MHP, over the past fifteen years, has developed survey techniques that repeatedly achieve tolerances of 0.1mm. With the use of appropriate technology and equipment the following main tasks are covered:

• Plumbing of tall vessels and towers into vertical position (±5mm tolerances);
• Shimming of concrete bases for heat exchanges, compressors, drums, etc. (±0.5mm tolerances);
• As built determination of pipe networks and related service infrastructure;
• Precise positioning of mechanical equipment within defined tolerances.
• Precise alignment of rollers (±0.1mm tolerances);
• Precise positioning of machinery within defined tolerances.

MHP's most noteworthy participation in this aspect of survey is demonstrated by past and present involvement in:

• Hillside Aluminium Smelter - Richards' Bay, RSA
• Mozal Aluminium Smelter - Maputo, Moçambique
• Genref and Sapref Refineries - Durban, RSA
• Hulett Aluminium Expansion Project - Pietermaritzburg, RSA
