Estimating is a fundamental part of construction projects. Accurate cost estimate is the single most important element involved in the series of events that leads to a profitable completion of a contract in construction industry. The success or failure of a project depends on the accuracy of cost estimation. A cost estimate becomes more difficult and more complicated under inflationary medium. An unpredictable inflation rate and long progress payment delay during this period makes the budgeting function very difficult, if not impossible. The cost estimation process uses lots of data. The availability of the appropriate data at the appropriate time is one of the main factors affecting the accuracy of the cost estimation. As the complexity of the estimating task increases computerized system becomes increasingly important. The estimator should develop a good system of estimating forms and procedures that exactly meet the requirements of the pro- ject, and that is understood and accessible by all team members. This system should provide the ability to define material, labor hour and equipment hour quantities required for the project. Material, labor, and equipment unit costs are then applied to the bill of quantities. This paper presents An Integrated Web-Based Data Warehouse and Artificial Neural Net- works Model for Unit Price Analysis with Inflation Adjustment system called “DANUP“. Web facilities and database management capabilities of Microsoft Visual Studio 2005 are applied to create a data warehouse which is mainly aimed to integrate data from multiple heterogeneous databases and other information sources. The System also supports integrated cost index for adjusting the effect of inflation during estimating process. An artificial neural network model for forecast- ing the cost indices in Turkey for the project period has been developed. A construction project takes relatively long time to complete, effective communication among the project participants during the project period is important. A web based system is developed to facilitate the collection of construction cost information and communication. The web based sys- tem focuses on demonstrating the potential of data centric web data bases in enhancing the communication process during project execution. End users can access the database through the internet and perform certain transactions according to their authorization. Santrauka Sąmatos sudarymas – esminė statybos projektų dalis. Tiksli sąnaudų sąmata – vienas svarbiausių elementų, susijusių su įvykiais, kurie statybų sektoriuje leidžia pelningai įvykdyti sutartį. Projekto sėkmė arba žlugimas priklauso nuo to, ar tiksliai įvertintos sąnaudos. Infliacinėje aplinkoje sąnaudas įvertinti sunkiau ir sudėtingiau. Dėl neprognozuojamo infliacijos lygio ir ilgalaikių dalinių mokejimų vėlavimo per tokį laikotarpį biudžetą numatyti itin sunku, o gal net neįmanoma. Vertinant sąnaudas reikia gausybės duomenų. Galimybė reikiamu metu gauti reikiamus duomenis – vienas pagrindinių veiksnių, darančių įtaką sąnaudų sąmatos tikslumui. Kadangi sąmatas sudaryti vis sudėtingiau, vis svarbiau yra naudoti kompiuterizuotas sistemas. Sąmatininkas turi suformuoti gerą sąmatų sudarymo formų ir procedūrų sistemą, tiksliai atitinkančią projekto reikalavimus, suprantamą ir prieinamą visiems komandos nariams. Tokioje sistemoje reikia funkcijos, leidžiančios nurodyti projektui reikalingų medžiagų, darbo valandų ir įrangos naudojimo valandų skaičius. Tuomet medžiagų, darbo ir įrangos vienetų kainos įtraukiamos i sąmatą. Šiame darbe pristatoma integruoto internetinio duomenų saugyklos ir dirbtinių neuroninių tinklų modelio, tinkamo analizuoti vieneto kainą, atsižvelgiant į infliacija, sistema, pavadinta ”DANUP“. Naudojant Microsoft Visual Studio 2005 internetines ir duomenų bazių valdymo funkcijas, sukuriama duomenų saugykla, kurios svarbiausias tikslas – integruoti iš daugybės heterogeninių duomenų bazių ir kitų informacijos šaltinių gautus duomenis. Be to, naudojant sistemą galima sudaryti integruotą sąnaudų indeksą, kuris sudarant sąmatą leidžia įvertinti infliacijos poveikį. Buvo sukurtas dirbtinio neuroninio tinklo modelis, leidžiantis Turkijoje prognozuoti sąnaudų indeksus, kurie galios vykstant projektui. Statybos projektas trunka gana ilgai, taigi vykdant projektą svarbu, kad bendravimas tarp jo dalyvių būtų efektyvus. Buvo sukurta internetinė sistema, padedanti rinkti informaciją apie statybų sąnaudas ir bendrauti tarpusavyje. Pagrindinis internetinės sistemos tikslas – parodyti, kaip, remiantis duomenų kiekiu grindžiamomis internetinėmis duomenų bazėmis, vykdant projektą galima pagerinti komunikaciją. Galutiniai vartotojai duomenų bazę gali pasiekti internetu ir, priklausomai nuo prieigos lygio, atlikti tam tikras operacijas.

Like the project in general, slab work on Project Indonesia 1 uses one material, namely metal deck. The upper structure slab consists of 64 floors with a majority of 90% using a metal deck system. Where these components require support that can carry the workload, rebar, and fresh concrete. Starting with Metaldeck's non-reusable / fixed supporting (angle & anchor) design which is quite difficult to apply in the field, it has an impact on increasing time and increasing the cost of work. So the engineering team has the innovation of replacing non-reusable / fixed supporting material (angle & anchor) with reusable material (angle & drop hollow). Cost analysis is sought by calculating the RAB (Cost Budget Plan) using the unit price analysis used by the DKI Jakarta Government and how efficient the time gained. Based on the results of calculations and interviews with relevant experts on the project, the implementation of temporary supporting work costs was carried out using a non-reusable method of Rp.3,211,000,000.00. As for the implementation of the reusable method of Rp.649,916,800. There is a difference in cost between the non-reusable and reusable methods of Rp. 2,561,083,200.00. Where to implement the temporary supporting reusable method is cheaper than using the non-reusable initial method. Then in terms of installation time, the temporary supporting using the non-reusable method was 520 days while for the reusable method it was 260 days. There is a difference between the non-reusable and 260-day reusable methods. The results obtained that the use of Welded Angle & Drop Hollow as Temporary Supporting is more effective and efficient than using the initial Non-reusable method.

Project is any work that has a beginning and ending, consisting of several jobs/activities that must be carried out in a certain order. Contractors typically use the Gantt Chart Method in scheduling home construction projects so that it is difficult to know the impact caused by the late completion of work on scheduling the entire project. The purpose of this study is to determine the time needed to complete two housing units using the Precedence Diagram Method and the Line of Balance Method. The data used in this research are the dependency relationship between activities, time schedule, cost analysis plan (RAB), and SNI unit price analysis. The analysis process carried out in this study is to calculate the time needed to complete two housing units using two methods, namely the Precedence Diagram Method and the Line of Balance method. The results of this study indicate the time needed to build two housing units using the Precedence Diagram Method 7 days faster than using the Line of Balance Method.
