The joint if any, shall be carefully handled as the poor joining in the concrete process would result in weak spots which would become the locations of future problems in the channel. In order to ensure the flow of water with very low energy loss it is necessary to maintain the channel geometry in the construction. The machinery choice is also a very important component in the construction process. With a proper attachment for levelling and material lining activities the channel construction could be undertaken on a continuous mode (US patent,, 1984). This would help to maintain the required slope and the roughness condition the important criteria that influences the velocity of flow. The concrete mix design shall be prepared as per the design specification and if the construction need to be carried out in adverse condition addition of admixtures is necessary to facilitate the retention of properties of prepared concrete . Finally, proper curing of the concrete works is also required to have the better durability of the construction process.
The foot bridge construction requires more care as it is indented to carry moving loads with supports given only at the locations as specified in the design document. The major components of the foot bridge , constructed over the diversion channel , are support piers at the ends and the bridge slab.
