Building is one of the biggest financial decisions you will make, and the difference between a smooth project and one full of surprises often starts with understanding the phases. This guide explains them as we actually deliver them, and what deserves your attention at each step.
Before you start: drawings and permits
Works should not begin without approved architectural, structural, electrical and plumbing drawings and a valid building permit. Contractors price from the drawings, so clearer drawings mean a more accurate quote and fewer variations later.
Phase 1: excavation, backfilling and site preparation
The site is cleared and set out, then excavated to the level specified in the drawings and soil report. After the footings are cast, backfilling is done in compacted layers. Poor compaction here is a common cause of floor settlement later.
Phase 2: footings and columns
Blinding concrete, then footing reinforcement and casting, followed by column necks and ground beams. Check that reinforcement matches the structural drawings before casting, and that the concrete is cured with water afterwards.
Phase 3: slabs and the concrete frame
Formwork, slab and beam reinforcement, casting and curing, repeated for every floor. This is the longest part of the structure and needs the closest engineering supervision, because mistakes are hard to correct later.
Phase 4: blockwork, plastering and services
Blockwork for external and internal walls, then electrical and plumbing runs, then plastering. Getting the order right avoids breaking finished walls.
Phase 5: tanks and drainage
The water tank and septic tank (or connection to the public sewer) are a core part of the project. We have built many concrete collection and septic tanks on government projects; waterproofing, correct reinforcement and drainage falls make the difference.
