BIM 4D Scheduling

Now that we had explored 3D in Revit, we are currently exploring on how to utilise 4D scheduling in our projects. Below is my notepad, recording the outcome and studies of BIM 4d Scheduling/Phasing. 

What is 4D Phasing ? 

4D adds the time factor of construction. It combines 3D model with time which allow architects/engineers, contractors, stakeholders to communicate the project phasing. It supports the understanding of project phasing, hence detecting any possible construction impact/complications, reduce waste, and even flow.

How Does 4D Works ? 

It works by linking each activity of a gantt chart (microsoft project file) to BIM, giving rise to an animated models representing the planned construction sequence set against time. It is useful in helping construction team to visualise logistical issues or inefficiencies, exposing detail such as out of sequence work or scheduling, or scheduling conflicts between multiple trades, analyze "what if" scenarios and macro level construction phasing strategies, in order to achieve optimization of construction schedule.

A great and helpful video in creating a 4D simulation is embedded below.

Urban Solar : Beyond Numbers

23 June 2015, Urban Solar: Beyond Numbers @ NUS.

A few of us registered for this discussion/talk regarding Urban Solar : Beyond Numbers organized by Singapore Safety Glass, AGC and SERIS. 

While it can be a little too technical for us, it was nevertheless and interesting session. 
Some of the interesting takeaways captured in the photos below : 

The Building and Construction Authority partnered with US-based Lawrence Berkeley National Laboratory (Berkeley Lab) on 2012 to build a facility for test-bedding green building technologies. The collaboration is a great move in developing new innovations and solutions for greater energy efficiency of buildings in Singapore, thereby reducing carbon emissions and contributing to sustainability of the built environment. 

The Rotatable Laboratory will be constructed on the roof of the new extension in 2015 – the first to be built in Asia. The Laboratory will allow professionals and researchers to test building materials, components and systems that they have developed and monitor their effectiveness under Singapore local climatic conditions. 

Potential areas of study which can be carried out in rotatable laboratory include air-conditioning, building envelope and facades, lighting and control system, data acquisition and sensing system and other technologies. This allow researchers / builders eg architect to test bed design in working towards green design & sustainability. 

Talking about BIPV implementation in line with Green Building Design and Sustainability, an interesting topic was brought up for discussion by Prof Runa Hellwig (SERIS) on the perceived barriers on the implementation of BIPV. See photo below.

Prof Runa also shared an interesting collaboration project with WOHA in a Solar Architectural Interface Project, designing BIPV Design-Prototypes.

Further to the event, we had Mr. Yukihiro Harima sharing some of AGC's new solar cell such as green colored cell, sphelar and sudare which are pretty interesting. Green coloured solar cell are cells with green quartz liked embedded in solar glass. Sphelar, which is currently still under development has small silicone balls connected to each other and is embedded in solar glass, while sudare (vision glass that can be see-through with Solar cells by Sanjoule) takes the idea of vintage Japanese bamboo blinds and incorporated as sun-shading as well as photovoltaic cells.

It was a fruitful evening learning new things. 

BIM Execution Plan for PMs

23 June 2015, Meeting on BIM Execution Plan for Project Managers.

As the office is progressing towards BIM Execution in our projects, we love how little steps we are taking now are affecting the future. Today our BIMguru gave a briefing on what's in a BIM Execution Plan, the process, parties involved, who should be leading the creation efforts and the way forward. Though it was a short session, but it was essential to share the possibilities of BIM with project managers who were involved in project delivery. 

Here's the copy of slides for reference. 

The black patch in the 3rd last page in the document is the video, which i embedded below.

The meeting ended with an interesting video by B1M Co-founder, Fred Mills presenting the possibilities of BIM. It is so huge and amazing. Watch the video and get excited. #BIMspiration #BIMoment

We would like to thank our BIMguru Laurenzo Federico for the short and informative briefing session.
