Structural – While older structures were generally made out of historically stronger, more long lasting materials, over the course of time, they may have become structurally un-sound, or in some cases, unsafe for the building's inhabitants. Adaptive reuse projects could potentially encounter a variety of structural issues. For example, timber frames and unreinforced masonry may have been acceptable options for load bearing walls but modern building codes require steel reinforced beams, ties, and connections. Cinderblocks, bricks, mortar, and timber cannot stand up against events such as earthquakes and this can cause a great threat to human safety. While there is significant cost, it is possible to bring this structure up to modern standards by fixing the building to its foundation, tying building elements (such as roof and walls) to each other so that the building moves as a single unit, attaching walls more securely to underlying supports so that they do not buckle and collapse, and bracing or removing parapets and other unsecured decorative elements.

Infrastructure – Even if your structure is sound, your infrastructure will likely be in need of an upgrade. A building's infrastructure life span is typically 30 years and most adaptive reuse is done on buildings whose electrical wiring, plumbing, sewer and sanitary lines, ventilation ductwork, and other essential operating systems are that age or older. In addition to upgrading existing systems, brand new systems may need to be added (like air conditioning, fire suppression, information technology, and security). Converting an industrial warehouse into high end loft apartments frequently results in an entirely renovated infrastructure to accommodate much different needs-simple functions such as heating, air conditioning, indoor air quality, and plumbing may require drastic reconfiguration. Outside of the building itself, there are infrastructure needs that must be addressed. For example, ensuring there is adequate water for sewer, sanitary, and fire suppression lines or sufficient power from utility lines that will be needed to service upgraded electrical and mechanical systems. Upgrading these may be pricey, but if the cost and time for testing, evaluating, and permit acquirement is accounted for in the pre-construction stage it will be much less of a headache during your redevelopment project.

How are these remedied?

As is inherent with adaptive reuse projects, upgrades to meet current codes and specifications will be necessary. The key to mitigating these potentially deal breaking issues is to plan ahead and anticipate issues before you start. Devising a solid pre-construction/design plan that allows for the addition costs and time considerations, you can avoid construction halting issues that may arise as you get into your project. Combining the functionality of a brand new structure, with the charm and character of a historic building, can frequently result in a creative, one of a kind project that will bring new life and a new use to its community.
