OUR EXPERTISE
COMPREHENSIVE ENGINEERING EXPERTISE FOR YOUR PROJECTS
The Engineering Group brings together complementary expertise to support construction, renovation and transformation projects, from initial definition through to final delivery.
Client advisory, project management, construction cost management, structural engineering, building services, energy performance, fire safety and construction management: our collective approach enables every project to be considered as a whole, while mobilising the right expertise according to its specific requirements.
This complementary approach enables us to support complex and demanding projects, in both new-build and refurbishment, with particularly strong experience in high-end developments, hospitality and mountain environments.
CLIENT ADVISORY & PROJECT SUPPORT

Giving every project a clear direction from the very first decisions.
Our teams support clients in the definition, structuring and management of their projects.
From needs analysis and feasibility studies to technical, financial and administrative assessments, we provide clients with a comprehensive understanding of their project, helping them make informed decisions at every stage. IBI, for example, provides client-side advisory services covering technical, financial and administrative analysis.
Our expertise:
Client Advisory · AMO · Delegated Project Management / MOD · Feasibility · Technical Advisory · Financial Analysis · Project Management · Decision Support
Balancing project ambition with financial control.
Construction economics and cost management are among the collective's long-standing areas of expertise, particularly through Groupe ERM, which specialises in construction cost management and construction-stage project management.
Our teams support projects in defining and controlling their financial framework, bringing together architectural ambition, technical choices, expected quality and budget objectives.
This financial perspective accompanies the project throughout its development, helping anticipate the impact of decisions made during the design and construction phases.
Our expertise:
Cost Planning · Estimating · Construction Economics · Tender Analysis · Procurement Support · Cost Optimisation · Cost Control

CONSTRUCTION COST MANAGEMENT
PROJECT & CONSTRUCTION MANAGEMENT

Turning design into reality.
The success of a project depends not only on the quality of its design, but also on the quality of its execution.
Our teams provide project management, coordination and construction supervision, from the study phases through to final handover.
This ability to oversee a project as a whole helps manage interfaces between stakeholders, schedules, financial considerations and the quality of execution. ERM's services notably include DET, AOR and OPC, with support extending from feasibility studies through to project delivery.
Our expertise:
Construction Management · Site Supervision · DET · OPC · AOR · Coordination · Project Delivery · General Contracting
ENGINEERING THE STRUCTURES THAT MAKE AMBITIOUS PROJECTS POSSIBLE.
The Engineering Group brings together extensive expertise in concrete, timber and steel structural engineering, supporting both new-build developments and complex refurbishment and rehabilitation projects.
This multi-material expertise lies at the heart of STEBAT's capabilities and is also represented within ABAC. ABAC's expertise includes the definition and calculation of concrete, timber and steel structures across design, execution and technical assessment.
Our engineers work from structural assessment and design through to execution studies, developing solutions adapted to the architectural, technical and construction constraints of each project.
Our expertise:
Concrete · Timber · Steel · Structural Assessment · Structural Design · Calculation · Engineering · Execution Studies · Refurbishment · Technical Expertise

STRUCTURAL ENGINEERING
BUILDING SERVICES ENGINEERING

MAKING EVERY BUILDING A COHERENT, HIGH-PERFORMING SYSTEM.
The companies within the collective provide comprehensive expertise in the design and integration of building technical systems.
Heating, ventilation, air conditioning, plumbing, sanitary systems, electrical engineering and low-current systems are considered as an integrated whole, taking into account building use, architecture, comfort and performance requirements.
ABAC's capabilities include electrical and fire safety engineering, HVAC, plumbing and sanitary systems, water treatment and external utility networks. IBI specialises in climate engineering, building services, ventilation, electrical engineering and low-current systems.
Our expertise:
HVAC · Heating · Ventilation · Air Conditioning · Plumbing · Sanitary Systems · Electrical Engineering · Low-Current Systems · BMS · Building Automation · Utility Networks · Water Treatment · Swimming Pools & Spas
ENGINEERING TODAY FOR THE PERFORMANCE OF TOMORROW.
Energy performance has become an integral part of both the design and transformation of buildings.
Our teams work on new-build and existing assets to analyse, simulate and optimise energy and environmental performance.
IBI specifically supports projects focused on energy and environmental performance and works across construction, refurbishment, modernisation and energy optimisation. ABAC also provides energy feasibility studies, thermal calculations and dynamic thermal simulations.
Our expertise:
Thermal Studies · Dynamic Thermal Simulation · Energy Performance · Energy Optimisation · Photovoltaics · Energy Audits · Energy Refurbishment · Environmental Analysis

ENERGY & ENVIRONMENTAL PERFORMANCE
FIRE SAFETY ENGINEERING

INTEGRATING SAFETY FROM THE EARLIEST DESIGN STAGES.
Fire safety systems form an integral part of the collective's technical engineering capabilities.
Our teams provide fire safety system design and coordination, integrating regulatory requirements and interfaces with other technical disciplines from the earliest stages of the project.
ABAC notably provides expertise in low-current electrical systems, fire safety systems and fire safety system coordination.
Our expertise:
Fire Safety Systems · Fire Safety Coordination · Smoke Extraction · Technical Interfaces · Regulatory Compliance
TECHNICAL COORDINATION & DESIGN INTEGRATION
BRINGING EXPERTISE TOGETHER.
The more ambitious a project, the more important the management of technical interfaces becomes.
The complementary nature of our disciplines allows us to bring together the different dimensions of a project: architecture, structure, building services, energy, cost and construction delivery.
Our teams can contribute to the coordination of execution studies, management of interfaces between disciplines and technical design integration. ABAC's services notably include execution studies, interface management and technical coordination.
This cross-disciplinary approach helps identify constraints earlier, facilitates decision-making and contributes to a more coordinated and efficient project delivery process.

A TEAM BUILT AROUND YOUR PROJECT
The Engineering Group does more than bring expertise together: it brings the right expertise together around each project.
Depending on the nature, scale and complexity of each development, the relevant capabilities are mobilised to create a project-specific team with a shared understanding of its technical, financial and operational challenges.
From the earliest strategic decisions through to final delivery, this collaborative approach enables expertise to be combined, interfaces to be anticipated and clients to benefit from a more comprehensive understanding of their project.
