What is Contingency and How Does it Benefit Construction Management?

The word “contingency” has many different meanings, depending on the industry you serve or your point of view. In construction, contingency refers to a percentage of money reserved to cover unanticipated project costs. A contractor, an owner, or a design professional (aka architect, engineer, etc.) all likely feel that the proper use of contingency within a project stems from different, but justifiable causes.

Design professionals

For instance, a designer undoubtedly assumes responsibility for planning and designing a building that complies with all building codes and regulations. However, to draft a complete project that indicates every possible section or detail, and also encompasses every possible combination of material, model, or manufacturer is inconceivable. Therefore, in the designer’s eyes, it may be perfectly acceptable during the construction phase to use contingency spend to accommodate variations or updates that need to be made to the “as-bid” plan set.

Owners

In contrast, if an owner is fortunate enough to have any contingent funds left in their budget, they are likely to prefer that they are used on project betterments. Perhaps to add items to the project that had been eliminated during design or value engineering, or maybe just to incorporate items from their wish list that hadn’t made it into the project initially. It is conceivable to see the justification for this case as well.

Contractors

Lastly, a contractor may take the stand that the use of contingent funds is reserved for unforeseen or differing conditions than those outlined in the plans and specifications from which they based their bid on. For example, old foundations or utility piping buried on a project site that wasn’t documented on the as-builts (record drawings) of a particular property. The contractor had no way of knowing the subsurface conditions of the entire project site and therefore should be entitled to additional compensation, drawn from the project contingency. It seems fair to me…I may, however, be biased.

Whatever your viewpoint, one thing is clear. Every project should have some measure of contingency included and its acceptable uses defined and agreed upon at the onset, you’re going to need it!

School Bond Referendums: 6 Essential Success Factors

More than ever, communities must produce smarter tactics to promote school bond referendums. Failing to do so will result in a lack of voter support and an unsuccessful bond initiative. While there are no guarantees, a positive outcome is much more likely to occur when an organized, thoughtful approach is in place.

6 Essential Success Factors to Garner More “Yes” Votes

  1. Build trust – The relationship between the community, board of education, administration, faculty, and staff is crucial. The connection must be sincere and built up over time. As we know, the existence of trust does not promise success but the absence of it might indicate defeat. Without trust, the chance of a vote failure is high, no matter what other action takes place.
  2. Listen to stakeholders – Understand the needs of every stakeholder group and include them in the planning process. Appropriately involve them as the initiative advances and keep in mind two-way communication is critical. Consider launching regular surveys to understand the goals of community members and act on the feedback when you get it. After all, investing time to collaborate with the community will pay off.
  3. Personalize the message – You will need to do some selling to gain support. First, learn about the different groups that make up your district. Then, understand what they need to know about the school bond referendum based on their goals, priorities, and interests. Thus, it will be easier to develop specific messages that appeal to their interests and priorities. Reflect on the unique needs of each group you are trying to reach.
  4. Use numerous styles of communication – Ignoring critical channels of communication could potentially make or break the campaign. Present your message on local news media outlets, direct mail, social media, and face-to-face to influence all stakeholders. Answering people’s questions, addressing their concerns, and keeping them informed throughout the process is key.
  5. Community groups – Often, it’s small community groups that do the most effective selling. They represent the stakeholder groups. The individuals who live amongst and regularly engage with voters have the best chance of connecting with people in a personal way. Contemplate capitalizing on these community groups and encourage them to host neighborhood meetings. Intimate Q&A sessions are a proven way to build community understanding and support.
  6. Public information meeting – Consider holding a public information meeting at the school. Think about organizing the event with each table representing a specific facet that may interest stakeholders; education, finance, building, superintendent, the board of education and PTA. This way community members can walk around and pursue targeted information. The individuals at the tables must be effective in leading one-on-one conversations. This added touch carries a sense that every question is important and will contribute to overall voter turnout.

Securing School Funding Requests

A successful school bond referendum campaign is not the result of the final push. To be effective, you must start from day one crafting the message and fostering support. It’s all about the way you communicate. Trusted relationships and an informed community are keys to a winning outcome.

10 Reasons Why You Need BIM on your Next Project

Michael Johnson | Director of Integrated Design + Technology | Bush Construction

BIM (Building Information Modeling) is a 3-D modeling technology. It allows contractors and owners the opportunity to virtually build, visualize, coordinate and troubleshoot before a shovel ever hits the ground.

  1. BIM provides a facility that was built virtually before it was built physically.
  2. BIM will point out any conflicts between structural components and architectural items.
  3. BIM eliminates problems—no more accidentally slamming through plumbing pipe.
  4. BIM provides all parties involved with a high level of confidence that what is being built will work.
  5. BIM means less re-work.
  6. BIM significantly reduces waste. Construction creates 53.4 million pounds of waste per year, not including demolition.
  7. BIM assures greater efficiency.
  8. BIM provides owners with a more in-depth understanding of their building.
  9. BIM opens doors to using more advanced technologies, such as virtual reality and laser scanning.
  10. BIM expands documentation. It provides the opportunity to communicate and make quicker, more informed decisions

BIM utilizes the latest technology to merge physical and digital, allowing Bush Construction the ability to provide our clients with the best construction experience possible.

Cement Soil Stabilization

Location: Lujack’s HiLine – Audi, Mercedes-Benz, Porsche, Volkswagen

Kevin Mericle | Superintendent | Bush Construction

Why Cement Stabilization?

Cement stabilization is required when the soil on a construction site needs to be amended. This process allows the installation of the building pad on site before the cold temperatures and ground freezing of winter sets in.

At one of our new construction sites, Lujack Hiline – a high-end car dealership in Davenport, Iowa, a geotechnical engineer recommended we proceed with cement stabilization. It was no surprise – we could not drive our vehicles on the site without sinking. We were aware, after a very wet September, that we were going to be facing poor soil conditions. Unfortunately, there was no way for the soil to self-correct on this site since as we would not have been able to get the soil to compact before winter began. The ground just wasn’t hard enough.

While this predicament is fairly common for this portion of Scott County, we don’t have to use this method often. In this area, we generally hit moisture at 6-7 feet down. On many job sites, we may hit pockets of poor soil, but on the Lujack’s site, the entire 4-5 acres was moist. The site was much too large to core out and fill with rock like we can on smaller jobs. Together with the owner, we made the decision to move forward with cement stabilization over the Thanksgiving weekend.

What is Cement Stabilization?

Soil stabilization can sometimes be done with lime, but since the temperatures were not warm enough for a long enough duration, this was not an option for this situation. Cement would need to be the cure.

Cement stabilization is the improvement of a soil material through the addition of a cement binder. The goal of stabilization is to improve soil for construction purposes. The most common method involves incorporation of small quantities of binders (cement) to the aggregate.

On the St. Vincent Athletic Complex football field project, we ran into a similar situation and were able to amend with lime. Lime is laid layer by layer and you can see the difference in color. We rototilled the lime in and then rolled it over. The process took two days for each football field. The lime was brought in from our sister company, Linwood Mining; truck after truck. Just like at Lujack’s, the ground wasn’t stable, and we couldn’t guarantee the fields without stabilizing the soil.

At Lujack’s we chose the cement process as it was recommended by the geotechnical engineer, it was weather appropriate and it was the most cost-effective option. Cement stabilization requires only one layer, but air temperature is key. The temperature must be 40 degrees or higher for the stabilization to set appropriately.

How does Cement Stabilization Work?

Since we do not have a local company that performs cement stabilization, we hired McCleary from Decatur, Illinois. They set 200 lbs. of cement every three feet. The machine itself costs $800,000. Also, on site was a tiller and two trucks. The two trucks each weighed over 15,000 lbs. McCleary remediated 170,000 SF in two 12-hour days. If we had decided to core out and fill the site with rock, it would have taken at least two weeks and we would have needed to find a place for 1,000 truckloads of spoils.

The cost to stabilize the soil ran approximately $200,000. If we had filled with rock, the cost would have been around $300,000. A savings of nearly 33%.

The cement stabilization was a success and construction is in full-swing.
