Project:   Site investigation for Ullapool Harbour development Client:     Ullapool Harbour Trust
	To provide for the future construction of extended storage, handling and parking facilities at the UK's second largest fish handling port and Western Isles ferry terminal, Caledonian Geotech were engaged to quantify tidal current sand access conditions for foundation engineering and investigate potential sources of backfill material.
	This investigation comprised hydrographic, marine geophysical survey, grab and dredge sampling, drilling from a platform and the inspection of existing structures. Studies across a preselected dredge area towards the open sea and at a quarry near the town concluded that the former offered suitably composed and graded sediment for backfill requirements. Indeed, only some 0.3m would need to be skimmed off the 11-12m thick deposits to afford the necessary volumes. Underwater photography identified damage to the existing piers and the necessity to clear fishing debris prior to construction. Caledonian Geotech completed the contract with the drawing up of design criteria for an anchored sheet pile retaining wall which was to comprise the first phase of construction.
