What is a build out? In construction, build out can signify a couple of definitions. On the one hand it can mean literally expanding or building out from a pre-existing, smaller building. Additionally, build-out construction is often attributed to tenant improvements or TIs. In other words, in a commercial building setting, the owner’s space needs more spacial planning and construction before it is move-in and every-day business ready for an occupant. This can be a new location requiring build-out, or previously used office space to be upgraded.
Technological innovations have aided commercial construction build out techniques in recent years. These techniques reduce costs, timelines and construction changes. There are many modern changes, but here are some of the most common new construction techniques in build outs.
3D volumetric construction uses 3D units produced offsite for modular systems of construction materials. After completion of production, these modules are transported to the building site to be integrated and finished in the building. These units can be built in advance to be sound proof, fire proof, and to have other vital construction properties prior to final assembly.
Precast flat panel modules, or cross-wall construction, are for walls and floors. The panels are manufactured off-site and then are shipped to the site for construction in the building. Even pieces which are load bearing can be produced as precast flat panel modules (including insulation panels). One of the advantages of this is the accelerated construction in the building.
Tunnel formwork system is a construction technique for fast construction of walls or repetitive units. It is made faster by using readily mixed concrete in a productive setting where cranes can stack the formwork.
Pre-cast foundation technique is for building foundations quickly with pre-cast, factory-produced, concrete elements. The result is strong foundations (no matter the construction weather) from joining piles made of concrete.
Hybrid concrete building technique uses the best of concrete pre-casting to quicken the construction process. Even though the process is sped up, quality can actually improve and reduce costs. Building hybrid concrete structures is actually fairly simple.
Flat slab technology uses modern formwork for quick construction of flat slabs for partitioning. These flat slabs can be changed, even below the floor slabs, but require less support than traditional methods. This technique also lowers labor costs.
Insulating concrete formwork technique turns polystyrene blocks into twin walls. This technique is as fast and easy to assemble as wall formwork. Upon assembly, ready mixed concrete is filled into the blocks. This makes the commercial building thermally and sound insulated and the process fool proof.
Thin joint masonry technique for concrete blocks and panels uses less mortar. While less is used, efficiency and speed increases and cost reduces. With these achievements, the quality of the bond is still as strong as with traditional mortar.
New construction techniques in build outs have certainly improved in current times with technology. There are many options to choose from, but some of the most popular include 3D volumetric construction, tunnel formwork system, cross-wall construction (or precast flat panel modules), flat slab technology, pre-cast foundation technique, hybrid concrete building technique, thin joint masonry technique and insulating concrete formwork technique. The result of all of these is to improve quality and speed of construction, while reducing changes and costs.
