Crisis of Harpharzard Neighbourhood Development in Lagos-Ogun State Megapolis, Nigeria

Crisis of haphazard neighbourhood development in Lagos-Ogun State Megapolis, Nigeria.

Introduction
The principles and practice of physical development planning in modern economy of towns and cities have set goal and objectives of achieving functional, economic and aesthetically pleasing built environment with little or no friction of pollution, urban infrastructure, decay and failure, traffic congestion, flood insecurity and health hazard.
This organization is known as the process of comprehensive community planning. It has four basic stages of statement of goals and objectives, basic research into problem identification, plan preparation and plan implementation.

A cursory examination of the case study of mega polis of Lagos and Ogun State suburb development reveals so many things that are left to be desired. Virtually at every stage of planning process. There has been a devastating deviation from the acceptable norm that has helped the developed world deliver optimum built environment.

From the Lagos end of the mega polis, emphasis has been so much on implementation without strict adherence to the Master Plan and Urban Renewal Plan. For instance it's a common place in Lagos, Nigeria to see planning agency granting approval for a redevelopment of an old site with old structure on it- even a family house- in a city centre. Such approval may be granted for a commercial building without any mitigating action on parking, noise refuse and waste disposal. Yet at the office the approval contains fictitious Environmental Impact Assessment (EIA) document supporting such development.

From the Ogun end of the mega polis the problem is more acute because it is not only occurring at the implementation stage but abinitio from the first stage of the process. No formal definition of goal and objectives for development at the special arrears such as zone sharing boundary with Lagos metropolis. No basic studies conducted. No Master Plan at least to the public knowledge, and where they exist no public participation or awareness and no urban renewal policy or plan.

Implications
Considering the flow diagram as shown above, it can still be observed that some efforts were made gearing towards implementation of some plans that must have been made in the past, such instrument is the old western Region " Town and Country Planning Law cap 123 of 1946- a classic example of building and housing codes and Land development Law (Roads) 1948 cap 106- which is a classic example of subdivision regulation. Another land instrument though not a planning implementation tool , but with planning implication is Land Use Decree of 1978, which is a classic example of Land tenure and reform instrument. In a major effort to develop modern uniform implementation tool, the federal Government enacted Urban and regional planning Decree 1992, which later transformed to an act of parliament. Various agencies at different level of government are charged with the responsibility of implementing the provisions of these above laws and instruments.


However, a cursory observation at the physical environment of our case study reveals environmental menace such as flood, traffic congestion, substandard structures, awkward road layout, power supply inadequacy, refuse disposal problems, drainage problems, housing shortage, pollution among many others like dearth of public services like schools, and hospitals.


A case of temporal distribution problem of traffic in Lagos Mainland Nigeria (Peak Period Traffic Congestion)


A case of severe flood in the peak of rainy season in Ogun State Suburb, Nigeria.
The question now is why we are having these problems.
In the first place it cannot be clearly affirmed that the status quo of planning process in Nigeria generally is as comprehensive as expected to be. The present states depict a one on one approach from various government administrations. No planning agency clearly engages in the process of formulating acceptable goal and objectives for future development within their planning jurisdiction.
Basic Studies. This stage of planning has suffered a severe setback, even with the advent of information age. Planning Research Institutions have been suffering from underfunding. The entering into the league of satellite launching country of Nigeria has not rightly made available planning data, policy and laws publicly available on website where such information can be easily accessible by the public. The basic planning data are not easily accessible to even professionals in built environment let alone members of the public. The main problem has been either no study or research has been conducted or the findings of such where they have been conducted are not publicly accessible. Major research parastatals either don't have website or information are not obtainable from their public domain. The concept of data "data bank" is still an ideal rather than a reality in Nigeria after more than two decades into information age. It is not a shocking
revelation to discover that agencies of planning research and planning implementation still run a flat file database system which has not even been digitalized. A simple form of relational database system of MS Access is not popular among many research institute. Even such big institutions like university have not digitalized their exams and record database system.
Plan Preparation: This stage too has suffered major neglect by successive administration in the two state of study. From Lagos end some plans were made as far back as 1946 during the colonial era. Also some urban renewal plans were also developed. The problem here again is that they were not reviewed at the end of their life cycle and new ones were not developed to guide the development of on the fastest growing mega polis in world. Rather Lagos government resulted to scheme development approach- a system of creating a prototype ideal neighborhood development project which is against the system nature of towns and cities. The scheme development approach is supposed to be a make shift solution and not a sustaining, permanent and comprehensive approach to development planning. The scheme development gave birth to various government residential estate such as Lekki, Victorial Garden City, Park View Estate, Magodo , Ogudu Ikeja, Omole, Jakandes and many
others. However, as we can see today, they constitute island of prosperity amidst ocean of poverty scenario across the city. Also the attendant traffic congestion that has resulted from these various schemes lends credence to the failure of this approach. The public infrastructure such as power water and waste disposal system failures are indicators of failures which are prevalent in these housing estate as a result of their inability to connect harmoniously which the rest of the city. Another problem emanate is the negative impact these schemes are having on the rest of the megapolis. Some of them constitute night desert syndrome- a condition of absence of night street activities which is causing security issues for the neighbouring community, some generated a lot of social unrest in matters relating to land acquisition, other are flood and solid and domestic waste polluters of nearby communities.
From Ogun State end the plan preparation activity seems to be in non- existence. Industrial scheme development was an impulsive response to the industrial need trend and spill over from Lagos State. The absence of plan preparation of the neglect of the state thereof are evident with spill over growth being experience along Lagos-Ibadan express way and Akute-Ijoko axis which has now come under rehabilitation and reconstruction.
Urban Renewal:
This is a comprehensive action plan directed at improving and rehabilitating decayed and obsolete district of a city. From Lagos end, urban renewal efforts have majorly dependent on successive administration. Various disjointed sections of the city depending on political will of the government of the day have been attracting investment towards city renewal. However, in the last six years of the present Lagos State administration, wide spread efforts that were devoid of selective approach were deployed to overhaul the infrastructure of the city. Road expansion projects, rehabilitation and improvement were embarked upon. Ikorodu axis, Lagos Badagry, Oshodi road terminal are examples. Massive Landscape improvement along major highways are noticeable. Major decentralization of major land uses such as markets . A remarkable feature of this effort is that it cuts across every section of the state irrespective of the importance or social status. However, it
brought so much hardship on the city population because it lacked a long term approach injected into it. Its implementation was hurriedly conceived without adequate formulation of goals and objectives, hence its social cost was enormous on the city dwellers especially the less privileged ones.
From, the Ogun State end, there was a devastating and reckless "do nothing" approach in the aspect of urban renewal even in the state capital- Abeokuta. The previous administration for more than a decade, allowed the infrastructures in the state to decay without any effort to improve especially in the areas sharing boundary with Lagos State, obviously for political and other selfish reasons. The areas were allowed to grow without proper development control because they were under grossly incompetent and ill-equipped local planning authorities jurisdiction e.g Ifo, Wawa, Agbado, etc. Encroachments on major acquisitions of both federal and state government are common place in these areas. Neighbourhood plots are majorly allocated by land speculators without any professionally prepared or approved layout plans. The scenario has got to the extent that even state government locates educational institutions on highway reservation and sites liable to
flood. Traffic within neighborhood can last as long as three hours in some cases e.g. Alagbole-Akute road.
However, there seems to be emerging some relieve with the advent of the present Ogun State administration in aspect of urban renewal. Major highway expansion projects are now being undertaking to the satisfaction of independent reasonable observers.


Plan Implementation. From Lagos end, the first culprits is lack of political will to implement plan provisions. This particular situation has resulted to activities of land speculators popularly known as 'omo oniles". These particular interest groups of the society are the native family title holder who has constituted themselves to local illegitimate authorities in land use and land title allocation. This menace cuts across the nation, but assumes an horrible dimension in Lagos and Ogun State. The origin of this mischievous dimension can be trace to Lagos, when after the federal capital territory status was move to Abuja, the family title holder who had lost their land to federal government acquisition approached the state government for their release. The state government granted such release with government gazette and some families even obtained legitimacy for their land by registering them to obtained Certificate of Occupancy in a company name.
These families no longer have recourse to obtain an approval or register their subdivision or layout plan before they begin to sell. As a result land development became haphazard and without any relationship with the overall development plan of the community. Standard practice of T-Junction, cul-de-sac, pedestrian walkway, sloip, setback, radial plots, lay-bys among many other standard subdivision practice that can yield functional and aesthetic neighborhood became things of the past. So many common sense land layout have produced awkward shape, narrow road close, drainage trap T- junction among many other ugly feature.

CONCLUSION AND RECOMMENDATIONS
Government needs to be reassured that planning function remains one of its major responsibities to the public. Government should not just see planning duties from revenue generation point of view only but from angle of social responsibility.. Hence, government needs to be alive to its responsibility.
Government needs to adopt a comprehensive development process approach to environment issues.
The four basic states of development planning process should be fully funded and practiced. The shortcut unscientific, one-to-one approach has not yielded dividend in the past and will not in the nearest future. We have the model of emerging economies such as Singapore, Malasia, South Korea among others to follow. Human settlement is just like human body, it must be formed first before we can put cloth on it for decoration. Decoration alone doesn't make a lady a beauty queen. Lagos and Ogun should know that construction is just a form decoration; development planning is what forms the body a town.
Activities of land speculators should be checked. No interest group should be above the law and the public interest.
Regional development policy to correct the imbalance growth across the nation should be given a pride of place. This is necessary to check the rural urban drift and overcrowding at the city centers.
The public need to be educated in matters related to real estate investment. There is need to understand prospects and constraints, when it comes to development potentials of land vis-à-vis returns in such investment. Some huge investment being made by members of the public in real estate are not as feasible as they are perceived. Such bullish trend on land and landed property attracts sharp reaction from supply end and results in sharp practices on the part of government and land speculator

50 ways to execute your building construction project at 40% reduction on conventional cost estimate

For overall project management use professionals with multiple backgrounds and bias within environmental field, or the ones who are qualified in one discipline but has bias or experience in other related fields, especially when you are looking for project manager .e.g. planner-architect, architect-engineer, estate surveyor-lawyer e.t.c especially the one who is in to project development management with at least 10 years of experience. This may help reduce consultation fees.
Visit the site with development consultant to know development implications of the land before you purchase.
Visit your proposed site during the peak of raining season or extreme weather season applicable to your geographical location to understand the condition of the site in such situation
the site is rapid slope make sure it is towards road direction except if the land is a corner plot bounded by two roads forming a junction
Visit the site independently to interact with the social environment and pick up any rumour concerning the ownership rights and disputes on the land. This is important if you are residing in developing world.
if you can use measuring tape, measure the land by yourself
You can get a government official in charge to help confirm if the land is free from government acquisition
if the land has a master layout plan sheet ask for photocopies
Upon completion of transaction on the land immediately take 1st step towards physical possession get your surveyor to put beacon pillars. If you can't afford a surveyor do it your self (it may not be accurate, yet it can be adjusted by a trained expert later.
10. Take second step of physical possession after the accurate dimension and orientation of the land is settled, by erecting dwarf "four corner" wall, physically demarcating the four points defining the boundary of your land
if you are digitally learned you can use the GPS feature of your smart phone like blackberry to know the geo-reference co-ordinates of the four points defining the boundary of the parcel of the land.- this is usually in longitude and latitude, however it can be converted to UTM format which is the industry standard. This can help in having access to so many web based cheap and free land information services.
Try and do the necessary title documents if you can afford it.
If you can't the best form of security on the land is physical possession.
If you can afford a survey do it and get registered with land information obtained on the land to ascertain if its free of any government acquisition
A further step into physical possession is to offload gravel or any other material that is not easy to evacuate. Such as blocks, granite and sand
When you want to start building operation, target at least backfilling stage of foundation.
Start during dry season, if the fund is limited; wait until next dry season to continue.
Before you start, write down your brief on the type of house you want and review it with your spouse and siblings.
Give your brief to your consultant design professional.
Be modest concerning the size of the building.
Be futuristic in your approach
Engage the service of 3d computer graphic modeling of your building project. It shall enable you understand and give a clearer picture of the proposed building project and avert wastage in terms of incessant cancellation of already erected structure.
Think of the possibility of converting the house to investment asset in the distant future.
Engage the service of professional at the foundation stage if you are building story building, and this also applies to the construction of the upper floor slab (decking) in story buildings.
Use direct supervision at the finishing level if you cannot afford professional.
get a rough idea on construction if you cannot afford the comprehensive cost estimate. Get cost idea on the stage you want to embark on e.g. foundation
Do not stock pile large quantity of cement that you are not going to need within a space of three months maximum.
If you have a secured space for storage you can buy materials such as sand granite, gravel, iron rods, tiles in large quantities
If available use the services of artisans with multiple bias and skills e.g bricklayer-tiler, carpenter-furniture-maker
Engage worker will directly do the work and not the one acting as an agent who will contract the job out.
Use 10mm iron rod instead of 12mm for your lintels (provided the window span is a standard one). The 10mm iron rods are more in quantity per ton (133nos). Lintels do not bear much load.
If you can get a good carpentry workmanship, you can make use of "fairly used" wood but not "spent out" wood, for pillars and lintels construction.
Engage artisans on recommendation of your consultant or close associate.
Insist that the formwork (wood used to contained concrete) be removed before it sets (solidified) and redress the deformation, this will save you undue cost at the plastering finishing stage and ensure delivery of good job.

Get the service of multidisciplinary outfit to do your construction building project management.

While the work is still in progress pebbles, broken blocks, rubbles are all reusable materials don't evacuate them from the site.

It is cheaper to get the floor levels accurate at substructure wall levels, rather than at floor slab level.

Insert every pipes for openings in the concrete before concrete casting work. It saves labour cost on concrete breaking.

Use smaller size of brick/block such as 100mm,150mm for non- load bearing wall. Use can use it throughout if you are contemplating a frame structure, a technique of supporting all the load of a structure with an integration of columns (pillars) and beam.

If you want to procure your building materials yourself from manufacturer, go through an accredited dealer of that manufacturer and ask for discounts. Else, you may be buying at uneconomical retail rate.

The relationship among three major factors affecting project management namely (1) cost (2.) time (3.) Quality must be balanced. IF Time is over- shortened THEN quality may be compromised ELSE cost may have to increase.

Be moderate in terms of the option you choose for finishing. Of course there many options.

Use cheap and alternative structural materials such as gravel, sand etc. for construction of non-critical load bearing element of the building, such as non-load bearing floors. Lintels, window hood etc.

Use high quality pressure pipe for all conduit pipe work and minimize joints and elbows designs.

Relate the design of the house to site, in terms of shape of the land, natural slope and natural habitat. Do not attempt to inject drastic change to the natural feature of the land.

Use DPM material to control damp, instead of very thick layer of expensive materials such as concrete and sandcrete.

If the site has constraints such as low bearing capacity, swamp, slope etc, consult qualified, talented and experienced professional, else refrain from extensive and unnecessary consultations.

Look out for site prospects, such as gentle slope toward public sewer, or access road, firm soil with high load bearing capacity, existence of valuable construction materials on or around the site such as laterite, sand , rubbles , stone rock trees etc.

Look out for economy of proximity in material procurement.

Allow for spirit of team work and the workers of various category.

BE courteous and considerate with workers

Importance of 3d Modeling Construction In Project Conception and Execution







Project conception stage involves taking brief from development imitator or client. It involves taking brief from development initiator or client. It involves processes of information gathering that ranges from psychological data, financial data, personal data, socio-economic status, socio-cultural and many more depending on the scales and the size of the project in question.  Furthermore, the process involves assisting the development initiator in evoking the picture of development. The general aim is to help development initiator identify their development need and use it to create development product custom designed, evaluated and implemented to address the identified need problems.
In practice, most times the development initiator/client cannot effectively evoke the clear picture of what they want, hence they usually overestimate or underestimate their areas of development needs.
Moreover, when a proposal is finally drawn up the development initiator don’t immediately grasp every aspect of it no matter the length of time given to carry out such assessment.

This situation in most cases lays foundation for most conflict in development project contract execution especially in the private sectors. Most presentation drawings as required by regulatory agency such as planning authorities are required to be done in  2 dimension. This has implication on the development initiator who most of the times are laymen as such lack trained ability to interpret orthogonal projection in two dimension. This has implication of urban design as most site plan do not relate project to the immediate environment in three dimensions.

                 




Also environmental challenges can emanate such as flood and visual intrusion are occasional if detail ground modeling are not articulated in landscape and engineering projects.

Three Dimension modeling is the science and art of creating real life impression in presentation of development proposal. It is a way of mimicking the interpretation of brain eye combination of human beings. Ii can be done as physical paper model or as computer model. The physical model is most appreciated because it is most understandable, its real, it can be used for launching and fund raising purposes. It can assist project initiator in monitoring development process. However, it can be time consuming to create and more costly. Also the internal layout and details of the project may not be represented.

 
 
The recently popular one is the computer aided graphic model. The advancement in computing technology in recent time has led to the emergence of graphic modeling. Software are very much available in various application in engineering, entertainment, arts, and of course in built environment or construction development projects.
 
As a matter of fact, the only difference between the physical model and the graphic model is that graphic model is not tangible in 3 dimension. However the graphic model has advantage in the area of the time of execution and ease of duplication.

A unique advantage is the ability of presenting different section of the project in three dimensions. A dwarf wall in plan view can be perceived to be the same height with other high level wall. But with three dimensions the difference in height becomes obvious.

Project specification and job description can be made apparent devoid of controversy among the project contract parties.

Material scheduling can be made precise without miss-ups.
Quality and standard specification can be articulated and become a referenced document.

Conclusion
Project brief and consequently project conception can be well articulated with the aid of three dimension modeling.

Housing/Home Need Identification








House/Home is more than a shelter
·         It must meet all universally acceptable standard
·         It must meet its peculiar locational requirement
·         It must be customized in design and construction
·         It must reflect the peculiar
·         It must reflect the peculiar psychology of the occupants
 





House is a building that is constructed for residential purpose. The general tendencies among would be home owners is to erect a dream house whenever they intend acquiring a home either through mortgage purchase or self-development. However, in most cases would be home owners either over estimated or underestimated their need vis-à-vis their budget limit, which in most cases culminated to project dispute, huge debt burden and abandonment of home projects.

 
Five Living Needs Area

The following are the basic five living need o a couple
1.      Food Preparation
2.      Dining
3.       Living and recreation(indoor)
4.      Bathing-Laundry
5.      Sleeping

All the above activities need to be accommodated depending on the size of the family. The rate at which the size of the space required to accommodate the afore-listed  need change (increase or decrease) depend  on the phase of the life cycle of the particular family.
If the family intends to have three children maximum we can watch out for the following scenario.

At first the family is made up of a man and wife the need in the five areas above may be contained in a sleeping area a bath, a living area basically. Then at the arrival of the first baby. There may be need for a storage area and imminent need for extra sleeping area. At the arrival of second child the all the five areas of living needs shall be needed. At point the family living need shall remain stable for a long time until the next phase of the life cycle. The phase when the first family leaves home, it shall bring about decreasing need in the house because the family size is reduce to four persons.

This shall continue till every child leaves and the family return to original starting point of two persons. The last phase may be when, through death one of the spouse leaves, then the need are less than it was at the beginning.
