Katika utayarishaji wa Bills of Quantities (BoQ) kuna column ya maelezo ya kazi, inafuatia column inayoelekeza kazi hiyo itafanywaje kama ilivyofafanuliwa kwa kina katika maelezo ya ubora wa kazi kwa mujibu wa mkataba huo "Specifications", kisha column ya kipimo cha kazi husika "Unit" halafu idadi yaani "Quantity" kisha "Rate" na Amount.

Amount = quantity x rate. Kwa maana hiyo kazi za matengenezo ya barabara ni nyingi na zinatumia unit mbalimbali kama km, m, mita za mraba, mita za ujazo, lita, uzito kama kg, tonne n.k. Kwa maana hiyo kila kazi inapimwa kulingana na unit yake. Kwa mfano kama BoQ inaonyesha kuchonga barabara "light/heavy grading" kilometa kadhaa, hizo inatakiwa barabara hiyo ichongwe kwa urefu huo. Kama ilikuwa kuweka changarawe mita za ujazo kadhaa = (Upana wa barabara x Kina cha changarawe zilizoshindiliwa x urefu wa kuwekwa changarawe) inatakiwa ifikiwe.

Mara nyingine huwa inatokea kazi kuchelewa kuanza kutokana na upatikanaji wa fedha hivyo kukuta kazi nyingine zimeongezeka na hivyo kufanyika kwa re scoping ya hadi 15% ya Contract sum kama msimamizi wa kazi kwa niaba ya mwenye kazi atakavyoamua 'but with due diligence' (angalia PPRA General Conditions Contract for small works clause 5 & 41). Kwa hiyo inahitakika uwe unaujua mkataba na usome mwenendo mzima wa utekelezaji wake.

Nadhani nitakuwa nimesaidia kuona muunganiko wa BoQ na kazi site inavyokuwa. kama una maswali mengine karibu wadau wa forum wako imara
