The following benefits to the client have been identified within this programme. The company’s early engagement with HE and Costain and its understanding and relationships with the affected statutory bodies and various apparatus owners ensured that all parties worked collaboratively to identify best design practice to ensure program surety and cost savings. Seasonal outages were avoided at an early stage by ensuring that orders were placed early.
The company has successfully negotiated protection measures wherever possible and kept the utility diversions to program and budget with strong management avoiding program slippage to the start of the main construction works.
“The skilful management by Gattica significantly contributed to Highways England’s banking a £2m efficiency saving on the scheme directly attributable to the management of Statutory Undertakers during the construction phase (equivalent to 2.5% of Scheme Budget).”
