When you hire an engineering or construction solutions company, you’re not just buying a service. You’re trusting someone with your budget, your timeline, and your reputation. So the question isn’t just “Can they do the work?”, it’s “Can I trust how they do it?”
An Integrated Management System combines multiple international standards into a single, unified manner of running a company. Instead of separate systems for quality, ethics, and compliance that never communicate, an IMS weaves them together into one consistent approach.
Think of it this way: without an IMS, a construction project management service might have a quality process in one department and an ethics policy in another.
With an IMS, every decision, from how you hire suppliers to how you document costs, flows through the same verified, auditable system.
For quality QS consultancy services, this means your quantity surveyor Philippines based or international, follows the same documented process every time, regardless of who’s assigned to your project.
For Quantity Solutions Inc., our IMS combines two internationally recognized certifications:

This standard means we have policies, controls, and processes in place specifically designed to prevent bribery and corruption in our company and in the projects we handle. It covers how we deal with clients, suppliers, government agencies, and third parties. Every decision goes through an ethical framework. Nothing gets done under the table.
Quantity Solutions Inc. became ISO 9001:2015 certified in 2013, establishing a documented, auditable quality framework across all our quantity surveying and cost management services.

This is the world’s most widely recognized quality standard. ISO 9001 means our workflows, deliverables, and client communications follow documented, audited processes. So you get the same quality every time, not just when the right person happens to be on the job. It also means we’re committed to continuous improvement, catching problems early and fixing them systematically.
In 2024, QSI added ISO 37001:2016 certification, formalizing our zero-tolerance stance on bribery and corruption with a verified management system covering clients, suppliers, and third-party engagements. Making QSI one of the first engineering firms in the Philippines to hold both ISO 9001 and ISO 37001 simultaneously.
Together, these two certifications form our IMS, and they’re not just plaques on a wall. They’re audited by independent third-party bodies, which means our compliance is verified, not self-declared.
The Philippines has a construction industry that is growing rapidly, fueled by government infrastructure programs like Build Better More, rising private real estate development, and increasing foreign investment. However, expansion also creates pressure, which leads some businesses to take short cuts. Some charge for work that wasn’t done. Some pay to make problems go away.
According to Transparency International’s Corruption Perceptions Index, corruption in the construction and procurement sectors remains a documented concern in the Philippines. Projects go over budget not always because of market forces, sometimes because of:
Working with a company that has ISO 37001:2016 and ISO 9001:2015 certification removes these risks. Not because problems are impossible, but because there are documented systems designed to catch and prevent them before they cost you.
“In an environment where informal arrangements are common, working with a certified company is one of the few ways to contractually guarantee ethical and quality standards.”
When you engage a construction project management service with ISO certification, you receive:


In the Philippines and anywhere, the difference between a project that is completed within budget, on time and without issues and one that does not, often comes down to the processes behind the people.
At Quantity Solutions Inc., our IMS isn’t a marketing tool. It’s how we work, every project, every client, every time. Whether you’re a local developer, a government agency, or an international firm entering the Philippine market, that’s the standard you deserve from the company you choose.
