Non-standard on-site testing & monitoring

For non-standard services, we normally propose project-specific test method, based on the nature of the projects and customer’s needs. Please click the “Reference projects” tab above for some examples.

On-site color uniformity testing

We have 6 reference projects in this category, 5 on glass color uniformity and 1 on cladding material color uniformity.

On-site facade performance & micro-climate monitoring

We have 3 reference projects in this category, 1 on thermochromic glass performance monitoring, 1 on low-e glass performance monitoring and 1 on micro-climate monitoring.

Largest collection of optical & thermal instruments in Singapore

OTM maintains the largest collection of optical & thermal measurement instruments in Singapore. 

The instruments were used in our past projects. As the distributor of a few reputable instrument manufacturers, we are able to get access to high precision instruments at more competitive prices. Additionally, we also have in-house capabilities to design and integrate measurement instruments.

Cost

The cost is project dependent. We will propose a fee based on the nature of the project (e.g. instruments needed, project duration, manpower required in result analysis and reporting).

Please contact us for discussions on your project.

Lead time

If we have existing instruments, we will be able to start the project in 1 – 2 weeks or earlier; if we need to order additional instruments, we will be able to start the project in 4 – 5 weeks after your confirmation.

For monitoring projects, we will need additional 2 weeks for result analysis and reporting.

Procedures

Below are the typical procedures for an on-site testing & monitoring projects:

1. We will visit the site to understand the site conditions and the project nature;
2. We will write a project based on our site visit and mutual discussions;
3. If the proposal is acceptable to the customer, we will provide an official quotation, with the agreed proposal as the attachment
4. The project will start after the customer’s confirmation.
