Questions related to Construction
A structure consisting of three portal frames has proposed to have two of the three portal frames dismantled and have a multi-story superstructure built in its place with a basement.
With no experience in the geotechnical field I am unaware of the approach to take of building the superstructure alongside the remaining portal frame without encroaching on existing foundation supporting the portal frame - destabilizing the soil.
My initial thoughts were to either underpin the existing foundation and pour a combined footing at the basement level to support the existing and future building, or alternatively building a meter away from the existing building and cantilever a section of the new building.
Any opinions and thought would be much appreciated,
Thank you in advance for your time.
There is nothing worse for curb appearance than chipped and cracked concrete, particularly in steps. But you don’t have to put up with that blight any longer. By the result of weather changes exerted on an existing construction for prolonged time, it causes contraction and expansion those gradually results concrete steps cracks and break up with time.
Dear researchers, I would like to get expert opinions on how to fix this issue with,
prolonged sustainability .
Your answers are highly welcomed.
Complex graphical sketches are highly involved in Culmann's methods. Therefore, it is highly prone for getting deviations in magnitudes for resultant pressure on retaining wall. I would like to get suggestions from RG colleagues on why Culmann's graphical approach is mostly preferred in many research papers albeit Rankine's method is easy and precise in terms of equations and substitutions. I would welcome answers from both theoretical and practical perspectives.
I would love to take on any literature recommendation on basics of housing, i.e. land, materials, roofing, foundations, isolations etc.
Anything to have a holistic view of the basics of housing construction, preferably in English or Polish.
Happy to return the favour in recommending similar 101 in economy or finance.
We are conducting a research on Role of human factors in achieving sustainability in construction.

Your participation will be important to us.
We thank you very much for your participation.
By checking the monthly project progress report of any construction project, we can track the actual cumulative project progress in percentage. But it may differ from the planned cumulative progress percentage for that month due to the several delay causes on the project. So, can we calculate the schedule cumulative percentage of work completion for that month by comparing the baseline schedule and as built schedule of the project?

Green roofs are becoming increasingly popular among researchers, engineers and related construction stakeholders to mitigate food crisis, Urban heat island effect, rainfall scarcity and enhancement of thermal comfort in urban ecosystems. Substrate is the most important component of a green roof. Our research team has carried out an extended systematic review regarding all the types of green roof research in the past 50 years and published a research article in Frontiers in Built Environment:
In your perspective, apart from the fields mentioned in our research article (link given above),
What are the scopes available within green roof substrates-related research for future studies? Are there any justifications for the choice?
Trying to mitigate early-age fractures in concrete buildings is crucial for ensuring adequate durability, minimising potential strength loss, and lowering maintenance costs. Because these cracks challenge the residential comfort and the aesthetic appearances of buildings.
So, what are the alternative measures adapted to mitigate arly-age cracks in the construction industry?
Is there a data sheet somewhere listing building requirements for staircases across various European countries?
I am based in the Netherlands, and trying to design a staircase.
The 'bouwbesluit' (building regultaions) of the Netherlands is very different from its neighbouring countries of Germany and Belgium.
The building regulations cover things such as minimum width of staircase, maximum angle, maximum height of one step, and minumum horizontal distance of one step, etc.
I am curious how I can design a staircase that would be practical to build in multiple different countries.
Is there any collected data on this that includes multiple countries?
I would be very interested if other people have encountered a similar problem?
As it is evident, concrete production industry, especially cement has put the environment in a crucial situation via greenhouse gas production, as well as natural resources (e.g., sand) consumption. what could be done in order to make a shotcrete mix design more sustainable in order to achieve a good properties (e.g., mechanical, workability, etc.) product with less environmental footprints?
The above of our two research articles are two of our important efforts on how to conserve the soil and use it for the enhancement of reforestation to mitigate climate change impacts such as Urban Heat Island, loss of endemic species, scarcity of water and greenhouse gas emissions which are the leading concerns in urban built environment. Our articles have addressed a way to achieve the sustainable development goals such as SDG6, SDG12 and SDG 13.
Soil resources are most critical prerequisites those need to be conserved, utilized and given back to the earth to enhance the sustainable existence of living organisms. Current technological trends are mostly focusing on mining the soil resources and fulfilling the human needs using anthropogenic activities. This trend needs to revisit, addressed the research gaps and more interests need to be shown by researchers and stakeholders to enhance the optimum usage of soil resources with minimal harmful effects to nature.
I request the researchers to provide your opinions in this regard. Thank you.
Hi, I'm a final year building surveying student. I'm looking into the UK net zero carbon emissions target by 2050. More specially exploring non-domestic properties and carbon emissions. Anyone got any ideas in which I can aim my research at? Any help would be great :)
How can an energy independent home be built?
How can a zero-energy (energy-neutral) house be built?
How can a zero-emission and energy- and climate-neutral house be built?
What combination of energy efficient building technologies and renewable energy sources should be used to build a fully energy independent home?
What are the key priors for sustainable, environmentally friendly construction?
Various solutions are being used in the construction industry to reduce energy consumption and CO2 emissions into the atmosphere. New building materials are being used, as well as insulation materials for facades to reduce heat loss. Various renewable and emission-free energy sources are used (windmills, photovoltaic panels, others). Thermal (in winter) and/or cooling (during hot weather) energy-generating devices based on heat pumps, air conditioners, etc. are used.
What are currently known to be the most convenient, sustainable, energy-efficient and cost-effective combinations of applied energy-efficient building technologies and various, especially renewable/zero-emission energy sources in fully energy-independent houses?
What do you think about this topic?
What is your opinion on this subject?
I invite you all to discuss,
Thank you very much,
In recent years, there has been development of some innovative construction technologies that are changing the way we build. There are many new technologies that will have a significant impact on the future of the construction industry.
Today, construction companies are able to complete projects more quickly and efficiently than ever before. There are new technologies in demand for the future that will help with accuracy, sustainability and faster construction.
Based on your point of view, what are the types of construction that can be used in future?
To whom it may concern...
Case shown in pictures below need to stop in front of it...
Starting with the way of supporting slab before casting.. the question appear...
Based on your engineering opinion, and supporting method that you might used... is what shown in pictures attached ,.. enough.. ?
Then... whom responsibility is that... if slab fail during casting process, as there will be additional loading of pumped concrete and labors also ...? where that will be the most important question....
To whom it may concern...
Case shown in pictures below need to stop in front of it...
What the mean of overload... What will be the meaning of calculated loading before design... and.... What really mean the structural design based on submitted data..
All, in general,.. knows that.. design start with converting functional use of the building to loading on structural element... then start design element by element ...
So, what might be the supposed loading to one story house... based on all adopted code... ? this is the first question..
Then what you think, .. or what the supervisor engineer might think the value of such loading on that slab shown in pictures attached... ? this is the second question...
Then at last... whom responsibility is that... if failure occur...? where that will be the most important question....
Limited education with low experiences causes such cases, ... or... we need to ask the supervised engineer if he care...
Do construction professionals (especially construction managers, project managers and quantity surveyors) need environmental sustainability competencies?
Looking at how the construction activities affect the environment and yes we have environmental engineers but wouldn't it be good to have construction professionals that are also aware of the environmental impacts/issues, especially during the construction, operation and demolition phases.
Assistance will be appreciated.
I hope this message finds you in good health.
I am a MSc student at Anglia Ruskin University. I am studying Construction and Civil Engineering Management.
I am currently working on my dissertation and would like your valuable help.
I am investigating the positive impact offsite modular construction may have on the housing crisis prevalent in the United Kingdom.
For my study, I have decided to conduct a questionnaire so that I can get a deeper look into the views of senior managers and or people working in the construction of the houses in the UK. I aim to explore the adequacy and effectiveness of offsite modular construction. The possibility is that a change in construction systems could speed home completions and may mitigate the housing shortage.
I believe that with your help I can get a better understanding of this study and an idea of how to clarify the housing shortage. I am asking for 5 minutes of your time. In order to take part in a five-minute questionnaire that will possibly provide insight into the housing shortage issue.
Please feel free to contact me if you would like to take part in this study.
Thank you for your time.
An intelligent planning of rooms based on Passive Solar design could effectively mitigate energy consumption and also promort the comfort. Anyways, what are the different methods used in the construction industry to implement passive solar design in rooms? Any scientific theories? Any case studies?
I would like to receive feedbacks from fellow researchers.
Cement has been in human use throughout history, and due to its binding nature, it is regarded as the backbone of the construction industry. A recent edition of the journal Nano Energy published the results from major breakthrough research conducted by engineers from Incheon National University, Kyung Hee University, and Korea University. The researchers have invented a cement-based composite (CBC) that can be used in concrete to develop electrical properties without affecting its structural performance. But what if cement could be used to generate electricity?
Any ideas from researchers?
Thermal mass is a property of construction materials to absorb, store, and release heat energy. It is an important element of passive solar house design and can be utilized for passive solar heating, passive solar cooling, or both. I would like to know, what is the most effective technique to quantify these kinds of thermal masses in an existing construction?
Picture attached shows the case of complete reinforcement of raft foundation, but after sand storm, as appear, more than 20mm layer form from sand under the reinforcement.... on your opinion, what might do to continue with work...?

I'm currently carrying out an investigation of Occupational Health and Safety (OHS) pricing in competitive construction tenders in my home country Zambia. I would like to basically find out what you take into consideration in relation to health and safety when pricing for a construction job? Do you look at safety as more of an investment or just an item you need to keep in mind when coming up with a round figure for your PnG's?
Humble regards and encouragement.
we are all aware of inefficiencies and waste (time, material, talent) in the Architecture, Engineering and Construction (AEC) sector. We also do know that we need to increase overall productivity and quality while reducing costs. But is it possible in the "status quo", using existing processes, materials and tools?
New technologies have demonstrated technical feasibility in R&D (both in Academia and Industry). Yet, there seems little demand from the market itself. How is that - are we lacking appropriate business model design, technology transfer capabilities or modes of open innovation?
Do we need entrepreneurship for these new technologies in construction?
Happy to hear your opinion!
What can you say about building disassembly? For you, in you own opinion, is this method of construction in the present time effective and will it be develop through time?
Please compare various common programs, e.g., ETABS, TEKLA, etc. as well as the new generation of parametric ones, e.g., Karamba, Kangaroo, etc.
Please reply by referring to valid scientific papers.
Some supervisors are exceptionally adorable. However, a few colleagues have shared some bitter experiences they encountered with their supervisors.
Experience has it that the relationship between the Student (researcher) and a supervisor (mentor) depends on the zeal and input of the student. The ability to exhibit originality would embrace a smooth process.
To what extent do you Agree / Disagree with my stand? (See below).
1. Have a meeting with your supervisor at the start of the study to understand the "do's" and "don'ts"!
2. Take note of the Memorandum of Understanding for the study.
3. Always be time-bound in your submissions.
4. Follow instructions and respond to queries accurately and promptly.
5. Avoid plagiarism and observe ethical procedures!
Per your experience do you think these points when followed, would make the process smooth for students’ success?
Kindly share your view, Add, agree, disagree, and critique.
I would like to hear your opinions regarding sharpening the orientation of my career by focusing on what matters most just looking at the trends and how the world is changing.

Building Information Modeling (BIM) is an intelligent 3D model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructure.
Due to the fact that the land property market is limited, people implement investment projects not only directly on their surface, but also:
- below them (e.g. tunnels, but also a hotel 100 meters underground) and
- above them (for example, hanging bridges, as well as offices in "houses" on trees),
- as well as "in the ground" (including a cave apartment, a hotel in volcanic rocks, an underwater hotel).
Anyway, these are often large and very recognizable investments. Their wide scope induces to ask many questions, e.g.:
- what investment projects have already been implemented or are planned in individual cities in the world?
- In what direction can they develop?
- What ideas that seem impossible today may become possible in the future?
- How is technology developing, e.g. in the field of construction?
- Are such projects likely to be affordable for a wider group of consumers?
- How do these types of investments affect the market value of companies implementing such projects or having them in their investment portfolios?
- do such investments include the same specifications as classic real estate investments (connected with liquidity, discount rate, rate of return etc.)?
- Others questions?
It is always useful to learn from others experiences they encountered in solving challenging Real world problems, and to learn from their past successes and failures. Experience is the best teacher in life.

i have a project, the pile design assumption is using casing pile for reinforcement of pile, could it be? (we used cast in place method)
Building construction in developing countries, especially in small towns and rural areas, have been dominated by an egalitarian architectural practices or the carpenters, masons, mistries, etc. Here, even the architects finds themselves to be the outsider as far as construction is concern. Now, let’s move to a slightly different scenario where the licensed architects holds the key to a project and everyone else, except the client, is a consultant or contractor and vendors, etc. In this second scenario, do the architects require specialized assistance of building scientists, researchers, professors, etc? If yes, how can they contribute to the sustainability factor? If no, why so?
Another way of putting these question would be: “Do we need specialised studies in Masters and PhD to effectively design a building?”
I am working on case study(approx. 20 to 25 projects) research related to failure of construction projects. Since in construction projects contractor, client and consultant are main stakeholder so in order to identify the failure causes and to validate the data do I need to interview all of them?
