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?
Relevant answer
Answer
Dear Shuraik Kader,
In view of the increasing risk of an energy and climate crisis, eco-innovation-based, green building technologies will be developed in the future to build homes that are significantly more energy-efficient and resistant to the negative effects of climate change. Consequently, the future will mainly develop pro-environmental, energy-efficient sustainable construction. Perhaps it will also be environmentally neutral construction based solely on natural building materials.
Best regards,

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?

Relevant answer
Answer
It depends on the climatic region where you live. Sufficient solar radiation or sufficient wind speed is necessary. If you have one of these two renewable resources then it is absolutely possible to build an energy independent house. The area of an ordinary house usually offers enough space on the roof to place enough solar panels for the general consumption of a house. You should select building forms and materials that allow an efficient use of energy and avoid energy losses.

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...
Relevant answer
Answer
Invariably the loading on one storey building roof with access is only `1.5 to 2 kN/m2 . and this is uni-formally distributed load. But if you pile up load in a small area more than the failure load of slab with concentrated load then the failure is imminent. this failure load can be calculated using yield line theory or by Hillerborg Strip method.
If you have this kind of loading then keep your props intact before you finish roof top work

Hi All,
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.

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?
Relevant answer
Answer
The simple muiltiplication of the mass by the thermal capacity as Bachir Achour proposes, is valid only at thermal equilibrium. Since buildings are always in a thermally dynamic state, this method strongly overestimente the active thermla capacity. When the ambient temperature continuously changes, the calculation is more complex, and needs solving the equation of heat. Simple mathematical solutions to determine the thermal mass of a multilayer plane building component under dynamic conditions are indeed described in EN-ISO 13786 as mentioned by Edwin Rodriguez-Ubinas.
An experimental method to determine the dynamic thermal capacity of a room was proposed by Van der Maas (see attched paper). The apparent room effusivity can be measured by recording the increase of the indoor temperature after switching on a constant power heat source.

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.

Dear peers,
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!
Relevant answer
Answer
Yes, we need entrepreneurship for new technologies in construction. Construction is one of the booming sectors in the economy. Activation of entrepreneurship in the construction sector is an important element of social and economic policy. Yes, we need entrepreneurship for new technologies in construction, especially in the field of green construction technologies, creating new pro-environmental construction technologies, new types of energy-saving building materials in order to develop sustainable construction.

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?
Relevant answer
Answer
Many real cases and studies show the real advantage of disassembly construction methods, especially in steel and timber elements, as they have the typical characteristics of a circular process (cradle to cradle). There are several aspects to be evaluated including cost, time, labour, and the actual benefits in terms of reducing environmental impacts, but I believe that with a proper disassembly plan already planned in the design phase, the whole process would be very simple, practical and cost-effective.

I propose the implementation of research development in the field of Global Logistics with the use of new information technologies, ICT, Internet and Industry 4.0, including IoT technologies, cloud computing, Big Data Analytics, etc. The use of these technologies allows for shortening logistic chains and the development of e-logistics. These processes may be helpful in transforming logistics in the context of the current SARS-CoV-2 (Covid-19) coronavirus pandemic. In addition, the research carried out can include the analysis of determinants of the transformation of traditional logistics towards sustainable green logistics.

I need to model a construction and demolition waste management network in order to maximize waste recycling. I read some works that use MILP. Among the software used are GAMS, JULIA, MATLAB and R. Are there other software that can be used?
Relevant answer
Answer
I have used most of the tools mentioned before. While each of them has its strengths and weaknesses, nowadays I have been constantly relying on the same tool for solving all kinds of optimization problems.
This tool is a combination of Julia programming language with the Julia package JuMP which defines (in my opinion) the most elegant and intuitive modeling language that makes it easy to try different solvers on the same problem by simply changing the solver name in the code. It also allows easy access to more advanced features of MILP solvers such as generic support for callback functions that can be used to modify the problem while solving it with the addition of valid inequalities and user-defined heuristics.
As an example, solving the TSP using the DFJ (Danzig-Fulkerson-Johnson) formulation that has an exponential number of subtour elimination constraints is straightforward with JuMP. You can simply set up a "lazy constraint callback" function that will check if subtours are present in the solution and if not, add constraints to break these subtours. This is particularly easy when considering only integer solutions, but you can also use the "user callback" function to cut off fractional subtours. JuMP has turorials of several important modeling paradigms that can be used as a basis for your model. Here are the relevant links:

Developing a Rating System for Building Energy Efficiency Based on In Situ Measurement in China
By: Zhao, L (Zhao, Li) ; Zhou, ZN (Zhou, Zhengnan)
DOI: 10.3390/su9020208
Abstract
Building energy consumption in China recently surpassed the US building consumption, and it is expected to increase significantly in the next decade pushed by the continuous population and urbanization increase. In response to that situation, the Chinese government introduced a series of building energy codes and rating systems to assess and enhance the building energy performance. The purpose of this study is to develop a rating system for the building energy efficiency, based on in situ measurement. The system is intended for office buildings in China's cold zone. An evaluation framework, graphic dominant point, and principle of data collection and processing are illustrated in this paper. Three existing buildings were rated under the new rating system. The authors believe that the new system will contribute to a more accurate and comprehensive understanding for asset holders and occupants, that report on the extent to which energy efficiency buildings have been reached. Rating results are expected to be a reference for the retrofitting of existing buildings and the design of new buildings. In addition, the outlook for the rating system was also discussed.

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?

Answer
Jaheer Mukthar Kp I am afraid that as it happens in life, in this case we are dealing with positive and negative consequences, e.g. in a natural context. Therefore, it is important to supervise this type of investment so that their location would cover rather areas where the positive effects will be maximized and the negative minimal (in each case it is to some extent an interference in nature). I wonder if they are already emerging somewhere in the world or will they arise in such unusual locations, e.g. special zones for business?

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 :)
Relevant answer
Answer
This is a world wide issue not just UK.
Why don't you perform a case study on the practicality of large energy storage solutions?
Main contribution to non-domestic carbon emissions is the power need of the growing population.
Based on the so called "duck curve" (you can google it) emissions of fossil power plants can be lowered or replaced with renewable energy if large scale energy storage can be implemented.
As building surveying you can perhaps look at the economic, area demand or other practical factors of big industrial scale energy storage.
For example: The largest portion energy storage of the world is pumping water when there is excess and running it back down when there is a demand. It takes massive amounts of space and needs elevation. While, this method being cheap making back it's investment in just over 3 years but expensive as it does not scale down well and requires massive initial capital costs. Thus alone it cant be the solution while it helps.
Feel free to message me if you would like to discuss this in detail...

As a method of the research we used Automated system-cognitive analysis (ASC-analysis), which is a new innovative method of artificial intelligence: it also has its own software tool – an intelligent system called "Eidos" (open source software) [1, 2, 3].
The Eidos-X++ system differs from other artificial intelligence systems in the following parameters:
- was developed in a universal setting, independent of the subject area. Therefore, it is universal and can be applied in many subject areas (http://lc.kubagro.ru/aidos/index.htm);
- is in full open free access (http://lc.kubagro.ru/aidos/_Aidos-X.htm), and with the relevant source texts (http://lc.kubagro.ru/__AIDOS-X.txt);
- is one of the first domestic systems of artificial intelligence of the personal level, i.e. it does not take special training in the field of technologies of artificial intelligence from the user (there is an act of introduction of system "Eidos" of 1987) (http://lc.kubagro.ru/aidos/aidos02/PR-4.htm);
- provides stable identification in a comparable form of strengh and direction of cause-effect relationships in incomplete noisy interdependent (nonlinear) data of very large dimension of numerical and non-numerical nature, measured in different types of scales (nominal, ordinal and numerical) and in different units of measurement (i.e. does not impose strict requirements to the data that can not be performed, and processes the data that is);
- contains a large number of local (supplied with the installation) and cloud educational and scientific applications (currently 31 and 199, respectively) (http://lc.kubagro.ru/aidos/Presentation_Aidos-online.pdf);
- provides multilingual interface support in 44 languages. Language databases are included in the installation and can be replenished automatically;
- supports on-line environment of knowledge accumulation and is widely used all over the world (http://aidos.byethost5.com/map5.php);
- the most time-consuming computationally, the operations of the synthesis models and implements recognition by using graphic processing unit (GPU) that some tasks can only support up to the solution of these tasks is several thousand times that really provides intelligent processing of big data, big information and big knowledge;
- provides transformation of the initial empirical data into information, and its knowledge and solution using this knowledge of classification problems, decision support and research of the subject area by studying its system-cognitive model, generating a very large number of tabular and graphical output forms (development of cognitive graphics), many of which have no analogues in other systems (examples of forms can be found in: http://lc.kubagro.ru/aidos/aidos18_LLS/aidos18_LLS.pdf);
- well imitates the human style of thinking: gives the results of the analysis, understandable to experts on the basis of their experience, intuition and professional competence.

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?”
Relevant answer
Answer
Depends on the nature of the project, and the project budgets. But, most projects would be short of funds. There are hardly any projects with surplus funds. So, hard to say.

Relevant answer
Answer
It sounds like you could consider your project to be a set of comparative case studies. If so, then I would recommend Yin's book, Case Study Research. His approach is to develop a "protocol" that you apply to each case, so that you have comparable data from all of them. This would not necessarily require you to interview a full set of stakeholders from each site, as long as you felt like you had high quality information for each of the crucial topics at each site.

If it can not be repaired, the contractor should remove construction with paying all the costs and even those resulting from the delay of work.

Upon your site experience, What are the main criteria need to be considered when design building against seismic?
Relevant answer
Answer
As written in:
SEISMIC DESIGN PRINCIPLES 
by Gabor Lorant
" The essence of successful seismic design is three-fold. First, the design team must take a multi-hazard approach towards design that accounts for the potential impacts of seismic forces as well as all the major hazards to which an area is vulnerable. Second, performance-based requirements, which may exceed the minimum life safety requirements of current seismic codes, must be established to respond appropriately to the threats and risks posed by natural hazards on the building's mission and occupants. Third, and as important as the others, because earthquake forces are dynamic and each building responds according to its own design complexity, it is essential that the design team work collaboratively and have a common understanding of the terms and methods used in the seismic design process. "
Also
"
SEISMIC DESIGN FACTORS
The following factors affect and are affected by the design of the building. It is important that the design team understands these factors and deal with them prudently in the design phase.
Torsion: Objects and buildings have a center of mass, a point by which the object (building) can be balanced without rotation occurring. If the mass is uniformly distributed then the geometric center of the floor and the center of mass may coincide. Uneven mass distribution will position the center of mass outside of the geometric center causing "torsion" generating stress concentrations. A certain amount of torsion is unavoidable in every building design. Symmetrical arrangement of masses, however, will result in balanced stiffness against either direction and keep torsion within a manageable range.
Damping: Buildings in general are poor resonators to dynamic shock and dissipate vibration by absorbing it. Damping is a rate at which natural vibration is absorbed.
Ductility: Ductility is the characteristic of a material (such as steel) to bend, flex, or move, but fails only after considerable deformation has occurred. Non-ductile materials (such as poorly reinforced concrete) fail abruptly by crumbling. Good ductility can be achieved with carefully detailed joints.
Strength and Stiffness: Strength is a property of a material to resist and bear applied forces within a safe limit. Stiffness of a material is a degree of resistance to deflection or drift (drift being a horizontal story-to-story relative displacement).
Building Configuration: This term defines a building's size and shape, and structural and nonstructural elements. Building configuration determines the way seismic forces are distributed within the structure, their relative magnitude, and problematic design concerns.
  • Regular Configuration buildings have Shear Walls or Moment-Resistant Frames or Braced Frames and generally have:
    • Low Height to Base Ratios
    • Equal Floor Heights
    • Symmetrical Plans
    • Uniform Sections and Elevations
    • Maximum Torsional Resistance
    • Short Spans and Redundancy
    • Direct Load Paths
  • Irregular Configuration buildings are those that differ from the "Regular" definition and have problematic stress concentrations and torsion."

Upon your site experience, What is the maximum storage time for cement in site?
Relevant answer
Answer
This really depends upon the type of cement and the conditions under which it is stored. At 20oC there should not be a problem so long as the relative humidity is maintained below 60%. Above this then there will be prehydration of the cement. This will lengthen the setting time and reduce strength development. If the relative humidity approaches 80% then the silicates in the cement will start to prehydrate and the loss in strength could well be ~30%.
At higher temperatures then it is likely that the effects will be more pronounced.
