There must be an investigation of the natural drainage at the excavation site for a condominium tower expected to become Cebu City’s tallest building at 55 storeys, an expert said.

Engr. Fe Walag, University of San Carlos-Water Resource Center (USC-WRC) director, said the investigation must be on the natural drainage within the vicinity of the P1.7-billion Horizon 101 Tower condominium along Gen. Maxilom Ave., Cebu City.

Walag said the USC-WRC was commissioned by the condominium developer Taft Property Ventures Development Corp. (TPVDC) to conduct a hydrology study at the site.

She said the study was submitted last year.

A portion of the retaining wall collapsed at the excavation site of the 55-storey Horizon Tower 1 last Tuesday afternoon, affecting 10 families.

Walag said the presence of water in the area and structural integrity of the construction should be checked.

The hydrology study was quoted by senior geologist Elena Lupo in the geological site scoping report of the Mines and Geosciences Bureau (MGB 7) dated June 9, 2011.

Lupo said previous works by MGB 7 on mapping and assessment of floodprone areas in Cebu City identified the area in Barangay Cogon-Ramos as highly susceptible to flooding and that a history of flooding during heavy rains and typhoon has been recorded.

Lupo said the USC-WRC study resulted in the design of the present drainage system where the surface run-off water is drained in a large catchment area northwest of the project site.

The proposed drainage line and final outfall with run southeast toward Lahug River.

TPVDC project director Engr. June Umali said the moist soil at the site is due to rainwater and the presence of houses.
