Project Title: Proposed Iconic Structure For Invent Media Limited At Western Avenue, Surulere, Lagos

Location Visited: Western Avenue, Surulere, Lagos

Date/Time of Visit: 11th 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).
