Systems Analysis

Residential Services

WSM Engineering is specialized in mechanical and electrical designs for custom homes, renovations and new additions for the discerning homeowner with a desire for the highest quality of air circulation and comfort. We provide fast, friendly, professional service for developers, homeowners, architects, engineers, builders, contractors and draftsman. WSM Engineering will be committed to provide the following:

  • We will provide professional plans created using the latest software in CAD technology, preferred by most city and town Plans Examiners over common hand-drawn plans.

  • We will pick up architectural plans and deliver the completed design plans and calculations for your convenience. This is a real time-saver when coordinating large-scale renovation projects.

  • We will provide heat loss/gain calculations so that you can begin to plan for your new or upgraded heating, ventilation and/or air conditioning systems for optimal efficiency.

  • We will carry out on-site job inspections to ensure that implementation of the design is according to the plan specifications. Most designers consider a project completed upon delivery of the design but customers consider a project completed upon implementation and so do we.

  • We will make recommendation of products, manufacturers, suppliers, dealers and general contractors to cater to your needs based on our thorough knowledge of the latest in technology and first-hand experience with the best products and services in the industry. It’s the friendly kind of advice and expertise that you need when dealing with a myriad of technical information.

Our team specializes in mechanical and electrical engineering services both internationally and locally and has successfully carried out complete design and build engineering projects for a number of high rise apartment buildings, seniors’ residences, palaces and meeting halls. Please feel free to browse and view our projects.

Commercial Services
Above all, the commercial sector requires flexible design and efficient use of floor areas. Each square foot used for building services is a lost square foot for leasing. WSM Engineering has considerable international experience, having delivered commercial projects around the world. In order to leave as small a footprint as possible, we recommend our customers consider skid mounted modular mechanical rooms and pump rooms, which are a new trend in the industry with all equipment installed in a factory on the skid. Secondly, we would also recommend energy-efficient systems based on Green Building guidebooks and Hartman Loop technology according to current trends.

At WSM Engineering, we engage in fast-tracked design and effective communication with multinational developers, architects and owners as a key role for our future success in this sector to better serve our international customers.

We provide an integrated design team of mechanical, electrical, lighting, telecommunications and information technology and design engineers, which results in significant advantages to our clients and to our design and construction partners. Whether designing high rise towers or sprawling low rise campuses, WSM Engineering brings innovative solutions that result in improved scheduling, cost efficiency and operational advantages.

The tenant sector has emerged as a result of an industry need for specialized engineering services for the increasingly dynamic commercial real estate market. As companies move from one location to another to accommodate expansion or contraction, or to reposition themselves either economically or geographically, commercial space needs to be redesigned for the changing occupancy levels and layouts.

We will provide dedicated specialized personnel to tenant engineering. We plan to enter into this sector as a result of following a few simple rules: respond quickly, provide total client support, deliver solutions with long-term value and always keep focused on one important end – the client’s peace of mind.

Institutional Services
The varying and often specialized functions required for each institutional project result in unique engineering services. Our response to the interests and goals of an institution is part of the value we bring to our clients. With projects spanning the disparate functions of high security prisons compared with higher learning universities, we work with our clients at all stages of planning to provide a design that meets the current and future needs of the institution.

With a long-term perspective for phased expansion or possibly contraction, our institutional clients require a dependable consultant with a broad vision in design. Recognizing areas for either value engineering or extending the value of the investment, WSM Engineering is instrumental in providing flexible installations that increase the potential for future projects as opposed to restricting them.

Industrial Services
The industrial sector requires a detailed understanding of a facility’s function simply to provide a satisfactory design. WSM Engineering Inc. prides itself in taking the time to properly learn the industrial processes that we will provide engineering services for. We have expertise and take challenges to provide sound infrastructure, knowledge a high quality of service and design improvements in the industrial processes.

This sector not only demonstrates our technical excellence but also our project management aptitude.

Municipal Services
The patron experience is the key element to designing recreation and entertainment facilities. By providing effective lighting and ventilation, as well as introducing cutting-edge technologies in the facility’s design, we improve the overall experience and thus assist in increasing revenues by creating a pleasing facility that encourages customers.

The challenge of creating an exciting and engaging sensory environment depends on thorough knowledge of technological advances and solid experience in effective design principles. WSM Engineering has designed many projects, varying from community centres to stadiums and racetracks. We bring innovative design to our projects while ensuring dependability, flexibility and longevity for the facility’s future.

Health Care Services
With our experience of designing hospitals, we work closely with the client and ensure the best possible design by bringing only the highest level of quality and commitment to each project we undertake. With over 28 years of design experience, we can perform under any directive from a small renovation to a million square foot green field healthcare campus.

As a value-adding design engineering firm, we at WSM Engineering have a long-term perspective having worked with international clients. It is our diverse spectrum of services that result in significant opportunities for improved efficiency, flexibility and serviceability of the facilities we design.
