 THIS IS THE REASON WHY THE BANK LIKE GIVING US PROJECTS BECAUSE WE DO OUR JOB ACCORDING TO THE BOOK.


There may be variations as every project is unique and follows different design and construction process. In general, the basic steps involved in a building project are briefly explained.


Planning


Permits


Preparation of Construction Site


Foundation Construction


Superstructure Construction


Punch Lists


Building Warranty Period


1. Planning


The planning in building construction involves three major steps:


Developing the Building Plan


Analysing the Finance


Selecting the Construction Team


Once the site where the building project is indented to construct is chosen, the expertise of engineers and architects are taken to develop the site and the building plan. Sometimes, an appropriate site is selected after the building layout is prepared. The building plan is developed based on the owner’s requirements and budget.

Once the plan is in hand, the finance and total cost is estimated. The structural design details, the material estimates are prepared which help to derive project cost estimate. The cost calculated include:


The material cost


The construction cost


The labor cost


Miscellaneous cost


Based on the estimated cost, either a bidding process is performed or the project to handover to a known contractor. The contractor and the owner must agree to contract based on which the project is implemented. The contract mentions the completion period and necessary guides, exclusions to remove claims.


2. Permits and Insurance in Building Construction


Before starting a building construction, the owner must make sure that one has necessary permits taken to start the construction. Permits and insurance are obtained from different sources in cities and states.

A construction work conducted without permits results in project delay or project demolition or huge fines. Possessing insurance for the required parties helps to save the owner and the contractor.


3. Site Preparation


From here, the actual construction process starts. Based on the site and building plan, necessary excavations, leveling, and filling can be undergone to prepare the site. The necessary excavation for utilities, power, water and sanitation lines, temporary storage facilities are prepared. Mostly the works needed to set up the utilities are prepared. This is followed by an inspection from the government officials.

Inspections are performed at different stages on structural, building codes, the utilities, HVAC, electrical works etc. After the completion of the whole project, a final inspection is performed.


4. Foundation / Substructure Construction


Building structures are generally constructed on concrete foundations. Based on the soil type and water table level of the area, the foundation chosen can vary. If necessary, soil testing is performed to check the bearing capacity. Shallow foundations are required for low-rise building. For high-rise building, pile foundation is employed.

Once the foundation is selected, the soil is excavated to construct the foundation. It is performed based on the foundation layout. Formworks are placed in the foundation trenches and reinforcement is placed based on the foundation detailing design prepared in the planning stage. The reinforcement works performed by the contractor is periodically checked by the engineer in charge.

The concrete mix of the required proportion is poured to formwork and is cured to form the finished foundation.


5. Superstructure Construction


The superstructure is constructed once the substructure is complete. Generally, a framed structured is developed which is later finished with masonry walls. Adequate windows and exterior doors are placed based on the building plan. Other works coming under this section is:


Construction of roofs or siding


Installation of heating, ventilation and air conditioning


Providing adequate electric and water lines connection line.


Provide insulation works as required to protect from lighting


Provision of waterproofing to the walls.


Plastering and finishing the walls and surfaces


Flooring works


Exterior and Interior Painting


6. Punch List


Once the project is complete, the contractor inspects the whole work one by one and make a punch list. Those structural units or areas that were not constructed properly or are below the quality level is listed in the punch list. This is later corrected by the contractor in charge.


7. Warranty Period


Once the project is complete and handovered to the owner, the contractor specifies a warranty period. Within this period, any defects found in building constructed must be fixed and replaced by the contractor in charge. The warranty for materials and appliances are obtained from manufacturers and suppliers.

How do Mc Mushongo investment cc Effectively Manage Construction Supply Chain?

-

  Every player in the construction sector, in one way or the other, is a part of the overall supply chain. The project designer, materials supplier, subcontractors, the main contractor, and the client often act as the links of the supply chain across different construction projects and operations. Construction supply chains (CSC) are known to be complex, and their intricacies keep increasing with the growing magnitude of the project. The complexity further increases with the involvement of more people, i.e., first-tier, second-tier suppliers, and other tiers of sub-contractors, etc. The scope of the project is correlated to the complexity of the supply chain as more manpower, parties, and materials are needed for the completion of the project. Thus, it is essential to implement proper planning, organization, and collaboration between supply chain partners for a seamless supply chain operation and a smooth 1.  Development of Suppliers and Subcontractors Mc Mushongo  investment cc

Solar window

 What are Solar Windows? Solar windows are windows with solar panels that absorb ultraviolet and infrared light and convert them into electricity. They use the concept of building-integrated photovoltaics (BIPV).   What are the advantages of Solar Windows? • Solar windows reduce the indoor temperature during the summer season. • They reduce power consumption and hence utility bills. • They block ultraviolet radiation, preventing fading of interior furniture. •Solar windows increase privacy by providing a tinting option.  •They reduce glare within the building. •The cost of installation is low compared to solar panels. They lower carbon footprint. As per Ubiquitous Energy (a leading manufacturer of solar windows), solar windows are 30% more expensive than conventional windows. But this is compensated considering the yearly reduction in utility bills and the decrease in global emissions. https://liuphilipusmushongo.blogspot.com/?m=1

How do Mc Mushongo Investment cc Improve Masonry Resistance Against Penetration of Water?

-
Image
First of all We advice our architect  to select and design type of a wall that is suitable for the degree of forced rain severity anticipated in the location of the project. Completely grouted barrier wall or drainage wall with minimum thickness of 20 mm is recommended for seriously driven rain condition. Design of Drainage Wall to Improve Water Penetration Resistance of Masonry When drainage wall is selected, the wall should be designed in such a way that prevents the water penetration through the outer Wythe of the wall. For the outer Wythe masonry wall maintain its water resistance ability, cracks under service load should be prevented. When masonry cement is employed, the lower tensile bond strength of the cement should be considered in specifying whether the veneer will crack or not whereas if steel studs are utilized it is recommended to consider the steel flexibility in determining whether the veneer cracks or not. If the cavity wall is determined to be employed, the design
