Timeline and building units for Gaillon-sur-Montcient, Notre-Dame-de-l'Assomption A 'building unit' is an arbitrary unit of work based on bulk billing techniques used by quantity surveyors. The unit is small enough to provide realistic figures in the small churches without becoming too huge in the large. Six units would pay for one small vaulted bay in an aisle about 3 metres square, or a small first-floor gallery. Such a bay would consist of an external wall with a small window, half of two columns about 3 meters tall, the floor and footings under them and the vault and roof overhead.

Phases for Gaillon-sur-Montcient, Notre-Dame-de-l'Assomption The building sequence is based on my on-site analysis of the construction history, using the techniques developed on the cathedral of Chartres called toichology, and described in a number of publications. The analysis of some of the smaller churches are more approximate than I would like, and need further analysis. <p>I have used 'phase' rather than 'campaign' to to identify a contiguous zone with similar elements. A campaign would be defined by recognisable breaks and construction joints in the fabric: there may be a number of phases within a campaign. One benefit is that separate programs by subcontractors, such as carvers, may be isolated, which is particularly useful in complex sections, such as portals. <p>Every phase has been assigned to a decade, so there may be more than one phase in a decade. <p>While this is certainly imperfect, it will allow us to explore all the data, including costs, across time. This is an on-going process, so as the data continues to be analyzed, the chronology and costing analysis will be further refined, and the synopsis updated. <p>Clicking on any of the decade graphics will display all buildings that had work being done during that decade.

The building sequence is based on my on-site analysis of the construction history, using the techniques developed on the cathedral of Chartres called toichology, and described in a number of publications. The analysis of some of the smaller churches are more approximate than I would like, and need further analysis.

I have used 'phase' rather than 'campaign' to to identify a contiguous zone with similar elements. A campaign would be defined by recognisable breaks and construction joints in the fabric: there may be a number of phases within a campaign. One benefit is that separate programs by subcontractors, such as carvers, may be isolated, which is particularly useful in complex sections, such as portals.

Every phase has been assigned to a decade, so there may be more than one phase in a decade.

While this is certainly imperfect, it will allow us to explore all the data, including costs, across time. This is an on-going process, so as the data continues to be analyzed, the chronology and costing analysis will be further refined, and the synopsis updated.

Earlier

Phase 1 - Earlier


Presumably there had been an earlier square bay and apse to the east, the buttresses on the east side of the crossing suggest a narrow bay; probably had transepts against which the later transepts were added.
1110

Phase 2 - 1110 - nave, crossing - 50 Units


Set out nave and crossing together with bases at the same height from setback in north side of WN buttress; bases of W-s door.
1110

Phase 3 - 1110 [1113] - crossing (c) - 30 Units


Crossing capitals with arches and buttresses to support the tower
1110

Phase 4 - 1110 [1116] - nave (a) - 20 Units


Nave capitals and imposts set against crossing
1110

Phase 5 - 1110 - tower I - 20 Units


Tower I, and buttresses changes 3 courses above arches into roof.
1120

Phase 6 - 1120 - tower II - 12 Units


Tower II from above previous change to openings in next level visible above choir vaults, round arches.
1140

Phase 7 - 1140 - north - 22 Units


North transept with triple shafts on three corners.
1160

Phase 8 - 1160 - W-s - 5 Units


South nave doorway shafts and caps added with a projecting gable roof.
1160

Phase 9 - 1160 [1159] - spire - 35 Units


Spire financed by Count Galeran
1180

Phase 10 - 1180 - south - 25 Units


South transept with en delit shafts against crossing; because the lower courses of stonework around the choir are very different to the upper, the external walls of the choir with buttresses were built at this time.
1210

Phase 11 - 1210 [1218] - choir (a) - 80 Units


Upper aisle walls of choir; the entire building erected independently of earlier with wider spans; choir piers and arcade arches, and aisle vaults and intended to demolish older west as new arcade arch started in EN1+aisles .
1210

Phase 12 - 1210 - choir (c) - 50 Units


Choir clerestory windows wider then below and the wall is set back over the horizontal moulding over the aisle windows; this clerestory level of the eastern wall was built on its own, with its clerestory vaulting caps, as can be seen in joints of each sid
Later

Phase 13 - Later


Choir clerestory windows wider then below and the wall is set back over the horizontal moulding over the aisle windows; this clerestory level of the eastern wall was built on its own, with its clerestory vaulting caps, as can be seen in joints of each side from within the roof.
