STORY OF RICHARD DZIEWOLSKI AND CCERET ENGINEERING

RICHARD DZIEWOLSKI

After working as an engineer in metal construction in various companies (especially CFEM = EIFFAGE) and a research centre (CTICM), he set up his own engineering firm - board member of CICF, AIPC, AFPC, his company CCERET ENGINEERING and his ARCHITECT'S office near Paris (Boulogne 92100 (see detailed bio, publications and patents*). Since setting up his company, the office on the French Riviera and "START UP" RC Cannes he has been following the activities of his firms and companies, and he devotes most of his time to research and development for his most recent project "MARINARIUM 03 floating island, self-sufficient in energy and respecting the environment"
DETAILED BIO OF RICHARD DZIEWOLSKI
Richard Dziewolski was born in Poznan (Poland) on 2nd April 1935 to father Stanislaw Dziewolski engineer-architect and mother Irena Kotowicz professor of natural sciences (see Facebook family)

1958: Engineering diploma at Warsaw Polytechnic
1958: Emigrated to France.
1958: Work experience – designer at a metal construction company (ERNEST PANTZ  PARIS  at PIERREFITTE), engineer calculator at Société d'Études et de Distribution de Matériel Industriel in PARIS (while pursuing French studies at Alliance Française)
1959 to 1964: Engineer at Compagnie Française d'Entreprises (CFE =CFEM= EIFFEL=EIFFAGE), as research officer (calculations and plan guides) for bâtiment de Laminoir du Complexe Sidérurgique de Dunkerque and for a dozen metal bridges.
The building structure studies posed various theoretical problems; notably torsion in beams of box structure bearings and flexion in knuckles of gantries in box structures (little-known problems at the time of manual calculations).
These problems drove Richard Dziewolski to pursue his studies at the Faculty of Sciences at the University of Paris in parallel with his work
1963: Engineering thesis - Doctorate (First Class Honours) on the problem of calculation of structures: "non-uniform torsion in beams with narrow walls and a profile composed of closed and open elements"
From 1963 to 1965: engineer at Centre Technique Industriel de la Construction Métallique (CTICM) tasked with research in the area of non-uniform torsion and calculation of structures by computer (secretary of working group "electronic calculation")
A communication from Richard Dziewolski "theoretical and experimental study on an asymmetrical box beam with two appendages" was chosen by the science jury  to be published and presented at the 7th congress of the Association Internationale des Ponts et Charpentes in Rio de Janerio in 1964. It was referred to in the speech by Prof. STUSSI AIPC President.
The theory of calculation for beams under non-uniform torsion developed by R. Dziewolski during his thesis (see bibliography) facilitated devising a new method for calculation of the coefficient of transversal load distribution used in calculations for bridges, thus improving on the Courbon method and in the simplified calculation of  non-uniform torsion beams;  
(see publications in technical journals).
1965:  creation  of  engineering-consultation office: "Centre de Calculation Électronique, de Recherches et d'Études Techniques " (CCERET ENGINEERING)  
in  BOULOGNE 92100
1966: development of an electronic structural calculation program STROP (STRuctures - OPtimisation), one of the first structural calculation programs developed in France and covered by a number of publications.
This program facilitated calculation and optimisation of the weight of complex structures, especially three-dimensional structures of steel tubes, where calculations were particularly complex and difficult to approach with traditional means at the time.
1967: Grant of French nationality (decree dated 27/04/1967.)

Richard Dziewolski worked together with:
Stephane du Chateau engineer-consultant specialising in three-dimensional structures, for whom he produced calculations for several structures
Prof. MAKOWSKI at UNIVERSITY OF SURREY specialist in spatial structures and author of several scientific works
ASCE "Planning and Design of Tall Buildings" Lehigh University USA
Chambre Syndicate des Fabricants  des Tubes d'Acier et Cometube

Extract from achievements as engineer/consultant in metal framework
HAVAS CONSEIL A NEUILLY building (architects: Andrault et Parat) which won the competition prize for the most beautiful work in metal framework in France in 1974 (category: buildings with non-industrial design) awarded by Syndicat de
Salle Omnisport de Nantes (architects: Evano and Pellerin) three-dimensional, three-directional structures in hexagonal shape with 80mm range and spherical nodes
This project was awarded a prize in 1979 by the jury of an international competition organised by Convention Européenne de la Construction Métallique pour les constructions remarquables en acier (see ref.)
Three-dimensional composite steel structure - concrete with spherical welded nodes (stability in fire: 1 hour)  covering congress hall in MONACO and bearing a heavy weight (accessible terrace)
Study of an aluminium dome with mesh layer and outgrowth beams, selected by the science jury of Association Internationale des Ponts et Charpentes for presentation at the 9th AMSTERDAM CONGRESS IN 1972
It is the second time that Mr. Dziewolski with 6 other engineers represented France at the AIPC congress ("olympic games" for engineers and scientists)
Studies of various tubular structure projects facilitated development of several construction processes  (see list  on website).
The following should be mentioned:
Procedures SS1 and SS2 (spatial structures; several completed)
Pylons supporting high-voltage electric lines in pyramid shape with triangular base and tubular construction (patents, participation in international tenders in Costa Rica, Guatemala, Panama, prototype trials by EDF)
The construction process developed facilitated savings of 35 % to 45% in the weight of pylons and reduction in the assembly cost placing the CCERET team.
    
TEACHING ACTIVITIES:
 1970,1974, 1975:  École Nationale Supérieure des Beaux Arts in Paris
Conferences: Spatial structures with Mr. du Château
1974, 1975: Ecole Nationale Supérieure des Ponts et Chaussés in Paris

On the one hand with a passion for architectural creation, and upholding the family vocation on the other (grandfather bridge and road engineer and father architect) in parallel with engineering – consultant activities and managing CCERET INGENEERING Richard Dziewolski pursued his architecture studies at École Nationale Supérieure des Beaux - Arts in Paris (Atelier Gillet).
1970: DPLG architect diploma 
1970-1971: creation of architecture firm enabling him to complete his tasks in the areas of engineering and architecture.
Richard Dziewolski the architect won several engineering and architecture competitions and completed various buildings and constructions (office buildings,  information centres, workshops and shops, garages, restaurants, dwellings, individual houses, aeroplane hangars, swimming pools, skating rinks, sports complexes, towers  etc.)  on behalf of large organisations, administrations and companies (EDF, GDF, FRANCE - TELECOM, AEROPORT DE PARIS, private promoters, OPAC, municipalities, etc.)

Given the extent of expenditure incurred by the team participating in competitions (whose results were often dubious) R. Dziewolski decided to develop the service "assembly of operations"  and  "turnkey construction".
1991 - 1994 the company CCERET ENGINEERING  was part of the group ARCHITECTEURS  (completion of buildings with guaranteed price and timing)
 
Since 1967 the Richard Dziewolski study office CCERET ENGINEERING also worked in the area of offshore construction by participating in studies of offshore platforms, derricks, cranes and towers on behalf of various companies:  FOREX , ELF, TOTAL , CFEM, UIE, FROG, MACDERMOTT, BROWN AND ROOT, etc. (see CCERET ENGINEERING  offshore page). In parallel he did research on new deep-water offshore platforms (several patents registered and projects developed).

Since 1982 Richard Dziewolski has been pursuing research in the area of offshore leisure complexes. Notably he developed the projects MARINARIUM (1,2, and 3) consisting of high-tech tourism products, respecting the norms of sustainable development with high profitablity and with multiple economic and social benefits.
The feasibilty studies completed over more than 20 years demonstrate the technical and economic feasibility of these projects.
