Construction Backlog


Construction Backlog


The following represents the backlog of signed construction and engineering contracts in existence at March 31, 2021 and December 31, 2020, which represents the amount of revenue the Company expects to realize from work to be performed on uncompleted contracts in progress and from contractual agreements in effect at March 31, 2021 and December 31, 2020, respectively, on which work has not yet begun:










Balance - beginning of period










New contracts and change orders during the period









Adjustments and cancellations, net

(27,370 )












Less: contract revenue earned during the period










Balance - end of period










Backlog at March 31, 2021 included two contracts entered into during the third quarter of 2020 in the amount of approximately $4 million and approximately $2.95 million along with three contracts during the fourth quarter of 2020 in the amount of approximately $2.7 million, $0.80 million, and $0.70 million. In addition, the Company executed one large contract in the first quarter of 2021 in the amount of approximately $1.3 million. The Company expects that all of this revenue will be realized by March 31, 2023. Under the ELA, the Company cannot guarantee, but expects to receive, approximately $2.4 million in royalties for one such project. The Company expects to receive these royalties for this one such project through September 30, 2022. Backlog does not include expected royalty fees to the Company under the ELA from projects to be delivered by our licensee. 


The Company’s remaining backlog as of March 31, 2021 represents the remaining transaction price of firm contracts for which work has not been performed and excludes unexercised contract options. 

The Company expects to satisfy its backlog which represents the remaining unsatisfied performance obligation on contracts as of March 31, 2021 over the following period:


Within 1 year
$ 10,015,230

1 to 2 years


Total Backlog
$ 22,871,480

Although backlog reflects business that is considered to be firm, cancellations, deferrals or scope adjustments may occur. Backlog is adjusted to reflect any known project cancellations, revisions to project scope and cost and project deferrals, as appropriate.
