structure marking works

structure marking works. In this stage the project team uses precise survey instruments and approved drawings to establish the exact location of all structural elements on the site The scope includes setting out primary grid lines benchmarks and level references with high precision Surveyors and site engineers mark column positions wall alignments footing edges and opening locations Surface marking is carried out with spray paint wooden stakes and nylon tapes to guide excavation formwork and reinforcement placement All marks are checked against design tolerances to ensure accuracy and prevent delays and rework

concrete formworks

concrete formworks. The formwork phase involves designing assembling and installing temporary molds to shape fresh concrete until it cures and gains strength The contractor selects appropriate materials such as plywood steel panels and timber beams and ensures tight joints to prevent leaks Formworks are braced and supported with shoring props and walers to withstand concrete pressure Quality checks include alignment level and surface finish inspections before casting The formwork design also incorporates access points and lifting inserts to facilitate safe construction and demolding

infrastructures preperation works

infrastructures preperation works. During these works the contractor prepares the site for all below grade utilities and foundations The tasks include excavation leveling and compaction of soil installation of drainage pipes manholes and conduits as well as placement of gravel and sand bedding for uniform support Geotechnical tests verify soil bearing capacity and compaction levels Safety measures include shoring of trenches and monitoring of groundwater The prepared infrastructure base ensures proper load transfer waterproofing and longevity of the structural elements that follow

concrete reinforcement works

concrete reinforcement works. In this critical phase reinforcement bars and welded meshes are cut bent and positioned according to structural drawings The contractor uses high strength steel rebar tied together with wire to form cages for columns beams slabs and footings Spacers ensure precise concrete cover and protect the steel from corrosion Quality controls include bar size verification splice length measurements and tie spacing inspections Reinforcement works are coordinated with formwork to maintain clearances and structural integrity The reinforced cage assembly is approved before proceeding to concrete casting

concrete casting works

concrete casting works. This stage involves mixing transporting placing and curing concrete to form the structural elements The contractor selects the appropriate concrete grade and admixtures and organizes ready mix delivery or on-site batching Vibration and levelling tools ensure full compaction and uniform surface finish Temperature and humidity are monitored to optimize curing Curing methods include water spraying and covering with curing membranes to prevent moisture loss Concrete specimens are tested for strength development and the cast elements are inspected before allowing formwork removal

walls construction works

walls construction works. The walls phase covers building vertical elements using reinforced concrete masonry or precast panels The contractor sets up plumb lines and bracing to maintain straightness and alignment Reinforcement cages are placed within formwork prior to casting for concrete walls For masonry walls the team installs concrete blocks or bricks with mortar layers and reinforcement where required Openings for doors and windows are framed and lintels installed Wall surfaces are finished with screed or render as specified Inspections verify verticality joint thickness and structural continuity
