Using the Quantity Surveyor's record given in Appendix 'A', prepare an interim valuation for payment certificate No. 4.

Huu hapa ni ukokotozi wa tathmini ya muda kwa cheti cha malipo Na. 4: Step 1: Kokotoa thamani ya kazi iliyokamilika kwa kila shughuli. Hii inajumuisha kuzidisha "AMOUNT IN BQ" na asilimia iliyokamilika. Excavation: 580,200.00 × 0.93 = 539,586.00 Foundation, walling and oversite concrete: 230,400.00 × 0.72 = 165,888.00 Walling: 580,200.00 × 0.44 = 255,288.00 Openings: 130,600.00 × 0.25 = 32,650.00 Roofing: 720,000.00 × 0.51 = 367,200.00 Finishes: 920,550.00 × 0.12 = 110,466.00 Fillings: 380,900.00 × 0.09 = 34,281.00 Drainage: 1,893,420.00 × 0.35 = 662,697.00 Plumbing: 2,344,205.00 × 0.60 = 1,406,523.00 Electrical: 1,204,215.00 × 0.15 = 180,632.25 External works: 2,004,230.00 × 0.40 = 801,692.00 Preliminaries: 1,345,000.00 × 0.68 = 914,600.00 Step 2: Jumlisha thamani ya kazi zote zilizokamilika. Jumla ya Kazi Iliyokamilika = 539,586.00 + 165,888.00 + 255,288.00 + 32,650.00 + 367,200.00 + 110,466.00 + 34,281.00 + 662,697.00 + 1,406,523.00 + 180,632.25 + 801,692.00 + 914,600.00 = 5,471,503.25 Step 3: Jumlisha thamani ya vifaa vilivyopo mahali. Jumla ya Vifaa Vilivyopo Mahali = 25,000.00 + 28,000.00 + 32,000.00 + 48,000.00 + 28,000.00 + 110,000.00 + 52,000.00 + 24,000.00 + 45,000.00 + 15,000.00 = 407,000.00 Step 4: Kokotoa jumla ya tathmini halisi. Hii ni jumla ya kazi iliyokamilika na vifaa vilivyopo mahali. Jumla ya Tathmini Halisi = 5,471,503.25 + 407,000.00 = 5,878,503.25 Step 5: Jumlisha malipo yote ya awali. Jumla ya Malipo ya Awali = 1,421,428.00 + 346,213.50 + 1,543,003.25 = 3,310,644.75 Step 6: Kokotoa kiasi kinachostahili kwa Cheti cha Malipo Na. 4. Kiasi kinachostahili ni jumla ya tathmini halisi ukiondoa malipo ya awali. Kiasi Kinachostahili = 5,878,503.25 - 3,310,644.75 = 2,567,858.50 Kiasi kinachostahili kwa Cheti cha Malipo Na. 4 ni: Ksh 2,567,858.50 Tuma swali linalofuata 📸
