  2. 2. ARCHITECTURE&CONSTRUCTION AGENCY The Architecture&Construction Agency (ACA) has been founded as a private company in 1993 with a separate department for design of steel and reinforced concrete structures. During the last years ACA took active part in the technological modernization of the cement industry in Bulgaria. Various customers and investors have chosen ACA to design industrial and civil structures including unique industrial facilities. The Agency is renowned for its quality design, strict dead lines keeping and flexibility when design modifications do need to occur. The design process is entirely computerized and uses up-to-date technology. ACA design team has an expert level in using specialized software such as ArchiCAD for architectural drawings, AutoCad for detailed and workshop drawings, SAP2000 for static, dynamic and earthquake analysis of structures. When contracted ACA performs full engineering of industrial facilities.

(ACA) has been chosen by ItalCementi Group toperform full engineering services on the Coal Mill Project in the Vulkan Cement Plant,Dimitrovgrad, Bulgaria. The total of 9 months design and construction duration time for theproject began in March 2000 and finished in December 2000 with installation start-up. The newCoal Mill Facility is now used to supply Kilns 3&4 with grounded mixture of coal and cokeinstead of the expensive natural gas.ACA in cooperation with TAI (Italian engineering company that supplied basic design for theproject) and CTG (Engineering Department of ItalCementi Group that approved all drawingsduring design) prepared and supplied the following documentation:− civil works foundations (engineering calculations, reports and detailed drawings)− steel supporting structures (engineering calculations, reports and detailed drawings)− ducts, chutes, compensators (engineering calculations, reports and detailed drawings)− coal dust silo (engineering calculations, reports and detailed drawings)− steel structure covering the coal mill, cladding with corrugated steel sheets, stairways, galleries for belt conveyors, service platforms, etc. (engineering calculations, reports and detailed drawings)− steel doors (detailed drawings)− authorization of the electrical installation documentation (project drawings and reports supplied by and in cooperation with the Italian Company Seit)For this particular project ACA engineering team used software packages such as ArchiCad forarchitectural drawings, AutoCad 2000 for detailed and workshop drawings, MATHCAD forcalculation reports, SAP 2000 for modeling and static, dynamic and earthquake engineeringcalculations based on FEM, etc. The final documentation was supplied by ACA as a hard copyand computer files.

  5. 5. ACA team of young and highly qualified Civil and Structural Engineers (all university graduates)managed to supply in short terms an excellent Job on a unique for the Bulgarian Industry coal mminstalfation. During the design development of the project substantial restrictions appeared due tothe fact that some new equipment had to be placed inside an old existing building increasingheavily the job complexity. During the whole contract and duration of the project ACA engineersprovided reiable services in the field of the Industrial Civil and Structural engineering as well asWorkshop Detailing. All ItalCementi project requirements and deadlines were kept within narrowlimits ACA engineering department took full advantage of the modem IT and computerSology thus being able to send, receive and process massive number of computer drawingsper day. ACA easily achieved a high quality end product, which was initial compulsoryrequirement by ItalCementi for granting the full engineering service contract. Personally wasvery impressed by the professionalism of ACA engineers in their everyday contact with theirCTG, TAI and Seit colleagues. The result was cost effective coordination and quick approval ofdrawings.I do consider ACA engineering team as very experienced and professional in the area of industrialconstruction and modernization and have the pleasure to sign this recommendation addressing itto any Bulgarian or foreign investor. Sincerely Yours,P. Grancharov, M.Sc.Modernization and Reconstruction Project Manager

(ACA) received its first contract with DevnyaCement in 1997 to perform engineering and structural services on the project Coal MillFacility for Kilns 5&6. This facility in operation since 1999 supplies Kilns 5&6 withgrounded mixture of coal and coke instead of the expensive natural gas.ACA in cooperation with Loesche GmbH (German manufacturer and supplier of thecoal mill unit) prepared and supplied the following documentation:− civil works foundations (engineering calculations, reports and detailed drawings)− steel supporting structures (engineering calculations, reports and detailed drawings)− ducts, chutes, compensators (engineering calculations, reports and detailed drawings)The next contracts awarded by Devnya Cement to ACA in cooperation with ChristianPfeiffer (Austrian manufacturer and supplier of grinding equipment) were forengineering services for the reconstruction of Cement Mills 3&2&1 with modificationfrom open to closed technological cycle (filters, separators and related equipment).Cement Mill 3 project ended in 1998, Cement Mill 2 project ended in 1999 and CementMill 1 project is planned for year 2002. ACA supplied workshop drawings for allrelevant steel supporting structures and service platforms.In 2000 Christian Pfeiffer (supplier of the new equipment for Cement Mills 3&2&1)together with ItalCementi Group contracted ACA to perform an earthquake analysis ofthe existing cement mill building and to estimate the influence of the new structures andloads on the building. A detailed model of the building was created. The earthquakeanalysis proved that certain structural elements of the existing cement mill buildingneeded modification and reinforcement due to new substantially greater dead and serviceloads. ACA engineering department prepared detailed drawings for the reinforcement.The project was finished at the end of 2000.For the contracts mentioned above ACA engineering team used software packages suchas ArchiCad for architectural drawings, AutoCad 2000 for detailed and workshopdrawings, MATHCAD for calculation reports, SAP 2000 for modeling and static,dynamic and earthquake engineering calculations based on FEM, etc. The finaldocumentation was supplied by ACA as a hard copy and computer files.

  7. 7. ACA team of young and highly qualified engineers (all university graduates) provedtheir ability to offer in short terms high quality engineering solutions to the complexdemands for modernization and reconstruction in the Bulgarian cement industry in thelate 90s. During the design development of the projects supervised by me allrequirements and deadlines were kept within narrow limits.The high quality end product that ACA persistently achieved would be a great advantageto any organization especially if cost effective coordination and quick approval ofdrawings is needed.I do consider ACA engineering team as very experienced and professional in the area ofindustrial construction and modernization and have the pleasure to sign thisrecommendation addressing it to any Bulgarian or foreign investor.Sincerely Yours,P.

  8. 8. Christian Pfeiffer Systems and components REFERENCE Christian Pfeiffer started to work with Architecture&ConstructionAgency in 1998 on the cement mill No. 3 modernization project locatedat the Devnya Cement Plant, Varna, Bulgaria. The deadline for theproject was 6 months, a very short time for such reconstruction. The jobconsisted of partial modification of the main structure of the cement millbuilding and an addition of a new structure for our equipment. Based onour technological flowsheet and preliminary drawings ACA engineeringteam in short time managed to produce quality workshop and detaileddocumentation for fabrication and erection purposes. After the initial successful business relationship in 1998 during thenext two years Christian Pfeiffer and ACA managed to modernize andreconstruct also Cement Mill No. 2 and part of Cement Mill No. 1. Due to new and substantially greater dead and service loads onthe cement mill building an earthquake survey and structuralmodification for strengthening of the existing building was necessary.ACA received an order and its team accomplished the job in less thanthree months. The final documentation consisted of a very detailedearthquake analysis and workshop drawings for steel structuremodifications. It was a pleasure for us to work with ACA young and ambitiousengineering team during the past three years. I would also recommendACA as a reliable partner for engineering services to any eventual investor inthe Bulgarian Industry or abroad.
