sewer maintenance work, will include sections covering daywork rates for labour, general items, earthworks, in situ concrete, concrete ancillaries, pipework, brickwork, blockwork and masonry; painting; sewer renovation and ancillary works. Contracts are usually awarded to the contractor who offers the lowest rates. A tender total can be calculated in the normal manner if weighting factors are included in place of quantities, indicating the likely ratio of the work to be undertaken associated with individual items. |

Good management decisions cannot be made without a sound technical understanding of the sewer network and how it performs under different conditions. Training programmes should include training in such areas as pumping station behaviour, and repair and rehabilitation techniques for sewers. Manual staff are able to carry out their duties more effectively if they are given basic instruction in the operation of the sewerage system and its ancillaries, and this is especially true where the sewerage system has recently been introduced, such as in Asafo. |
