Structural Systems:• This section contains information on the structural elements of the building.Foundation Systems:• This section contains information on the building foundation system.• If the foundation is stepped or sloped, and the configuration is known from thedrawings, this is briefly described in the Comments section.• Known soil bearing capacities, pile capacities, or other geotechnical informationare described, and the source of the information is stated (e.g., general notes ofdrawings).• Analytical assumptions related to the settlement analysis are listed forfoundations or portions of foundations (i.e. pile depth) which are unknown.• The elevation datum is taken as NAVD88.Exterior Finishes:• It is noted if the exterior finish system is a veneer or if it is load bearing (ifknown).• It is noted if control joints are present and visible.• It is noted if drawings indicate the method of anchorage of the exterior finishesto the structure.Interior Finishes:• The emphasis is placed on noting and commenting on brittle finishes that mightbe affected by building settlements.• Typical finishes representing general conditions observed are listed, but may notrepresent all finishes present within the building.• When describing interior finishes, the distinction is made between gypsum wallboard and true lath-and-plaster wall finishes (if known), because lath-and-plasteris more sensitive to building settlements than gypsum wall board.Significant Unknown Structural Conditions:• This section records structural conditions that the engineer was not able toobserve, or that do not appear on existing drawings, but that are important tounderstand the vulnerability of the building to settlement damage. Examplesmight include unknown foundation type, unknown method of attachment ofterra cotta veneer, or the inability to access important areas of the building suchas the basement or crawl space during the walkthrough.Comments:• Information is included here for utilities, areaways, drawings reviewed, andadjacent buildings, where known.• If a structure contains two or more building numbers as assigned by theWashington Department of Transportation, it is noted in this section.
