Cutting Costs on Multi-Unit Projects with ICF Systems

Insulated concrete forms are becoming a common choice for construction projects. Construction teams prefer simplifying complex jobs in several ways. With their design flexibility and ease of use, ICFs are particularly advantageous for multi-unit projects. Whether it’s an apartment building, retail center, office building, or anything else, you get good results with ICF Systems construction.

If you’re new to building with ICFs, look for ways to cut costs on your multi-unit projects. This post explores ways to save money when building multi-unit structures with ICF systems.

Cost-Cutting Strategies For Building Multi-Unit Projects With ICF Systems

Working with insulated concrete forms can be a solution for cutting costs on construction projects. Here’s how ICFs help reduce costs for builders and property owners.

• Easy to Handle: ICF blocks are lightweight and easy to assemble, reducing the need for large crews or specialized equipment. ICFs help builders reduce labor costs on multi-unit projects.
• Integrating Multiple Steps: Each ICF block combines structure, insulation, and formwork into one system. This integration reduces the number of trades and stages required. That is another way ICFs minimize labor costs.
• Energy Efficient: The high R-values and continuous insulation provided by ICFs contribute to significant long-term energy savings. That can make ICF construction a central selling point for building owners or tenants.
• ICF Accessories: Many ICF systems have useful accessories to make processes easier or faster. With the right tools and accessories, builders can save time and money.
• Durable Construction: ICF structures are highly resistant to moisture, pests, and extreme weather. This durability translates to lower maintenance and repair costs over the life of the building.
• Streamlining Projects: Because ICFs allow for faster builds and fewer delays, they help projects stay on time and budget. Fewer scheduling conflicts and fewer budget overruns make them an excellent choice for multi-unit structures.

Develop Standardized Unit Designs

One of the most effective ways to reduce costs on any multi-unit project is through standardization. The more standard the units are, the more repeatable the processes will be. Developing a standard design across units allows you to repeat floorplans, window and door placement, materials, etc. That streamlines processes from the earliest stages through inspections.

When the units are all the same, crews can develop repeatable workflows. That increases speed and efficiency while reducing the potential for mistakes. Additionally, crews will get faster and more efficient as the project progresses. A complex project essentially turns into an assembly line, achieving better results while saving on labor costs.

Focus on Waste Reduction

Minimizing waste is a key component of controlling costs on any construction project. Fortunately, ICF construction reduces waste if everyone, from project managers to laborers, does their part.

Start by ensuring proper storage and handling of forms. ICF blocks can be damaged if exposed to the elements or handled roughly. Construction teams can solve much of this through proper job site management. To prevent damage, create secure storage areas for materials. You may also need to set policies for tracking and handling materials.

Accurate measuring and cutting are also essential. Emphasize the importance of being careful and precise when cutting ICF blocks. Instruct workers to save offcuts so the team can reuse them when needed. Also, consider using accessories like height adjusters to reduce the need for cuts.

Installing Interior and Exterior Finishes

If you’re new to ICF construction, consider installing interior and exterior finishes using traditional methods. While conventional methods may still be an option, you might have a more efficient way to handle these tasks.

Traditional installation methods for mounting finishes on concrete structures require several steps. For example, you might have to hang furring strips, use various anchors, and more. With many ICF systems, the blocks have integrated fastening strips.

The strips inside ICF blocks usually run vertically at regular intervals. They can often provide reliable attachment points for siding, drywall, and fixtures. By locating and using these strips, crews can save time and materials on the job site. These savings can add up fast when working on a large multi-unit project.

Reduce the Concrete Core Where Possible

Reducing the thickness of concrete cores in some areas could be an option for some multi-unit projects. Not every wall is subject to the same loads, so there may be options to switch to thinner blocks. However, structural engineers should guide these decisions. You only want to reduce core thickness if you can do so without compromising structural integrity.

One option is to make the walls on the upper floors thinner than those at the structure’s base. Upper floors may not have the same dead loads as lower floors, so you can use blocks with thinner cores. Interior partition walls or non-load-bearing firewalls between units may not require the same core size as exterior or structural walls. The important consideration is that the walls comply with engineering specs and local building codes.

Interior walls that are just partitions could save money by using a lighter wall system. For example, you could use framed walls for partitions, saving money on concrete and labor.

Use ICF Door and Window Bucks

The door and window bucks offer another opportunity to save on labor and materials. Many builders still choose traditional wood bucks for doors and windows. While these can still serve the basic purpose, there is a solution that could save time and materials.

Many ICF manufacturers have foam bucks designed to fit seamlessly with their wall systems. These bucks fit directly into the wall assembly to create a tight fit. Workers can install them faster than wood bucks, and it saves materials. In many cases, you can even use accessories like Burmon Buck Braces to save more time, material, and labor.

As a bonus, using ICF bucks enhances the structure’s efficiency, resulting in a tighter seal for less air leakage. The ICF foam is also a far superior insulator than a wood buck. It also reduces the additional work of sealing and insulating around the buck. That makes ICF bucks a better solution in almost every way.

Ensure Proper Crew Training

A well-trained crew is essential for maximizing the cost-saving potential of ICF construction. Training should cover block stacking techniques, creating openings for doors and windows, bracing methods, and best practices for concrete placement. Crews should also learn to cut forms precisely and correctly handle materials to reduce waste and damage.

Even experienced workers benefit from ICF-specific instruction. Mistakes in layout, bracing, or pouring cause delays, rework, or compromised wall integrity. Investing in training upfront can prevent those issues and lead to faster, smoother builds.

Selecting the Right ICF System

While ICF block systems have many similarities, there are significant differences. Choosing the best ICF manufacturer can help you maximize efficiency while reducing costs.

Look for block systems that offer components compatible with your project needs. Key factors may include block heights and core sizes. Look for available configurations, or check out the tie design and available accessories. Look for features like integrated fastening strips and pre-formed foam bucks for convenience and additional cost savings.

It’s also smart to engage with manufacturers early in the planning phase. Many ICF suppliers offer technical support, design advice, and training resources. Their expertise can help you refine your plans and avoid costly missteps. For large-scale, multi-unit projects, manufacturers may also provide bulk pricing discounts.
