SIENA - Specialist Engineering Consultancy

Expertise

SIENA specialists use their expertise to design comprehensive, effective and feasible strategies and to create technical, practical and reliable solutions.

Fire and life safety

We are here to provide our clients with the best practical, logical and robust advice, drawing on our in depth knowledge of various international and local codes and standards, proven expertise in large and mega scale projects, and extensive experience working with diverse authorities.

Life safety is not optional. It is essential. We help you meet all minimum required life safety standards to ensure your project is compliant, secure, and resilient.

Our experienced Engineers work thoroughly to provide our Clients with the best fire protection design and suitable advice.

Our Specialists in this field adapt the appropriate systems in each project based on a full case evaluation.

Our engineers are experts in assessing and designing effective smoke control strategies to protect occupants from smoke exposure, support firefighters in their rescue and containment efforts, and minimize property damage.

We are proficient in adopting creative, flexible, and trusted solutions in order to deliver a comprehensive and coherent FLS strategy while preserving the Client’s vision and design intent.

We assess and develop the holistic fire safety for project sites, ensuring that fire department access and all fire protection provisions are fully aligned with international and local codes, and Civil Defence guidelines, to provide a compliant, safe, and well-coordinated site layout.

The right level of fire protection starts with accurate hazard and commodity classification. We help identify the fire and explosion risks associated with the materials stored, used, or processed in your facility, ensuring the correct level of protection and compliance from the start.

Our experts conduct well-curated risk assessments to identify unusual hazards and evaluate the risks they may pose, providing you with tailored recommendations for effective fire protection and regulatory compliance.

We have proven experience in these types of projects and understand that every existing building presents unique challenges. Our approach ensures each issue is addressed thoughtfully to minimize design changes and effectively navigate the restrictions and constraints specific to each project.

We manage all the coordination, submissions and approvals related to Civil Defense or any other Authority Having Jurisdiction.

Modeling AND simulation

We apply advanced modeling tools to predict and evaluate FLS performance under real-world conditions to deliver critical insights that inform design decisions, strengthen risk assessments, and facilitate regulatory approvals.

CFD Simulations

Perform advanced analysis of smoke spread, heat transfer, fire growth, temperature and thermal radiation, and suppression system performance to assess fire dynamics.

Pressurization & Ventilation

Design and validate stairwell and lobby pressurization systems, while analysing HVAC and airflow interactions under fire conditions to ensure smoke control, safe door operation, and tenable escape routes.

Tenability & Exposure

Assess toxic gas concentrations, heat exposure, and other life safety criteria to evaluate occupant survivability during fire scenarios.

Evacuation Modelling

Use Pathfinder tool to simulate occupant movement and evacuation times, validating FLS strategies and optimizing egress design.

Acoustic Services

Working with our specialized acoustic consultant, we address all aspects of noise and sound control to deliver a fully compliant, high-performance project that meets international and local acoustic standards.

External Noises

Develop and propose effective strategies to minimize the impact of external noise sources on the project, such as aircraft routes, road traffic, and nearby technical facilities, ensuring compliance with acoustic standards and maintaining a comfortable indoor environment.

Internal Noises

Provide recommendations for controlling internal noise to create highly comfortable indoor environments, considering factors such as wall, door, and slab types, structure-borne sound, as well as noise generated from mechanical and electrical systems.

Rooms Acoustic

Specify the types, absorption coefficients, and percentage coverage of interior finishes to be applied in various areas of the project, ensuring that each space meets the required acoustic performance criteria.

Door Hardware Study

SIENA Hardware Specialists provide a comprehensive door hardware design study aimed at selecting the most optimal door opening solutions.

Specifications Writing and Materials Assessment

Our Specialized Material Engineers utilize knowledge of construction products, materials, and methods to write Specifications for a variety of complex building types.

Bill of Quantities

Our BOQ services align the needs of both Design Consultants and Contractors, ensuring precision and reliability.

“Every day is a new learning opportunity that we must use well to elevate our knowledge and thrive in everything we do.”

Trainings and Seminars
