The document contains field notes from a leveling and tachometric surveying exercise. It includes: - Leveling readings taken along a route to determine reduced levels at stations. - Tachometric staff readings taken from an instrument set up to survey cross sections of a bridge and sections upstream and downstream. - Horizontal distances, vertical distances, and reduced levels were recorded at points along the cross sections.
