Section 4.3.4
Excavations
Excavations for strip and trench foundations need to take account the design dimensions, local effects and ground conditions.
Ground levelled and prepared.
Foundation accurately marked out.
Foundations neatly cut and consistent line.
Trench sides are vertical and foundation bottoms level and clear of loose debris.
Foundation complete and ready for concrete pour.
Check foundation for correct depth, bearing strata and any localised conditions that may require reinforcement.
