Level readings were first employed in the Houston area by Richard Peverley of Peverley Engineering starting in the 1970’s and proved to be very useful. Level readings can help determine whether a sufficiently great problem exist with the foundation or upper story framing to warrant structural repairs. They help put damage, such as cracks, into the proper perspective by quantifying the slope of the floors and thus giving some objectivity to the judgement as to whether repairs are needed. Since the vast majority of houses have been built within certain construction tolerances it is not especially difficult to tell whether much movement has occurred since construction in most cases. We put the levels obtained during the inspection on a scale drawing(s) and this is provided to the clients for reference.
A scale drawing is necessary should foundation repairs be needed since piles or piers must be laid out with certain maximum spacings to be effective. Also, scale drawings enable upper story sags to be compared with the building code allowable sags for spans so that the need for repairs can be judged. Level readings can also help determine if the foundation repair contractor has properly lifted the foundation as close as possible to its original position. If foundation repairs have been carried out properly the level readings will serve as an independent baseline for warranty purposes since most contractors do not provide these to the homeowners. If no foundation repairs are needed, the levels readings serve as a reference by which to judge future movement or stability. This is especially important when buying a house which has been constructed more unlevel than it should have been or one that was not properly leveled during foundation repairs. Stability over time will help reassure future buyers about the acceptability of the foundation –Read More about our services
