This chapter shows the statistical analysis for the informations extracted from the questionnaire. 250 invitations were send to persons who work in the Qatari building industry to take part in the study, bespeaking from them to give replies to the inquiries and besides to portion at that place ain sentiments sing the research subject. Number of standard responses were 79, with 8 uncomplete answered transcripts. The incomplete standard questionnaire were excluded in the statistical analysis because of deficiency of adequate informations, but the remarks which respondents added have been included in the decision.
The response rate was 31.6 % Generally, responses rate in the building industry are considered to be really low, because of the low involvement of people in the field toward scientific and academic researches, and besides could be due to the irrelevancy of the study topic to the respondents nature of work or involvements.
Q1: Respondents were asked to bespeak their period of experience in the building industry
Figure 5.1: Respondents professional experience
The chart in Figure 5.1 shows that 66 per centum of the respondents are holding between 5-10 old ages of experience, at the same clip for those who have more than 10 old ages of experience they represent 21 % of the entire responses, while the remainder are people who have experience but less than 5 old ages.
Result shown that 87 % of the sample have more than 5 old ages of experience in the building industry, which would give more believable consequences to the research consequences as these people represent the intermediate to senior places in the industry.
Q2: Respondent were asked to bespeak their occupation rubric
Figure 5:2 Respondents occupation rubric
Figure 2 shows that 61 per centum of the targeted sample have their occupation rubrics as ‘Engineer ‘ , that includes all specialisations of ( civil, mechanical and electrical ) applied scientists, every bit good as designers who are working in different proficient degrees except building and undertaking directors. ‘Construction directors ‘ represents 8 % of the sample, and the ‘project directors ‘ are 13 % . A little per centum of 4 % are from those who work as Quantity surveyors.
Reponses on the ‘Other ‘ option are 14 % of the entire responses, those identified themselves as working in the ‘Health and Safety ‘ sections, every bit good as some in the ‘Research and Development ‘ subdivisions.
5.1.2: Organizational Information
Q3: Respondent were asked to place there organisation ‘s occupation type
Figure 5:3: Respondents organisation type
In Figure 5.3, the chart shows that 44 per centum from the respondents are working in undertaking companies. Respondents who work in design and Consultation companies are 15 % , Developers are 11 % , Project Management companies are 7 % and who represent the client side are 3 % of the entire sample respondents. 20 per centum mentioned in the ‘Other ‘ option that they are working as Service Providers and others in the Electrical and HVAC systems providers.
Q4: Respondents were asked to find the entire figure of employees in there organisations
Figure 5.4 shows that the largest class with a per centum of 30 per centum of respondents are working in companies that employ between 100 and 500 employees, following comes the companies of more than 10,000 employees with 25 % of respondents are working at that place. Having 80 per centum of respondents work in companies with over 100 employee ( average figure to big figure of employees companies ) gives another description about the respondent companies, hence the consequences of the research will accommodate more the medium to big concern houses.
Figure 5.4: Number of employees in respondent ‘s organisation
Q5: Respondents were asked to place how long has the company been in the market
Figure 5.5: Number of old ages the company is in the industry
The old chart in Figure 5.5 shows that 55 per centum of the responses comes from people who work in companies that have been established and have been working in the Market for more than 20 old ages, respondents are working in companies have been working since 11-20 old ages represents 17 per centum of the entire sample. 24 % from participants companies of 3-10 old ages of experience in the industry.
From this chart it is indicated that the bulk of respondents -72 % -are working in companies that have been for more than 11 old ages in the market, which gives the consequences of this research more suitableness to companies of long experience.
Q6: respondents were asked to find the company specialisation
Figure 5.6: Type of work in the respondent ‘s company
The consequences in ( Figure 5.6 ) shows that 32 per centum of respondents work entirely in the Commercial and Industrial edifices sector, following come the companies work in public sector undertakings, with a per centum of 23 % of the entire responses. Companies that work in the different sectors and non specialized in a certain field represent 13 % of respondents engagement, in add-on to 6 % who mentioned their field to be in the oil and gas plants.
To increase the dependability of the research consequences and to acquire more specific findings, an extra inquiries has been send to roll up informations about the one-year turnover of the respondents companies ; because during the informations analysis it was of import to demo the fiscal state of affairs of respondents companies, that will be benefited in the make up one’s minding which sort of companies the consequences would be applied on, . From the 71 original petitions merely one did non answer, 2 have apologized that there direction see the fiscal informations to be confidential information and could non unwrap them, and another 3 replied that they do non hold the entree to the fiscal state of affairs of the company. The inquiry numbered as 6A: Respondents were asked to find the company one-year turnover ( $ ) .
Figure 5.6A: Annual turnover of respondent ‘s company in US dollar
This extra inquiry gave a better apprehension to the sample, as shown in figure A6 that people working in companies specialized in public undertakings, residential edifices, and commercial and industrial plants are companies achieve $ 250 million to $ 5 billion in the twelvemonth, with per centums 70 % , 82 % and 80 % severally. At the same clip these three classs represent 70 % from the entire sample ( figure 5.6 ) which leads to see the sample to be more representative to medium-size to large companies.
5.1.3 position on sustainable building
Q7: Respondent ‘s were asked if they agree that their companies are familiar with the green and sustainable patterns in building.
Figure 5.7a: Respondents sentiments about company ‘s acquaintance in the sustainable building patterns Figure ( 5.7a ) shows that more than 76 per centum of the respondents agrees that their companies are familiar with the construct of sustainable building patterns, on the other side a little figure of respondents ( 6 % ) disagree with it.
Figure ( 5.7b ) is the representation of the responses based on the participants companies class, the chart shows that companies work in the Residential Buildings, Commercial and industrial edifices and the Public sectors in order are the most familiar with sustainable building constructs, while companies specialized in the substructure works and those in Roads and pavings are the least familiar. Reason for that belongs to concentrate of sustainable building codifications and guidelines preliminary on the edifices sector, due to the assortment of stuffs, systems and constituent which are non found in other sectors.
Figure 5.7b: Respondents opinions how familiar they are with sustainable constructs.
Q8: Respondents were asked to place how familiar they are with the undermentioned constructs:
Figure ( 5.8a ) shows to what extent respondents are personally familiar with construct related to sustainable building, consequences indicate that:
72 % of respondents are familiar with CO2 emanations thought, and its negative impact, merely 4 % who indicate that they are strongly unfamiliar with it.
28 per centum gave a impersonal grade of acquaintance to the construct of sustainable building, while 64 % of responses are familiar.
Sing the rule of thin building, more than half of the respondents sample agree to be familiar with it, 25 % gave a impersonal response and 21 % disagree.
Figure 5.8a: Respondents sentiment on how familiar are they with sustainable constructs.
More than one tierce of the sample are impersonal in forepart of Qatar Sustainability Assessment System ( QSAS ) , and this construct represents the least acquaintance of respondents comparing to the old points, that merely 32 % indicated they are familiar with it.
Figures ( 5.8: B, degree Celsius, vitamin D and vitamin E ) are the replies for inquiries presented harmonizing to the class of specialisation.
Figure 5.8b: Respondents sentiment on how familiar are they with CO2 emanations and their impacts
Figures ( 5.8b ) shows that Residential edifices sector is the most familiar with CO2 emanations and its negative impact on the environment with 87 % of responses agree with that, so comes the public sector with 77 % agree and 75 % for the main road and paving sector.
Figure 5.8c: Respondents sentiment on how familiar are they with sustainable constructs
Figure 5.8d: Respondents sentiment on how familiar are they with thin building rules In the chart of figure ( 5.8b ) respondents in the commercial and industrial edifices are the most familiar with sustainable building construct, the ground as mentioned before because they are in touch with all sorts of codifications and specifications related to green edifices. In the class “ Others ” 67 % said they agree with the inquiry, this group are more interested in research and development sides. The least per centum is in the substructures sector with 46 % agree on the acquaintance with the construct.
Technical staff who work in the residential edifices and research and development subdivisions as figure 8.d shows are the most familiar with thin building rules, with 67 % of the agree with this inquiry, every bit good in the commercial and industrial edifice they represent 66 % of this class who are besides agrees with acquaintance. The least is the subdivision of Highways and pavings, although there is non many participants from this field, but the standard replies give 25 % agree and 25 % disagree.
Figure 5.8e: Respondents sentiment on how familiar are they with QSAS aˆZ0.1
Acquaintance of the sample with QSAS is less than medium, that merely 52 % of the respondents in public sector agree they are familiar with it, residential edifices and commercial sectors are merely 47 % and 33 % severally. Reasons for that would mention to newness of QSAS deployment since 2009.
Q9: respondents were asked to find if the sustainable patterns in building give more competitory advantage
Respondents sentiment about the relationship between sustainable building and competitory advantage The purpose of this inquiry was to happen the sentiments of participants about sustainable building patterns during the building stage and its relationship with accomplishing more competitory advantage for the company,
consequences in figure ( 5.9a ) shows that 73 % of the respondents agree that sustainable patterns in building are utile in giving the company more advantage among other rivals.
Figure ( 5.9b ) shows that the bulk in residential edifices and the substructure sectors agree that sustainable building patterns give more competitory advantage to the companies. And that refers to the new demands of clients in the private sector every bit good as governmental ordinances to give precedence of commands winning to companies which have old experience with sustainable building, or those which are interested to follow use it in new undertakings. people from the research field ‘others ‘ are the least of holding with this relation, it may mention to miss of cognition and experience about the building market
and factors of consequence.
Figure 5.9b: Respondents sentiment about the relation between sustainable building and competitory advantage
Q10: respondents were asked to give their sentiment about the complexness of sustainable building in comparison to the conventional manner of building
As shown in figure ( 5.10a ) , more than 54 % of respondents agree that sustainable building is more complicated to construct than conventional undertakings, 41 % have impersonal position sing the inquiry. One of the remarks on the same inquiry said:
Figure 5.10a: Respondents sentiments about the sustainable building complexness “ complexness and trouble of building a undertaking depends on the staff experience “ .
Figure 5.10b: Respondents sentiment about the sustainable building complexness
Figure ( 5.10b ) shows that people in the residential edifice sector are the most agree of the complexness of sustainable building more than the conventional edifice methods and patterns, they consider it to be like this because of the many facets that should be considered during undertaking executing, such as stuffs, environment, H2O aˆ¦ etc.
Figure 5.11a: Chart shows respondents
sentiment about the sustainable building budgeted cost compared to conventional building Q11: respondents asked to give their sentiment about the more cost of sustainable building than conventional building.
From figure 5.11a, it is shown that about two tierce of the entire responses agree with the thought that sustainable patterns in building cost more than the conventional manner. While 16 % disagree with that.
Responses from participants working in the roads and pavings sector are extremely holding ( 100 % ) with sing sustainable building cost to be higher than conventional building as shown in figure 5.11b, and that is one of the grounds that people are avoiding these patterns. The last class of people working in the research and besides service providers agree with it, because they are familiar with market monetary values specially for advanced and sustainable constituents.
The remainder of other sectors gave variant per centums, but about the same degree of understanding and dissension sing the sustainable cost is shown below.
Remark received from a participant:
“ initial cost would be high, but operational cost would be less “
Figure 5.11b: Chart shows respondents sentiment about the sustainable building budgeted cost compared to conventional building
5.1.4 Sustainable Practices in Construction Site
Q12: . respondents were requested to state if they agree that their companies are interested in utilizing recycled stuffs.
As shown in ( figure 5.12 ) 82 % of the respondents from residential edifices group agree that their companies are interested in recycling or recycling stuffs in the building work, following are highway and pavement companies. A expression to the commercial and industrial edifices sector gives the per centum of 61 % of those who agree. Disagreement came from substructures and general plants sector and that may mention to the less involvement from top direction, from “ others ” group 25 % disagree with the stuffs recycling due to see them as an office occupation than to be in site.
Figure 5.12: Chart shows respondents positions on the companies use of recycled stuffs
One of the remarks from respondents said:
“ Recycling of stuffs requires an unfastened minded direction, who understands the benefits of reusing/recycling of stuffs, and able to use the policy on the whole system in the organisation ”
Although recycling stuffs gives an advantage for the company in cut downing the negative impact on the environment, every bit good as decrease in the cost but recycling process in-site demands particular issues to be considered ; that containers for hive awaying different stuffs in certain points in the undertaking, and labours attempt to divide stuffs which leads to decelerate down the procedure of chief building work ( Lennon,2005 )
Q13: Respondents were asked to inform about utilizing local merchandises in the building
Figure 5.13a: Chart shows respondents positions on the companies dependency on local merchandises Figure 5.13a shows that 58 per centum of the sample agreed with the inquiry, their companies depends on the local merchandises. 17 % disagreed with it. From observation, the building market in Qatar depends by and large on the local makers for the civil plant, electrical and other systems are widely imported. Many respondents added to this inquiry that “ interior decorators sometimes inquire for certain stuffs and merchandises that local manufacturers does n’t carry through the specifications, which let contractors to happen foreign providers ” .
Respondents from different sectors positions about utilizing local merchandises
Figure 5.13.b: Chart shows respondents positions on the companies dependency on local merchandises
Roadss, Highways and Infrastructure companies are the most dependent on merchandises manufactured in Qatar, as shown in figure 5.13b, because most of them are available locally. Companies of general building works, HVAC systems, electrical and residential edifices need to hold imported contraptions for their plants
Q14: respondents were asked to bespeak to what extent they use lasting stuffs in the site.
As shown in figure ( 5.14a ) , 68 per centum of the responses agreed that their companies are utilizing lasting stuffs in their work, which means that they are funny about the life clip of the building and care work
Figure 5.14a: Respondents positions on the dependence of companies on lasting stuffs when needed. 4 % of the sample disagreed with it.
Participant besides mentioned the function of interior decorator in finding the specification and types of stuffs and systems used.
In figure 5.14b it is shown that about all the building sectors are interested of utilizing lasting stuffs, they normally have the contracts of defects and care liability for certain old ages after commissioning, which encourage companies to cover with lasting merchandises to be in the safe side. It is mentioned from the residential edifices side that some do non hold in utilizing them in their undertakings, this is may happen because for some residential edifices are wholly sold to the new dwellers and the building company is non responsible about the construction any more.
Figure 5.14b: Respondents positions on the dependence of companies on lasting stuffs
Q15: respondents asked to bespeak the chief grounds for energy ingestion in the building site
Chart of figure 5.15a shows that:
Respondents put deficiency of cognition in the first rank as a factor of high energy ingestion during the building, that 95 % of the sample agreed with it to be a chief ground.
Low involvement of top direction came following, that 82 % of respondents agree that it is a ground for the high ingestion of different signifiers of energy.
Remarks from participants: “ Management is ever forcing to complete before the deadline, and they are more tight to the clip agenda, energy issues lay in the underside of their involvements list ” .
Figure 5.15a: Respondents positions about the grounds of high energy ingestion
Although 10 per centum disagreed with sing no duties to be a ground for energy ingestion, but 76 % of the responses agreed with it.
A respondent commented: “ There are some duties that focus on protecting environment and safety safeguards, but non energy ”
The low cost of fuel and Fast trailing rules came about in the same degree harmonizing to respondents positions, where 59 % gave an understanding that the above points are grounds for high energy ingestion in Qatar, besides 32 % of them gave a impersonal reply.
The term low cost of electricity came in the last rank, half of the responses agreed to see it as a ground, 9 % disagreed.
Looking at responses based on the industry class:
Figure 5.15b: Respondents positions about the grounds of high energy ingestion ( Low cost of fuel ) Figure 5.15b shows that sectors of substructures, roads and pavings plants are extremely holding in sing the low cost of Fuel as a ground for devouring excessively much energy, that is because these companies work uses chiefly big figure of equipments that depend on fuel as a beginning of energy. while the class of “ others ” : research and services supply stand impersonal in the forepart of this factor to see it as ground for energy ingestion.
deficiency of cognition
Figure 5.15c: Respondents positions about the grounds of high energy ingestion ( deficiency of cognition ) was a factor that has been agreed about nem con from all participants. Figure 15.5c shows a per centum of 17 % of Others class do non hold with the point.
Figure 5.15d: Respondents positions about the grounds of high energy ingestion ( deficiency of direction involvement ) People in different sectors by and large agree with the deficiency of direction involvement to be a ground for more energy ingestion, the consequences are shown in figure 5.15d, respondents say that when directors are following a scheme of salvaging energy shared with all the staff it encourage the company to work under the same vision of directors.
Figure 5.15e: Respondents positions about the grounds of high energy ingestion ( fast trailing ) Highways and pavings sector agree that fast tracking causes higher energy ingestion, that it is due to the energy consumed in the dark clip working, where installations are required to increase the work velocity. Figure 5.15e besides describes that other sectors give a impersonal response to this point, either that they do non see a direct connexion between energy ingestion and fast trailing activities, or they do non fall back to it in their work.
Figure 5.15f: Respondents positions about the grounds of high energy ingestion ( Low cost of electricity )
Although electricity duty in Qatar is really low comparing with the international monetary values – between $ 0.01-0.02 /KWH harmonizing to belongings usage and measure of consumption- , but responses are between impersonal to hold with sing electricity low duty to be a ground for more energy ingestion. In figure 5.15f it is seen that commercial and industrial sectors are the most agreeable because they use many equipments and installations that depend on electricity as power beginnings during the building.
Rate of responses from different sectors that agree with looking at no duties to be a ground for higher energy ingestion is severally high. Figure 5.15g. Minority disagree explicating that it is hard to happen duties that force companies to salvage energy,
Figure 5.15g: Respondents positions about the grounds
of high energy ingestion ( no duties )
because there is no practical measurement for that, but some classs or guidelines that are held by the authorities or the private sector to increase the consciousness of people in the field is a better manner for energy economy.
Q16: respondents were asked to find if their companies implement policies to salvage energy during building
Figure 5.16a shows the grade of companies to organize salvaging energy policies in the building stage, around half of the respondents agreed their companies depend on it, but at the same clip one 3rd differ toward this action.
Figure 5.16a: Respondents positions on the execution of policies to salvage energy during building
Associating this portion with the old in inquiry 15, figure 5.16b shows that around 60 % of respondents working in undertakings for public sector and industrial edifices are holding more inclination to work under a policy for salvaging energy. Another observation related with the companies turn over and this pattern, it is found that the larger the company with higher bend over the more it is interested to hold the energy economy program.
Figure 5.16b: Respondents positions on the execution of policies to salvage energy during building
Q17: respondents were asked to find the companies use of Renewable Energy beginnings
Figure 5.17a: Respondents positions on the execution renewable energy beginnings in building undertakings.
As antecedently mentioned in chapter 2 that the national development scheme in Qatar for the period between 2011-2016 is endeavoring to broaden the dependence on renewable energy beginnings in the state, and although it encourages stakeholders to put more in this side by holding more installations, but study consequences did non reflect positive tendency toward that. Figure 5.17a shows that:
One tierce of the sample agreed they are utilizing air current turbines as a beginning of alternate energy, but a larger group of 40 % disagreed with utilizing it in their undertakings.
Although the Sun is one of the most of import beginnings of energy in Qatar ( norm of 16 cheery hours/day ) with clear sky most yearss of the twelvemonth, but respondents agreed they depend o solar systems were merely 27 % of the sample,38 % disagreed with the point, and the same per centum gave the impersonal reply.
Hydropower and Geothermal came in underside of the list, 62 % disagreed of utilizing geothermic system, and 64 % disagreed with utilizing the hydropower.
Remarks from respondents mentioned the tie energy power, which is used in the new undertakings near the cost, and specially in the “ Pearl unreal island ” in Doha.
Residential edifices and roads plants companies are more familiar with utilizing solar energy during the stage of building, this energy generated by solar panels is exploited in bring forthing electricity to feed the offices and in-site adjustments, as shown in figure 5.17b.
Figure 17.b: Respondents positions about utilizing solar energy in building undertakings
Infrastructures companies are the least user of solar energy, that may mention to the nature of building site layout in the substructure undertakings, where they normally need big empty infinites for stuffs roll uping, and equipments steering and parking.
Figure 5.17c: Respondents positions about utilizing air current energy in building undertakings
Exploiting air current power energy is really low in the building undertakings in Qatar, figure 5.17c shows high per centums of respondents who does non utilize this beginning of power in their undertakings, because air current energy needs particular contraptions of air current turbines that requires specializers in installing, care and operation, and that is non so available in the state. secondly building undertakings are normally fast and impermanent, which will add excess attempt on the technology houses to see the air current energy as an option in the in the site.
But it is shown in ‘others ‘ class that many respondents uses the air current energy, it would be mentioning to the oil and gas undertakings, as the companies are responsible about operating in some instances, which let them be interested in using different options for power beginnings.
Figure 5.17d: Respondents positions about utilizing
hydropower energy in building undertakings
As motioned in the break of figure 5.17a there is no high demand on the hydropower energy in Qatar in general. The lone applications as seen in figure 17.d are in the oil and gas sector, because they have lasting Stationss inshore near the seashore, or out shore inside the sea, and they try to work the trussed energy but in a narrow field.
Figure 5.17e: Respondents positions about utilizing geothermic energy in building undertakings
From figure 5.17e it is really obvious that geothermic energy system is non widely used in the state, some respondents in the undertakings of public sector and service providers agree with utilizing the geothermic system for chilling, in add-on to really few undertakings in commercial sector.
Figure 5.18a: Respondents positions
about surveies for equipments
demand done before get downing the undertaking
Q18: Respondents were asked to find if the companies study the matching between equipments and the occupation demands.
As shown in ( figure 5.18a ) that 68 % of responses agree that companies make a survey of the needful equipments for the building work or any needful equipments, that match the work nature and demands. Merely 7 % of the responses mentioned that their companies do non take this action.
Figure 18.b: Respondents positions about congruency between equipments and the occupation nature.
As the main roads and roads companies depend fundamentally on the equipments to accomplish their undertakings aims, so people from this sector give the full understanding of doing this survey before the undertakings start. Figure 18.b
220.127.116.11: Human Aspects
Q19: Respondents were asked to clear up if they agree that their companies train employees on sustainable building patterns.
Less than half of the sample agree that their companies give developing on sustainable building to the employees. From figure 5.19a over than one 3rd give impersonal reply, they commented that they receive some formal correspondences which ask employees to pay attending for certain patterns related to sustainability, but considered to be nominal and unserious counsel.
Figure 5.19a: Respondents positions about employees developing held by companies in the sustainable building constructs.
By looking to replies based on companies classification, figure 5.19b shows that substructures companies are the least interested in developing their employees. The companies specialized in public sector undertakings are divided into 37 % agree and 38 % disagree. Residential edifices are the most interested in this preparation, linking that with the reply of inquiry 9 about competitory advantage, it is obvious that companies in this field believe that sustainability in building is a manner to make better competence in the market. Peoples who work in Oil and gas companies and others in research and development sections give positive to impersonal replies comparing with others.
Figure 5.19b: Chart shows respondents positions about employees developing plans held by companies in the field of sustainable building
Q20: Respondents were requested to state if they agree that their companies offer clean and healthy work topographic point
One of the faces of societal dimensions in sustainability is the ambiance at which employees are populating in their day-to-day work, and the workplace good health and cleanness is measured and consequences are in figure 5.20. Roadss and pavings companies are the least healthy and clean workplace among others, respondents commented that it is due to the flaxen environment of site locations, and normally they have nomadic trains for site offices to travel them easy in the hereafter, that will non assist to happen the clean topographic point. All other sector attention in the workplace to a point, harmonizing to the site conditions, companies size and working staff.
Figure 5.20: Chart shows respondents positions about the work topographic point cleanness and healthiness the companies offer
18.104.22.168: Waste Management
Figure 5.21a: Respondents replies about holding a waste direction program in the undertaking
Q21: respondents were asked to bespeak if they have waste direction program issued in the preconstruction stage
( Figure 5.21a ) represents 73 % of participants agreed that they have a waste direction program that has been issued in the preliminary phases of be aftering to the undertaking.
Figure 5.21b shows that companies who have a waste direction program for the building site varies between 73 % – 83 % of the respondents from each class, except the companies of substructure plants ; respondents give 71 % that they disagree of holding the program.
Figure 5.21b: Respondents replies about holding a waste direction program in the undertaking
Q22: Respondents who agreed of utilizing WMP in work ( question 21 ) were asked to inform the committedness of the company to use this program.
73 % signifier the whole sample participated in this portion, as shown in ( figure 22.a ) 57 % of them agree that the waste direction program is followed in the building site, and 27 % give the impersonal reply.
Figure 22.a: Respondents replies about holding a waste direction program in the undertaking
In figure 5.22b it is shown that the main roads and paving group are the most committed to the WMP application, it may mention to the fact that figure of activities and stuffs in the roads building site are so small comparing with the other building sectors, which gives the site direction degree better chance to give excess involvement to the waste stuffs and a better alteration to work it in expeditiously. The remainder of the sectors are demoing assortment in following WMP in world, with a grade of disagreeability in the sectors of ( Commercial, Residential and Public ) , the ground for that is the deficiency of cognition or equipments to pull off the waste, which means WMP are formed without measuring the existent capacity of the undertaking.
Figure 5.22b: Respondents replies about holding a waste direction program in the undertaking
Q23: Respondents were asked to clear up if technology squad make frequent alteration or alteration to programs that lead to minimise wastes
Revising programs to minimise building waste is more occurred between edifices building site squads than others in roads and substructures Fieldss, that is shown in figure 5.23. The thought behind this fact that for edifices it is easier for interior decorator or builder to happen different options and solutions for a certain point, assortment of systems, stuffs, dimensions every bit good as map of usage. But that is non the same in the substructure and roads undertakings, at which really sight alterations in specifications or stuffs are occurred due to the restrictions of options.
Figure 5.23: Respondents replies sing programs alteration to minimise waste.
Q24: Respondents were asked to bespeak the handiness of steps to H2O ingestion in the undertakings
Figure 5.24a shows that 74 % of respondents agree of utilizing H2O ingestion control systems internally: offices lavatories and adjustment, but sing the site the per centum is lower, where 60 % agree with.
Figure 5.24a: Respondents sentiments about
H2O ingestion measuring in building site
Figure 5.24b: Respondents sentiments about utilizing H2O ingestion steps in building site internally
General building works group are the most applying H2O ingestion steps in the internal environment of their undertakings. As figure 5.24b clarifies, other groups have besides the same pattern but in a lower degree.
The external environment ( in-site ) pattern is less focussed sing this public presentation. Figure 5.24c gives respondents positions which are majorly limited between agree and impersonal sides.
The ground for that is the more trouble in commanding and less forming of the building site, although some companies determine certain points for H2O supply, but workers and subcontractors chiefly care about completing the undertakings faster without paying attending to other groups or ordinances, hence they create other unorganised ways for utilizing H2O. The other job in this point is the H2O consumed for dirt suppression, this is an unmanageable operation which consumes large sums of H2O to cut down dust consequence.
Figure 5.24c: Respondents sentiments about utilizing H2O ingestion steps in building site externally
Q25: Respondents were asked to advert if some certain patterns are taken topographic point in their companies.
Respondents in different building sectors gave about close degree of agreeableness on this quest ion, so the description will non demo each individual class ain replies individually. Figure 5.25 shows that:
62 % of respondents agree with using patterns that do non harm the biodiversity around the undertaking, 37 % give impersonal reply to the point with a remark that many large companies working in the oil and gas field, substructures and main roads put to deathing at that place work in the desert.
Some stuffs wastes and packaging are burned in the site alternatively of direct them for recycling ; which contains harmful air emanations. Merely 7 % disagree that their companies prohibiting this pattern.
75 % agree that their companies normally do non depend on toxic or risky stuffs in their undertakings, the remainder of 25 % give impersonal response.
Figure 5.25: Respondents replies on some patterns occurred in their undertakings that minimize negative environmental impact.
Covering some stuffs in the site is common between the sample, 78 % agree of holding this public presentation in their undertakings, which helps in cut downing the dust comes from littorals, cement and any other stuffs.
85 % of responses agree with testing the site to halt dust distributing. As mentioned in ( inquiry 24 ) normally H2O is used to command the sand suppression.
Q26: Respondents were asked to inform if the company set up ecological study for the site before building.
Figure 5.26: Respondents positions on holding ecological study for the site before building.
Figure 5.26 shows that sectors of main roads and substructure plants are the highest applicable for ecological study before get downing the undertakings executing with 100 % and 80 % severally agree from participants in each class, the residential edifice subdivision is the least with merely 45 % of the respondent in this sector agree with the point. The consequence may mention to the location of the building site, residential edifices are normally in the inhabited countries, and occupy little country comparing with roads and substructure undertakings, which may widen long distances inside and outside metropoliss, that requires more logistic readyings in different sides.
22.214.171.124: Transportation system
