QSFemi:
Happy new year.

I pray 2021 will be a great year for us all.


Now, I want to address the question or concern of this person.


I'm a practising Quantity Surveyor, as such I've the obligation to respond to issues like this.

First of all, Quantity Surveyors arrive at estimated construction costs based on available documents - drawings, specifications and approved instructions.

What I've observed in my years of experience that could cause significant difference between a QS estimate and the actual cost of construction is mostly "difference in specifications between the construction (QS) specifications as stated in the Bill of Quantities and the actual specifications done on site".

I want to cite an example. A QS can describe in his BOQ that oversite concrete (german floor) to be 150mm (6-inch) thickness. During construction, many project supervisors will never do 150mm thickness on site. Most would rather do 75mm to 100mm. This will significantly reduce the estimated cost thereby making clients to think that QS estimate are over bloated. This is just one example out of many decisions that happen during construction.

How do will solve this problem?

Answer: Engage your QS beyond pre-construction duties. Engage the QS during the construction of the project for he can easily identify this gap and fill it swiftly.

Conclusively, QS do not "over-egg" bills like that person thought.

Have a blissful year ahead.

Where’s your location?

Good day everyone. I want to clear something up. Every businessman have his or her own principle and terms of working. If you ask for my opinion on the cost of doing a job and the materials you think will be enough, I can help you with that but asking me to review a quotation of another welder is something I will NEVER do. I don't know what he intends to do and how he intends to achieve it.

Some quotation maybe over bloated not because the welder or artisan intends to rip off the client but because costing the materials it will take to complete a job is something many can't do. That's why [b]quantity surveyors help engineers. [/b]Y'all will agree with me that most artisans are barely literate to communicate in english and we're talking about mathematics here. Sometimes it's innocent mistake and other times greed. Either way, it's not my duty to point out which for anyone.

You have to factor also that the cost of materials and living differ from place to place. A single door I can make with #20,000 costs above #35,000 in Lagos.

Having said the above, I regret any inconveniency it causes this forum and its established guidelines. Enjoy the new year

QSFemi:
I frown at the bolded. Quantity Surveyors do not "help" engineer because they weren't trained for them. Rather, the practice of Quantity Surveying is established by CAP NO 31 in 1986 by the act of the National Assembly.

Quantity Surveying practice is an independent field of practice in any country it's practised.

Quantity Surveyors are on the side of the project. Of course, engineers can patronise the services offered.

Thank you

I may just insist on him getting very good galvanized pipes. I'm just so much concerned about getting an alternative stand made with some different materials.

Below is the quote the technician gave me if he's gonna use 'U beam'. How good is the quote please?

Remember to tell everyone going for this to think of the maintenance cost o

It's not cheap to maintain at all!

Thanks Boss for your response

As requested, see my feedback

1. The hight is est. 3 Step block and that's the Entrance were the spoiler chair is... From the chair to the right hand side

2. It's going to be residential but no plan for kickoff now.... Still gathering capital to begin the process

QSFemi:
In order to have an objective answer, I'll advice you include the dimensions (length and breadth) of the building and the height of your Kingpost.

Beframia:
Good day and Happy New year everyone!
I want our experienced Pros in the house to kindly assist with: best wood type, sizes and quantities for a 4 bedroom flat with the attached footprint.
Proposed kingpost height is 4m (13ft) and parapet (concrete eaves) length is 1ft.
Thanks.

Amastermovic:
Good morning All,
I need to give some observation, read carefully.
As a silent reader I notice the trend of everyone wanting a steel tank stand, and materials suggestion keeps going on kindly notice the following.

Steel section are choose from expected load (tank size) ..but the bracing are always strategically place to reduce section at times or for stiffness purpose

If a steel section works in Lagos for example doesn't mean same will work in Abuja the wind pressure in each state in Nigeria is significantly different according to the wind isopleth data, so when assume this is always dangerous..

Section like UC, UB Angle iron etc all have minor axis and major axis meaning the direction of face are of important, reason you see people using CHS (recommended sizes) u don't have to worry about any local bending its strong all through .

The base plate need to be check like wise the HDB(hold down bolt)

The foundation this is important and done with three things put into consideration (weight of the steel ,wght of water , wind reactions on the structure ,live load of access also)

Not to bore you much your tank may be over designed (waste of money at least safe sha) or under designed (total waste of money and intending disaster waiting to happen)

A tank stand is a structural elements you should never toy with it because its failure is always a serious issues.

bixton:


Because your building plans is still in the future I'll advice you just fill the land with the sand to your desired level. It's called land reclamation. Ensure the demolished building+road excavated sand has more of the excavated sand so that it can settle by itself over time. If you can bargain less for the sand it will be nice and hope it's a 10 tyre tipper that will be heaped to the top.

Road excavated sands are good and most economical for such purpose especially when they are closer to your site at a give-away price.

Hmmm!

As I was reading this post, the project below came to mind. Steel structures are designed to specifications and not “as the spirit led.”
I believe someone would be telling the design team “If all the trusses connect at a point... blah, blah...”

I stick with my steel fabricator because he always ask for the engineering drawing for every small structures we are building.

He’s on the team of the guys that built Obasanjo Tank Farm. Just in case anyone need references

Hello,

Pls I would like to ask what is the average block (9" that can do for a foundation of 3 bedroom flat?

The description of the building are below....

1 master bedroom ensuite.....
I bedroom ensuite...
I bedroom ( plain room)
1 kitchen and store
1 parlour and dining.
1 ante room
1 public toilet...

I am at croosroad, because the man is calling 1000 blocks of 9" for me and I presumed it shouldn't be more than that....
PS..the building will be structured on half plot of land..

Regards

Jasobry:


Do you mean to write 1000 or 10,000?

spyder880:
Let's do this again, which do you prefer, and why?

The high roof, or the contemporary style?

kobocity:
There's no need to ask again! Don't get cheated again!!

Idumota is a name that always give me some feeling. It was the place I shell out #25000 to buy Sonny TV and VCR when a plot of land was going for #12000 in Abijo. Every time I am in Lagos island the memory always hunt me. The foolishness of my youth. I could have bought NEC or Goldstar(LG) for half the price and be watching that plot(with a 4 room face me face you) appreciating today

Carmal90:


1000 as foundation sir..
Is he on right track?
