This Building Information Modelling (BIM) Checklist is designed to serve as a reference for project stakeholders wishing to adopt BIM/VDC in a design-build project. Because integration and communication are critical to design-build project delivery, this checklist assists users in determining which BIM capabilities should be considered for all main project phases. The checklist discusses how each BIM feature may enable each of the top ten Design Build Benefits for any particular project.

Why Use a BIM Quality Assurance/Quality Control Checklist?
The BIM QA/QC checklist is nothing more than a tool that will assist you in creating an organized process, maintaining repetitive activities, fostering a good design habit supporting team members in memorizing work sequences in a Quality Assurance procedure, among other things, inside the project team.

We have given you a simplified BIM QA/QC checklist that you can use to streamline your BIM QA/QC process. Depending on your project, the checklist may differ somewhat from the example below.

List of BIM Quality Assurance and Validation Checklist
General Examine

Visual inspection of the model
Positioning of the origin point
Project, site, and building names
Building story naming
Mapping of IFC classes for all objects in the model
Tagging all objects and using the LOD parameter correctly
Room naming in the model
Check Your Space

Examining the available space inside the error range
Examining each floor space
The space program’s space number and name are being confirmed.
space numbers’ unique identifiers in BIM data being checked.
Design Review

Compare architectural and civil property lines.
Match architectural building measurements with structural Definitions of certain kinds and needed qualities such as item material.
MEP Check

The MEP plan corresponds to the architectural and structural plans.
Every piece of equipment is depicted on the plans.
The schedules display all of the equipment.
Coordination of MEP clashes
Construction Check

Conflict coordination between various architectural objects such as beams, columns, and beams.
Coordination issues between similar types of construction objects.
Model Improvement

Errors and clashes should be avoided.
Ensure that all requirements are followed. Ensure that there are enough geometric components, that they are in the proper place, and that they are functional.
Confirm that the client’s criteria have been satisfied.
Remove any unneeded perspectives and plans.
Remove any unneeded groupings.
Check work sets.
Audit file purged.
Benefits of BIM QA/QC Design Model Validation
Validation of Design Models: By guaranteeing that the 3D BIM model is flawless and can be used as a reference during construction, the QA/QC analysis is made simple.
Risk Mitigation: The future risk associated with a 3D BIM Model that has not been quality checked, such as unanticipated design conflicts, may be resolved in the model beforehand.
Cost Control: Accurate clash-free 3D BIM models reduce material waste and hence save money on materials.
Restores the Company’s Reputation: Errors in the BIM model might have a negative impact on the company’s reputation. It is critical to do QA/QC on the BIM model before making it available for building.
Conclusion
BIM (Building Information Modelling) is now an unavoidable need in the architectural, engineering, and construction (AEC) business. Using BIM Modelling, Revit BIM models from several disciplines may be integrated into a single data model. Architecture, structural engineering, and MEP engineering are examples of such fields. A clash-free and coordinated BIM model for the building construction process may be generated utilizing a checklist for BIM Quality Assurance and Quality Control. Because construction contractors need the exact data given by these models to build the structure, quality assurance is essential in the AEC industry. Project faults may have an influence on cost, timing, and even corporate reputation.

Gaza residents who have lost family fear more destruction as ground assault looms By Reuters

GAZA (Reuters) -As Israel prepared on Sunday for a ground assault on the Hamas-controlled Gaza Strip, Palestinians who have lost numerous family members in air strikes were bracing for more destruction if Israel hits back on an unprecedented scale on its territory.

Um Mohammad Al-Laham sat next to her 4-year-old granddaughter Fulla Al-Laham, who lay in a Gaza hospital which like others is operating on low supplies of medicine and fuel.

She said an Israeli airstrike hit the family home, killing 14 people including Fulla’s parents, siblings and members of her extended family.

“All of a sudden and without warning, they bombed the house on top of the residents inside. No-one survived except my grandchild Fulla. May God cure her and give her strength,” said the grandmother, who has witnessed many wars between Hamas and the Israeli army over the years. She says this is the toughest.

“Fourteen people martyred, no-one was left except Fulla Saeed Al-Laham. She doesn’t talk, nothing, just lays in her bed and they give medicine.”

One other 4-year-old child in the family had also been left with almost no relatives, the grandmother said.

Israel has unleashed the heaviest air strikes ever on Gaza in retaliation for the biggest attack on the country one week ago by the Palestinian militant group Hamas since the 1973 Arab-Israeli war.

Israel has vowed to annihilate the militant group Hamas in retaliation for a rampage by its fighters in Israeli towns eight days ago in which its militants shot men, women and children and seized hostages in the worst attack on civilians in the country’s history.

Some 1,300 people were killed in the unexpected onslaught, which shook the country, with graphic mobile phone video footage and reports from medical and emergency services of atrocities in the overrun towns and kibbutzes.

Israel has responded with the most intense bombardment Gaza has ever seen, putting the small enclave, home to 2.3 million Palestinians, under siege and destroying much of its infrastructure.

Israel has told Palestinian to leave their homes and move south.

Hamas urged people not to leave, saying roads out were unsafe. It said dozens of people had been killed in strikes on cars and trucks carrying refugees on Friday, while medics, Hamas media and relatives say whole families have been killed in the air strikes. Reuters could not independently verify these claims.

Some residents said they would not leave, remembering the “Nakba,” or “catastrophe,” of 1948 when many Palestinians were forced from their homes during the war that accompanied Israel’s creation.

Israel has intensified its bombings across Gaza City and the north. Gaza authorities said more than 2,300 people have been killed, a quarter of them children, and nearly 10,000 wounded.

Rescue workers searched desperately for survivors of night-time air raids. One million people have reportedly left their homes.

The expected Israeli ground offensive combined with the air strikes themselves have raised fears of unprecedented suffering in the narrow, impoverished enclave.

Witnesses in Gaza City told Reuters the Israeli offensive had forced more people from their homes. Gaza’s largest Shifa hospital was overcrowded with people who had fled their houses.

“We are living the worst nightmare of our lives. Even here in the hospital we are not safe. An air strike hit in the area outside the hospital around dawn,” said a 35-year-old woman who declined to give her name.

Taking the road to southern Gaza, which is considered safer, has become more difficult as several people who had made the journey say Israel continues to bomb around it.

Ashraf Al-Qidra, spokesman of the Gaza health ministry, said 70% of the people in Gaza City and the north of the strip are deprived of health services after the Palestinian refugee agency UNRWA evacuated its headquarters and suspended its services.

East of Khan Younis in southern Gaza, where hundreds of northern residents have fled to, some locals cooked for displaced people, using firewood to prepare 1,500 meals of meat and rice donated by residents.

“We used to cook on cooking gas for the first two days but we are running out of gas, so we are cooking on firewood,” said Youssef Abu Assi, one resident helping out.
