THE ROLE OF THE ENGINEERING GEOLOGIST

THE ROLE OF THE ENGINEERING GEOLOGIST IN CIVIL ENGINEERING PROJECTS, AND ESPECIALLY ROAD BUILDING, IS DISCUSSED, FIRST WITH RESPECT TO SPECIFIC TECHNICAL AREAS AND THEN IN REGARD TO HIS TRAINING, THE NATURE OF HIS WORKING RELATIONSHIP WITH PROJECT ENGINEERS, AND HIS STATUS IN CIVIL ENGINEERING PROJECTS. THREE AREAS OF APPLICATION ARE ACCORDED SPECIAL ATTENTION: TERRIAN EVALUATION, MATERIALS STUDIES, AND SITE INVESTIGATIONS. IN THE FIRST, A MAJOR CONTRIBUTION OF THE ENGINEERING GEOLOGIST IS LOCATION OF USEFUL LOCAL MATERIALS. PARTICULAR STRESS IN THE SECOND AREA IS LAID ON THE DISTINCTION BETWEEN TESTING MATERIALS FOR THEIR PRESENT PROPERTIES AND FOR THEIR DURABILITY. FOUR EXAMPLES (DOLERITE ,SANDSTONE, SHALE, PEDOGENIC MATERIALS) ARE TREATED BRIEFLY TO SHOW HOW GEOLOGIC EVIDENCE CAN SOMETIMES GIVE MORE TRUSTWORTHY GUIDANCE ON DURABILITY THAN MECHANICAL TESTS AND PLASTICITY INDEXES. SEVERAL EXAMPLES OF THE ENGINEERING GEOLOGIST'S ASSISTANCE IN SITE INVESTIGATION ARE GIVEN, EMPHASIS BEING ON MORPHOLOGICAL FEATURES AND ON CONSISTENCY, POTENTIAL VOLUME CHANGES, AND PERMEABILITY IN DESCRIBING SITE MATERIALS. THE ROLE OF THE ENGINEERING GEOLOGIST CHANGES WITH PROJECT STATUS: AT FIRST HE IS LINKED CLOSELY TO DESIGN DEVELOPMENT, THEREAFTER HE COLLABORATES MAINLY ON AN AD HOC BASIS AND IN AN ADVISORY CAPACITY SUBORDINATED TO CIVIL ENGINEERING CONSIDERATIONS. THE CHARACTER TRAITS NECESSARY FOR THESE ROLES ARE DISCUSSED, ALONG WITH THE SPECIFIC KINDS OF TRAINING, KNOWLEDGE, AND EXPERIENCE DESIRABLE IN AN ENGINEERING GEOLOGIST.
