9 Workmen and Equipment All workmen and equipment shall be clearly identified and they shall not be brought on site or removed without the written approval, of the owner, which shall not be unreasonably withheld. This is to avoid any unnecessary disruption of work. It is vital that the gang doing the installation are experienced in installing the type of court selected. Of course where additional courts are being added or old courts renewed then provision will have to be made for access of materials and equipment to carry out the work. This may involve the carriage of several tonnes across courts and this has the potential to do considerable damage if routing and timing is not properly planned. All work with respect to Safety, Health and Welfare must be carried out in accordance with Irish Labour Laws and Recommendations
