01
Objectives

A truly historical building, the New Hampshire state house is the oldest original capitol building in which the legislature still sits in its original chambers. Located in Concord the NH state house is known for its striking golden dome and war eagle perched at the apex. Recently DL King was contracted by the state of New Hampshire to begin renovations of the famed dome, including a complete repainting of the structure. Providing access to the dome of a very old historic building was a perfect fit for Seacoast Scaffold’s capabilities. After more than two years of attempting to secure approvals for a platform safe enough to handle the weight of the staging, scaffold erection began at the beginning of May 2016.

Objectives included:

  • Safely transporting equipment by crane onto the State House roof, which had weight restrictions in place.
  • To create a safe working structure with multiple deck levels for the contractor to utilize while painting the dome.

Approach

Being a very old and fragile building, weight restrictions were in place for the roof of the State House.  Turns out the grand old building had less framing than a typical modern house! With these restrictions in place, equipment had to be craned onto the roof and half-racks of gear would be spread out across the roof to help disperse the weight. Equipment was moved onto the roof 2-3 times per week as the erection crew deemed it necessary.

Furthermore, because the weight of the scaffold would not be supported by the State House roof, platforms were constructed for the staging to be built on. As mentioned above, these platforms were in the approvals processes for more than two years. Once approved, Seacoast Scaffold was able to begin work, starting with a base level circling the dome and building up. Because of delicate nature of the dome and using a paint that had been gilded, the staging was not allowed to touch the dome itself. This meant cantilevering out toward the dome from the staging, so the painters would be within a safe working reach.

  • Engineering was used to determine the platforms for the staging and how much weight could rest on the roof at any given time.
  • To work in the safest manner possible with Seacoast Scaffolder’s builders. This included wearing harnesses, as well as utilizing tie-off points and guardrails where necessary.

Results

Once the initial equipment was delivered and hoisted to the roof, the crew began the erection service of the staging. The ring pole system of scaffolding was used in order to allow more flexibility for rounding the dome and circling it with the staging. Guy wires were added and tested for tension to ensure the safe working ability of the scaffold. Once finished, the painting crews were able to get onto the staging themselves to begin repainting the State House’s dome. When the painting crew completed their job, Seacoast Scaffold returned to the capitol to provide the dismantle service of the scaffolding.
