Verify existing horizontal and vertical control network by checking benchmarks with outside local survey monuments. Establish new horizontal and vertical control network, and tie it to existing network if applicable. Tie horizontal control to local survey datum as described in Art.1.2.6.a. Tie vertical control to local survey datum as described in Art.1.2.6.b. Show all horizontal and vertical locations with respect to the plant grid system and the plant vertical datum, respectively. 2.2 Limits of Work Drawings: 2.3 Deliverables Provide deliverables required in Section 5.1 of this Practice plus the following: Control network sketches Control network drawings Others: 2.4 Schedule Page 2 of 5Process Industry PracticesMay 2002PIP CVS02005 Topographic and Plant Surveys Specification3.0TOPOGRAPHIC SURVEY 3.1 Work to Be Performed 3.1.1 Provide complete horizontal and vertical locations and description of all natural and artificial surface features described in Section 6.5 of this Practice.
