How Value Engineering is Being Used in Rooftop Applications
Value engineering refers to an organised effort aimed at analysing material selection, equipment, systems, and features to improve performance through cost reduction or increase without sacrificing performance. This concept first appeared in the mid-1900s and has seen significant improvement over the years.
Experts have established that durability and functionality are two factors that should be prioritised in order to create value. Prioritising durability and functionality in commercial roofs is vital to extend the roof’s expected lifespan. Therefore, you’ll have amortised the roof’s cost over a longer period hence creating value.
Relevance of Value Engineering
Most of the value engineering concepts developed in the mid-1900s have no impact in today’s world. However, the relevance of value engineering in roofs is still appreciated by workplace managers and building owners. This concept is exceptionally prevalent in the construction industry. Today, for instance, roofing contractors use value engineering concepts to determine the target cost of a roof.
To pursue this concept, however, requires careful consideration to avoid getting in trouble. If a manager or owner approves the substitution of materials within the concept of value engineering, they should be able to maintain or improve the current company performance at a lower cost. Failure to establish the right substitution or requirements may result in the delivery of low performance products at a lower cost. While your materials may be much cheaper at the outset, structural failures and maintenance costs may be very costly.
When choosing a value engineering model for your building’s roof, ensure to stay up-to-date with the process to avoid any surprises with materials you hadn’t vetted. Consider installing the right fall protection system, such as a barrier for flat roof, for your safety while on the roof.
Durability and Functionality in Roofs
How does durability and functionality ensure the cost-effectiveness and longevity of roofs? Well, it all has to do with safety and maintenance. Functional roofs are usually safer to maintain and durable roofs hardly crack and break. Below are examples of value engineering trade-offs known to provide a reduced cost without sacrificing the durability of your roof.
1. Replacement of Tapered Insulation with Additional Drainage
Additional drainage can be a great idea to get rid of pooling water, which is a huge cause of concern, especially for flat roofs. Tapered insulation can help shed excess water on the roof. It can prove to be a less costly option since it will eliminate any pounding that can be promoted by the lack of tapered insulation.
2. Replacement of Adhesives with Fasteners
For any commercial roof, an adhered roofing membrane is the most durable and safest option. The replacement of adhesives with fasteners can make roofs almost as durable and at the same time offering key trade-offs. However, the fasteners usually penetrate the insulation layer which may make the roof less efficient when it comes to heating and cooling. This can also make the roofing membrane susceptible to impacts.
3. Change in the Construction Details
Changing the construction techniques in roofing can have a significant impact as the materials themselves in terms of cost. For instance, you can install counter-flashing in two parts instead of a single-piece counter-flashing. This can be less costly and doesn’t sacrifice the durability of your roof in the long run.
