changes
insufficient documentation

Proper planning and integrated M&E coordination play a critical role in achieving smoother approvals.
