**construction methods & materials**Methods of Building Construction & measurements Prepared By Nedal AlShiekh 120060049 Aref AlGhool 120060639 Saeid AlSahar 120060641 Supervised By Dr.Wae'l Elbowab**Method of measurements**• 1- Conventional measurement (الكيل البلدي) • Depends on experience, and type of project. • Doesn't govern by theories or engineering basics. • Not considered as scientific method. (difference from place to another ) • Doesn't subtract the opening as windows or doors from the block, plastering, painting works and computing whole wall. 2- Engineering measurement (الكيل الهندسي) It is calculating all the works finished after subtracting all opening.**Building Construction Excavation & Fill Works**First choice the suitable equipments .**Building Construction Excavation & Fill Works**cont. For you as a site engineer The best way for excavation & fill works is by lump-sum. You can work by day /hour if you need. You can work by numbers of pits if you need. You can use any way according to the situation you have**Building Construction Excavation & Fill Works**The best way for excavation & fill works is by lump-sum.**Building Construction Excavation & Fill Works**You can work by day /hour if you need.**Building Construction Excavation & Fill Works**You can work by numbers of pits if you need.**Building Construction Excavation & Fill Works**You can work by day /hour if you need.**Building Construction Excavation & Fill Works**prepare the site for axis work & foundation**Building Construction Concrete works**The binding concrete for footing and Concrete for footing had the same way at measurement m³. At the Conventional measurement we had: • Concrete for column neck every two column necks ( with h ≤1.5 m) consider as 1 m³. • Concrete for column every column ( with h ≤ 3 m) consider as 1 m³. • Concrete for Ground beams every 5 M.R. consider as 1 m³. • Concrete for lintels every 6 M.R. consider as 1 m³.(some times make difference between external and internal lintels)**Building Construction Concrete works**cont. • Concrete for Floors and slabs measured by m² with out subtract the opening if found. • Concrete for stairs every 3 stairs consider as 1 m³ & every landing consider as 1 m³. • Foam concrete for final roof measured by m² with out subtract the opening if founded. • Concrete for decorations measured by NO.**Building Construction Concrete works**Start concrete works ,first binding concrete**Building Construction Concrete works**cont. concreteworks , binding concrete m³**Building Construction Concrete works**cont. concrete works , foundation concrete m³**Building Construction Concrete works**cont. concrete works , ground beams ,every 5MR = m³**Building Construction Concrete works**cont. concrete works , columns concrete every column m³**Building Construction Concrete works**cont.

Steel works , MPE (mechanical, plumbing and electrical)**Building Construction Concrete works**cont. Concrete for Floors and slabs measured by m² with out subtract the opening if found.**Building Construction Concrete works**cont. Concrete mixtures • Ready mixtures from concrete factories as you need. • Site mixtures at the work site as you need . for example we can make concrete B250 at the site by using the ratio 1:2:3 (1 cement: 2 sand : 3 aggregates) and water as needed and by experience. • 1m³ B250 needs 7 bags cement( 350 kg) . • The truck of sand or aggregates can be (20-25 ton)**Building Construction Concrete works**cont.

Aggregate by weight Sand by truck**Building Construction Concrete works**cont. Tractors 3-6 ton loader 1.50 ton**Building Construction Concrete works**cont. Concrete tests**Building Construction Concrete works**cont. Foam concrete • Foam concrete use for the final roof slopes. • Ready mixtures every 1m³ content of 400 kg cement :1100 kg sand :12 kg foam plus 2 liter admixtures. • The mixer carry from the factory 4 m³ and reach the site with 8 m³ (the foam extended).**Building Construction Concrete works**cont. Foam pump**Building Construction block works**• The engineering measurement of block works is by m². • The conventional measurement of block works is by m² with out subtract the opening and the lintels. • Every 1 m² is 12.5 block ( 20* 40* W). • The morter for block works 4:12 :2 ( cement : sand : Sheed). • Every 100 blocks need a morter of 1 bag of cement .**Building Construction Plastering works**• The engineering measurement of plastering works is by m². • The conventional measurement of plastering works is by m² with out subtract the opening. every angle measured as 1 m² , every 4-5 MR wire mish (يوتا أو خيش) measured as 1 m². • The morter ready mixture m³(1800kg sand :400kg fine aggregate .(ترابية) • The morter site mixture for plastering works: - القصارة البلدية4:10 :1 ( cement : sand : Sheed). - القصارة الشلخته4:16 :2 ( cement : sand : Sheed). دلو رمل بحر)2.5 +دلو شيد مصول 1) وجه الشلخته**Building Construction Plastering works**cont. • Room 4*4 m needsmorter mixture as : القصارة البلدية- 5 -7 bags of cement . القصارة الشلخته- 4 -5 bags of cement (for black plaster) و هذه الغرفة تحتاج 2 دلو شيد مصول • At the external plastering some times make a face called وجه باطون ) ) 4 : 6 (4 cement :6 sand) Mixture of 1 bag cement cover 12-15 m². • Tirylyon works الرشقة الخارجية (1كيس اسمنت أبيض: كيس4 كوارس :6 دلو رمل ) خلطة كيس اسمنت تغطي من 20- 25م² وجهين .**Building Construction Plastering works**cont. • Room 4*4 m needsmorter mixture as : القصارة البلدية - 5 -7 bags of cement . القصارة الشلخته -4 -5 bags of cement (for black plaster) و هذه الغرفة تحتاج 2 دلو شيد مصول • At the external plastering some times make a face called وجه باطون ) ) 4 : 6 (4 cement :6 sand) Mixture of 1 bag cement cover 12-15 m². • External works الرشقة الخارجية (1كيس اسمنت أبيض: 4 كيس كوارس : 6 دلو رمل ) خلطة كيس اسمنت أبيض تغطي من 20- 25م² وجهين .**Building Construction Tiles works**• The engineering measurement of tiles works is by m². • The conventional measurement of tiles works is by m² with out subtract the opening . - ² = 1م البانيل يكيل كل 2-3 م .ط - Windows sit measured by numbers. - Stairs marble measured by stairs. • The morter for ground tiles works 4:14:2 ( cement : sand : Sheed) cover 10 m². • The morter for wall tiles works 4:10:2 ( cement : sand : Sheed) cover 8 m².
