General
Construction Checklist are a set of pre prepared instructions or exercises that a Project Manager and his team must ensure their follow up and investigate to guarantee that the deliberate of a venture are of progressive and acceptable nature. The checklists are the tools that can help the project outcomes of being of qualitative nature, enhancing the project sustainability
The Common Types of Construction Checklists are:
Pre-Construction Checklists
During Construction Checklists
Post construction Checklists
Health, Safety, Security and Environment Checklists
Resource Availability Checklists
Quality Assurance Checklists
Features of Construction Checklists
Construction checklists are effective tools for risk mitigation and helps in maintaining measures related to health and safety.
Checklist development separates the complicated exercises / activities into simple, actionable steps and categorizes the items, materials and so forth in distinct way.
Checklists provide an exhaustive and satisfactorily organized development agenda for the effective execution of various development phases and activities. It helps to overcome the human mistakes.
The development of checklists helps in maintaining responsibilities and accountability.
Development of checklists act as relief measure to the management as it assures quality output.
Construction projects are outcome of application of art and science involving not only the various discipline of engineering, but also the knowledge of management for sustainability of the projects. The blog covers important aspects of civil engineering used in the project completion associated with practical knowledge of other branch of engineering for required workplace operations considering the importance of quality in all operations including the Health, Safety, Security, and Environment. The overall construction supervision must take care of all the aspects in workplace operations.
Concrete is a product obtained from mixing coarse aggregates, fine aggregates, cementitious and supplementary cementitious materials, fibers, water, and admixtures. The types of concrete mentioned here are from 7.5 MPa (ordinary concrete) to around 400 MPa (UHPC).
Very specialized plants with management controls are required for handling all such type of concrete and specially UHPC. Most the plants may not be able to fulfil the requirements. However, UHPC is available as ready to mix packs and can be purchased, transported, and used.
All the types of concrete (mass concrete and reinforcement concrete) require special attention right from material management, manufacture, transportation, and placement of concrete and there after curing of concrete. All these operations are handled by total quality people as per the requirement of work.
The magnitude of work may vary from project to project, and therefore it is important to have checks at various stages so that a quality product is delivered.
Here in this blog brief description of various stages in construction is described.

Project Concrete Requirements Management
All the types of concrete (mass concrete and reinforcement concrete) require special attention right from material management, manufacture, transportation, and placement of concrete and there after curing of concrete. All these operations are handled by total quality people as per the requirement of work.
The magnitude of work may vary from project to project, and therefore it is important to have checks at various stages so that a quality product is delivered.

A checklist as specified in reference to work requirements, must be prepared and used by construction team as baseline requirement. The baseline requirement may be different for different projects.
High Level Checklists for RCC
Following high-level checklists, are suggestive for reinforced concrete works, but not limited to:
- Checklist for general supervision
General Supervision Checklist Adopted by —————————-for site—————————Check For
| 1 | All the plans associated with scope, cost, time, quality, human resources, communication, risk, procurement, and stakeholder management are in place. |

| 23 | Required existing screen sizes are in order at Processing Plant |
| 24 | Batching plant (BP) calibration arrangement exists as per requirement and insure full calibration of BP at a time. (Aggregate, cement, admixtures, & water) |
| 25 | Automatic report generation process at BP is functioning properly. It is must to check the outputs and inputs for effectiveness. |
| 26 | Bins at BP are well guarded to avoid intermixing different type o materials. |
| 27 | Workability requirement of concrete (slump) is site specific need. Accordingly, it should be mentioned in OK card by the CA and work shall not be started without OK cards |
| 28 | Steel and cement should be from approved manufacturers. Cement shall be used based on first in first out within three months of manufacturing dated |

Tips for Making Construction Checklists
Construction Checklists are part of project construction management system. They provide broad information to carry forward the project through its various stage to a successful closure stage
The construction checklist developer must have a good understanding of the project.
The checklist should be functionally good and easy to understand and follow.
These checklists must be discussed in toolbox meetings so that construction workforce is aware of them.
