Construction of District Hospital project in Nigeria by Limult

Hospital construction projects pose extremely complex managerial problems. Recent government reports have been scathing in their criticisms of the unacceptable delays and cost increases in the delivery of new hospitals. The problems that hospital project managers face are particularly acute during the early stages of the project when the detailed user requirements are being established.

Many of the problems that develop later in the project can be traced back to a lack of attention given to the early stages of the project. It is in these early stages that the project manager has to reconcile the many disparate and often conflicting demands made by the multitude of user groups, funding bodies, government departments, estates maintenance departments and project consultants.

Hospital development characteristics

One of the most striking characteristics that distinguish hospital projects from other project types is the time scale over which they occur and the large costs involved. It is common for total costs to run to many tens of millions of naira and for total project time scales to reach ten to fifteen years.

When these types of time scales are compared against the average human life of seventy years their significance becomes apparent. Technologically, hospitals are also likely to be highly complex requiring the integration of diverse and intricate building services.

Functionally they are equally complex, having to satisfy the disparate demands of the general public and the highly trained staff that operate the facility. The functional performance requirements are such that the quality of construction has to be exceptionally high.

Construction of Road Project in Nigeria by Limult

Road construction involves the paving, rehabilitation, and reclamation of degraded pavements in order to achieve a state of good repair and increase road traffic safety. Construction of road involves the use of asphalt, liquid asphalt, concrete, soil stabilization, rebar, paving and pavement recycling machines, and other road repair materials.

Road construction projects are expensive and highly affected by uncertainties related to factors such as weather, type of soil and other site and environmental factors. These uncertainties impact on the accuracy of predicting resource productivity and developing reliable schedules for earthwork operations.

Current simulation and planning approaches and tools not only lack the capabilities of dealing with such uncertainties but they also lack the integration and intelligence to simulate multiple strategies – a model should be built every time a new scenario is required. As a result, planning decisions regarding the assignment of resources are purely based on planners experience and project plans are not the outcomes of comparing various allocation strategies.

The Steps To Starting A Road Construction Project

Concept Planning and Funding

Before any type of road maintenance or construction project can begin, industry professionals must receive the proper plans and funding. During this phase, the local government raises the notion of building or fixing certain areas. Then, it raises money in case of approval. The government will choose a construction company for the task and ask them to develop blueprints for the project.

Environmental Review and Inspection

The next step to starting a road construction project is to conduct an environmental impact review and overall inspection of the proposed job site. This is to assess the amount of damage posed to the environment during the course of the project, and whether the result is worth the risk. If given the go-ahead, those in charge of the project are required to perform a full inspection of the site to check whether it aligns with the project plans.

Job Site Preparation

Once everything is inspected and approved, it’s time to start preparing the site for the actual construction process. This often involves acquiring the proper equipment, establishing a construction zone lighting plan, and contacting material suppliers. For road projects, the government may hire professional flaggers to block off the construction zone and properly direct traffic. These are the best methods to ensure maximum safety for both workers and passing drivers.


Only after all of this planning and preparation can construction officially start. Depending on the type and scale of the work, the old road may be removed and repaved with fresh asphalt. Road work may also require fixing broken electrical lines or even water mains that run underground. Each project will be different, so the planning stages are crucial in ensuring that all problems are addressed.

Construction of Bridge Project in Nigeria by Limult

Much planning for bridge construction is required as it has huge impact on life of people. Social, scientific and technological dimensions for bridge construction must be considered. The decision of providing a bridge across any barrier is to facilitate the community residing on either side of the project. Some major bridges bring benefits to the whole country.

Building a bridge is a complex undertaking requiring knowledge and expertise. Several variables, including engineering constraints, costs, and environmental impacts come into play when deciding which construction method to use and bridge type to build.

LIMULT has experience with a wide variety of construction methods, from repairing historic cast-iron structures and masonry arches, to erecting modern steel-girder and concrete bridges. Whether building an overpass for greater traffic efficiency, a pedestrian bridge to connect two communities, or a signature bridge that will inspire a whole city, we understand the importance of working closely with local road and infrastructure engineering companies, agencies, and contractors.

Planning Sequence for Bridge Construction

The planning sequence for the construction of a new highway or a railway project is a major part of the project planning. Based on the complexity of the barrier across which the bridge must be constructed, the detailing of the project planning increases, because more investigation must be carried out. In general, the major steps that are involved in the planning for the construction of a new project is mentioned below:

  1. Identifying the need for the bridge
  2. Assessment of traffic possible and required in the area proposed to construct the bridge
  3. Study the location
  4. Study of all possible alternatives
  5. Refining and short listing all possible alternatives
  6. Identifying conceptual plans for the alternatives. This involves finding the materials, the arrangement of the span and the form.
  7. Preliminary design and the cost estimation
  8. Evaluating the alternatives, its risk and the final choice of decision
  9. Resource source identification by detailed surveying
  10. Implementation with the help of bidding documents. This is followed by carrying out by fixing the agency, the construction details, and their commissioning.

Limult Limestone Mining and Processing Factory in Nigeria

Limestone is composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced is either limestone or dolomite. As a source for lime, it is used to make paper, plastics, glass, paint, steel, cement, carpets, used in water treatment and purification plants and in the processing of various foods and household items (including medicines).

Limestone is a rock with an enormous diversity of uses. Most limestone is made into crushed stone and used as a construction material for road base and railroad ballast as well as an aggregate in concrete.

Some additional but also important uses of limestone include dimension stone for use in construction and in architecture, roofing granules applied as a weather and heat-resistant coating on asphalt-impregnated roofing, flux stone in smelting and other metal refining processes, as well as the production of Portland cement.

The largest use of lime is in steel manufacturing where lime is used as a flux to remove impurities such as phosphorus and sulfur. Lime is used in power plant smokestacks to remove sulfur from the emissions. Lime is also used in mining, paper and paper pulp production, water treatment and purification, and in wastewater treatment. It is used in road construction and traditional building construction.

Limult Magnesite Mining and Processing Factory in Nigeria

Magnesium is the lightest of all metals, being about two-thirds lighter than aluminum. Magnesium is non-toxic, non-magnetic, has high-impact strength and is resistant to denting. Magnesium is too reactive to occur in nature as an element, but its compounds are common. 

Magnesium is used in super-strong, lightweight materials and alloys. For example, when infused with silicon carbide nanoparticles, it has extremely high specific strength.

Magnesium is one of the most abundant element in the Earth's crust. Elemental magnesium is a gray-white lightweight metal and occurs naturally only in combination with other elements. The metal can be produced artificially, but is highly reactive.

When exposed to the atmosphere it is coated in a thin layer of oxide that partly inhibits reactivity. Magnesium is used in super-strong, lightweight materials and alloys.

The largest single use for magnesium metal is in aluminum alloying, accounting for about 50% of the total magnesium metal consumption. The addition of magnesium to aluminum produces high-strength, corrosion-resistant alloys.

About 20% is used in castings and wrought products including machinery, tools and other consumer products such as parts for cars. Magnesium is also useful in removing sulfur in the production of iron and steel, and the production of titanium in the Kroll process.

Limult Lead Mining and Processing Factory in Nigeria

Lead is a dense, soft, low-melting metal. It is an important component of batteries, and about 75% of the world's lead production is consumed by the battery industry. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays. Lead resists corrosion by water, so it has long been used in the plumbing industry. It is also added to paints, and it makes a long-lasting roofing material.

Lead is a health hazard to humans if it is inhaled or ingested, interfering with the production of red blood cells. Its use must be carefully controlled, and several formerly common uses of lead are now restricted by the government.

Lead paint is found in many older buildings, but it is now mostly used on outdoor steel structures such as bridges, to improve their weatherability. A lead compound called tetraethyl lead was added to gasoline as early as 1921 because it prevented the "knocking" problem of high-compression automobile engines. However, most gasoline now contains no lead, because lead from car exhaust was a major source of air pollution.

Lead is also commonly used in glass and enamel. In television picture tubes and computer video display terminals, lead helps block radiation, and the inner, though not the outer, portion of the common light bulb is made of leaded glass. Lead also increases the strength and brilliance of crystal glassware. Lead is used to make bearings and solder, and it is important in rubber production and oil refining.

Raw Materials

Lead is extracted from ores dug from under-ground mines. More than 60 minerals contain some form of lead, but only three are usually mined for lead production. The most common is called galena. The pure form of galena contains only lead and sulfur, but it is usually found with traces of other metals in it, including silver, copper, zinc, cadmium, and antimony as well as arsenic.

Two other minerals commercially mined for lead are cerussite and anglesite. Over 95% of all lead mined is derived from one of these three minerals. However, most deposits of these ores are not found alone but mixed with other minerals such as pyrite, marcasite, and zinc blende. Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver. Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteries.

LIMULT group provides whole Line Plant & Design Personnel Training, helping mine owners with Equipment Procurement and Construction from ore to pure gold.
