We help by highlighting the critical elements that potential influence insurances and building longevity and performance. We also pride ourselves on an ability to be practical and offer informed judgement on design that from time to time needs to be altered or adapted on live sites and help evidence through engineering, that changes can positively contribute to construction.
Logistics & Procurement
The export and import of high-value façade fabric is one of the definitive processes which determine the success of projects which are dependent on the delivery of secured assets.
Fortis have a deep procurement route knowledge which covers land, sea, rail and air transit. We help our clients with:
- Live asset tracking including bill of lading and material certification monitoring
- Independent review of factory output and shipping manifests to validate capacity and production timing
- Custom packaging and protection design
- Regional and local independent monitoring of:
- Extraction
- Manufacture
- Fabrication & Assembly
- Custom Inspection Test Plans (ITPs) for Quality Assurance & Quality Control
- Sustainability Practices: Emphasising sustainability in logistics practices, such as optimising routes to reduce carbon emissions and recommending eco-friendly materials, aligning with environmental goals, from transit method to packaging
- Security Measures: Review of storage facilities insurances and deterrent facilities and general management
- Risk Management: Implementing proactive risk management strategies to identify potential delays or problems before they impact the project, thereby minimising downtime and cost overruns by reviewing available contingency logistics.
Façade Access & Maintenance
Property remains one of the safer investment markets. The ability to maintain assets reduces the dilution of valuations, Fortis prescribe tailored access and maintenance strategies to ensure safety and longevity in fabric management.
Fortis offer the following:
- Evidence of hierarchical approach to access strategies in accordance with CDM responsibilities and prevailing standards and best practice guidance whilst providing cost considerations which are appropriate.
- Access device engineering and integration with façade structure including accounting for imparted loads.
- Comparative analysis of varied access designs through cyclic modelling to provide time and budget considerations for the costing teams.
- Atmospheric analysis through our unique BIOME offering we can determine the optimum periods of maintenance and general cleaning, we consider:
- Materiality
- Specific regions through meteorological profiling of exact site location
- Seasonal influences: drying potential, surface asperity, building shading, frequency and duration of exposure
- Façade fenestration and relief
- Replacement strategies for all materials including plant, operative requirements and sequential planning.
Building Physics
Using industry recognised software we offer an ability to gain insight into the way in which building fabric interacts with the world we live in. This is not only the atmospheric process that drive our planetary weather systems but also the way in which we occupy buildings.
Our specialist teams can provide hydrothermal analysis of construction interfacing whether it be new build or existing. We provide steady-state analysis and dynamic simulation to assess the following:
- Design to regional codes
- Mould growth propagation
- Mould risk analysis
- Identify potential ecological species
- Drying potential
- Interstitial condensation
- Surface condensation
Fortis do not rely solely on predetermined climatic data sets provided by others which are often built-in or plug-in to software. We use a combination of GIS and atmospheric data specific to your region from approved data loggers and weather stations to accurately represent conditions buildings experience, as opposed to general region. This can positively influence sustainability by reducing material needs but also highlight areas which require resilience design, and therefore increases longevity of building materials which respond and accommodate the environment intended for.
Refurbishment & Preservation
Fortis provide detail existing condition surveys which highlight scopes of works required to achieve client aspirations.
Fortis have helped lead industry within the last 5 years for combining understanding of old structures, their construction methodologies and building materials with the need for modern day adaptation. Part of the challenge we face is the interfacing of modern technologies with structures that have once operated not only with traditional mechanical and electrical design, but the very fabric and the construction differs such that it can hinder and even restrict the introduction of modern materials.
Having an appreciation of where we have come from is essential in understand where we’re going. Fortis pride our historic knowledge on different construction eras through to significant cultural heritage works. It’s this knowledge, combined with our multi-disciplinary approach to façade engineering that allows for a balanced assessments that are sympathetic to each project.
Where validation of existing building material requires evidencing extension of service life, we coordinate on behalf of the client using prevailing regional standards with laboratory or on-site testing where applicable.
Innovation & Research & Development
Fortis can help companies with façade product development through completing engineering analysis and coordinating independent testing.
We partner with specialist patent advisors who help clients with Intellectual Property applications whilst providing innovation through either reverse engineering or composite design. We work with clients to identifying unique product properties that qualify as genuine innovation that help drive industry forward.
Fortis work across engineering and environmental disciplines to help answer challenging questions that can not ordinarily be answered by traditional design and engineering. We created BIOME a scientific division to amalgamate environmental sciences and engineering disciplines so that building envelope design can be accountable by innovating the approach through detailed atmospheric and regional environmental profiling to reduce risk profile for building insurance.
Resilience Design & Engineering
Building envelopes, through design can be made to serve several functions either at the same time or when required. This design ensures materials that typically are a focus of aesthetics, carry inherent embodied carbon and are essentially only passengers attached to the side of structures are consistently working during the design and service life period.
Fortis have a track record of showing design teams how we can create responsive design to occupancy and adapt to seasonal climates but also climate profiles which perhaps have not reach us yet. This creates a façade that is not appearance centric but one which has longevity and ability to recover or manage permutations experienced across the fabric; a resilience façade.
We combine historic meteorological data, live climatic trends and project climates forwards to qualify engineering judgement so that specific facade responses are realised at the start of design processes and can be budgeted for. This body of works will always contribute to sustainable accreditation and has preservation at the heart of the process.
Forensics & Investigations
Fortis are independent specialists who have experience across industry standard and non-standard façade systems. Our experience comprises of first-hand design, engineering, manufacturing, fabrication and installation this places us in a unique position to audit others works and investigate latent defects or quality of workmanship.
We use a multitude of techniques which we can use to assist in reporting, such as but not limited to; coordination of laboratory test analysis, use of on-site specialist equipment, statistical analysis, historical referencing and context reporting, and other trade techniques depending on the objective. Having these facets allows us to tailor our approach to almost all building related issues and get to the causation in a timely manner whilst providing rationale for record keeping and peer review.
“I worked with David on a large mixed-use project between 2017 and 2021 when he provided technical advice to one of my clients on some cladding defects.
As a technical expert, David is impressive. His technical knowledge and passion for the subject make him stand out. He has a rare combination of qualities which make him a pleasure to work with and I would not hesitate to recommend him. I look forward to future opportunities to work with him.”

I have had the good fortune to work with David since 2018. While both of us were at Inhabit I relied on him daily and more recently (at Mace Facades) we continued to work on projects together.
David’s flexibility and thirst for knowledge coupled with his conscientious manner meant that I could always rely on him to do the best for our clients from a technical, budget and practical perspective. I hope to work again with him and look forward to seeing his new venture and team grow over the coming years.”
