Update July 5, 2013

Excavation continues in the crawl space as evidenced by the light and dark color of the footings and foundation. The lighter colored/dry upper portions of the footings and foundation show how much of the footings and foundation was above grade prior to excavation. The darker colored/wet lower portions show how much soil has been excavated and removed.	Excavation in the crawl space is to allow access to aging waste lines and the installation of perforated pipe at the footing and foundation to collect ground water and runoff. New drain lines will collect and divert water to CBJ storm drains.
Other items in the crawl space requiring attention are miscellaneous electrical, data and communication lines. These will be replaced as needed during cable and wire management improvements.	Demolition of concrete and steel continues on the portico slab

Update June 21, 2013

Excavation slowly continues under the building while demolition is moving right along with the portico. Temporary steel ledger is in place, portico balusters and blocks have been removed and brick cladding is now being removed. 4th Street will be closed to traffic for the next two weeks starting on Monday, June 24, 2013, for demolition to the portico slab and sandstone cladding around the main entrance doors and windows.

Update June 14, 2013

This week excavation is taking place in the crawl space. As of yesterday four truckloads of soil have been hauled away equating to one truck per day far below their estimated six per day. The Project Manager brought up the subject at yesterday's meeting and talked with the General Contractor about it. They are aware and plan to step things up with additional equipment.

The shoring, work platform and safety railing is all in place at the portico. Some brick demo was performed to expose the concrete columns for installation of steel brackets. A saw cut into the brickwork was made for the steel angle iron. A steel beam/ledger will be installed onto brackets to support upper brick while lower brick, portico and sandstone cladding is removed. The steel ledger will remain in place until Phase II at which point it will be removed during cladding demolition.

Preliminary demolition has been performed to the sandstone railing/balusters. Major demo to the portico should begin on Wednesday, June 19, 2013, and take approximately one week. Excavation will continue in the crawl space until the predetermined amount has been removed.

The lower portion will be designated for contractor use for trucks and equipment to remove, load and haul away the excavated soil and debris.

Update June 7, 2013

Arete Construction removed cornerstone and excavated the soil (corner of 4th and Seward) to expose the footing and foundation. Core drilling and concrete cutting was performed to create access in and out of the crawl space. Portico granite slabs were shored up with timbers in preparation for metal shoring above. Metal shoring delivered to site and shoring installation begins.

Update May 31, 2013

The architects and project director met at the Capitol portico stairs to investigate the quality of the concrete foundations under the columns and stair stringers. It appears that the initial concrete pour up to about two feet below the ground floor and the concrete in the sub stringers is sound. There are some unexplained cracks and cold joints between pours that may need repair.

The architects recommend core drilling into the brick and mortar between the top of the column piers and the granite block supporting the columns to determine if the brick and mortar is continuous and its condition.

Hendricksen Construction, a subcontractor, probed alongside the landing slab using a #6 rebar and a jack hammer and reached resistance about 13 feet below grade which is consistent with the original drawing 400-E which shows a continuous footing under the portico at approximate elevation 59.0 (approximately 17 feet below ground floor).

The architects instructed the contractor to shore the granite landing and remove all the brick and loose and deteriorated concrete and mortar while we determine how best to re-construct the supports.
