structural ENGINEERING DESIGN

Our licensed professional structural engineers combine structural analysis with experience and knowledge to create structural engineering designs that meet Ontario Building Code and project requirements. Our licensed professional structural engineers also prepare drawings indicating the location, sizes and quantities of materials, and specifcations indicating the quality of materials and required performance of structural systems.

Our well experienced licensed professional structural engineers provide innovative and cost-effective structural engineering design solutions to commercial, industrial, institutional and multi residential projects. Detailed accurate specifications prepared by our licensed professional structural engineers with decades of experience, reduce or prevent unexpected additional costs.

Our licensed professional structural engineers prepare required stamped structural engineering for
Foundation Designs including Pre-engineered Building Foundations
Retaining Walls
Structural design for Office Buildings, Commercial Retail Buildings, Restaurants, Gas Station Canopies, Low Rise freestanding Industrial Buildings, Multi-Storey Apartment Buildings

Our licensed professional structural engineers also provide design services for building components such as stairs, miscellaneous metals, non-load bearing walls, steel member connections, timber connectors, light gauge steel con-nection details and metal stud back-up to veneer walls.

Our licensed professional structural engineers use state of the art technology including STAAD PRO software.

Our licensed professional structural engineers' typical structural engineering work includes:
Design of the primary structural system for gravity and lateral loads;
Design of proprietary components to be incorporated into the primary structural system;
Design of secondary components not part of the primary system but requiring inherent structural integrity, such as
cladding systems, roofng systems or balcony railings;
Review of shop drawings; and
General review of construction as required by the Building Code, with the plans and other drawings that form the basis for the issuance of the permit

Our licensed professional structural engineers work with the clients and the design/build contractor to define a scope of work that enables them to provide the required designs, specifcations, contract documents, and/or contract administration and applicable codes and standards—especially where they affect the structural integrity of the building.

While incorporating the requirements our clients, our licensed professional structural engineers
• abide by the requirements of the current applicable codes, acts and regulations, usually includes, but is not limited to, the National Building Code of Canada; National Building Code structural commentaries; the Ontario Building Code; CSA standards,as appropriate; and publications and design guides from trade associations such as Canadian Institute of Steel Construction (CISC), The Canadian Sheet Steel Building Institute (CSSBI), Canadian Portland Cement Association (CPCA), Canadian Wood Council (CWC), Canadian Prestressed Concrete Institute (CPCI),etc
• establish the loads and structural resistance for the structural design; and
• recommend any specialized services related to the structural design process that are required for completion of the project.

In preparing final plans and specifcations, our licensed professional structural engineers

e) cooperate with others in their preparation of cost estimates and schedules from time to time, based upon the most accurate information available as the design develops; and
f) advise the client and/or the general contractor that structural elements designed by others are to be designed by engineers according to specifications and Ontario Building Code requirements

In the design development stage, the selected preliminary design is developed in suffcient depth to complete construction details and permit work on construction documents to begin. During this stage, our licensed professional structural engineers,
a) attend meetings with the client and other stakeholders to coordinate the flow of design information amongst the other design team members;
b) cooperate with the other stakeholders, responding to their requests, taking into account their requirements, and advising them of functional aspects of the primary structural system that may affect the design of their components;
c) analyze and design the structural system in conformity with applicable codes and regulations;
d) review serviceability limits, such as: defections, vibration, lateral drift, concrete and masonry crack control, foundation settlement and soil-structure interaction;
e) review reports by specialized services such as geotechnical, vibration analysis and wind tunnel testing, and incorporate recommendations into the primary design;
f) prepare structural analysis and design calculations for the primary structural system components;
g) prepare foundation designs based on recommendations in the geotechnical investigation report;
h) prepare the framing design and design detail sketches showing layouts of typical areas
i) prepare or edit outline specifcations for structural components; and
j) coordinate the structural design with defection and lateral movement criteria to meet requirements of other specialty engineers.

In conjunction with designing the primary structural system, our licensed professional structural engineers, with respect to primary structural elements, connection details and proprietary products:
specify types of elements, their positions within the structure and methods of connecting to the primary structural system; and
determine and specify in the contract documents the elements that are to be designed by other specialty engineers, and specify loads and design criteria for use by other specialty engineers in their design.

With respect to non-structural elements attached to the primary structural system, our licensed professional structural engineers
design the primary structural system to accept and support such elements; and
indicate the assumed design loads applied to the primary structural system by the non-structural elements.

Our licensed professional structural engineers prepare calculations to support the structural design of the primary structural system. The calculations should contain a table of contents or index and must clearly show and delineate service loads, factored loads and factored load combinations. The structural calculations should be dated, legible and retained in a project fle. A copy of input and output of computer analysis should be included in the project fle, along with a description of the software used.
