Project using Total Construction Service The project is to construct a new hotel on a virgin site.

Teams Team-days Brief 1 80 Design 10 460 Plan 1 50 Procurement 4 120 Manufacturing 8 150 Production 32 1340 Commissioning 4 100 TOTALS 60 2300
For a project with 60 teams (N=60) Possible relationships = 60 x 59/2 = 1770 1196 of these do not occur Actual relationships 1770 – 1196 = 574
Largest number of teams in one time interval is 20 in 13th time interval Technical design teams are producing production information for the last remaining components Half of the manufacturing teams are manufacturing fully designed components Substructure production is in full swing The work is supervised by the control teams 20 x 19/2 = 190 possible relationships
During the 13th time interval the following teams work simultaneously 2 out of 4 technical design teams 2 out of 2 production information teams 2 out of 2 plan and control teams 1 out of 1 contracts and payment system teams 4 out of 8 manufacturing teams 3 out of 3 substructure teams This gives a total of 14 teams with 91 relationships
Established Relationships Every team on a project has established relationships with at least one but often several other teams giving a total of 568 established relationships Established Relationships Indicator ER=568/574=0.99
The relationship fluctuation indicator FE = 0.99 This reflects a strong influence of established relationships throughout the project because both ER and FE are comparatively really high Total construction service companies are based on established relationships developed over many past projects
Relationship Quality Indicator for established relationships ranges from 0.95 to 0.99 Total Relationship Quality Indicator 560/574=0.98 The high number of established relationships together with the number of high values for individual Relationship Quality Indicators means the total Relationship Quality Indicator is good because the 568 established relationships out of possible 574 relationships are of very high quality
The project organisation is not overly complex There are 30 time intervals out of a potential maximum of 119 The intervals are relatively short in comparison to total project duration (prevent escalation of problems when teams interact for a prolonged period) Relationships configuration complexity indicator = 0.83
The past performance of the 60 teams over their previous 10 projects provides team Performance Variability Indicators which range from 0.95 to 1.0 Performance Variability Indicator Rp=0.99
Historical records for projects using Total Construction Service gives External Interference Indicator = 0.84
Project using Total Construction Service Established Relationships ER=0.99 Relationship Fluctuation FE=0.99 Relationship Quality QR=0.98 Relationship Configuration CR=0.83 Performance Variability Rp=0.99 External Interference I=0.84
