Finishing Concrete

Finishing Concrete

Concrete finishing starts immediately after the concrete has been placed and consolidated. The initial step, screeding, involves leveling the concrete surface by removing excess material to flush it with the formwork's top. Following this, bull float or darby are employed to smooth the surface further, effectively lower high spots, fill low areas, and ensure larger aggregate particles are embedded within the concrete. This preparation is critical before the appearance of bleed water, as its...

Manufacture of Concrete Masonry Units

Manufacture of Concrete Masonry Units

The process of manufacturing concrete masonry units begins by mixing stiff concrete composed of Portland cement, aggregates, and water. This mixture is then poured into metal molds. To ensure the concrete settles uniformly and to avoid separation of its components, the mixture in the molds is subjected to vibration. Shortly after, the still-wet blocks are removed from the molds and placed on racks.
These wet blocks are then transported for curing, which can occur in one of two environments: a...

Area of Science:

Construction Management
Industrial Engineering
Operations Research

Background:

Developing nations like Vietnam face construction sector challenges, including limited historical risk data and adoption of modern risk mitigation strategies.
Enhancing construction management practices is crucial for project success, particularly in specialized finishing works.

Purpose of the Study:

To implement Lean Construction (LC) principles enhanced by discrete-event simulation (DES) for optimizing marble floor finishing processes in Vietnam.
To identify and reduce waste within the construction process through simulation and lean methodologies.

Main Methods:

Application of Lean Construction (LC) principles combined with discrete-event simulation (DES) using EZStrobe software.
On-site data collection and simulation of the marble floor finishing process to analyze activity durations and identify bottlenecks.
Implementation of lean techniques such as Just-In-Time (JIT), reduced batch sizes, resource prioritization, and multi-skilled teams.

Main Results:

Achieved a 13% reduction in construction cycle time.
Demonstrated a 141% improvement in process efficiency.
Reported a 268% enhancement in average productivity and a 96% reduction in labor costs.

Conclusions:

The integrated approach of Lean Construction and discrete-event simulation significantly optimizes marble floor finishing operations.
The study provides a valuable reference for improving construction performance in finishing works for managers and engineers in Vietnam.
Lean Construction principles, when applied with simulation, offer substantial gains in efficiency, productivity, and cost reduction.
