Job No: N4667 Sheet No: 01/02 File No: 11111 Project Title: Proposed Iconic Structure For Invent Media Limited At Western Avenue, Surulere, Lagos Location Visited: Western Avenue, Surulere, Lagos Date/Time of Visit: 11 th August 2015/ 2pm till 4:30pm. Purpose of Visit: Inspection Discipline: Structures Weather: Sunny People Met: Mr Kunle and Mr Brown Record of Visit: The following observations were made during our site visits: The surface and edge of the pile cap supporting the billboard was powdered and chalky with aggregates easily chipping off (Photograph 1). This suggests weak concrete platform. We agreed to carry out Schmidt hammer test on the pile cap to determine the structural integrity of the concrete. The two steel girders (Photograph 2) for the billboard and tower (photograph 3 &4) up to 6m height were on site. Welding operations for the back frame of the billboard were on going. Brownish liquid rust stains were noticed in some of the welded joints . This suggests possible defects in the joints. Mr. Kunle, however, assured us that special electrodes were being used for the joints and that the defects will be corrected. We also agreed to extend the clearance between the edge of the pile cap and the anchor bolts for increased stiffness (see Photograph 7).
