Heavy Civil Historical Preservation > Our Expertise > Heavy Civil > Historical Preservation Projects which require historical preservation measures offer a means for a community to remember its past, while repairing culturally significant infrastructure/assets. Such projects require much attention and care, as several elements of the facility are likely to be preserved and/or restored. Planning and executing the work can be extremely difficult, as such facilities may lack as-built documentation – a possibility the Owner and contractor must anticipate as it could affect project budget and schedule. Furthermore, in cases where the rehabilitated asset must meet a new level of service, the owner must also consider how the intended function of the improvements may impact aesthetics – a delicate balance. Kokosing’s experience with such projects range from early period viaducts to the Reflecting Pool connecting the Lincoln Memorial to the Washington Monument in our National Mall.
