Safety Ethos

We strive every day to ensure the workplace is a safe environment for all our people and those we work alongside.   At Weltec, we believe that safety innovation comes from individuals and teams and we continuously and actively encourage all our staff members to provide their input and point of view for increased safety performance. We believe that diverse perspectives lead to broader and more informed thinking and this allied to our culture of Continuous Improvement sets Weltec apart as a leader in Health and Safety management.


Clear, effective and continuous communication with all our employees of our safety objectives and the desired work practices that will safeguard their health and wellbeing is every bit as important as the policies, procedures and safety management system that underpins world class safety performance.


As a contractor on Essential Projects, Weltec Engineering continues to operate fully as a business.  Safety is always our number one priority, and it has never been more evident than it now, as we continue to face the unprecedented in our lifetime COVID-19 pandemic which continues to spread around the entire world. Our leadership team across the company is working continuously to ensure our people are safe, well informed and fully prepared to take care of themselves and their families through this time of uncertainty.

We are continuing to safely deliver projects, while adhering to work practices that are fully in compliance with all advice from the World Health Organisation (WHO) and the HSE and Irish government’s guidelines.  We operate on all sites strictly in compliance with the latest Construction Industry Federation’s (CIF) C19 Pandemic Standard Operating Procedures. 

We owe a huge thanks to our staff, clients & supply-chain who are working hard during this difficult time.  A number of the company’s support staff are successfully supporting on projects from home, with our IT team having successfully implemented IT infrastructure upgrades to maintain business continuity and ensure no disruptions to client projects.

The safety of all our people and those we work alongside together with the success of our clients projects will remain our focus as we move forward through these uncertain times. UPDATED 21/01/2021

Our guarantee of the highest quality standards

Quality Assurance

At Weltec our quality management system is our guarantee of the highest quality standards across all disciplines and all projects.   Underpinned by our Core Values of Preparation, Exceeding Expectations and Continual Improvement our people strive to ensure our clients always receive the highest quality services and workmanship.

Our system is independently certified by NSAI to ISO9001:20015 standards. This means we have independently-verified quality system in place across all our projects, from the quality plan, test and inspection matrix, installation checks, materials receipt verification, materials and work traceability, red lines, walkdowns, testing, commissioning to final handover.

Digital QA

At Weltec we have embraced the advantages of the digital age, integrating internet and mobile technology into our construction quality control plans.   As all projects move from paper drawings and documentation to digital and internet technology, quality assurance and quality control have become more effective and better at mitigating risks than ever before.

We have made major investments in digital construction processes including BIM, Contract Management software system and test pack generation software for all our projects. Along with improving overall project efficiency and quality this also provides greater visibility and traceability for clients throughout the entire construction build process.


At Weltec we recognize the responsibility placed upon all of us to protect and enhance the environment for future generations.   As an Engineering and Construction company we have an important role to play to help ensure the long-term sustainability of the construction industry.

We are committed to taking account of all the possible environmental implications of our project work and to ensure that potential adverse environmental impacts are comprehensively risk assessed, mitigation steps taken and opportunities for delivering environmental improvements are maximised.

We recognise the value inherent in the design and construction of sustainable engineering projects and where possible support the integration of sustainability into the building and engineering design process.

We have considerable experience in delivering BREEAM and LEED accredited buildings.  

We are accredited to internationally recognised ISO 14001 Environment Management System (EMS) a systematic framework to manage the immediate and long term environmental impacts of an organisation’s products, services and processes.

We firmly believe that our environmental and sustainability goals are key to ensuring, that as a company, we promote a continuous cycle of improvement, aimed at developing work practices and options that are less wasteful, more sustainable and more environmentally friendly.

The winning project

Sean Treacy

Title: A Critical Analysis of the Energy Performance of LEED Accreditation and a Comparison of Different Level LEED Certifications in a Medical Device Manufacturing Facility

This dissertation evaluated the effect LEED accreditation has had on the performance of certain buildings within Pharmaceutical Facility. As the facility has different levels of certification within the one facility, a comparison of the different certification levels was made in terms of the building’s energy usage and carbon emissions. An analysis was made on the effectiveness of LEED accreditation for the energy usage and reduction in carbon emissions for this facility. Ultimately, this dissertation seeks to find out was LEED accreditation beneficial for this facility from an energy and carbon emissions point of view.


These awards was established to showcase the exceptional work that final year students of the Sustainable Energy Engineering course produce in SETU.

SETU and Weltec Engineering

The winners were announced on the day,

2nd place was John Murphy, for his project Titled: Water Loop Heat Pump Systems.

3rd place was Mark Treacy for his project Titled: Decarbonisation of Heavy Duty Vehicles in the Construction Industry in Ireland.


All 3 were issued with relevant certs from Weltec. Weltec acknowledges the efforts of all participants are proud to have established a solid link between themselves and WIT/SETU over the years.
