Case Study: In-Situ Truss Reinforcement

There is sometimes a misconception that routine engineering projects require plug-and-play solutions. However, in our experience, even these often present situations that require creativity.

For example, one of our Automotive and Manufacturing clients is expanding an existing line. In order to expand the line, existing trusses and jack trusses require reinforcement in order to install an extension to conveyors hung from the trusses.

Our structural designers have developed an in-situ reinforcement solution in order to simplify the design and avoid removal of loads prior to reinforcement. The design also reduces the total weight of steel required to reinforce the trusses.

Where reinforcement is required for the existing truss members, the solution calls for the design a new member cross section (existing plus reinforcement) without consideration for existing member stresses. As allowed by strength design, it is assumed the new section is capable of developing the full plastic capacity of the new built up member cross section. This assumes adequate connection of the reinforcement and not decreasing the radius of gyration to less than 85% of the existing radius of gyration.

The expansion is moving forward and this solution has saved the client cost and hassle. Furthermore, while this method of reinforcement is now […]

Encouraging a safety mindset – “Be Smart/Be Safe”

“Safety Culture” has become the go-to phrase for most safety programs in today’s businesses. But at what level is a “culture” operating, and how is it maintained? At R.E. Warner & Associates, we believe that safety is not just something to be thought about during work hours, but a continuous mindset that should be part of daily life – whether inspecting a boiler furnace duct on a cold winter day or grilling steaks with family and friends on a hot summer evening.

Being smart about safety entails more than taking a test once a year and knowing the ABCs of basic safety. It is about understanding the present dangers involved in the work or activities you are about to engage in, and what tools should be available to successfully and safely complete your endeavor. We advocate for always being aware of your environment, including the actions of other people around you, and always having a plan for emergencies should something arise that puts you or others in harms’ way.

To encourage a safety mindset, our firm has 21 mandatory training courses, with another 38 additional project- and discipline-specific training programs. We work with third party qualifiers like Avetta, Gatefeed, and ISNetworld […]

    Construction Zones: A Look at How Traffic Maintenance Plans are Determined

Construction Zones: A Look at How Traffic Maintenance Plans are Determined

Ah, summer in Northeast Ohio. The season may be winding down, but construction will be going strong until the cold weather moves in. Of course, we all collectively groan when the orange barrels pop up along the routes of our commutes, but we engineers would like to reassure the public that we do our best to balance safety with minimizing the disruption to traffic in construction zones. We don’t like traffic jams either!

Here’s a look at how we go about forming a Maintenance of Traffic Plan for a construction project that impacts roadways/highways:

The primary function of temporary traffic control is to provide for the safe and efficient movement of vehicles, bicyclists, and pedestrians through or around temporary traffic control zones while reasonably protecting workers and equipment. The additional objective of the temporary traffic control is the efficient construction and maintenance of the roadway or highway.

In conjunction with the Ohio Manual of Uniform Traffic Control Devices (OMUTCD), all temporary traffic control must conform to ODOT’s minimum standard for all traffic control devices used during construction, maintenance, and utility activities plus incident management.

Every work zone situation is different, so several items must be considered in determining the traffic control needed. Questions […]

    Understanding Levels of Development in Building Information Modeling

Understanding Levels of Development in Building Information Modeling

More is Not Necessarily Better

As Building Information Modeling (BIM) becomes increasingly utilized in our day-to-day work, it is increasingly apparent that there is a need to better explain the Levels of Development (LOD) to which a model can be created.

When a client requests a model, it is on us as the consultant to ask what the intended use will be and from there make a recommendation as to which LOD the model should be created. More detail is not necessarily better. First, the higher the LOD, the more cost the client will incur – we do not want to spend additional time modeling elements above the desired level. Second, the higher the LOD, the larger the computer file. Large model files become more burdensome on computer resources and can be unusable by the client.

Ultimately, we want to develop a model at an LOD where all the necessary information is available, but there is no extraneous detail that has driven up the cost of the project and/or made the file size unwieldy. Sometimes this may mean creating the overall model at a lower LOD but drawing certain elements or areas of the model at a slightly higher LOD. For example, […]

    Service Garages: Thinking Through Specifics to Ensure Successful Design

Service Garages: Thinking Through Specifics to Ensure Successful Design

Today we’re going to talk about services garages. While some may consider these bland, unexciting buildings, they are actually highly important, unsung heroes of municipal infrastructure. They operate in the background, commanding little attention, yet facilitating critical functions. In the event of a potential calamity such as a snow emergency or water main break, these facilities allow maintenance personnel to respond quickly and effectively, so that residents and workers can continue to go about their business.

What’s more, not one is like another. Having completed over 20 of these buildings in the last 15 years, we understand that while they may all have similar components, the ways in which they are specifically designed are vastly individualized. Thinking through these specifics is crucial to success.

Without further ado, here’s a look at the “what” and “how” of service garage design.

First, let’s go over the usual pieces and parts of these buildings. The average service garage may have:

Storage

Cold
Bulk
Maintenance – general or specific

Maintenance Bay(s)
Wash Bay(s)
Operations Support

Locker rooms
Laundry
Break room
Offices
Storage

Back-Up Power
Access controls

That’s a fairly short list and it looks pretty simple, but if we do our jobs right during the discovery and assessment phase of a service garage project, the actual design becomes much more involved […]
